A methodology for the development of PM using the modern approaches of FMEA, root-cause analysis, and fault-tree analysis is presented. Applying PM leads to a cost reduction in maintenance and less overall energy expenditure. Implementation of PM is preferable to the present reactive maintenance procedures (still prevalent in Nigeria).
نتیجه گیری انگلیسی
As unit fossil-fuel costs rise, effective maintenance procedures have become more important in industry in order to reduce energy expenditure and so raise profits. Maintenance efficiency can affect plant availability, costs, business effectiveness and risk, safety, environmental integrity, energy efficiency, product quality and customer service. Because of the complexity of current equipment, repairing and restoration are more difficult and special multi-skill new tools and techniques are needed. Also downtime becomes more apparent and embarrassing: so in a bid to find ways of preventing failure, the concept of PM resulted. Also, as maintenance costs have risen sharply relative to other operating costs, maintenance planning and control systems have attracted far greater interest. Focus is not only concentrated on availability, but also on the related concept of reliability. Improved maintenance procedures such as RCM, TPM, RCFA, and FMEA have been applied to achieve maintenance objectives: the focus is now shifting to highlight those aspects where the inherent design of the system yields probabilities of failure that are unacceptable and so provide some guidance and motivation for improving the effectiveness of the system. The challenges facing maintenance managers today are not in finding methodologies and approaches to apply, but in understanding how they coalesce with one another. The approach has to be to internalize best practice within the organization, and simply become the universally accepted as the ‘‘way we do things around here’’. PM activities are primarily condition-based. The condition of a component measured when the equipment is in operation, should govern its planned and scheduled corrective maintenance (CM). A standard CMprocedure should be developed and documented. This should define the need for CM as part of PM.
