摘要：

In view of the reality that the ship equipment has a long sea voyage time and is far away from the shore base, and the spare parts are difficult to be supplied in time, this paper systematically studies the mission-oriented calculation of the utilization rate of the ship equipment spare parts. Firstly, the calculation method of the utilization rate of the unit-level spare parts is analyzed, and the utilization rate model of the unit-level spare parts is established. Secondly, based on the above analysis, according to whether the shortage of the spare parts will cause the system shutdown, the spare parts are divided into key units which can cause the system shutdown and non-key units which cannot cause the system shutdown, and the equipment system with complex structure is approximated as a series system. According to the two cases of task success and task failure, the calculation model of the utilization rate of the system-level spare parts during the mission is studied. And the calculation model of the utilization rate of the system-level equipment spare parts during the long sea voyage task is established with the success rate of mission as the restrictive constraint. Case calculation and simulation analysis prove that the proposed model can meet the requirements of engineering application, and can provide theoretical support for the equipment support department to formulate the spare parts allocation scheme of the long sea voyage mission. © 2023 Chinese Institute of Electronics.
