| Abstract: | The total time on test （TTT） is well-known due to its striking applications to dif- ferent areas of science. On the basis of the strategy about age replacement, a multi-objective optimization model of preventive maintenance cycle is constructed with two indexes, average expected cost and average availability of complex compound systems. The emphasis is that the multi-objective optimization model is solved accurately by means of TTT transformation function, then the preventive cycle of compound systems is determined. Some numerical ex- amples are also included to illustrate the decision-making process and to verify its correct- ness and effectiveness. |
