DEVELOPMENT OF RELIABILITY-BASED MAINTENANCE MANUAL FOR CRAFTSMEN TRAINING ON INJECTION STATIONS MAINTENANCE IN ABUJA ELECTRICITY DISTRIBUTION COMPANY

Abstract

This study developed a Reliability-Based Maintenance Manual for Training of Craftsmen on sufficient maintenance of Injection stations of Abuja Electricity Distribution Company. One objective was used while one research question and one hypothesis guided the study The research design adopted for the study was Survey design employing Research and Development (R&D) that was categories into three phases thus: Needs Assessment, Development of the Manual and Validation of the Manual. The population of the study was 224 which comprised of 32 Engineers, 64 Technologists and 128 Technicians. The entire population was studied. The instruments that were used for the collection of data included, Need Analysis Questionnaire (NAQ), Reliability-Based Maintenance Manual Content Questionnaire (RBMMCQ), and Reliability-based Maintenance Manual Validation questionnaire (RBMMVQ). The RBMMCQ was validated by five experts. The need analysis result indicated 100% acceptance for the need to develop the manual for Abuja electricity distribution company (AEDC). The Reliability of the instrument was 0.75 determined by using Cronbach alpha statistic. The instrument was administered to the respondents by six research assistants who administered and retrieved the questionnaire after responding to them; there was a 100% return rate. The data collected were analyzed using Mean and Standard Deviation through the use of SPSS Statistic version 23 to answer the research questions while ANOVA Statistic was used to test the null hypotheses at 0.05 level of significance. The findings of the study included among others that the Reliability-based Maintenance Manual is highly needed to replace the run-to-failure maintenance approach in AEDC. The hypothesis results in a significant difference hence Duncan multiple range test was employed to detect the point of significant difference. Based on the findings it was recommended among others that; the strategic management of AEDC should as a matter of urgency adopt the tenets of reliability-based maintenance as the most efficient maintenance practice.
