A SEMINAR PAPER ON “OVERALL EQUIPMENT EFFECTIVENESS: A CASE STUDY AT A BOTTLING PLANT”

Abstract

Overall Equipment Effectiveness (OEE) is the crucial tool of Total Productive Manufacturing (TPM). OEE evaluates the workability of the equipment in relation to its performance capacity provided that it should be operated in the optimal manufacturing conditions. It considers the whole manufacturing environment not merely the availability of the machine for performing the particular work, but also the efficiency of the product during the equipment availability together with losses in efficiency due to various factors such as yield waste, rework, scraps, etc. Such analysis provides a broad view of machine operation and manufacturing efficiency and assists to formulate efficient strategies to enhance the productivity of the manufacturing line. This paper implements the OEE tool to identify the root causes responsible for affecting system line efficiency. For this, a case study on a production line of VBNPL, one of the reputed beverage companies in Nepal working as the franchise of the international brand “PepsiCo. Int”, is done. Initially, the OEE of a single production line called “GRB 400” is calculated by recording the total planned breakdown, unplanned breakdown, and filler breakdown. Onwards, becoming specific the OEE of the Filler is computed and all possible reasons for the drop in the efficiency are identified, for instance falling of bottle, bottle burst, bottle jam, loose vent tube, etc. by using various techniques such as Pareto chart and Fishbone diagram. Finally, suitable recommendations are provided to mitigate the issues that hampered the efficiency of the production line.
