Abstract

The invention provides an optimization method for the periodic preventive maintenance strategy of a repairable degraded system. The reliability model of the repairable degraded system under the cumulative Poisson shock is classified, a suitable reliability model is selected according to the situation and simplified, and the It is applied to the preventive maintenance strategy optimization model as a constraint condition, and a more practical preventive maintenance strategy optimization model is obtained. The invention comprehensively considers the system maintenance cost and the probability that the system is in a normal state at any time, and determines the optimal preventive maintenance period and the system update period under the premise of satisfying the reliability index. It avoids the loss of human and material resources caused by excessive maintenance, and also avoids inconvenience and economic losses caused by untimely maintenance, and obtains maximum benefits for the company in system maintenance. It can also guide enterprises to formulate reasonable equipment maintenance strategies and reduce production costs.

Description

technical field [0001] The invention relates to the field of production management, more specifically, to an optimization method for a periodic preventive maintenance strategy of a repairable degraded system under cumulative Poisson shocks. Background technique [0002] The scale of modern enterprise equipment is increasing day by day, the equipment is increasingly complex, sophisticated and multi-functional, and the maintenance cost of equipment is increasing year by year. The equipment maintenance of the production and manufacturing system has an important impact on the production operation and product manufacturing cost of the enterprise, and has become a decisive factor for the enterprise economy. One of the key factors of effectiveness and market competitiveness. The prerequisite for the effective realization of the production plan of the enterprise is to ensure the efficient and reliable operation of the production system equipment. Most of the systems in actual engine...
