**1.9 Backlog control and priority system**

Maintenance management effectiveness is having many determining factors in that one of the most promptly used factors is amount of backlog. These backlogs are important to manage the manpower and workload necessities in the organization. In addition, it uses in making the overtime decisions, assigning the jobs and recruitment, subcontracting, etc.

Another type of maintenance allows the forecasting of failures through analysis of the condition of the equipment. The analysis is generally conducted through some form of trending of a parameter such as vibration, temperature, or flow. Predictive maintenance allows equipment to be repaired at times that does not interfere with production schedules. This removes one of the largest factors from the downtime cost. The equipment service level will be very high under this type of

c. **Condition-Based Preventive Maintenance:** it is needed when the equipment is monitored repeatedly. The main aim of the maintenance evaluates and concludes the equipment that is necessity of the repairs and what conditions actions to be performed without suffering a breakdown. Many large and successful companies implemented this type of maintenance through automation techniques like PLCs (Programmable Logic Controllers). Respective signals to find out the failures are produced automatically using automation. However, the initial costs and start-ups are considered as very

#### **1.10 Performance measurement**

Performance measures are necessary and it has been implemented in successful organizations so that measures can be controlled in various manners. Hence, it can be used as powerful tool to measure all the activities before and after the tasks to enhance the productivity of the organizations.

#### **1.11 Maintenance strategy**

Based on views, maintenance strategy includes: Corrective Maintenance (CM), Preventive Maintenance (PM), and Predictive Maintenance (PRM) [12].

#### *1.11.1 Corrective maintenance*

This type of maintenance has been used to recollect the items in satisfactory levels after it has a repair or after degraded below its performance. Planning is also to be considered to maintain the tasks and for logistics which can improve the efficiency of the company. The establishment of the maintenance and logistics requirements is accomplished through analysis of the system's designed-in maintainability and reliability features and attributes, whereas it is most expensive approach to make the maintenance. Service levels should be generally below the levels which can be acceptable. Sometimes, failures happen inappropriate times and hence, interrupt the production system severely. Definitely, maintenances are most expensive because resource planning is not been considered. But, parts need express movement, and the cost is also in effective manner. Overall, the corrective maintenance has been used in successful companies.

#### *1.11.2 Preventive maintenance*

It is "Maintenance carried out at predetermined intervals or according to prescribed criteria and intended to reduce the probability of failure or the degradation of the functioning of an item."

PM is maintenance performed to retain a system in a satisfactory operational condition by inspection, and subsequent repair or replacement, and by scheduled overhaul, lubrication, calibration, etc. Poor maintenance practice will actually degrade the condition of the system. Poorly executed preventive maintenance will result in significantly lower operational reliability, higher maintenance cost, and unnecessary downtime.

Preventive maintenance is any planned maintenance activity that is designed to improve equipment life and avoid any unplanned maintenance activity. All these levels are used to control the small failures before they arise in equipment outage. With this PM, many potential issues can be controlled before they occur.

Preventive maintenance is considered majorly in two factors. Such as, cost of the program and the utilization of the equipment.

Also, preventive maintenance can be characterized as follows:
