外文摘要：In order to solve the problem of high operating cost of maintenance of enterprise caused by unreasonable number of maintenance personnel， using queuing theory to establish the maintenance queuing model of equipment。 The Semi-Markov analysis method is used to calculate the one-step state transition probability of the maintenance system。 The indexes such as stationary distribution and average queue length are obtained。 The problem of the number of maintenance personnel is transformed into the setting problem of the optimal number of maintenance service stations， and based on the marginal analysis method， the scheme of maintenance personnel allocation is obtained to minimize the total loss cost of the enterprise。 Through the collection and analysis of the fault data related to a power plant in the enterprise， the optimal maintenance personnel quantity scheme of the enterprise is obtained， which can ensure the lowest unit time operation cost of the enterprise under this scheme。
