An Improved Evaluation Method based on Cloud Models for Situation Consistency within the Battlefield of Joint Operations

摘要

To improve rationality and veracity of situation consistency assessment in battlefield and deal with the conversion from qualitative remark to quantitative evaluation effectively in evaluation, the improved assessment Method of Cloud Gravity Centre (MCGC) in Cloud Theory and Structure Entropy Weight (SEW) calculating index's weight are introduced. By a simple example, the situation consistency of Air Intelligence Picture is evaluated. Each index's entropy formula is revised based on variance in probability theory to increase reliability of MCGC. The indices' weights are considered in each-level indices' calculation for its expected value and entropy to insure this method's rationality. The method of SEW makes sure the weight's calculation simple. The research indicates that the modified MCGC is scientific and feasible in situation consistency assessment in battlefield.
