Evaluation modeling of spare parts scheme under different support systems

Spare parts are one of the most important substances that guarantee the sustainable work of the equipment. For different tasks, spare parts support structure is different. Based on the METRIC theory, the inventory model of two level single layer spare parts under different support system is established. Through an example analysis, it compares the changes of the equipment availability with time under the different parts of the dynamic support system and the fixed support system. The case results are in good agreement with the actual situation.
