Abstract: To improve effective operation rate of the manufacturing equipment and reduce the downtime, by taking the complex system as study object and considering integral influences of spare parts and repair equipments, a quantitative model of failure outage rate was established based on the configuration quantities of maintenance resources. Then, the optimized configuration was performed. According to hierarchy of the system, system failure outage rate model was established by two steps. Optimization model for the configuration quantities of the spare parts and repair equipments was proposed with constraints on failure outage rate, and was solved by using marginal analysis algorithm. Finally, an example was provided to verify the validity of the models.
