The Evaluation of COAs Based on Stochastic Interval Weighted Sum Method

Abstract:

An important element of military operations is the evaluation of courses of action (COAs) in order to overcome emergency situations. In this kind of decision-making situation, it is important to consider several criteria to evaluate the various COAs, and to compare and rank the COAs according to their ability to meet the selected criteria. It is often necessary to balance the importance of these criteria accordingly to commander’s viewpoints. A new method has been proposed for evaluating the COAs that is based on the possibility calculus known as stochastic interval weighted average operator. The method first presents the attributes and its weights by stochastic interval numbers, so empirical and statistical information, as well as for opinions and judgments made by commanders and analysts, all can be integrated, second, the random numbers of sums of independent variables can be generated by Monte Carlo method, lastly, the comparing and sorting of COAs are realized by random variable Comparison. An example is given to demonstrate the feasibility and practicability of the proposed method.
