In recent two decades, countries focused on minimum extraction of fossil fuels and utilized the renewable energies based on countries' policies and the environmental considerations. Thus, choosing the best renewable energy alternative is a significant role to investment on them. Among the classical decision approaches that have used in the literature, the hesitant fuzzy sets (HFSs) theory is ap...

in developing countries, the domination of peripheral and dependent capitalism relations and the lack of appropriate structures and channels of attracting, this system have caused some kind of spatial-anatomic unbalances that has resulted in the appearance of single cities with national and regional prevalence. this situation is the main reason for small, medium and intermediate cities to lose ...

Further researching and development in the field of health and safety at work should be looking beyond traditional principles, on a quite new, innovative and contemporary approach. Changing the approach is natural, obvious and necessary regarding frequent technology improvement on all fields, emerging industrial facilities, big social, economical and demographic changes, as well as changes of w...

Establishing innovation alliance has now become a very important and indispensable way for achieving the mission of research and development (R&D) of national mega projects in China. As an important component for constructing the collaborative partnership system, an appropriate approach of partner selection should be able to evaluate the performance of candidates objectively. Innovation allianc...

‎in this paper, we present a two-stage model for ranking of decision making units (dmus) using interval analytic hierarchy process (ahp). since the efficiency score of unity is assigned to the efficient units, we evaluate the efficiency of each dmu by basic dea models and calculate the weights of the criteria using proposed model. in the first stage, the proposed model evaluates decision making...

Sistan region is one of the most important agricultural areas in the province of Sistan and Baluchistan. Therefore, given the heterogeneity in agriculture and recognizing these differences, the aim of this study was to obtain the level of development of agriculture in the Sistan region. To obtain this purpose two Fuzzy Analytical Hierarchy Process (FAHP) and the numerical taxonomy was used in a...

Moved by the need increased for modeling of the fuzzy data, the success of the systems of exact generation of summary of data, we propose in this paper, a new approach of generation of summary from fuzzy data called “FuzzySaintEtiQ”. This approach is an extension of the SaintEtiQ model to support the fuzzy data. It presents the following optimizations such as 1) the minimization of the expert r...

Obesity has been linked to several heart diseases .Unfortunately, Malaysian today are the most overweight or obese people among Asian nations. That is, half of population is overweight. These serious social consequences. Therefore, specific and actions needed reduce eliminate this threat. The rapid increase in obesity rates directed link with factors such as low physical activities, ease transp...

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 alternativ...
