همواره مهمترین عامل در تعیین وضعیت اعتباری مشتریان، بررسی ریسک اعتباری آنها بوده است. در گذشته ریسک اعتباری غالبا با قضاوت شهودی تعیین میگردید که در مقایسه با روشهای آماری و هوش مصنوعی که اخیرا مورد توجه قرار گرفتهاند ازکارایی کمتری برخوردار بوده است. این در حالی است که بکارگیری روشهای آماری، مستلزم توزیع مشخص دادهها میباشد و از طرف دیگر استفاده از روشهای هوش مصنوعی نیز مستلزم محاسبات ...
Abstract: With the globalization of online shopping, deterioration of the ecological environment and the increasing pressure of urban transportation, a novel logistics service mode—joint distribution (JD)—was developed. Selecting the optimal partner combination is important to ensure the joint distribution alliance (JDA) is sustainable and stable, taking into consideration conflicting criteria....
There are usually more requirements than feasible given valuable ones for implementation in order to ensure the delivery of a high value system. Simple prioritization approaches like 110 ranking or MoSCoW lead to numerous ties requiring one to repeat the process for the tied items. In a previous study [1] we analyzed 17 different prioritization frameworks that could be used to perform value-bas...
This paper presents a fuzzy multiple criteria decision making (FMCDM) problem with the Technique for Order Performance by Similarity to Ideal Solution (TOPSIS) based on the new concept of positive and negative ideal solution. Whereas decision making is a process which accuracy of data play major role to select the best alternative, considering decision making problems in fuzzy environments moti...
Increases in populations and in particular in developing countries are placing increased pressure on both natural and agricultural resources. In many cases, especially in semi-arid regions, the pressures are compounded by restricted agricultural lands. Reliable and relevant land evaluation is a requirement for land use policy and decision making to support sustainable rural development. Land ev...
Software is everywhere. However, software is not always trustworthy. Confronting the demand of software trustworthiness evaluation, this paper proposes a novel software trustworthiness evaluation approach based on combination weights (CW) and improved TOPSIS methods. The determination of CW relies on exper gments and mathematical computation together. FAHP method is used to determine the import...
TOPSIS is one of the major techniques in dealing with multiple criteria decision making (MCDM) problems, and Belief Structure (BS) model and Fuzzy BS model have been used successfully for uncertain MCDM with incompleteness, impreciseness or ignorance. In this paper, the TOPSIS method with Fuzzy BS model is proposed to solve Group Belief MCDM problems. Firstly, the Group Belief MCDM problem is s...
The process of multiple criteria decision making (MCDM) is of determining the best choice among all of the probable alternatives. The problem of supplier selection on which decision maker has usually vague and imprecise knowledge is a typical example of multi criteria group decision-making problem. The conventional crisp techniques has not much effective for solving MCDM problems because of imp...
بررسی توزیع خدمات شهری در سالهای گذشته مورد توجه زیاد متخصصان برنامهریزی شهری قرار گرفته است. از آنجا که هدف هر دولتی برقراری عدالت در سطوح مختلف جامعه میباشد، هدف این تحقیق نیز بررسی توزیع خدمات شهری در شهر متوسط اندام مرند در استان آذربایجانشرقی میباشد. روش تحقیق این مقاله توصیفی – تحلیلی میباشد و همچنین از روش کتابخانهای و همچنین آمار سازمانها و شهرداری بمنظور جمعآوری دادههای تحقیق ...
As international corporate activities increase, their staffing involves more strategic concerns. However, foreign assignments have many differences, and dissatisfaction with the host country is a known cause of expatriate failure. From the point of view of an expatriate candidate, the decision of whether to take an expatriate assignment can be regarded as a FMCDM (fuzzy multiple criteria decisi...
