the aim of this research is consider the importance of decision maker level of analysis in the study of foreign policy. this capability created by the regard to the role of man in foreign policy and international relations theories. however, the main research question is whether the decision maker level of analysis will be the theoretical support for the analysis of foreign policy and what are ...

Data Envelopment Analysis (DEA) is a mathematical programming-based approach for evaluates the relative efficiency of a set of DMUs (Decision Making Units). The relative efficiency of a DMU is the result of comparing the inputs and outputs of the DMU and those of other DMUs in the PPS (Production Possibility Set). Also, in Data Envelopment Analysis various models have been developed in order to...

the ways of placing decision making units (dmus) in certain clusters are found as a subject in statistics, these ways usually are heuristic. the proposed clustering approach in this article considers preferences of dmus. this study applies data envelopment analysis (dea) dmus are clustered by solving multi-objective linear problem (molp) and by considering preferences of each dmu at production ...

Belief networks and influence diagrams use directed graphs to represent models for probabilistic reasoning and decision making under uncertainty. They have proven to be effective at facilitating communication with decision makers and with computers. Many of the important relationships among uncertainties, decisions, and values can be captured in the structure of these diagrams, explicitly revea...
