Optimization of Leased Equipment Maintenance Strategy Considering Maintenance Time Limit

Abstract

: Aiming at the maintenance problem of leased equipment with limited maintenance time, two maintenance strategy models of full refund and proportional refund are proposed. From the perspective of the lessor, the model comprehensively considers factors such as minor repair costs, failure penalty costs, repair time limits and refunds during the rental period, and establishes a full refund with the goal of minimizing the total cost rate expected by the lessor maintenance and proportional refund maintenance are two strategic models, and the relevant theoretical methods for model optimization are given. Numerical analysis verifies the validity and feasibility of the model. The strategy model can provide theoretical support for the lessor to make equipment maintenance decisions.
