Assume that the system after repair is not "as good as new",by using the geometric process, we examine the long run average costs under pro rata warranty policy for both consumer and manufacturer, and the long run average costs under free warranty policy for manufacturers, The explicit expression of the costs can be found.

Extension analysis method of maintenance strategy of engine cylinder body production line;

Synchronization maintenance strategy analysis of engine cylinder body production line;

Optimal Maintenance Strategy for the Repairable System Consisting of One Component Based on Geometric Process;

How to select equipment maintenance strategy for hydropower station

There are many bad points in maintaining generator set,so the state maintenance strategy based on Markov chain state estimative model is presented.

maintenance strategy, maintenance arrangement, and maintenance implementation.

Operational availability model for repairable system under(m,N_G) maintenance policy;

In three kinds of maintenance policy such as maintenance after the event, regular maintenance and state maintenance, maintenance policy should be selected reasonably so as to reduce operation expenditure and increase production benefit.

A maintenance policy matching with to armor chariot s service time is presented in this paper.

Based on PSO algorithm,a new repair strategy is provided to handle the constraints and make sure the particles to satisfy the constraints.

A penalty based effective repair strategy is also proposed to repair the infeasible chromosome, making the solutions more practical.

Let the combination of penalty function method and renovation strategy be applied to the optimal genetic algorithm with nonlinear constraint,thus let the constrained optimal problem be converged in an overall optimization under the coordinative effect of penalty function and renovation operator.
