An Analytic Hierarchy Process for The Evaluation of Transport Policies to Reduce Climate Change Impacts

Transport is the sector with the fastest growth of greenhouse gases emissions, both in developed and in developing countries, leading to adverse climate change impacts. As the experts disagree on the occurrence of these impacts, by applying the analytic hierarchy process (AHP), we have faced the question on how to form transport policies when the experts have different opinions and beliefs. The opinions of experts have been investigated by a means of a survey questionnaire. The results show that tax schemes aiming at promoting environmental-friendly transport mode are the best policy. This incentives public and environmental-friendly transport modes, such as car sharing and car pooling.Analytic Hierarchy Process, Transport Policies, Climate Change

Multicriteria Evaluation Of Tourism Potential In The Central Highlands Of Vietnam: Combining Geographic Information System (GIS), Analytic Hierarchy Process (AHP) And Principal Component Analysis (PCA)

Tourism potential provides an indication for the tourism development opportunities of regions and sites. This paper deals with a multicriteria evaluation of the tourism potential in the Central Highlands of Vietnam. The study area is located in the Southeast Asian monsoon tropical climatic zone, and offers both natural and cultural tourism resources. GIS-based cost distance analysis was used to calculate the travel time along the road and using other transportation networks. Then an Analytic Hierarchy Process (AHP) was applied to determine a weighting coefficient for each criterion in multicriteria evaluation. Principal Component Analysis (PCA) was processed next to AHP, allowing combination of the internal and external tourism potentials of the considered sites. Both AHP and PCA approaches were based on a certain number of alternatives, and take multiple criteria and conflicting objectives into consideration. The results show that the Central Highlands have considerable potential for tourism development at 99 potential eco-tourism sites and 45 potential cultural tourism sites. However, the region is now faced with poor tourism infrastructure with low external potential. An improvement of tourism infrastructure, service quality, and strengthened linkages with other tourist sites is indicated to diversify the tourism products and increase the attractiveness of regional destinations

A MODEL FOR RANKING RAILWAY INFRASTRUCTURE PROJECTS

Realizacija prometnih projekata složen je investicijski poduhvat, koji je poseban izazov i za menadžere i za inženjere. Prometni projekti, kao projekti u javnom sektoru, uključuju veći broj interesnih skupina, čije želje treba uzeti u razmatranje prilikom njihove evaluacije. Zbog raznovrsnih kriterija i postavljenih ciljeva interesnih skupina predlaže se primjena višekriterijskih pristupa za selekciju i rangiranje prometnih projekata. U ovom su radu pored definiranih relevantnih interesnih skupina predloženi i određeni kriteriji za rangiranje željezničkih infrastrukturnih projekata. Poseban je doprinos rada analiza utjecaja relevantnih vanjskih projekata na rangiranje. Kao višekriterijski pristup pogodan za analizu problema s mrežnom strukturom primijenjen je analitički mrežni proces. Model sadrži četiri klastera: alternative, kriterije, interesne skupine i relevantne eksterne projekte. Klasteri, kao i njihovi elementi, su u korelaciji, što strukturu modela čini mrežom. Model je primijenjen na primjeru željezničkih pruga Republike Srbije.Realizing transport projects is a complex investment endeavour, which is a special challenge for both managers and engineers. Transport projects, as projects within the public sector, include a larger number of interest groups, whose wishes should be considered during their evaluation. Due to multiple criteria and set goals of interest groups, an application of multi-criteria approaches for the selection and ranking of transport projects is proposed. This paper, together with defined relevant interest groups, also proposes certain criteria for ranking railway infrastructure projects. A special contribution of this paper is the analysis of influences, which relevant external projects make on ranking. As a multiple-criteria approach, suitable for analysis of problems with network structure, an analytical network process was applied. The model contains four clusters: alternatives, criteria, interest groups and relevant external projects. Clusters, as well as their elements, are correlated, which makes the structure of the model into a network. The model has been applied on the example of the railway lines in the Republic of Serbia

The state of the art development of AHP (1979-2017): A literature review with a social network analysis

Although many papers describe the evolution of the analytic hierarchy process (AHP), most adopt a subjective approach. This paper examines the pattern of development of the AHP research field using social network analysis and scientometrics, and identifies its intellectual structure. The objectives are: (i) to trace the pattern of development of AHP research; (ii) to identify the patterns of collaboration among authors; (iii) to identify the most important papers underpinning the development of AHP; and (iv) to discover recent areas of interest. We analyse two types of networks: social networks, that is, co-authorship networks, and cognitive mapping or the network of disciplines affected by AHP. Our analyses are based on 8441 papers published between 1979 and 2017, retrieved from the ISI Web of Science database. To provide a longitudinal perspective on the pattern of evolution of AHP, we analyse these two types of networks during the three periods 1979?1990, 1991?2001 and 2002?2017. We provide some basic statistics on AHP journals and researchers, review the main topics and applications of integrated AHPs and provide direction for future research by highlighting some open questions

A Review of Multi-Criteria Assessment of the Social Sustainability of Infrastructures

[EN] Nowadays multi-criteria methods enable non-monetary aspects to be incorporated into the assessment of infrastructure sustainability. Yet evaluation of the social aspects is still neglected and the multi-criteria assessment of these social aspects is still an emerging topic. Therefore, the aim of this article is to review the current state of multi-criteria infrastructure assessment studies that include social aspects. The review includes an analysis of the social criteria, participation and assessment methods. The results identify mobility and access, safety and local development among the most frequent criteria. The Analytic Hierarchy Process and Simple Additive Weighting methods are the most frequently used. Treatments of equity, uncertainty, learning and consideration of the context, however, are not properly analyzed yet. Anyway, the methods for implementing the evaluation must guarantee the social effect on the result, improvement of the representation of the social context and techniques to facilitate the evaluation in the absence of information.This research was funded by the Government of Chile under the Doctoral Fellowship Program Abroad (grant CONICYT-2015/72160059), the project DIUFRO DI14-0096 and the Spanish Ministry of Economy and Competitiveness along with FEDER funding (Projects BIA2014-56574-R and BIA2017-85098-R).Sierra-Varela, LA.; Yepes, V.; Pellicer, E.

A multi-criteria sustainability assessment for biodiesel and liquefied natural gas as alternative fuels in transport systems

The incorporation of clean-fuel technologies has become essential for the sustainability of the transportation sector. Natural gas technology, especially the use of liquefied natural gas (LNG), has become a possible alternative to diesel oil in freight transport because of its acceptable autonomy and low fuel prices. For the introduction of this alternative fuel, freight companies need tools that allow them to perform an integrated assessment of relevant aspects related to environment, economy and social responsibility. This paper introduces a multi-criteria based methodology that integrates the key factors involved in the transport system: vehicles, infrastructure and fuels, and consideration of the three pillars of sustainability, as well as the reliability of technology, legislation and market issues. In particular, a case study for the impact assessment of LNG in comparison to hydrotreated vegetable oil (HVO) and diesel oil as regular long-haul freight transport fuels in Spain was developed. The information for the comparison process was obtained from peer-reviewed articles and reports from international and Spanish institutions, while the primary data was obtained through semi-structured in-depth interviews to the different stakeholders. A weighted sustainability index for each alternative was developed to integrate the data obtained through the analytic hierarchy process. The results indicate that LNG trucks would be an attractive option compared to diesel oil and HVO, provided that decision-makers give significant weight to social and environmental criteria, and that the government guarantees a legislative security to maintain the low taxes on natural gas. Integration of stakeholders allows making the most appropriate decision according to the objectives of the company. The application of the proposed methodology shows consistent results, which should ensure the success of a long-term alternative in the dynamic market for transportation fuels

Desarrollo de un modelo para la selección estratégica de proyectos basado en el Proceso Analítico Jerárquico (AHP)

En este TFG hemos desarrollado e implementado un modelo para la selección estratégica de proyectos con la innovación de integrar la metodología AHP con otra de las técnicas de selección y evaluación de proyectos como es la Programación Monobjetivo. Previamente se ha realizado un recorrido por las principales técnicas de selección y evaluación de proyectos, centrándonos en qué consisten, ejemplos, ventajas, desventajas, etc. Además se ha desarrollado un capítulo que versa sobre el estándar que muchas empresas utilizan para alinear sus proyectos con su estrategia. Con todo eso realizado previamente, se ha elaborado un apartado solo para la metodología AHP focalizándonos sobre todo en el funcionamiento en sí de la misma para poder estar en condiciones de realizar y explicar cómo se han desarrollado las implementaciones del supuesto en Excel. Por último se han desarrollado dos estudios económicos, uno para que el lector pueda conocer de manera aproximada cuánto le podría suponer a una empresa llevar a cabo una implementación parecida a la nuestra y el otro un estudio económico sobre el TFG al completo.Departamento de Organización de Empresas y Comercialización e Investigación de MercadosGrado en Ingeniería en Organización Industria
