Abstract

Model selection & evaluation is the key focus and urgent problems to solve in comprehensive argumentation and conceptual design of weapon system, and has great significance for the weapon system to realize function demand, hierarchy management, and decision optimization. Aimed at model selection & evaluation of weapon system, the model selection & evaluation method based on interpretation structure model (ISM) and gray analytic hierarchy process (GAHP) is designed, hierarchical relationship between structure and performance of weapon system is qualitatively described through setting up directed-graph of system structure, and overall evaluation value of design plan is quantitatively represented by determining influence weight between the elements of system and the gray evaluation vector. Combined with evaluation execution procedure, the mathematical model is given, and taking an airborne weapon system as example, Matlab program is compiled, the best plan among the three is selected, and the theoretical basis is provided. Model selection evaluation method of weapon system based on ISM & GAHP has solved the problem from qualitative demand to quantitative decision-making, and with guiding significance for the model selection evaluation of weapon system.

摘要

系统选型评价是武器装备综合论证、方案设计的重点工作内容和亟待解决的关键问题，对武器装备实现功能需求、层次管理和优化决策具有重大意义。针对武器系统选型评价需求，设计了基于解释结构模型(ISM)和灰度层次分析法(GAHP)的武器系统选型评价方法，通过构建系统结构有向图，定性描述了武器系统结构和性能的层次关系，通过确定系统元素间影响权重及其灰色评估向量，定量表征了设计方案的综合评价值；结合评价方法的实施步骤，给出了数学模型，并以某机载武器系统为例，对3种方案进行了择优，同时给出了理论依据；基于ISM和GAHP的武器系统选型评价方法，解决了武器系统从定性需求到定量决策的问题，对武器系统选型评价具有指导意义。
