Economic, Ecological and Social Analysis Based on DEA and MCDA for the Management of the Madrid Urban Public Transportation System

The aim of this research is to help public transport managers to make decisions on the type of buses that should compose their public transport fleet, taking into account economic, environmental and social criteria from the point of view of sustainability. This paper fills a knowledge gap by including the social dimension of sustainability in addition to the economic and environmental dimensions. The original nature of this study lies in analyzing complementarities in the structuring of an efficiency and multicriteria problem. Our research analyzes Madrid public bus system data; the problem is structured in a comparative way between two analytical methods, a Data Envelopment Analysis (DEA) and an ELimination Et Choice Translating REality (ELECTRE) III. Our research results show that two main groups of vehicles could play a part in part the theoretical solution. The main conclusions of this research are that (a) plug-in and induction electric vehicles are not comparable to GNC and diesel–hybrid vehicles in terms of cost, pollution and service; and (b) the ELECTRE III model provides more information in solving this problem than the DEA model.

Ranking jerárquico del índice Dow Jones usando el método ELECTRE-III

El objetivo del artículo es presentar un enfoque de proceso jerárquico multicriterio para la toma de decisiones en la selección de acciones de las principales empresas que cotizan en el índice Dow Jones. Uno de los problemas que suelen enfrentar los inversores es decidir qué acciones deben incluirse en un portafolio de inversión. El artículo permite a los inversores dar respuesta a esa pregunta, mediante un enfoque jerárquico y el método ELECTRE III utilizando diferentes criterios basados en las ratios financieras de rentabilidad, liquidez, mercado y eficiencia. En este proceso el inversor genera un ordenamiento a un nivel global y un ordenamiento en subgrupo de criterios considerando sus preferencias.

An approach to optimize container locations in a containership with Electre III

In this article, we treat the problem of container storage in the export direction, exactly in the containership loading process. We propose an approach to the problem of container placement in a containership by describing a decision model to help decision-makers (handling operators) to minimize the total containers shifting. This is obtained by using a multicriteria decision method named Electre III (Elimination and Choice Expressing Reality) to identify the best location of any container. Here, we consider four criteria: the container destination, the container weight, the departure date of the container and the container type. This method has as input a matrix of performance and the subjective parameters and gives a ranking of alternatives as an output.

An integrated ANP-ELECTRE III decision model applied to eco-friendly car selection

The number of green energy options in different fields is growing because of the need for reducing energy consumption and eliminating gas emission. One of these options is the use of eco-friendly cars produced by various manufacturers. Given the many available options and conflicting evaluation criteria, evaluation of such options becomes complex, and different multi-criteria decision-making (MCDM) approaches have been used to select the most suitable car in terms of eco-friendly car selection. Previous research has been somewhat limited with respect to consideration of interdependencies between evaluation criteria and multi-levels of preference. This paper proposes a new integrated MCDM approach with the capability for considering interdependent criteria for eco-friendly car evaluation and different levels of preference. An analytic network process (ANP) will be used to evaluate the levels of importance of interdependent criteria, and ELECTRE III will be modeled to include thresholds of preference. The introduced model, based on twenty-eight evaluation criteria, was demonstrated in a case study dealing with five alternative electric and hybrid cars. The results from this model were compared to a traditional decision-making method and better results were obtained from the model. The model can help users make proper decisions regarding their future car options in a comprehensive manner. Sensitivity analysis showed the robustness of the model under different setups.

PENENTUAN SISTIM TRASPORTASI UNGGULAN DI KAWASAN PENGEMBANGAN EKONOMI TERPADU (KAPET) SERAM PROVINSI MALUKU

Abstrak Sejak bergulirnya kebijakan pemerintah pusat tentang percepatan pembangunan Kawasan Timur Indonesia, yang ditindak lanjuti dengan pembentukan Kawasan Pengembangan Ekonomi Terpadu (KAPET) Seram tahun 1998.yang kegiatannya baru dimulai tanggal 7 Agustus 2001 dengan terbentuknya Badan Pengelola Kapet Seram. Badan ini belum dapat berbuat banyak mengingat luasnya wilayahnya, beragamnya masalah yang dihadapi diantaranya masalah transportasi. Kendala kendala tersebut perlu dianalisa, dikaji secara mendalam baik sistem, dimensi maupun sarana transportasi guna pengembangan dan peningkatan perekonomian masyarakat. Berdasarkan data potensi daerah maupun sarana dan prasarana penunjang, serta tanggapan masyarakat akan pentingnya sistem, dan sarana transportasi, maka dengan bantuan metode AHP (Anatityc Herarchi Proces) dan software ELECTRE III dapat diproses dan diperoleh kriteria yang memiliki ranking tertinggi serta penentuan alternatif terbaik dari beberapa alternatif moda transportas yang ditawarkan untuk berbagai pihak. Ternyata hasil olahan program dalam penentuan keputusan sistem transportasi dari 12 (dua belas) kriteria terdapat 5 (lima) kriteria yang memiliki ranking tertinggi dan melalui software ELECTRE III didapat diranking alternatif terbaik dari 4 (empat) alternatif adalah L4 (Transportasi /Moda terpadu). Kiranya penelitian ini tidak dijadikan sebagai hasil akhir, melainkan awal dari penelitian-penelitian selanjutnya

A DECISION MODEL PROPOSAL IN CASE OF UNCERTAINTY: PHOTOCOPY MACHINE SELECTION WITH ENTROPY-BASED ELECTRE III METHOD

Decision making is getting more complex and difficult in our daily life and business life. However, correct and fast decision making is the first condition of managing and directing. The complexity and uncertainty in decision problems have increased as a result of technological developments and changes in consumer demands. Most of the decision problems encountered contain many criteria. Multi-Criteria Decision Making (MCDM) is to choose the most suitable alternative among many alternatives according to more than one determined criteria. Various methods have been developed for the solution of multi-criteria decision problems. ELECTRE III (ELimination Et Choice Translating REality) method, one of these methods, is one of the most widely used methods. The ELECTRE III method is a method used in the solution of decision problems involving uncertainty. In this study, the ELECTRE III method and its properties have been examined with an application. For this purpose, the problem of photocopy machine selection was examined with the ELECTRE III method in this study. The ENTROPY method was used to determine the weights of the criteria used in the decision problem and the ELECTRE III method was used to rank the copier machine options.
