Methodological review of multicriteria optimization techniques: aplications in water resources

Multi-criteria decision analysis (MCDA) is an umbrella approach that has been applied to a wide range of natural resource management situations. This report has two purposes. First, it aims to provide an overview of advancedmulticriteriaapproaches, methods and tools. The review seeks to layout the nature of the models, their inherent strengths and limitations. Analysis of their applicability in supporting real-life decision-making processes is provided with relation to requirements imposed by organizationally decentralized and economically specific spatial and temporal frameworks. Models are categorized based on different classification schemes and are reviewed by describing their general characteristics, approaches, and fundamental properties. A necessity of careful structuring of decision problems is discussed regarding planning, staging and control aspects within broader agricultural context, and in water management in particular. A special emphasis is given to the importance of manipulating decision elements by means ofhierarchingand clustering. The review goes beyond traditionalMCDAtechniques; it describes new modelling approaches. The second purpose is to describe newMCDAparadigms aimed at addressing the inherent complexity of managing water ecosystems, particularly with respect to multiple criteria integrated with biophysical models,multistakeholders, and lack of information. Comments about, and critical analysis of, the limitations of traditional models are made to point out the need for, and propose a call to, a new way of thinking aboutMCDAas they are applied to water and natural resources management planning. These new perspectives do not undermine the value of traditional methods; rather they point to a shift in emphasis from methods for problem solving to methods for problem structuring. Literature review show successfully integrations of watershed management optimization models to efficiently screen a broad range of technical, economic, and policy management options within a watershed system framework and select the optimal combination of management strategies and associated water allocations for designing a sustainable watershed management plan at least cost. Papers show applications in watershed management model that integrates both natural and human elements of a watershed system including the management of ground and surface water sources, water treatment and distribution systems, human demands,wastewatertreatment and collection systems, water reuse facilities,nonpotablewater distribution infrastructure, aquifer storage and recharge facilities, storm water, and land use

An Overview of Multi-Criteria Decision Analysis and the Applications of AHP and TOPSIS Methods

The integration of multiple technical, economic, environmental, and social criteria establishes Multi-Criteria Decision Analysis (MCDA) as a dependable decision-making tool in the context of interdisciplinary research. This study employs a literature-based methodology to illustrate how MCDA, particularly utilizing the Analytical Hierarchy Process (AHP) and TOPSIS models, has been utilized to tackle intricate decision-making issues. It also highlights the noteworthy discoveries derived from real-world applications, drawing upon previous research and case studies. This study explores the methodologies employed in the commonly utilized AHP and TOPSIS approaches, highlighting their broad applicability across various industries from 2000 to 2023. Additionally, a comprehensive examination of the applications of MCDA has been organized into five distinct sectors, namely supply chain, healthcare, business, resource management, and engineering & manufacturing

Eco-design decision making : towards sustainable engineering design of large made-to-order products

Sustainable design provides an holistic, life-cycle approach by which design engineers can minimise negative impacts and maximise positive impacts, thus ensuring that current industrial progress is not achieved at the expense of future generations. In the context of sustainable design, large made-to-order (LMTO) product sectors must address some unique issues: " The design process may be in the order of years, involving the client, the design contractors, co-venturers, suppliers and regulators. 9 The one-off nature of the design may limit the opportunity for reuse of design knowledge. 11 The existenceo f the possibility of catastrophico ut-of-envelopee ventsl eading to large scale safety and environmental impacts. " There is potential for high energy and resource consumption. " . Some LMTO products may cause local and transboundary environmental impacts. 0 There may be long term, post-decommissioning impacts. 0 Some aspects of the product life-cycle may give rise to impacts on social welfare. Engineering design is a process of decision making both during option synthesis and option selection. The first part of this research examined the current integration of environmental objectives and attributes with industrial design decision making processes using qualitative research methods. In particular, design selection was considered as the case-study focused on the activities of two case-study design contractors. The second part of the research proposed a framework to assist the consideration of environmental and societal impacts using transparent, systematic methodologies based on Multiple Attribute Decision Making (MADM) approaches. Two MADM methods were compared in relation to a case-study regarding the selection of an option for a produced water treatment system; Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) and Concordance and Discordance Analyses by Similarity to Ideal Solution (CODASID). Due to the subjectivity and uncertainty associated with information relating to sustainable design, a fuzzy set-based methodology was also investigated. In order to simulate the intuitive processes of human decision makers, the application of linguistic terms to evaluate sustainable design attributes was explored. This method was applied to a group decision making case-study to determine the best option for replacing a heat exchanger situated in a pond water cooling system. Comparisons were made between the fuzzy MADM method and the decision obtained from a group-based discussion. Finally, the third part of the research specifically addressed perceived risk attributed by the public to proposed large made-to-order products or processes, accommodating the societal element of sustainable design. Public risk perception was decomposed into measurable indices which were suitable for application to the fuzzy MADM method. The final aggregated evaluation, representing the overall perceived risk associated with the product in question, was then examined under different tolerance scenarios in order to make an informed judgement with respect to product viability. These three core research elements provide the foundation for managing the environmental and societal aspects of sustainable engineering design of large made-toorder products, thus providing an important addition to the wider concept of integrated product design.EThOS - Electronic Theses Online ServiceGBUnited Kingdo

Sustainability Assessment of Post-Mining Land Use Planning

Mining, by its nature, provides enormous investment to the mining nations and by extension contributes to the socio-economic development of the host communities. Where these communities exist, they remain a cause of concern since they are predominantly dependent on the economic opportunities generated by the mine. The Environmental Impact Assessment (EIA) functions in mining are somewhat of a risk reduction activity, even though the potential of halting projects is comparatively rare in situations where proposals are deemed to be of national interest and politically significant. This study highlights the environmental and socio-economic impact of lack of land use planning in host communities where the phenomenon of mine closure is a lived reality and evaluates alternative post-mining land use. In this study a case study, qualitative research approach is used to comparatively evaluate three mining EIA reports (EIA on the extension of mining operations at the Vlakvarkfontein Coal Mine; consolidation of high extraction mining impacts in the Trichardtsfontein; and rail loop, road diversion and pipeline project associated with Temo Coal) on the extent of post-mine land use consideration in the EIA process. Furthermore, the study, inter alia, assessed the extent to which the interested and affected parties' input was considered in EIA reports. In rehabilitation, the applicant is only reinstating the area, as closely as possible, to that which existed pre-mining, and should not be confused as post-mining land use. There is nothing new in providing for rehabilitation in EIA – it is a standard practice. However, the mining EIA reports extensively covered the environmental components, particularly the specialist studies, as they assessed whether projects conformed with the regulatory requirements. The emphasis of the mining EIA reports was mainly on the environmental component with – other than employment and economic benefits – no post-mining land use and socio-economic impact indicators. These trends were found to be further reinforced when the input of the interested and affected parties (I&APs) was analysed. In view of the findings of this study, the main recommendations to improve the EIA systems would be to clarify and simplify the mandates of the several institutions involved in the EIA process and system; and to improve and increase public access to EIA reports, including electronic means. This is pertinent due to the conspicuous absence of EIA reports in the public domain, which contributed to the limited number of EIA reports that were reviewed in this dissertation. In addition, public participation processes (PPP) should be conducted in most common languages of the stakeholders; and specialist social impact assessment should go beyond the traditional socio-economic issues faced by I&APs to include post-mining land use, as well as sustainable post-mining economy

A Customer-driven Decision Making Framework for Drinking Water Systems

According to the 2013 ASCE infrastructure report card, the USA potable water system needs an investment of $384.2 billion over the next 20 years to meet current and future needs. The American infrastructure, which has a GPA of D+ and rated as poor, needs an investment of$3.6 trillion for all infrastructure assets by 2020. One of the key proposed solutions was to prioritize the maintenance of infrastructure considering the Level of Service (LOS). Most of research works on water distribution network (WDN) focused on the condition or performance of water systems creating a gap between municipal goals and public expectations. It is evident that there is a lack of research in the area of LOS and its link with WDN condition. There is a vital need in municipalities to link renewal plans with the Level of Service. Therefore, the main objectives of the present research are to: 1) identify and study the factors that impact the LOS, 2) establish an assessment model for LOS in the WDN, and 3) map the LOS to WDN condition. Building upon recent work on the LOS of drinking water supply systems, the present research identifies LOS factors based on the review of water supply system (WSS) performance indicators from literature and experts in the domain. It consequently develops a framework that is dependent on two main models: (1) Best-Worst Method (BWM) model that determines the LOS of a WSS considering the relative weight of importance of the identified LOS factors and (2) Artificial Neural Network (ANN) model that maps the WDN condition to LOS. Using the water network data set of the city of Montreal, the framework is tested and the impact of pipe material and environmentalconditions on breakage rate is studied. This research proves that breakage rate varies significantly for different pipe materials and neighborhood areas with different environmental conditions. Questionnaire responses from the industry experts show that supply pressure and continuity, quality of supplied water, and customer complaints are the main factors that govern the quality of service. They also show that water quality is the most important factor to the LOS among the other significant factors. The relationship between WDN condition and LOS is determined considering the metrics of water quality, customer complaints, as well as pressure and continuity of water supply. An Artificial Neural Networks (ANN) model is developed in which the above metrics are considered the input variables and the LOS total score resulting from the developed BWM model is the output variable. The model is cross-validated using the embedded validation in the used software resulting in an R2 value of 0.871, which reflects a good representation of the relationship between the inputs and the outputs. Municipal management teams will be able to connect the technical world of condition assessment of WDN to the customer world by adopting a customer-oriented decision making process. This enables them to understand the customer perception of the provided service, optimize the budget allocation process and forecast the LOS based on the network condition. It also opens perspectives to key issues for future research work to diagnose the customer perception of municipal infrastructure performance. i

Multiple Criteria Analysis of the Life Cycle of the Built Environment

To design and achieve effective the life cycle of the built environment a complex analysis of its stages as well as stakeholders, their aims and potentialities is needed. The effect of micro, meso and macro environmental factors should also be taken into account. A thorough built environment’s life cycle (brief; design; raw material extraction, transport and processing; construction materials production and distribution; construction; use, repair and maintenance; demolition; disposal, reuse, or recycling) analysis is quite difficult to undertake, because a buildings and its environment are a complex system (technical, technological, economical, social, cultural, ecological, etc.), where all sub-systems influence the total efficiency performance and where the interdependence between sub-systems play a significant role. Various stakeholders (clients, users, architects, designers, utilities engineers, economists, contractors, maintenance engineers, built environment material manufacturers, suppliers, contractors, finansing institutions, local government, state and state institutions) are involved in the life cycle of the built environment, trying to satisfy their needs and affecting its efficiency. The level of the efficiency of the life cycle of the built environment depends on a number of variables, at three levels: micro, meso and macro level. The problem is how to define an efficient built environment life cycle when a lot of various parties are involved, the alternative project versions come to hundreds thousand and the efficiency changes with the alterations in the environment conditions and the constituent parts of the process in question. Moreover, the realization of some objectives seems more rational from the economic perspective thought from the other perspectives they have various significance. Therefore, it is considered that the efficiency of a built environment life cycle depends on the rationality of its stages as well as on the ability to satisfy the needs of the stakeholders and the rational character of environment conditions. Formalized presentation of the research shows how changes in the environment and the extent to which the goals pursued by various stakeholders are satisfied cause corresponding changes in the value and utility degree of a built environment life cycle. With this in mind, it is possible to solve the problem of optimization concerning satisfaction of the needs at reasonable expenditures. This requires the analysis of the built environment life cycle versions allowing to find an optimal combination of goals pursued and finances available. References to the most modern world scientific literature sources are presented in the monograph. The monograph is prepared for the researchers, MSc and PhD students of civil engineering, construction management and real estate development. The book may be useful for other researchers, MSc and PhD students of economics, management and other specialities.

A participatory multicriteria approach to evaluate strategic projects for local sustainable development

Tesis por compendio[EN] The dilemma of development and sustainability in the local context generates multiple interests and concerns. This dissertation arises from the challenge proposed by both concepts in the framework of decision making for urban planning. Its development has been guided by two main motivations. The first and most important is to discuss sustainable development in a context where little had been said, responding to how to improve the practices used for the prioritisation of actions during the planning stages of local development projects, taking as a case study the city of Cartagena de Indias (Colombia). The second, on the other hand, responds to the interest of contributing to the field of multicriteria decision making techniques. The objective is to design a methodology to help those responsible for territorial planning to evaluate development strategies and projects. In particular, it focuses on the participation of different stakeholders and on the approach to sustainable local development. Therefore, the general research question is: how can a participatory multicriteria methodology help to evaluate local development projects with a sustainable approach? To answer this research question the present dissertation, of an exploratory and descriptive nature, has been designed, and developed from the application of three cases of iterative and complementary studies. The objective has been to propose a framework that systematically allows the taking of decisions and the integration of diverse positions, without trying to find a unique solution with the best decision model. The proposed methodology has been developed from the combination of two techniques known from the field of Operations Research, Analytic Network Process (ANP) and Social Network Analysis (SNA). SNA is used to find out how the network of actors related to a problem is structured, to study and evaluate the relationships between the actors that make it up, to determine their degree of cohesion, the actors in the most relevant positions and the existing structural gaps. All of this permits the selection of participants in the decision making process carried out through ANP. ANP is a wellknown multicriteria decision method, which provides a framework for addressing decision making or problem assessment. It defines a prioritisation model as a network with complex, interdependent and feedback relationships between elements. The elements represent characteristics, requirements, conditions or criteria related to a problem, as well as possible alternative solutions. ANP is used to discover the opinions of the participants, to obtain their decision profiles and to reach a consensus on the prioritisation of projects and strategies. Additionally, this methodological proposal, based on the SNA-ANP combination, can be completed with other techniques, for example, geographic information systems to add some components that improve the decision. The results suggest that this SNA-ANP methodology is a novel and useful combination for evaluating local development plans with a multicriteria, sustainable and participatory approach. The results establish a basis for proposing new applications and generating new discussions with the local administration and other actors. With the inclusion of the local and sustainable development approach in the decision framework, throughout this dissertation, the value of different heritages is highlighted, as is the promotion of a more adapted strategic planning and the recognition and inclusion of multiple groups of actors. In addition, the use of practical and replicable methodologies that account for the results is promoted, to be applied at different scales, in order to improve planning and prioritisation of actions. The proposal has considered the dimensions of sustainability in decision models, the active participation of decision-makers and a better selection of participants. In short, it has facilitated the construction of a more participatory decision making process. Finally, it also allows us to explore future applications and to continue the discussion related to the problem of decision making during the planning and evaluation stages of strategic projects, whether for local sustainable development or for other types of objectives.[ES] El dilema del desarrollo y la sostenibilidad en el contexto local genera múltiples intereses e inquietudes. Esta disertación surge entorno al desafío propuesto por ambos conceptos en el marco de la toma de decisiones para la planeación urbana. Su desarrollo se ha orientado a partir de dos motivaciones principales. La primera y más importante es discutir sobre desarrollo sostenible en un contexto en el que se había hablado poco, respondiendo a cómo mejorar las prácticas utilizadas para la priorización de acciones durante las etapas de planeación de proyectos de desarrollo local, tomando como objeto de estudio la ciudad de Cartagena de Indias (Colombia). La segunda, por su parte, responde al interés por contribuir en el campo de las técnicas de toma de decisiones multicriterio. El objetivo es diseñar una metodología para ayudar a los responsables de la planificación territorial a evaluar estrategias y proyectos de desarrollo. En particular, se centra en la participación de diferentes partes interesadas y en el enfoque al desarrollo local sostenible. Por lo tanto, la pregunta general de investigación es: ¿Cómo puede una metodología multicriterio participativa ayudar a evaluar proyectos de desarrollo local con un enfoque sostenible? Para responder a esta pregunta de investigación se ha diseñado la presente disertación, de naturaleza exploratoria y descriptiva, desarrollada a partir de la aplicación de tres casos de estudios iterativos y complementarios. El objetivo ha sido proponer un marco que de forma sistemática permita tomar decisiones e integrar diversas posiciones, sin pretender hallar una solución única con el mejor modelo de decisión. La metodología propuesta se ha construido a partir de la combinación de dos técnicas conocidas del campo de la Investigación de Operaciones, el Proceso Analítico en Red (ANP) y el Análisis de Redes Sociales (SNA). El SNA se utiliza para conocer cómo se estructura la red de actores relacionados con un problema, estudiar y evaluar las relaciones entre los actores que la componen, determinar su grado de cohesión, los actores en posiciones más relevantes y los vacíos estructurales existentes. Todo ello permite seleccionar a los participantes en el proceso de toma de decisiones realizado a través del ANP. El ANP es un conocido método de decisión multicriterio, que proporciona un marco para abordar la toma de decisiones o la evaluación de problemas. Define un modelo de priorización como una red con relaciones complejas, interdependientes y retroalimentadas entre elementos. Los elementos representan características, requerimientos, condiciones o criterios relacionados con un problema, así como las posibles alternativas de solución. El ANP se utiliza para conocer las opiniones de los participantes, obtener sus perfiles de decisión y alcanzar un consenso sobre la priorización de proyectos y estrategias. Adicionalmente, esta propuesta metodológica, basada en la combinación SNA-ANP, se puede completar con otras técnicas, por ejemplo, los sistemas de información geográfica para agregar algunos componentes que mejoren la decisión. Los resultados sugieren que esta metodología SNA-ANP, es una combinación novedosa y útil para evaluar planes de desarrollo local con un enfoque multicriterio, sostenible y participativo. Los resultados establecen una base para proponer nuevas aplicaciones y generar nuevas discusiones con la administración local y otros actores. Con la inclusión del enfoque del desarrollo local y sostenible en el marco de las decisiones, a lo largo de esta disertación, se resalta el valor de distintos patrimonios, la promoción de una planeación estratégica más adaptada y el reconocimiento e inclusión de múltiples grupos de actores. Además, se promueve el uso de metodologías prácticas y replicables que den cuenta de los resultados, para ser aplicadas a diferentes escalas, con el fin de mejorar la planeación y la priorización de acciones. La propuesta ha considerado las dimensiones de la sostenibilidad en los modelos de decisión, la participación activa de los decisores y una mejor selección de los participantes. En síntesis, ha facilitado la construcción de un proceso de decisión más participativo. Finalmente, también permite explorar futuras aplicaciones y continuar la discusión relacionada con el problema de la toma de decisiones durante las etapas de planeación y evaluación de proyectos estratégicos sean para el desarrollo local sostenible o para otro tipo de objetivos.[CA] El dilema del desenvolupament i la sostenibilitat en el context local genera múltiples interessos i inquietuds. Aquesta dissertació sorgeix entorn al desafiament proposat per ambdós conceptes en el marc de la presa de decisions per a la planificació urbana. El seu desenvolupament s'ha orientat a partir de dues motivacions principals. La primera i més important és discutir sobre desenvolupament sostenible en un context en què s'havia parlat poc, responent a com millorar les pràctiques utilitzades per a la priorització d'accions durant les etapes de planificació de projectes de desenvolupament local, prenent com a objecte d'estudi la ciutat de Cartagena d'Índies (Colòmbia). La segona, per la seva banda, respon a l'interès per contribuir en el camp de les tècniques de presa de decisions multicriteri. L'objectiu és dissenyar una metodologia per ajudar els responsables de la planificació territorial a avaluar estratègies i projectes de desenvolupament. En particular, es centra en la participació de diferents parts interessades i en l'enfocament al desenvolupament local sostenible. Per tant, la pregunta general d'investigació és: Com pot una metodologia multicriteri participativa ajudar a avaluar projectes de desenvolupament local amb un enfocament sostenible? Per respondre a aquesta pregunta de recerca s'ha dissenyat la present dissertació, de naturalesa exploratòria i descriptiva, desenvolupada a partir de l'aplicació de tres casos d'estudi iteratius i complementaris. L'objectiu ha estat proposar un marc que de forma sistemàtica permeti prendre decisions i integrar diverses posicions, sense pretendre trobar una solució única amb el millor model de decisió. La metodologia proposada s'ha construït a partir de la combinació de dues tècniques conegudes del camp de la Investigació d'Operacions, el Procés Analític en Xarxa (ANP) i l'anàlisi de xarxes socials (SNA). El SNA s'utilitza per conèixer com s'estructura la xarxa d'actors relacionats amb un problema, estudiar i avaluar les relacions entre els actors que la componen, determinar el seu grau de cohesió, els actors en posicions més rellevants i els buits estructurals existents. Tot això permet seleccionar els participants en el procés de presa de decisions realitzat a través de l'ANP. L'ANP és un conegut mètode de decisió multicriteri, que proporciona un marc per abordar la presa de decisions o l'avaluació de problemes. Defineix un model de priorització com una xarxa amb relacions complexes, interdependents i retroalimentades entre elements. Els elements representen característiques, requeriments, condicions o criteris relacionats amb un problema, així com les possibles alternatives de solució. El ANP s'utilitza per conèixer les opinions dels participants, obtenir els seus perfils de decisió i arribar a un consens sobre la priorització de projectes i estratègies. Addicionalment, aquesta proposta metodològica, basada en la combinació SNA-ANP, es pot completar amb altres tècniques, per exemple, els sistemes d'informació geogràfica per afegir alguns components que millorin la decisió. Els resultats suggereixen que aquesta metodologia SNA-ANP, és una combinació innovadora i útil per avaluar plans de desenvolupament local amb un enfocament multicriteri, sostenible i participatiu. Els resultats estableixen una base per proposar noves aplicacions i generar noves discussions amb l'administració local i altres actors. Amb la inclusió de l'enfocament del desenvolupament local i sostenible en el marc de les decisions, al llarg d'aquesta dissertació, es ressalta el valor de diferents patrimonis, la promoció d'una planificació estratègica més adaptada i el reconeixement i inclusió de múltiples grups d'actors . A més, es promou l'ús de metodologies pràctiques i replicables que donin compte dels resultats, per ser aplicades a diferents escales, per tal de millorar la planificació i la priorització d'accions. La proposta ha considerat les dimensions de la sostenibilitat en els models de decisió, la participació activa dels decisors i una millor selecció dels participants. En síntesi, ha facilitat la construcció d'un procés de decisió més participatiu. Finalment, també permet explorar futures aplicacions i continuar la discussió relacionada amb el problema de la presa de decisions durant les etapes de planificació i avaluació de projectes estratègics siguin per al desenvolupament local sostenible o per a un altre tipus d'objectius.Gonzalez Urango, HK.

Sistema de medición del rendimiento para redes colaborativas de Pymes en el sector agroindustrial de Ecuador

[ES] La colaboración empresarial evidenciada en pequeñas y medianas empresas (Pymes) está contribuyendo a ampliar su competitividad, impulsar diversos procesos de innovación y mejorar su rendimiento; siendo, por tanto, fundamental la medición eficaz del rendimiento como una práctica estratégica para impulsar su desarrollo y eficiencia colectiva. La medición del rendimiento (MR) es un elemento esencial para la planificación efectiva y el control empresarial; así como para la toma de decisiones, a fin de desplegar diferentes acciones de mejora. La MR en Pymes incluye las siguientes tres categorías: las medidas de rendimiento o indicadores, el diseño del sistema de medición del rendimiento (SMR) y su desarrollo. El diseño del SMR para redes de Pymes es un proceso importante para asegurar que el marco de medición integre tanto, los factores y elementos del rendimiento propios del contexto colaborativo abordado, así como los métodos y técnicas para un proceso de medición del rendimiento balanceado y con alineamiento estratégico. Sin embargo, en la literatura fueron pocos los estudios que abordaban a la MR en contextos colaborativos. Entre aquellos que lo hacían, la mayoría se relacionaba con el direccionamiento hacia las mejores prácticas; lo que señaló dificultades en cuanto a la consideración de diversos factores entorno a este grupo de Pymes y con ello su implicación en el desarrollo de SMRs específicos. Otro aspecto importante en el diseño del SMR es la presencia de múltiples tomadores de decisión, espacio que tampoco evidenció mayor aporte entre la literatura revisada. Al considerar estos aspectos en el marco del diseño de SMRs para redes de Pymes en colaboración, ninguna investigación presentó un abordaje que contemple todas las características de forma simultánea. Considerando estas brechas, este trabajo de investigación tiene por objetivo proponer un sistema de medición del rendimiento para redes colaborativas de pymes (SMR - RECOP) en un escenario de toma de decisiones en grupo, considerando un enfoque de alineamiento estratégico. La propuesta tiene como finalidad integrar los principales factores de influencia del entorno de la red de Pymes, los requerimientos de medición básicos y la visión de un crecimiento sostenible enmarcado en la eficiencia colectiva. La propuesta de medición del rendimiento utiliza el Balanced Scorecard (BSC) como herramienta para direccionar la estrategia de la red al interior del sistema de medición, donde los indicadores se encuentran en alineación directa con los objetivos estratégicos; además, la técnica Fuzzy TOPSIS para apoyar el proceso de toma de decisiones en grupo que permite la determinación de los objetivos estratégicos y; por último, mesas de diálogo como los espacios para la discusión de ideas y formulación de indicadores de medición. Estas técnicas, juntamente con los elementos citados anteriormente son integrados en una metodología de tres fases. El sistema de medición propuesto se aplica en un caso de investigación para fines de validación; la red de Pymes evaluada pertenece al sector agroindustrial productor de cacao en Ecuador, donde los contextos empresariales tanto de red y cadena se evidencian como las estratégicas colaborativas con importante presencia. La aplicación empírica del SMR - RECOP mostró como resultados necesarios de su desarrollo a los siguientes productos: un conjunto de objetivos estratégicos; un procedimiento establecido para la definición y selección de estos objetivos en el marco de la toma de decisiones en grupo; un mapa estratégico consolidado y por último un conjunto de indicadores de rendimiento. Estos resultados muestran consistencia con los estamentos pretendidos por la red y su contexto de desarrollo; así como con los requerimientos que enmarcan un SMR para Pymes.[CA] La col·laboració empresarial evidenciada en petites i mitjanes empreses (Pimes) està contribuint a ampliar la seva competitivitat, impulsar diversos processos d'innovació i millorar el seu rendiment; sent, per tant, fonamental el mesurament eficaç de l'rendiment com una pràctica estratègica per impulsar el seu desenvolupament i eficiència col·lectiva. El mesurament de l'rendiment (MR) és un element essencial per a la planificació efectiva i el control empresarial; així com per a la presa de decisions, per tal de desplegar diferents accions de millora. La MR a Pimes inclou les següents tres categories: les mesures de rendiment o indicadors, el disseny de sistema de mesurament de l'rendiment (SMR) i el seu desenvolupament. El disseny de l'SMR per a xarxes de Pimes és un procés important per assegurar que el marc de mesurament integri tant, els factors i elements de l'rendiment propis de l'context col·laboratiu abordat, així com els mètodes i tècniques per a un procés de mesurament de l'rendiment balancejat i amb alineament estratègic. No obstant això, en la literatura van ser pocs els estudis que abordaven a la MR en contextos col·laboratius. Entre aquells que ho feien, la majoria es relacionava amb l'adreçament cap a les millors pràctiques; el que va assenyalar dificultats pel que fa a la consideració de diversos factors entorn a aquest grup de Pimes i amb això la seva implicació en el desenvolupament de SMRs específics. Un altre aspecte important en el disseny de l'SMR és la presència de múltiples prenedors de decisió, espai que tampoc va evidenciar major aportació entre la literatura revisada. A l'considerar aquests aspectes en el marc de el disseny de SMRs per a xarxes de pimes en col·laboració, cap investigació va presentar un abordatge que contempli totes les característiques de forma simultània. Considerant aquestes bretxes, aquest treball de recerca té per objectiu proposar un sistema de mesurament de l'rendiment per a xarxes col·laboratives de pimes (SMR - Recull) en un escenari de presa de decisions en grup, considerant un enfocament d'alineament estratègic. La proposta té com a finalitat integrar els principals factors d'influència de l'entorn de la xarxa de pimes, els requeriments de mesurament bàsics i la visió d'un creixement sostenible emmarcat en l'eficiència col·lectiva. La proposta de mesurament de l'rendiment utilitza el Balanced Scorecard (BSC) com a eina per adreçar l'estratègia de la xarxa a l'interior de el sistema de mesurament, on els indicadors es troben en alineació directa amb els objectius estratègics; a més, la tècnica Fuzzy TOPSIS per donar suport al procés de presa de decisions en grup que permet la determinació dels objectius estratègics i; finalment, taules de diàleg com els espais per a la discussió d'idees i formulació d'indicadors de mesurament. Aquestes tècniques, conjuntament amb els elements esmentats anteriorment són integrats en una metodologia de tres fases. El sistema de mesurament proposat s'aplica en un cas d'investigació per a fins de validació; la xarxa de Pimes avaluada pertany a el sector agroindustrial productor de cacau a l'Equador, on els contextos empresarials tant de xarxa i cadena s'evidencien com les estratègiques col·laboratives amb important presència. L'aplicació empírica d'el SMR - RECOP va mostrar com a resultats necessaris del seu desenvolupament als següents productes: un conjunt d'objectius estratègics; un procediment per a la definició i selecció d'aquests objectius en el marc de la presa de decisions en grup; un mapa estratègic consolidat i finalment un conjunt d'indicadors de rendiment. Els resultats obtinguts mostren consistència amb els estaments pretesos per la xarxa i el seu context de desenvolupament; així com amb els requeriments que emmarquen un SMR per a Pimes.[EN] The business collaboration evidenced in small and medium-sized companies (SMEs) is helping to expand their competitiveness, promote different innovation processes, and improve their performance. Therefore, effective performance measurement is essential as a strategic practice to promote its development and collective efficiency. Performance measurement (PM) is an essential element for effective business planning and control; as well as for decision making, in order to deploy different improvement actions. PM in SMEs includes the following three categories: performance measures or indicators, the design of the performance measurement system (PMS), and its development. The design of the PMS for SME networks is an important process to ensure that the measurement framework integrates both the factors and elements of the performance, which belong to the collaborative context addressed, as well as the methods and techniques for a balanced performance measurement process and with strategic alignment. However, in the literature, few studies addressed PM in collaborative contexts. Among those that did it, the majority was related to directing toward best practices; which pointed to difficulties in considering various factors around this group of SMEs and thus their involvement in the development of specific PMSs. Another important issue in the design of the PMS is the presence of multiple decision-makers, a space that did not show a greater contribution among the literature reviewed. When considering these aspects in the framework of PMSs design for collaborative SME networks, no research presented an approach that considers all the characteristics simultaneously. Considering these gaps, this research work aims to propose a performance measurement system for collaborative networks of SMEs (PMS - RECOP) in a group decision-making scenario, considering a strategic alignment approach. The purpose of the proposal is to integrate the main factors that influence the environment of the SMEs network, the basic measurement requirements, and the vision of sustainable growth framed in collective efficiency The performance measurement proposal uses the Balanced Scorecard (BSC) as a tool to direct the strategy of the network within the measurement system, where the indicators are in direct alignment with the strategic objectives. In addition, the Fuzzy TOPSIS technique supports the group decision-making process that allows the determination of strategic objectives and; finally, dialogue tables as spaces for the discussion of ideas and formulation of measurement indicators. These techniques, together with the elements aforementioned, are integrated into a three-phase methodology. The proposed evaluation system is applied in a research case for validation purposes; the network of SMEs evaluated belongs to the agro-industrial sector that produces cocoa in Ecuador, where the business contexts of both the network and the chain are evidenced as collaborative strategies with an important presence. The empirical application of the PMS - RECOP showed the following products as necessary results of its development: a set of strategic objectives, such as an established procedure for the definition and selection of these objectives within the framework of group decision-making; a consolidated strategic map, and finally a set of performance indicators. The obtained results showed consistency with the states intended by the network and its development context, as well as the requirements that frame a PMS for SMEs.Rojas Lema, XB. (2021).
