Spare demand determination based on simulation

Abstract:

Accurate spare forecast is the basis of effective logistics supporting. An analytic method was put forward according to the reliability and maintenance parameters to determine the spare demand. Based on platform of Exspect and Petri net，a simulation method was used to calculate an example task. The spare demand was determined and different spare support schemes were compared to obtain the optimized value. The effectiveness of this simulation model was demonstrated through a particular case.
