可靠性分析是工程中改进和优化系统的重要依据。结合实际问题，提出由一个主用单元和负荷分担故障率时变的n中取m表决系统构成的多单元系统，存在第I类故障相关关系。通过系统分析，得出主要单元故障率函数，分析系统状态，利用马尔科夫过程原理，建立一个一阶线性微分方程组，通过求解方程得出系统瞬态可用度及可靠度。

In order to improve and optimize the systems of engineering,reliability analysis is proposed. According to the practical problems, a multi-unit system with one dominant unit and numerous secondary units is advanced,in which,the secondary units take form up to a m-out-of-n voting system with load-sharing and time-varying,and the type-I failure interaction is existed between the dominant unit and m-out-of-n voting system. Through researching on the system,failure rate function of dominant unit is derived. Using the properties of Markov process,a first-order linear differential equations is established,after that,the transient availability and reliability of the system can be solved.
