Abstract
The focus of the study is empirical investigation of maintenance performance of a fast growing independent lubricant blending company in Nigeria. The study was designed primarily to determine whether or not the company has met its maintenance performance targets. Nominal Group Technique (NGT) was used in composing the overall criteria on which maintenance activities of the company were evaluated. The criteria were manpower utilization, plant and equipment performance, amount of services provided and degree of planning. These criteria were assessed using the following performance ratios: equipment availability, cost of spares and supplies, maintenance to production, equipment shut - down intensity, emergency shut - down intensity, and break - down workload. The study revealed that the company was able to operate fairly within the targeted performance ratios set by the company.
Highlights
Maintenance is defined as a combination of actions carried out to retain an item or restore it to an acceptable standard
The summaries of results of the findings of the performance ratios measured are presented in tables 1 -6 Table 1 shows Equipment availability Ratios and percentages of performance target ratios achieved by the company
The below target ratio achieved in 2001 was a result of frequent breakdown caused by mal - operations of some operators on the job training
Summary
Maintenance is defined as a combination of actions carried out to retain an item or restore it to an acceptable standard This standard includes safety, reliability, and quality of output. Other factors which make effective maintenance system to be very important include the needs for increased production level, increased machine utilization and market competition. If down - time can be minimized, the company stands to improve upon output and revenue, reduce production cost, and improving profit This presupposes that other factors of production are available and that company can sell all that she produces. Due to absence of an effective maintenance system, the down - time increases more than what has been planned, the level of activity will reduce This will result to loss of the budgeted profit. The aim of effective maintenance system is to achieve increased plant availability through better management at low cost relative to increased profit
