AI Technical Summary
Technical Problem
The uncertainty in the use rate of rental products leads to difficulties in scheduling preventive maintenance timing, affecting the efficiency of use and cost control of rental products.
Method used
By constructing a failure rate function model and usage distribution function based on the usage rate of the rental product, combining preventive maintenance parameters, a preventive maintenance strategy optimization model is established to calculate the optimal preventive maintenance strategy for the rental product.
Benefits of technology
It improves the efficiency of the use of rental products, reduces the lessee's maintenance costs and losses in the event of product failure, thereby minimizing the lessor's costs.

Abstract
The invention belongs to the technical field of preventive maintenance strategy optimization under the condition that the utilization rate of a leased product is uncertain, and particularly relates to a preventive maintenance strategy optimization method and system based on the utilization rate of the leased product, and the preventive maintenance strategy optimization method comprises the following steps: S1, constructing a failure rate function model of the leased product based on the utilization rate; wherein the usage rate is the ratio of the usage amount to the usage duration; constructing a utilization rate distribution function of the leased product; s2, constructing a preventive maintenance strategy optimization model according to the fault rate function model, the utilization rate distribution function and the preventive maintenance parameters; and S3, calculating by using the preventive maintenance strategy optimization model to obtain an optimal preventive maintenance strategy of the leased product. According to the method, the preventive maintenance strategy of the leased product under the condition that the utilization rate is uncertain is optimized, and on the premise of considering the decision of the lessee, the use efficiency of the product is improved, and meanwhile, the cost is reduced.
