Abstract:

In considering many faculty factors,faculty model is not single,and component is not being repaired “as good as new”.A multi-state n-1/n(G) system without being repaired “as good as new” is studied.It is assumed that the working time of the components in the system is exponentially.By using the approach of supplementary variables and method of generalized Markov process,the Laplace transform expression of availability and reliability of the system are derived and the MTTFF is obtained.Finally a linear consecutive-2-out-of-3(G) system is taken as an example to illustrate the practical value of the gained conclusion.

Key words: multi-state;without being repaired “as good as new”;reliability;markov process
