        < p>In this paper, first the DEA-RA (integration of DEA with Ratio Analysis) output and input oriented is proposed. Then, by using the fully fuzzy problem and the problem that only the parameters are fuzzy, the DEA-RA joint model has been proposed. Therefore the lexicographic approach and the α-cut approach have been used for these two types of the problems and evaluation of research projects. DEA-RA models behave similarly to DEA models. In this study, the input and output parameters are not ratio, but if the input to output ratios and vice versa are defined, DEA-RA models can also be a criterion for calculating the efficiency and evaluation of units. تفاصيل المقالة

        In this research, the multi-objective project management decision problem with fuzzy goals and fuzzy constraints are considered. We constitute α-cut approach and two various fuzzy goal programming solution methods for solving the Multi-Objective Project Management (MOPM) decision problem under fuzzy environments. The Interactive fuzzy multi-objective linear programming (i-FMOLP) and Weighted Additive approaches are proposed for solving multi-objective PM decision problem where fuzzy information are demonstrated by using linear membership functions (LMF). The proposed approaches effort contemporarily to minimize the total project costs, total completion time and total crashing costs and the several constraints such as the time between events i and j, the crashing time for activity (i,j) and the total budget capital. The weight of criteria for each objective function base on project DM preference degree computed with Fuzzy AHP technique. The performance analysis calculated with a set of distance metric for i-FMOLP and Weighted Additive solution methods that represent uncertainty goals and constraints in PM decision problem with ideal solution in an industrial case study is compared. تفاصيل المقالة
