摘　　要：针对国内外研究热点和难点——装备可靠性、维修性、保障性(reliability,maintainability and sup-portability,RMS)一体化设计,提出其中的瓶颈是RMS之间的强耦合机制及其设计知识流动控制问题。为此,分析、论证并提出了一种装备RMS一体化设计的创新研究方案:首先采用具有严格数学基础的图论方法———分层加权有向图进行RMS建模,以系统、科学、客观地刻画RMS强耦合关系;引入图书情报、管理工程中的知识流理论以实现RMS耦合设计知识的流动控制;采用模糊粗糙集理论以解决RMS不确定知识问题。可为装备RMS一体化设计理论的发展提供一种创新的、可行的参考思路。The integrated design of reliability,maintainability and supportability（RMS） is one of key technical challenges and research hot spots in the engineering and academic field at home and abroad.Although achievements have been attained in the individual engineering of reliability,maintainability and supportability,the problem of strong-coupling between RMS and control of design knowledge has not been resolved up to now.The strong-coupling between RMS characteristic parameters and their logic relations results in the intersectant design processes and knowledge of RMS,which affects the real integration of RMS data and design tools.In this paper one research solution of RMS integrated design is presented.Firstly,the layered weighted digraphs method is introduced to model and decouple this strong-coupling relationship scientifically and impersonally because the graph theory has the strict foundation of mathematics.Then,the knowledge flow theory of library and management science is introduced to lead the scientific flow of design knowledge between the RMS coupling fields.Finally,the fuzzy rough sets theory is adopted to study the problems of uncertain knowledge and case data missing under coupling RMS case.This research solution can provide one new idea and solution for the development of integrated design theory of RMS.
