For long-wait-short-run equipment, it is in the standby state with very short operating time during its lifetime. The performance degradation of this equipment depends on not only the accumulative operating time, but also the accumulative non-operating time. In this paper, the reliability model of the long-wait-short-run equipment is established based on Gamma process in which both the accumulative...
To investigate the optimal policy of continuously deteriorating system with economical dependence, a kind of improved opportunistic maintenance policy is presented in this paper. This system is composed of two kinds of units, which are subjected to the deterioration failure described by Gamma process and the Poisson failure respectively. The maintenance mode and corresponding control threshold are...
Long-stop-short-run(LSSR) system is a kind of system that is longtime non-working and short time operating. It is important to study the reliability of LSSR system in some safety critical areas. There exist manifold failure mechanisms in the LSSR system. In this paper, a competing risk model is proposed to describe the reliability of the LSSR system. LSSR system presents two main kinds of failure...
Degradation data can provide with useful information about the reliability assessment for highly reliable products. In this paper, a method based on performance degradation data is proposed to assess reliability of high reliable long life time products. The degradation process can be described as a gamma process, and then reliability can be assessed based on analysis on failure physical mechanism...
