The necessity of implementing a Preventive Maintenance strategy to minimize the occurrence of Emergency Maintenance situations.

In machine-oriented production units, as well as for machinery sales dealerships responsible for after-sales service commitments, following an efficient strategy is essential to prevent rapid wear and tear of machinery and to maximize operational efficiency.
PM (Preventive Maintenance) refers to maintenance and repair activities that are planned and predictive in nature. The implementation of a PM system—which includes remote services—offers several benefits, such as extending the lifespan of machinery, reducing emergency downtimes, and improving workplace safety.
EM (Emergency Maintenance) refers to urgent maintenance and repair activities carried out when an unexpected and unplanned machinery failure occurs, requiring an immediate and swift response to restore functionality.
In general, in units where the PM system is properly implemented, unexpected breakdowns occur significantly less frequently.
Inventory control systems for spare parts, if supported by a reliable PM (Preventive Maintenance) system, are organized based on the periodic service schedules recommended by the machine manufacturer, and according to either the machine’s operating hours or the amount of production completed by the machine.
Typically, to anticipate potential machine failures from the outset of purchase and installation, the selling company provides a set of essential spare parts based on its prior experience. Over time, the maintenance unit will procure additional necessary spare parts based on its historical experience and familiarity with the machine's vulnerable components.
It should be noted that scientifically planning the quantitative and qualitative maintenance of spare parts can prevent unrealistic expectations, low efficiency, and the costly consequences of production downtime. However, maintaining optimal inventory levels is equally essential — both to avoid excessive financial burden and to ensure the availability of required parts whenever needed. This highlights the necessity of effective inventory control planning.
Regarding spare parts inventory control planning, it is necessary to study the conditions and characteristics of each unit separately.
The opinions of colleagues, especially in the specialized fields of production planning, maintenance, and spare parts inventory management, can complement and enrich this discussion.
