The definition of Maintenance is a combination of action carried out to restore in any equipment, to its normal working condition. There are two set of maintenance which is –Proactive and Reactive Maintenance. (1.) On the one hand is –the Predictive Maintenance and Preventive Maintenance which is the proactive maintenance (2.) Then the Corrective Maintenance which is a reactive Maintenance.


Therefore, the four Maintenance philosophy and strategies are;-

(1) Preventive Maintenance – The type of Maintenance carried out regularly before any major break down to restore any equipment back to its normal working condition.
(2.) Predictive Maintenance-carried out before it is actually necessary after a careful examination or inspection of any equipment.-(through diagnostic method).
(3) Corrective Maintenance- the type of maintenance carried out after the break down of any equipment called -rectro-active strategy system of maintenance
(4) Reliability-Centro-Maintenance –the type of maintenance that involved the improvement programme in the cost –effective and technically feasible approach. It also comes to utilize a systematic structured approach based on the consequences of any failure.


THE FOUR (4)-LIKELY CONSEQUENCES OF POOR MAINTENANCE.

(1) –Reduced production Capacity.- This is when the Assets tends to perform under-expected target of which the consequence is down-time.
(2.)- Increase Production cost- This is when the real cost and opportunity cost increases due to asset not performing in its optimal level.
(3)- Low quality Product & services- This is when we have customer dissatisfaction that could result to lost of sales and costumers in the process.
(4)- Safety Hazard- that implies failure leading to injuries and finance and even lost of life in the process.


SOME WAYS TO OVERCOME THESE PROBLEMS

These problems can be partially overcome through Schedule inspections and monitoring programmed to assist in optimizing the planned maintenance intervals.
Through a structure like method called –Checklist- through which consistent information about the actual condition of the equipment is known.
A designed out maintenance method to eliminate high cost due to poor engineering design and maintenance practices or operation of a system outside its design-specification.
