System Dynamics Based Simulation Approach on Corrective Maintenance Cost of Aviation Equipments

This paper first analyzes the causality of the maintenance and support (M&S) cost's generation; then draws the stock and flow diagram, establishes the correlation equation of stock, flow, instrumental variables, constants and determines their initial value; on the basis of the model reasonable, analyzes the model's calculation results, observes the change of the model results by adjusting model's parameters to determine the optimal strategy, provides decision support for decision-makers. Emphatically analyzes the influence of parts’ failure rate and preventive maintenance rate on maintenance costs during the equipment's life circle. The analysis results have verified this paper's simulation method's practicality.
