Any decision process deals with two different concerns as its cornerstones, evaluating the alternatives and ranking them based on their performances. In any decision process, the former phase is usually the premise of the latter one. Alternatives’ evaluation is the concept that largely depends on the experts and their expertise, which increase uncertainty in the decision-making process. In addition to all proposed methods for having the experts’ knowledge as evaluations of the alternatives, utilizing expert decision support systems (EDSS) can be a sensible response to such a need. Having evaluated the alternatives in the first phase of a decision-making process, the second phase of the process deals with the ranking the alternatives based on their performances obtained from the first phase. In this paper, we discuss the architecture of a fuzzy system including both modules, utilizing fuzzy concept for dealing with the uncertainty of the problem. Concerning the problem we had been dealt with, our system comprises a fuzzy evaluation module, which is a fuzzy expert system and an appropriate tool for evaluating the existing alternatives promptly and smoothly, without the imposed time delays by the experts to propose their comments and the uncertainty of such expertise-based comments, and a fuzzy ranking module, which is a fuzzy version of ELECTRE III method ranking the alternatives based on their outranking relations and by considering the existing uncertainty in their performances. This way the final ranking is resulted from an independent fuzzy system, which has considered the existing uncertainty in the evaluations not once but twice. Our proposed system has been applied to a real case of vendor selection process in one of the greatest and the most famous companies in the Iranian oil industry, OIEC, and the results are discussed.

- "Today, the used applied versions are known as ELECTRE II (Roy &Bertier, 1973), ELECTRE III (Roy, 1978) ELECTRE IV (Roy and Hugonnard, 1982) and ELECTRE TRI (Yu, 1992). ELECTRE method has been widely used in the literature in very different research fields (Wang and Triantaphyllou, 2008; Papadopoulos and Karagiannidis, 2008; Montazer et al., 2009; Sevkli, 2010; Certa et al, 2013; Rouyendegh and Erkan, 2013). In the present work ELECTRE III is proposedsince, in contrast to other adopted MCDM procedures, it is not compensative, which means that a very bad qualityscore in one service criterion cannot be compensated by good qualityscores in other service criteria.

ABSTRACT: Recent approaches to the service quality evaluation problem are focused on the employment of multi-criteria decisionmaking (MCDM) procedures, since processes related to service quality evaluation present meaningful communality elements to MCDM ones. Based on such assumption, in the present paper a new fuzzy MCDMapproach is developed tocomparatively evaluate passenger service quality of the international airports inSicily (Italy). In particular, by incorporating the respondents confidence level and degree of optimism on fuzzy assessments, quality scores of main airport service criteria are estimated, whereas ELECTRE multi criteria decision support methodis proposed to point out theservices quality rankingfor the considered airports, on the basis of which it is performed a strategic benchmarking of service quality. The developed approach represents an effective way to perform evaluation of airports service quality, since it can support airports management to understand and to explain the relatedservice quality ranking in terms of qualityscores of service criteria.
- "Other advantages of ELECTRE include the ability to take purely ordinal scales into account without the necessity of converting the original scales into abstract ones with an arbitrary imposed range (thus maintaining the original concrete verbal meaning), and the ability to take into consideration the decision makers' indifference and preference thresholds when modelling the imperfect knowledge of data. The ELECTRE method has been applied in many real world applications like education system (Giannoulis and Ishizaka, 2010), plant location selection (Ozcan et al., 2011), facility layout planning (Aiello et al., 2006), supplier selection (Montazer et al., 2009; Sevkli, 2010; Liu and Zhang, 2011), optimization of energy systems (Papadopoulos and Karagiannidis, 2008), material suitability (Shanian and Savadogo, 2006), contract selection (De Almeida, 2007) and risk sorting of pipelines (Britto et al., 2010). The proposed framework links ELECTRE approach with grey environment to provide a systematic process to arrive at a ranking list based on the environmental performance of member firms of supply chains.

ABSTRACT: Contribution of service supply chains to economic growth is significant and recent climate change issues expect services to be greener. The entire supply chain will be green if their suppliers adopt the requirements of the focal company and customers. Hence, it is essential that every organization constantly analyses and monitors the green performance of different members of the supply chains. Furthermore comprehensive studies have been carried out to identify criteria to evaluate green performance of manufacturing supply chain. However there is lack of studies to identify criteria and evaluate the performance of service supply chain. Service supply chain green performance evaluation necessitates methods to consider both qualitative and quantitative factors. Many conventional multi- criteria decision making (MCDM) methods have drawbacks such as inability to capture realistic fuzziness in decision making (human judgment), inadaptability to different levels of measurement, complexity in calculation and requirement of intricate details, which render them unsuitable for the task of environmental performance evaluation of service supply chains. In this paper, a grey based hybrid framework for evaluating the environmental performance of service supply chains is proposed by integrating grey based method with ELECTRE and VIKOR approaches. Two case studies were carried out to understand the effectiveness of criteria and method to evaluate environmental performance of service supply chains in a developing country context.

ABSTRACT: This paper presents a new, nonlinear, multicriteria, decision-making method: the characteristic objects (COMET). This approach, which can be characterized as a fuzzy reference model, determines a measurement standard for decision-making problems. This model is distinguished by a constant set of specially chosen characteristic objects that are independent of the alternatives. After identifying a multicriteria model, this method can be used to compare any number of decisional objects (alternatives) and select the best one. In the COMET, in contrast to other methods, the rank-reversal phenomenon is not observed. Rank-reversal is a paradoxical feature in the decision-making methods, which is caused by determining the absolute evaluations of considered alternatives on the basis of the alternatives themselves. In the Analytic Hierarchy Process (AHP) method and similar methods, when a new alternative is added to the original alternative set, the evaluation base and the resulting evaluations of all objects change. A great advantage of the COMET is its ability to identify not only linear but also nonlinear multicriteria models of decision makers. This identification is based not on a ranking of component criteria of the multicriterion but on a ranking of a larger set of characteristic objects (characteristic alternatives) that are independent of the small set of alternatives analyzed in a given problem. As a result, the COMET is free of the faults of other methods.
