A multiple criteria supplier segmentation using outranking and value function methods

[EN] Suppliers play a key role in supply chain management which involves evaluation for supplier selection problem, as well as other complex issues that companies should take into account. The purpose of this research is to develop and test an integrated system, which allows qualifying providers and also supplier segmentation by monitoring their performance based on a multiple criteria tool for systematic decision making. This proposal consists in a general procedure to assess suppliers based mainly on exploiting all reliable databases of the company. Firstly, for each group of products, their evaluation criteria are defined collaboratively in order to determine their critical and strategic performance, which are then integrated with other criteria that are specific of the suppliers and represent relevant aspects for the company, also classified by critical and strategic dimensions. Two multiple criteria methods, compensatory and non-compensatory, are used and compared so as to point out their strengths, weaknesses and flexibility for the supplier evaluation in different contexts, which are usually relevant in the supply chain management. A value function approach is the appropriate method to qualify providers to be included in the panel of approved suppliers of the company as this process depends only on own features of the supplier. On the other hand, outranking methods such as PROMETHEE have shown greater potential and robustness to develop portfolios with suppliers that should be partners of the company, as well as to identify other types of relationships, such as long term contracts, market policies or to highlight those to be removed from their portfolio. These results and conclusions are based on an empirical research in a multinational company for food, pharmaceuticals and chemicals. This system has shown a great impact as it represents the first supplier segmentation proposal applied to industry, in which decision making not only takes into account opinions and judgements, but also integrates historical data and expert knowledge. This approach provides a robust support system to inform operative, tactical and strategic decisions, which is very relevant when applying an advanced management in practice.This research has been partially developed with the support of the Ministry of Economy and Competitiveness (Ref. ECO2011-27369) and Ministry of Education (Marina Segura, scholarship of Training Plan of University Teaching).Segura, M.; Maroto, C. (2017).

Sustainable Technology Supplier Selection in the Banking Sector

Sustainable supplier selection is a key strategic problem in supply chain management. The aim of this research is to provide a new hybrid multicriteria model for evaluating technology suppliers and validate it with a case study in the banking sector. This approach allows companies to perform qualification, selection, ranking and sorting of suppliers on a sustainable basis. Integration of several techniques is necessary to address this complex decision problem with conflicting economic, environmental and social criteria. Analytic hierarchy process (AHP) is useful for problem structuring and weighting criteria collaboratively. Multi-attribute utility theory (MAUT) is applied to obtain indicators for product quality and supplier risks, whose utility functions are derived by data-driven models that favour evaluation objectivity and transparency. Preference ranking organisation method for enrichment evaluation (PROMETHEE) is suitable for supplier selection due to its discriminant power among alternatives. Finally, FlowSort is proposed to classify suppliers into ordered groups and the outcomes are compared with results from MAUT. Results show its applicability by increasing process transparency and reducing operational risks in practice

Multicriteria sorting method based on global and local search for supplier segmentation

The aim of this research is to develop a robust multicriteria method to classify suppliers into ordered categories and its validation in real contexts. The proposed technique is based on a property of net flows of the PROMETHEE method and uses global and local search concepts, which are common in the optimisation field. The results obtained are compared to those from the most cited sorting algorithm, and an empirical validation and sensitivity analysis is performed using real supplier evaluation data. Furthermore, it does not require additional information from decision-makers as other sorting algorithms do for assigning incomparable or indifferent alternatives to groups. An extension of the silhouette concept from data mining is also contributed to measure the quality of ordered classes. Both contributions are easy to apply and integrate into decision support systems for automated decisions in the supply chain management. Finally, this practical approach is also useful to classify customers and any type of alternatives or actions into ordered categories, which have an increasing number of real applications

Improving Food Supply Chain Management by a Sustainable Approach to Supplier Evaluation

[EN] Increasing food supply chain sustainability means having to deal with many conflicting aspects and involves producers, several departments in distribution companies, and consumers. The objectives of this research are to develop models to solve real-world supplier evaluation problems and validate them with real data on fresh fruits in a supermarket chain. Literature review and results from a survey with managers from purchasing, logistics, and quality departments of a food distribution company are used to establish criteria, to first model the assessment of products and, second, to model supplier evaluation. A multicriteria hybrid approach is proposed, using multi-attribute utility theory (MAUT) to assess the quality of products and Preference Ranking Organisation Method for Enrichment Evaluation (PROMETHEE) to complete their evaluation with strategic criteria to be included in the second phase. The results allow companies to rank suppliers by product and classify them according to the main criteria categories, such as product strategy, food safety, economic, logistic, commercial, green image and corporate social responsibility. A sorting approach is also applied to obtain ordered groups of suppliers. Finally, the models proposed can form the core of a decision support system in order to create and monitor the supplier base in food distribution companies, as well as to inform sustainable decision making.This research was funded by the Regional Ministry of Education, Research, Culture and Sport of the Autonomous Government of the Valencian Region, Spain, grant number AICO/2017/066.Segura Maroto, M.; Maroto Álvarez, MC.; Segura García Del Río, B.; Casas-Rosal, JC.

Quantifying the Sustainability of Products and Suppliers in Food Distribution Companies

[EN] Supplier evaluation is a relevant task of supply chain management where multicriteria methods make great contributions to manufacturing industries. This is not the case in food distribution companies, which have a key role in providing safe and affordable food to society. The purpose of this research is to measure the sustainability of products and suppliers in food distribution companies through a multiple criteria approach. Firstly, the system proposed provides indicators to qualify products and assess the food quality, using the compensatory Multi-Attribute Utility Theory (MAUT) model. Secondly, these indicators are included in supplier evaluation, which takes economic, environmental, and social criteria into account. MAUT and Preference Ranking Organisation Method for Enrichment Evaluation (PROMETHEE), a non-compensatory method, are used for supplier evaluation. This approach has been validated for fresh food in a supermarket chain, mainly using historical data. Partial indicators, such as food safety scores, together with global indicators of suppliers, inform the most appropriate decisions and the most appropriate relations between companies and providers. Poor performance in food safety can lead to the disqualification of some suppliers. MAUT is good for qualifying products and is easy to apply at the operational level in logistic platforms, while PROMETHEE is more suitable for supplier segmentation, as it helps to identify supplier strengths and weaknesses.This research was funded by the Regional Ministry of Education, Research, Culture and Sport of the Autonomous Government of the Valencian Region, Spain, grant number AICO/2017/066.Segura Maroto, M.; Maroto Álvarez, MC.; Segura García Del Río, B.

Preferencias y rendimiento de los alumnos en el aprendizaje de Investigación Operativa con videos

[EN] The increasing supply of videos as an online resource has changed the performance of students who study degrees based on face-to-face learning. The objectives of this paper are to elicit current preferences for different types of learning resources, especially videos, developed to teach Operations Research in Business Administration and Management degree, as well as analysing the relation between the videos use and students’ performance. The methodology is based on a survey using the Likert scale and the multicriteria method AHP. While all available resources are used to learn the subject, the results show a predominant preference for exam answers and videos, although more than one third of the students also use books and slides. Detailed exam answers improve learning and decrease tutorial appointments. There are significant differences in the use of learning resources among groups and resources affect students’ behaviour and performance. The videos with teaching modules decrease face-to-face class attendance, while the videos with interactive case studies affect performance positively. Therefore, we think that moving forward in this line would improve effective learning.[ES] La creciente oferta de videos como recurso online ha modificado el comportamiento de los alumnos que cursan titulaciones con docencia presencial. Los objetivos de este trabajo son cuantificar las preferencias actuales por los diversos tipos de materiales, y en particular los videos, elaborados para la docencia de Investigación Operativa en el Grado en Administración y Dirección de Empresas, así como analizar la relación entre el uso de videos y el rendimiento de los alumnos. La metodología se basa en una encuesta con la escala de Likert y la técnica AHP. Si bien todos los recursos disponibles se utilizan para preparar la materia, los resultados muestran una preferencia mayoritaria por los exámenes resueltos y videos, aunque más de un tercio de los alumnos también utilizan libros y presentaciones. Los exámenes resueltos mejoran el aprendizaje y reducen las tutorías. Se han encontrado diferencias significativas en el uso de los recursos por grupo y los medios utilizados también afectan al comportamiento y al rendimiento de los alumnos. Los videos con unidades didácticas reducen la asistencia a clase presencial, mientras que los videos de casos prácticos interactivos afectan positivamente al rendimiento. Por tanto, creemos que avanzar en esta última línea mejoraría el aprendizaje efectivo.Segura Maroto, M.; Maroto Álvarez, MC.; Ginestar Peiro, CDM.; Navarro Cerdán, JR. (2018).

Preferencias en el aprendizaje de Investigación Operativa: Docencia inversa y presencial

[EN] The use of online resources for learning is increasing in business higher education, not only in the flipped classroom approach but also in order to supplement face-to-face lectures. The objectives of this paper are eliciting students’ preferences and assessing the learning resources (books, slides and videos) in teaching the Operations Research in Business Administration and Management degree. The students’ preferences have been obtained using Analytic Hierarchy Process, a quantitative method, appropriate for eliciting and aggregating individual preferences to provide information from a group of people. In addition, the use and assessment of the teaching resources have been analysed using the Likert scale, a qualitative method frequently used in higher education studies. The students who prefer videos the most are those from flipped classroom, although the videos have also affected students from traditional face-to-face teaching. In general, the slides, which synthesize and outline the concepts being studied, represent the resources more used by students of face-to-face groups. Nevertheless, there are significant differences amongst the students’ preferences by group. Finally, the videos also contribute to students skills, mainly in autonomous learning. The results and the students’ suggestions encourage the teachers to continue developing additional videos with case studies and real applications.[ES] La creciente utilización de los recursos en línea en la formación de administración y dirección de empresas aparece tanto en el modelo de docencia inversa como complemento a la docencia presencial. Los objetivos del trabajo son obtener las preferencias de los alumnos y valorar los recursos docentes (libros, diapositivas y videos) en el aprendizaje de Investigación Operativa del Grado de Administración y Administración de Empresas. Las preferencias se han obtenido mediante AHP, método cuantitativo apropiado para obtener y agregar preferencias individuales, generando preferencias agregadas de grupo. Además, hemos analizado los recursos docentes mediante la escala de Likert, método cualitativo muy utilizado en los estudios de educación superior. Los alumnos que prefieren más los videos son los de docencia inversa, aunque los videos también han influido en los estudiantes de docencia presencial. En general, las diapositivas, que sintetizan los conceptos, representan el recurso más utilizado en la docencia presencial. Sin embargo, existen diferencias significativas entre las preferencias de los alumnos por grupo. Por último, los videos también contribuyen a la adquisición de competencias, principalmente al aprendizaje autónomo de los alumnos. Los resultados y las sugerencias recibidas nos animan a seguir desarrollando videos con casos prácticos y aplicaciones reales.Bas, MDC.; Segura Maroto, M.; Ginestar Peiro, CDM.; Maroto Álvarez, MC.

Factores explicativos del nivel de endeudamiento de las empresas españolas: un análisis con datos de panel

The relation between the decisions of investment and financing, as well as its influence in the value market of the company, has motivated that in the last years many studies have based on the analysis of the capital structure. In this line, the aim of this paper is to contrast empirically, by means of the panel data methodology, the different factors that can explain the level of debt, using for it a sample constituted by not financial firms who have quoted in the Spanish Stock Exchange during the period 1990-1999.Financing policy, capital and ownership structure, panel data

Evaluación interactiva del aprendizaje de Investigación Operativa basada en juegos mediante la plataforma Kahoot!

[EN] Emerging technologies and mobile platforms allow the introduction of new teaching and learning strategies, in particular new ways to implement games in higher education. Kahoot! is a free platform, which can be used by teachers to develop games for classroom activities. Although this tool is the most used mobile app and one of the first to be used in education, there are no studies about its application in learning Operations Research. The objective of this paper is to evaluate Kahoot's capabilities for continuous assessment, as well as its contribution in improving students´ motivation, learning and performance in decision making tecniques. As positive outcomes we can highlight that the majority of students think Kahoot is a fun experience and that it is also useful when revising concepts. Moreover, Kahoot games increase student´engagement and provide immediate feedback for both teacher and student. In addition, results about student´s performance and motivation are presented.[ES] Las nuevas tecnologías y aplicaciones móviles facilitan la implantación de nuevas estrategias de enseñanza-aprendizaje y en particular nuevas formas de implementar juegos en educación superior. Kahoot! es una plataforma gratuita con la que el profesor puede crear juegos para utilizar en el aula. Aunque esta herramienta es la aplicación móvil más utilizada y una de las primeras en educación, no hay estudios publicados sobre su utilización en el apredizaje de Investigación Operativa. El objetivo de este trabajo es la evaluación de las prestaciones de Kahoot para la evaluación continua, así como la contribución de esta herramienta para mejorar la motivación, el aprendizaje y el rendimiento de los alumnos en las técnicas de toma de decisiones empresariales. Como resultados positivos podemos destacar que la mayoría de los alumnos consideran que es divertido, que representa una buena herramienta para repasar conceptos. Además aumenta la participación durante las clases y aporta un feedback inmediato tanto al alumno como al profesor. Asimismo, presentamos resultados sobre el rendimiento y la motivación de los alumnos.Segura Maroto, M.; Maroto Álvarez, MC.; Ginestar Peiro, CDM.; Navarro Cerdán, JR.; Martón Lluch, I. (2019).

Sustainable Forest Management in a Mediterranean region: Social preferences

Forest Systems is an Open Access Journal.

The main purpose of this work is to define the strategic criteria and objectives for sustainable forest management and aggregate the preferences of stakeholders in a Mediterranean region, using AHP and Goal Programming. Area of study: Valencian Community (Spain). Material and Methods: Firstly, we identified forest stakeholders and structured a decision hierarchy. Then a workshop was carried out to test and validate the proposed criteria and objectives, as well as a survey to determine social preferences. Secondly, another survey was conducted amongst experts to prioritize action plans. Main results: Stakeholders preferences gave the greatest importance to the environmental criteria (hydrological regulation and erosion, climate change mitigation and biodiversity) with an average weight of 40%. Social criteria (employment, recreational activities and landscape) had a weight of 38% and 22% the economic criteria case (wood, hunting and fishing, livestock, renewable energies, rural tourism and mining). The results showed that new products and services such as tourism, renewable energies, landscape, hydrological regulation and erosion control, biodiversity or climate change mitigation are very relevant objectives. We also prioritized action plans comparing them with the distribution of the administration budget. Research highlights: The environmental and social criteria are much more important than the economic ones in the regional planning of the Mediterranean forest, regardless of the method used to aggregate the social preferences and if the forest is public or private.The authors acknowledge the support received from the Ministry of Science and Innovation through the research projects Ref.
