%X In the paper, the stochastic process of the failure number is studied in following the line of modelling the dynamic equation for the failure number on the basis of the distribution of the failure time. A mathematical programming model is further proposed by minimzing the total cost for the replacement cycle. An example is used to illustrate its application of the approach.
