基于设计参数综合评价决策的维修性设计方案优选方法

摘要

Aiming at evaluation and selection of maintainability design schemes, a new preferred selection method based on integrative evaluation of design factors was proposed. Considering the uncertainty and fuzziness of design factors' evaluation, linguistic assessment values of maintainability design factors were quantified on the basis of the set pair analysis theory, and evaluation and decision-making model was established by introducing the weighting method based on AHP into similarity scale of schemes. Finally, preferred selection for design schemes of some manned spacecraft power system was taken as an example to illustrate the application and effectiveness of this method.%针对维修性设计方案的评估优选问题进行分析,给出一种改进的设计参数综合评价优选方法.考虑到维修性设计因素评价的不确定性和模糊性的特点,采用集对分析理论对维修性设计因素的模糊语言值评价进行处理,并将层次赋权方法引入方案贴近度评估决策模型,以提高方案优选的可信性.最后以某航天器电源系统的维修性设计方案优选为例说明了该方法的应用及有效性.
