امروزه توسعه سیستمهای کارآمد و اثربخش بهداشت درمان به یکی از نگرانیهای اصلی دولتها تصمیمگیرندگان تبدیل شده است. تأمین بهموقع دارو کارایی سیستم موجودی توزیع، نقشی حیاتی در زنجیره بیمارستانی دارند برای افزایش این فعالیتها، فرآیند تصمیمگیری مناسب مدیریت ضروری نظر میرسد. پژوهش یک مدل دوهدفه بهصورت برنامهریزی خطی عدد صحیح مختلط جریان اطلاعات ارائه اهداف حداقلکردن هزینههای خرید، نگهداری، ...
abstract regarding the imprecise or fuzzy data on the agriculture activities, applying models based on fuzzy data may be useful. in line with this condition this study tries to compare the ability of possiblistic programming approach in developing optimal solution with fuzzy and deterministic programming. to get this objective a data set obtained from 90 farmers of kohgilooye region, gathered i...
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.
In this paper, we deal with a two-person zero-sum games with fuzzy payoffs and fuzzy goals. The aim of the paper is to explain new concepts of solutions for a two-person zero-sum games with fuzzy payoffs and fuzzy goals. We assume that each player has a fuzzy goal for each of the payoffs. A degree of attainment of the fuzzy goal is defined and the max-min strategy with respect to the degree of ...
Tri-level optimization problems are optimization problems with three nested hierarchical structures, where in most cases conflicting objectives are set at each level of hierarchy. Such problems are common in management, engineering designs and in decision making situations in general, and are known to be strongly NP-hard. Existing solution methods lack universality in solving these types of pro...
location selection is one of the most important activities in establishment of bank branches. choosing a suitable location have a direct impact on the performance of banks and also facilitating the achievement of other objectives. there are a lot of influential factors on the location selection which are complicated and therefore the traditional methods cannot be used. so we need to have a suit...
The multiobjective problem with fuzzy goals (which may also represent fuzzy right hand sides of the constraints) is formulated as a fuzzy goal programming problem. A new approach and a new solution method are proposed.
