有限制条件的异类元件构成系统的元件维修率分布确定
Determine heterogeneous components maintenance rate distribution in limited conditions
摘要
Abstract
In order to study the maintenance rate of different components in the system,at the same time,considering the influence of work environment factors to the maintenance rate,this paper gave the concept of components maintenance rate distribution.The fault probability distribution in the SFT replaced the failure rate of Markov chain to form the concept.It gave the deducing processes of components repair rate distribution in parallel and series system.The keys of implement maintenance rate distribution calculation were the range of state transition Po,and the ratio of different component failure rate and repair rate,which was needed for the calculation process constraints.With the range of state transition P0 and proportion limit,this paper gave the calculation method and the basis.Analysing a hybrid system,the result illustrates the Po range depend on the system structure and calculate the 0.087 ≤p0 ≤0.625.It has received the maintenance rate distribution of three different components in the system.关键词
