در روش fuzzy ahp topsis ابتدا ماتریس مقایسات زوجی تشکیل و وزن معیارها با روش های مختلفی تعیین شد. پس از تشکیل ماتریس تصمیم و بی مقیاس سازی با نورم، ماتریس تصمیم بی مقیاس شده وزن دار به دست آمد. سپس، حل ایده آل و ضدایده آل از ماتریس وزن دار همراه با فاصله از ایده‎ آل و ضد ایده آل ها تعیین شد. تمامی این مراحل را با اعداد فازی نیز انجام شد که درنهایت نتیجه هر دو روش انتخاب گزینه شماره دو بود که به...

In practice, due to the lack of information, imprecise variables which come from experts’ empirical data usually appear. In order to deal with these imprecise variables, uncertainty theory is proposed and has been proved to be an efficient method. This paper introduces uncertainty theory into travelling salesman problem (TSP), in which the link travel times are assumed to be uncertain variables...

The aim of this study was to develop an optimal sustainable forest plantation based on goal programming and Analytic Hierarchy Process (AHP) methods. This study was carried out in Guilan province, north of Iran. First of all, the ecological capability of the study area for plantation establishment/maintenance was evaluated based on multi-factor method and specific ecological Makhdoum Model by ...

Cross efficiency evaluation was developed as an extension of DEA. But the traditional DEA models usually have alternative optimal solutions and, as a result, cross efficiency scores may not be unique. It is recommended that without changing the DEA efficiency scores, the secondary goal should be introduced for optimization of the inputs/outputs weights.  Several reports evaluated the perfo...

A theorem was recently introduced to establish a relationship betweengoal programming and fuzzy programming for vectormaximum problems.In this short note it is shown that the relationship does not exist underall circumstances. The necessary correction is proposed.
