Abstract    Decision making is an important issue in business and project management that assists finding the optimal alternative from a number of feasible alternatives. Decision making requires adequate consideration of uncertainty in projects. In this paper, in order to address uncertainty of project environments, interval type-2 fuzzy sets (IT2FSs) are used. In other words, the rating of each alternative and weight of each criterion are expressed by IT2FSs. Moreover, for obtaining weights of criteria, interval type-2 fuzzy analytic hierarchy process (AHP) method is employed. In addition, a new enhanced model of multi-objective optimization on the basis of simple ratio analysis (MOOSRA) method is developed with IT2F-relative preference relation. Finally, to illustrate applicability of the introduced approach, an existing application from literature is adopted and solved.


Keywords    Project critical path problem, Relative preference relation, Interval type-2 fuzzy sets (IT2FSs), MOOSRA method


چکیده    تصمیم‏گیری یک مساله مهم در کسب و کار و مدیریت پروژه است که به پیدا کردن آلترناتیو بهینه از بین آلترناتیوهای شدنی کمک می‏کند. تصمیم‏گیری نیاز به توجه کافی به عدم قطعیت در پروژه ها دارد. در این مقاله، به منظور مواجهه با عدم قطعیت‏های موجود در پروژه، مجموعه‏های فازی نوع 2 بازه‏ای استفاده می‏شود. به عبارت دیگر ارزیابی آلترناتیوها و وزن هر معیار به صورت اعداد فازی نوع 2 بازه‏‏ای بیان می‏شود. علاوه بر این، برای به دست آوردن وزن معیارها از روش وزن دهی فازی نوع 2 بازه‏ای AHP استفاده می‏شود. به علاوه، یک مدل ترکیبی از روش MOOSRA به همراه ارتباط اولویت نسبی فازی نوع 2 بازه‏ای توسعه داده می‏شود. در انتها برای نشان دادن قابلیت روش معرفی شده یک مثال کاربردی موجود در مرور ادبیات حل می‏شود.
