Title    Wave Analysis under general probability distribution  of instantaneous availability
Abstract
Availability of equipment is an important parameter of well describing equipment Operational Readiness and continuity of mission. In piratical using, equipment availability parameters can be generally pided into steady-state availability parameters and instantaneous availability parameters. For a long time, the research and application of steady-state availability has brought wide attention. However, with equipment’s function being more and more complicated, the equipment availability presents a series of fluctuation phenomenon in the using process. Obviously, these phenomenon can be neither explained nor further studied via traditional methodology of steady-state availability.

Aiming at the above problems, the main works are as follows.
First, this dissertation introduces the problems of the equipment instantaneous availability modeling.
Then, this dissertation introduces the problems of the wave of the equipment instantaneous availability. Some simulations and analysis under truncated discrete Weibull distributions are given.
Finally, based on the proposed discrete-time instantaneous availability model, some numerical analysis is carried out using the Particle Swarm Optimization Algorithm.
