New Parameter of Maintenance Time and New Development in Maintenance Design Technology

For the requirement of operational readiness in good rate,a new maintenance delay time parameter is proposed,and the models on mean time to repair(MTTR),mean delay time on multi-unit synchronic maintenance and multi-unit maintenance waiting time are built.With the models,the discrepancy of the inadequate maintenance design on multiple units between the operational readiness and the redundancy structure can be resolved and the optimized maintenance design can be enhanced.
