dc.description.abstractThe major objective of this study was to contribute to the improvement of the production of plywood panels at Jin Chen Xian (JCX), Sangmelima. Specifically, it was to assess the production and conversion efficiency through the identification of causes that influence the decrease in production and to propose solutions for improving business performance. We estimated the ratio of wood volume at the entry and exit of the production chain. Data was also collected from monthly reports of the company. We used the Ishikawa method to determine the causes of a fall in production. Direct observations and interviews with officials about the production chain was also conducted. The Pareto diagram was used to enable us propose methods of improving production. Based on the analysis of data, monthly plywood production was estimated at 327 m3. This result shows that the objective of the company's monthly output which is 1200 m3 had not been attained. Mean conversion efficiency is 37%. Factors that influence the conversion efficiency the type of employees, the equipment and maintenance problems. Machine maintenance is not very effective. There is lack of regularly control while and intervention for troubleshooting and repair is slow due to lack of spare parts. Based on the results of the Pareto diagram, we proposed solutions. It is clear that we must act on four axes which are lack of spare parts, regular machine breakdowns, some machines do not work like the splicer, a dryer and the equipments are outdated. Thus, working on these axes we eliminate 56.30% of the causes. It is therefore recommended to order spare parts for machinery, to ensure corrective and preventive maintenance of the machines, to operate machines splicers to increase the amount of faces for the manufacture of plywood and gradually renew the existing equipment.en_US
