data envelopment analysis (dea) is a managerial powerful tool for assess the performance of decision making units (dmus). nowadays, multi-objective dea models are an attractive technique for evaluation quantity and quality aspects of performance analysis. but these models are in static. in this paper, we want to present a proposed fuzzy dynamic multi-objective dea model in which data are changi...

decision making plays an important role in sport activities and is directly associated with sporting success or failure. on the other hand, one of the key issues in psychology of sports and behavioral sciences is sport orientation. the aim of this study was to investigate the relationship of action and state orientation with decision making behavior of expert female football players. 27 players...

One of the important roles of pharmacists is to continue their contributions to new drug discovery and development. However, it seems to be very difficult to obtain patient satisfaction with new drugs. Because new medicines have both benefit and risk, there should be many systems to maximize the safety and efficacy of the drugs. In clinical trials, the rights, safety and welfare of human subjec...

When travelling in groups, animals frequently have to make decisions on the direction of travel. These decisions can be based on consensus, when all individuals take part in the decision (i.e. democratic decision; social information), or leadership, when one member or a minority of members make the decision (i.e. despotic decision; personal information). Here we investigated whether decision-ma...

in conventional dea models, decision making units (dmus) are generally assumed as a black-box while the performance of decision making sub-units (dmsus) and their importance play crucial roles in  analyzing the performance of systems which have internal processes. the present paper introduces an ideal network which have efficient processes and next purposes a new approach for evaluating importa...

When introducing new technologies, companies are repeatedly faced with choosing between solutions from different providers. Regardless of all the good technical characteristics technology, if it is chosen inappropriately, can prove to be a cost driver instead something that brings added value system. Aware this, we considered selecting real-time location system (RTLS) based on Ultra-wideband te...

In recent years, some methods have been proposed in solving performance evaluation issues by using fuzzy set theory. In this paper, an improvised method for performance evaluation under fuzzy environment is presented. Fuzzy linguistic variables are used throughout the process and the aggregated fuzzy numbers which are based on the standard score concept are employed in aggregating the fuzzy ass...

In this paper, environmental sustainability performance assessment of 27 U.S. and Canada metropoles is addressed. A four-step hierarchical fuzzy multi-criteria decision-making approach is developed. In the first step, the proposed methodology is established by determining the sustainability performance indicators (a total of 16 sustainability indicators are considered), collecting the data and ...
