As the operational time of mechanical equipment increases, the probability of equipment failures rises, and the complexity of spare parts inventory management also grows. Traditional methods of spare parts inventory management often overlook changes in equipment health status, leading to stockpiling or shortages that affect production efficiency. To improve the accuracy and responsiveness of inventory management, this study proposes a tiered management strategy for spare parts inventory based on equipment health status. By integrating health status monitoring data, the strategy categorizes spare parts into different levels and implements differentiated management strategies for each category, optimizing inventory levels and procurement tactics. This approach enables precise management of equipment spare parts, reduces inventory costs, ensures timely equipment maintenance, thereby enhancing corporate production efficiency and resource utilization.
