Feasibility study of a computerised maintenance management system for a unified road electrical asset monitoring system.

This research investigates the feasibility of integrating a Computerised Maintenance Management System (CMMS) into the Road Electrical Asset Control & Telemetry (REACT) system for managing public road electrical assets. The study focuses on the Public Works Department (PWD) Selangor's implementation of REACT, with emphasis on traffic lights and street lighting, excluding other assets such as underground cables, closed-circuit television (CCTV), and flood monitoring sensors. The research aimed to: (i) identify the key requirements for effective maintenance of road electrical assets, (ii) develop a CMMS model tailored for integration with REACT, and (iii) evaluate the operational feasibility of the proposed integration using quantitative and qualitative assessments. A mixed methods approach was adopted, consisting of three methodological components: (i) document analysis of maintenance records, system documents, and asset-related forms; (ii) Monte Carlo simulation of failure breakdown scenarios patterns and simulation iterations to estimate improvements in resolution times; and (iii) a focus group discussion (FGD) with PWD stakeholders, analysed thematically to assess operational readiness, system gaps, and user expectations. These complementary methods enabled triangulation of findings to assess the technical suitability, performance impact, and user acceptance of the CMMS REACT model. The results indicate three major findings. First, REACT already contains CMMS compatible features such as asset inventory, alert notifications, and multi brand device integration, demonstrating a foundational readiness for integration. Second, simulation outcomes showed measurable operational improvements, including an 11% reduction in fault resolution time after applying CMMS based scheduling, work order structuring, and maintenance tracking. Third, stakeholder insights highlighted enhanced preventive maintenance, fewer emergency repairs, and improved data centralisation as key benefits, while also identifying gaps such as inconsistent historical repair data and the need for user training and workflow standardisation. Overall, the proposed CMMS to REACT model offers a structured, data driven framework for transitioning from reactive to proactive maintenance management. The study contributes to the body of knowledge in infrastructure asset management by providing an empirically validated integration model and demonstrating its applicability within a Malaysian public-sector context. The findings offer a replicable approach for public agencies aiming to improve asset reliability, extend lifecycle performance, and optimise resource allocation.
