Efficiency Measurement on the Effectiveness of Train and Wagon Maintenance: A Data Envelopment Analysis Perspective

Abstract

This research aimed to measure and analyze the relationship between effectiveness and efficiency of train and wagon maintenance in three Decision Making Units (DMU) of Balai Yasa, Indonesian Railways Company (KAI) . It focused in both output and input orientation together with the effectiveness production. Descriptive qualitative used as the research methodology with Data Envelopment Analysis (DEA) and Overall Equipment Effectiveness (OEE). The input variables were maintenance costs, spare parts inventory and people operating hours, while output variable was OEE. To examine the relationship of effectiveness and efficiency, the stepwise approach method with backward method steps is used. The results showed that DMU 2 is efficient while DMU 1 and DMU 3 are not efficient, this is indicated that the more effective the organization is, the more efficient the organization is. DMU 2 has the highest effectiveness value for 86.19% while DMU 1 and DMU 3 are not yet effective with value less than 85% which means it needs improvement in the production department. Therefore, it can be concluded, all DMUs are efficient, meaning the greater the output revenue) organization, the organization will be more efficient . Normal 0 false false false EN-US X-NONE X-NONE
