Optimizing the damage detection cycle of the spare parts based on the failure data

In order to prepare for the launch mission, some spare parts for consumption are stored in the spaceport. The spare parts are regularly detected so that all of them can be kept in good condition, but detection may cause some damage. In this paper, the optimization of detection cycle to the spare parts is studied. Firstly, the life model of spare parts is created, which is on the condition of damage detection, in order to estimate the failure rate during the period of storage and the failure probability of the spare parts for each detection. Secondly, the model of optimizing the detection cycle is established so that the detection cycle can be optimized. At last, a numerical example is given and a simulated experiment is designed at the same time. The results show that the method proposed in this paper can be used to calculate the best detection cycle to the spare parts and the availability of the spare parts.
