Construction method and system of system effectiveness evaluation index system based on correlation analysis

Abstract

The invention provides a system effectiveness evaluation index system construction method and system based on association analysis, comprising the steps of primary selection of evaluation index, acquisition of evaluation index sample, extraction of association evaluation index and establishment of evaluation index system. The invention can mine the correlation relationship between the equipment-level performance / efficiency index and the system-level efficiency index. The dynamic discrete method based on clustering analysis is used to realize the discretization of the consequent parts of association analysis, and the result can reflect the relationship between the system-level efficiency index and the minimum support degree, which is more accurate than the static discrete method based on equal depth, equal width and so on. It solves the problem that it is difficult to establish a scientific hierarchical index system by traditional methods because of the deep hinge and serious index coupling among the equipment systems, and provides a new idea and method for the index system construction of other complex problems.

Description

Technical field [0001] The invention relates to the field of modeling and simulation, and in particular to a method and system for constructing a system effectiveness evaluation index system based on correlation analysis. Background technique [0002] Multi-index comprehensive evaluation based on simulation data is a key technology for weapon equipment combat effectiveness evaluation, which relies on the establishment of a hierarchical index system that is independent of each other. [0003] In traditional combat effectiveness evaluation with weapon systems as the object, weapon systems generally have a series of tactical and technical performance parameters that characterize various characteristics. They involve multiple aspects of weapon equipment, combat missions, and environment. The effectiveness of the system is the above The combination of various parameters, so the effectiveness evaluation index system of weapon systems is often composed of multiple levels and multiple type...

Problems solved by technology

However, system confrontation is a typical complex giant system problem. There are many factors that affect the outcome of the confrontation, including equipment technology factors, combat (command) factors, human behavior (rule) factors, battlefield environment factors, etc., and there are mutual Many cross-effects make it difficult to use a hierarchical index system for secondary modeling. Taking the air defense equipment system as an example, according to the idea of ​​hierarchical decomposition, according to its system composition, it can be divided into three types: search radar, tracking radar and interception weapons. Each type of weapon system can be decomposed according to its performance indicators, and finally a hierarchical index system is established. However, the three types of weapon systems will be affected by each other in the actual combat process. For example, the performance indicators of search radars may affect From the final effectiveness of tracking radar and interception weapons, the systems are deeply hinged and the indicators are seriously coupled. Therefore, how to take into account the interaction of various factors when constructing the indicator system is a key technology for the effectiveness evaluation of weapon equipment systems
