性能评估方法能够解决试验法无法评估定性指标,以及试验难以开展时无法评估性能的问题,已成为支撑各类军民装备现代化的重要技术手段.然而,性能评估方法的指标体系,无量纲化方法及权重方法均存在不足,难以满足精确性的要求.对于指标具有模糊性和不可公度性,且包含多个指标,指标间具有多层次关系的系统而言,例如,惯性组合导航系统,性能评估方法精确性尤为重要.本文梳理了惯性组合导航系统性能评估方法研究进展.首先,介绍了惯性组合导航系统性能评估方法概述,包括性能评估方法概念分析,惯性组合导航系统特殊性讨论及惯性组合导航系统与性能评估方法关系分析.其次,分析了惯性组合导航系统指标体系,无量纲化方法,组合权重方法及评估方法等内容.最后,阐述惯性组合导航系统性能评估方法存在的问题及未来研究方向.

The performance evaluation method can solve the problem that test methods cannot evaluate qualitative indexes, and cannot evaluate performance when the test is difficult to carry out, and has become an important technical means to support the modernization of various military and civilian equipments. However, three parts of performance evaluation method are insufficient to meet the accuracy requirements, which are the index system, the dimensionless method and the weight method. The accuracy of performance evaluation method is particularly important to the system with those characteristics, where the indexes are fuzzy and incommensurable, multiple indexes and multi-level relationship between indexes, for example, inertial integrated navigation system. This paper reviews the perspectives on performance evaluation methods of inertial integrated navigation system. Firstly, the survey of the performance evaluation methods of inertial integrated navigation system is introduced, including the analysis of the concept of performance evaluation method, the discussion of the particularity of inertial integrated navigation system and the analysis of the relationship between inertial integrated navigation system and performance evaluation method. Secondly, the index system of inertial integrated navigation system, the dimensionless method, combination weight method and evaluation method are analyzed. Finally, the problems and the future research directions of performance evaluation methods for inertial integrated navigation system are discussed.
