Improving Sustainability Asset Performance Based on Dynamic Data Envelopment Analysis

Abstract

The success of an industry is often measured through sustainability performance because it serves as a benchmark of consideration for asset managers in carrying out actions, planning, and decisions. However, changes in the utilization of physical assets between entities impact not only the life cycle of these assets but also sustainability assets that will affect company performance in terms of controlling company efficiency. The DDEA method is an analytical method that can be used to assess the level of efficiency of the performance of sustainability assets. The performance of sustainability assets is measured using variable maintenance costs, asset availability, material consumption as an economic aspect, variable environmental impact costs, employee health costs, and accidents and incidents as social aspects. In addition, material rejects variables, hazardous waste, and energy consumption costs as environmental aspects. From the results of the analysis of sustainability asset performance through the DDEA method in the period 2018–2022, it shows that both before and after organizational changes have no significant impact. This is shown by the level of efficiency of sustainability asset indicators on the impact of organizational change found in DMU 1, DMU 2, DMU 3, DMU 5, DMU 6, DMU 9, and DMU 10. The achievement of constant or efficient conditions with input-oriented CRS efficiency is at a score of 1. While DMU 4, DMU 7, and DMU 8 show increasing conditions with input-oriented CRS efficiency at less than 1.
