ABSTRACT

Maintenance is critical to organizational success and sustainability. Poor maintenance may lead to low productivity and a lack of competitiveness. Maintenance performance measures should be aligned with organizational goals. The study objective is to determine the overall maintenance performance using some maintenance metrics aligned with organizational goals.

The Fuzzy Logic Method (FLM) was combined with the Analytical Hierarchical Process (AHP) to evaluate organizational maintenance performance. To demonstrate the utility of the approach. A production enterprise was selected. The FLM was used to quantify the elementary indicators, allowing for the resolution of challenges related to a shortage of time, funds, and expertise. The AHP was used to weight each indicator to determine relative significance based on stakeholder ranking. Six strategic factors were considered: technical, financial, internal process, support, human resource, and health safety and environment. These combined (FLM and AHP) yielded an overall maintenance performance of 0.79, indicating that 79% of strategic objectives were met. The technical, financial, and internal process features contributed 70% of the overall maintenance performance. Therefore, these should be the focal points for any continuous improvement programs.

The two-stage model aids in the identification and prioritization of the most important indicators for evaluating organizational maintenance performance.

Keywords: Overall Maintenance Performance, Fuzzy Logic, Analytical Hierarchical Process, Sustainability, Strategic Objectives
