in this research priority of gorgan’s sub- watershed were done after normalizing the indicators using gis software. the multi-attribute decision-making methods including electre, topsis and saw were used in this study. ahp was applied in order to weighting the indicators in expert choice software. first, priority the sub-watershed were done by electre, topsis and saw using the excel. each metho...
در این تحقیق به مقایسه تحلیلی و عددی آبشار جریان برگشتی مدل R با آبشارهای Q QI سیستمهای چندجزیی پایدار پرداخته میشود. راستا برای اولین بار کدهای جهت طراحی منظور کد نرمافزار متلب نوشته شدهاند. نتایج نشان میدهد که دو جزء 1k 2k از خوراک Nc جزء، تعداد معدودی قابل تعریف است همگی حالات خاصی میباشد. همچنین یافتهها مجموع مقدار برش جزیی همیشه برابر یک است. طریق داده میشود صورتی میانگین ...
In this paper, the evaluation of customers’satisfaction is investigated by using group decision making method under uncertainty. Here, we have used the Zadeh’s fuzzy concept to model and measure the satisfaction. For this purpose, we have firstly applied the Delphi method with fuzzy Likert scales. Then, the fuzzy ELECTRE technique was used in order to ordering the index and questionnaires. For ...
Society’s attitude toward seismic risk, in the last few years, has evolved from fatalistic to proactive. This paper presents an approach in the area of seismic risk management. The objective is to implement a methodology in a seismic prone area in an earthquake risk management framework, based on the case study of the island of Lefkada. A tool to assist in the selection of an intervention proac...
An outsourcing contract problem has been analyzed. This is a typical problem when dealing with outsourcing vendor selection. For each alternative of an outsourcing contract there is an evaluation of both cost and quality of service. The latter may include probabilistic delivery time and confidence in quality commitment. The decision-maker takes into account multicriteria evaluation through ELEC...
We propose a generalized approach to the already existing crisp methods to solve the fuzzy multiattribute decision making problem. Specifically we deal with four methods, namely Simple Additive Weighting, Linear Assignment, TOPSIS and ELECTRE, where fuzzy numbers are used to represent the ratings of the alternatives and relative weights of the attributes. Through the use of fuzzy mathematics we...
In multi criteria Decision Making, the decision maker wants to find the best alternative among a set of alternatives in order to satisfy a set of criteria. Traditionally, decision making models are based on crisp data. The shortcoming of these data in capturing the reality and lack of information persuaded researchers to develop decision making methods with uncertain data. In this paper, the EL...
An e-learning architecture selection has been analyzed. This is a typical problem when dealing with e-learning system selection. For each alternative of an e-learning architecture there is an evaluation of both cost and quality of service. The latter may include probabilistic delivery time and confidence in quality commitment. The decision-maker takes into account multi-criteria evaluation thro...
