• Resumen

  • In this study, maintenance related data of a cocoa processing industry in Akure, Ondo State of Nigeria were collected, classified and analysed statistically. Linear Programming (LP) model was formulated based on the outcomes of the analysed data. The data analysed includes maintenance budget, maintenance cycle, production capacity and waiting time of production facilities in case of failure. Data were analysed based on manpower cost, machine depreciation cost and the spare part cost, which were assumed to be proportion to the number/magnitude of the breakdowns. The generated LP model was solved using software named “the Quantitative System for Business- QSB (Version 3.0). The results of the model showed that four maintenance crews were needed to effectively carryout maintenance jobs in the industry. The sensitivity analysis showed that the results have a wide range of feasibility.
