fuzzy edas method

This paper provides a practical method to collect the opinion and experience of experts and use them to make decisions in the field of choosing the best options for maintenance and repairs. In the proposed method, first, the opinions of experts are collected and aggregated, and using the basics of failure modes and effects analysis (FMEA), this information is summarized and expressed in the form of decision-making criteria. In the following, the maintenance and repair approaches for each of the failure modes are ranked according to the required resources and the expected results from their implementation, using the fuzzy EDAS method. The proposed approach has been used for the set of compressors of Ilam Petrochemical Utility Unit. In this regard, firstly, the failure modes, which cause disruptions in the performance and, as a result, the compressors being taken out of service, have been examined, and among them, the consequences of five critical failure modes have been selected to being examined, based on the OREDA standard and the opinion of experts. The consequences of these failure modes on the compressor performance and finally their effects on the production process have been analyzed. Solutions have been proposed to deal with each of these failures and these solutions have been ranked.

Evaluation of marketing channels is a very important and complex task, so far no comprehensive model has been presented in this regard. The present study aims to provide a decision framework for evaluating marketing channels.
With extensive study of literature, effective indicators were identified in the evaluation of marketing channels. Then, the newest multi-criteria decision-making method, fuzzy best-worst method was used to calculate the relative importance of indices. In addition, Fuzzy EDAS technique was applied as a multi-attribute decision-making method to rank distribution strategies in marketing channels. The statistical population of this research consists of directors and experts in the food industry, which due to their limited number, sampling was not performed.
Eight criteria were identified for evaluating marketing distribution channels, including trust, conflict, display, delivery, information exchange, product return cost, coordination cost, and profitability as well. Six types of marketing channels are: highlighting the importance of the sales team, expanding the sales team, distributing value added, ordinary distributors, the exclusive web channel, and the shared web channel.
According to the result of research conducted by a food company, the strategy of expanding the sales team has first ranked among other strategies.
