Optimizing Production Efficiency Through Total Productive Maintenance: a Case Study of a Vegetable Oil Production Company

Abstract

This paper aims to present an approach for optimizing production efficiency through Total Productive Maintenance (TPM), using a case study of a vegetable oil production company in Thailand. This study employed both qualitative and quantitative research methods. Data were collected using questionnaires distributed to 200 randomly selected employees from the production and maintenance departments. Prior to the implementation of TPM, the vegetable oil production system operated in a continuous series without backup systems at certain critical points. As a result, the average total equipment effectiveness (OEE) was 83.8%, which fell below the industry standard. After six months of implementing TPM focusing on Pillar 1: Focused Improvement, Pillar 2: Autonomous Maintenance, Pillar 3: Planned Maintenance, and Pillar 4: Education and Training the average total equipment effectiveness increased by 3.92%. This empirical study demonstrates the effectiveness of applying TPM to improve production efficiency in the cooking oil manufacturing sector. The findings suggest that company executives should consider extending TPM implementation across all departments for broader organizational benefits.
