OEE Improvement by Increasing Maintenance System Efficiency Through DigiPM and DigiBox

Abstract

PT Andromeda is experiencing a decline in market share compared to its local competitors, with a steady decrease in operating margin of 1-2% annually. To address this, the company initiated efforts to strengthen its business fundamentals and competitiveness in 2022. Within the Supply Chain, various activities are involved, from procuring raw materials to delivering finished goods to customers. To address these challenges, the proposed solutions are DigiPM and DigiBox which aim to establish a seamless connection between spare parts inventory management and preventive maintenance activities. Improving OEE is crucial for enhancing productivity and reducing downtime in manufacturing systems. This study examines the limitations of the existing maintenance system, highlighting three primary issues: inefficient spare part management, lack of clear inventory information, and insufficient knowledge sharing. To address these issues, a digital platform integrating maintenance activities with spare parts inventory is proposed. Through the application of CRT Analysis, the 8 waste of lean, and AHP under the framework of PDCA, DigiPM and DigiBox are developed as solutions, with DigiPM facilitating digital maintenance and DigiBox managing spare parts inventory. Post-implementation, OEE increases by around 4% from 2022, with significant reductions in breakdowns and minor stoppages. Repair and maintenance costs also show significant savings of 4 billion IDR. Maintenance digitalization provides data-driven insights, facilitates communication, enables report analysis, and prevents similar problems, serving as a learning system for technicians.
