摘要：This paper is about a research of the relationship between equipment’s reliability, maintainability, supportability and operational availability. It investigates the influencing factors of operational availability, analyzes the maintenance strategies of equipment and specifies distribution types. Based on these findings and Markow process, it then deduces computational model of operational availability. It also defines reliability, maintainability, supportability and other constraint condition and establishes optimizing equations to find feasible solution and optimal solution. At last, it tests correctness and feasibility of established model by case study. After knowing the requirement of operational availability and operational method provided here to define corresponding level of reliability, maintainability, supportability, it transforms operational-using requirement to technical design requirement in support for further research.
