Spare parts support model with different repair time distribution

摘要

Spare parts are one of the important supporting resources of equipment. According to the different distribution of maintenance time in spare parts support model, the model of spare parts support models with exponential distribution and constant distribution are established. According to the maintenance and supply of spare parts, the simulation model is established based on discrete event and Monte Carlo simulation. The equipment availability of different spares support model under different repair probability are calculated and compared. The results show that: when the spare parts repair probability is less than 1, we can use the constant distribution model to replace exponential distribution model, and this can greatly improve the computational efficiency.
