Abstract:

In order to solve the problem of increasing the maintenance cost of the contractor by maintaining each single component in isolation during the warranty period, combined with the maintenance status of complex equipment, based on the two-dimensional preventive maintenance cost model of single component, the research object is expanded from single component system to complex equipment including series multi component system with the main quantitative analysis index of warranty cost during the warranty period. Based on the introduction of preventive maintenance benchmark interval and the method of combined maintenance, a two-dimensional preventive combined maintenance cost model of multi-component system is established. Finally, an example is given to verify the feasibility of the method. This strategy can provide a scientific basis and quantitative analysis method for the formulation of multi component system combined maintenance strategy under two-dimensional preventive maintenance service.

Key words: economic dependence, complex equipment, two-dimensional warranty, two-dimensional preventive maintenance, combined maintenance
