Reliability measurement of Complex equipment based on life lost transfer model

In this paper, based on generalized quality loss, we build a new Complex equipment life lost-GERT model for complex equipment reliability issues. Then we design the solution algorithm using the principle of maximum entropy and the effective solution algorithm given complex equipment life lost-GERT and complex equipment the generalized reliability and interval reliability measures parsing algorithm for difficult to determine the characteristics and distribution of the probability of inter-node information. At last, the engine system of some large civil aircraft is taken as the example to illustrate the validity of the algorithm proposed in this paper.
