OEE Improvement by TPM Implementation: A Case Study

The manufacturing industry has gone through significant changes in the last decade. Competition has increased dramatically. Customers focus on product quality, product delivery time and cost of product. Because of these, the organization should introduce a maintenance system to improve and increase both quality and productivity continuously. Total Productive Maintenance (TPM) is a methodology that aims to increase the availability of existing equipment hence reducing the need for further capital investment. The aim of this paper is to study the effectiveness and implementation of TPM programme in an automobile manufacturing organization. Through the case study of implementing TPM in an automobile manufacturing organization, the increase in efficiency and productivity of machines in terms of Overall Equipment Effectiveness (OEE) are discussed. On the basis of results a database has been prepared which can be further used. The paper is organized as: Section 1 gives introduction about maintenance function. Section 2 discusses literature review regarding development of TPM. Section 3 gives details about the steps in implementation of TPM. Section 4 describes detailed TPM implementation in the case company. The improvements in OEE after TPM implementation are described in Section 5. Section 6 discuses the results and conclusions of the work. Section 7 describes the scope of study.
