Did you know that performing maintenance without a planning generates up to 65% of wasted time? Of the 8h of work, only 2,8h are really used. Therefore, Maintenance Planning and Control (PCM) is so relevant in the organization of maintenance management. Maintenance is like an integrated system with objectives, strategies and processes that need to be planned, designed, and controlled using statistics and optimization techniques. Performing Maintenance Planning and Control (PCM) allows decision makers to consider maintenance as a provider of competitive advantage, not a necessary evil. The PCM should be considered as an ally of management.
Maintenance Planning and Control (PCM) is a strategic core of the maintenance industry. He is responsible for aligning the whole process. This, from planning to execution and analysis of the efficiency and quality of the work performed.
PCM includes details such as: The security procedures to carry out the activities; Detailed description of maintenance plans; Resources needed to perform each task such as: labor, spare parts, tools, materials and supplies. The planning phase of PCM is one of the most important. The main goal is to create and manage existing maintenance plans.
Each of the plan types has a particular form of management, execution, and scheduling. However, all converge towards the same goal: to ensure the trust and availability of assets.
Types of PCM
Maintenance Plans are divided into:
Preventive Maintenance Plan
It is performed at predetermined intervals or according to prescribed criteria, in order to reduce the risk of failure or degradation of an equipment’s performance. Maintenance cycles are planned according to the need to remove the service device. The incidence of operational failures is reduced. Within preventive maintenance and taking into account the type or infrastructure of the equipment, the maintenance manager may also have to manage conditional maintenance and predictive maintenance in business. All this, based on the parameters of monitoring and degradation of the operation of an equipment.
Predictive Maintenance Plan
It seeks to know and constantly report the status and operational capacity of the facilities, knowing the values of certain variables, which represent the state and operational capacity. This maintenance is the most technical. It requires advanced technical resources and in moments of strong mathematical, physical and / or technical knowledge in maintenance planning training and it have some maintenance planning courses.
Corrective Maintenance Plan
Maintenance is performed after the detection of a problem and aims to restore normal operating conditions.
This approach is based on the firm conviction that the costs sustained by downtime and repair in the event of failure are less than the investment required for a maintenance program. This strategy can be profitable until catastrophic failures occur.
Conditional Maintenance Plan
It is the maintenance plan based on monitoring the performance of the equipment and controlling the corrective actions taken as a result. The actual condition of the equipment is continuously assessed by the online detection of significant parameters of the working device and its automatic comparison with average values and performance. Maintenance is performed when certain indicators show that the equipment is deteriorating and the probability of failure is increasing. This strategy, in the long run, can drastically reduce maintenance costs. This action minimizes the occurrence of serious failures and optimizes the management of available economic resources.
Risk Maintenance Plan
Maintenance performed integrating the activities of analysis, measurement and periodic testing to standard preventive maintenance. The collected information is visualized in the context of the environmental condition, operation and process of the equipment in the system. The purpose is to perform the asset condition and risk assessment and set the appropriate maintenance program. All equipment that exhibits abnormal values is refurbished or replaced. In this way, it is possible to extend the service life and ensure over time high levels of reliability, safety and efficiency in work places.
