Abstract

A structured web-based decision-support system is proposed to enhance maintenance engineering for a double-row, single-stage steam turbine. The system integrates root cause analysis (RCA), availability analysis, failure mode and effects analysis (FMEA), and reliability modelling to determine appropriate maintenance actions within a sustainability-oriented framework. Operational data are analyzed using thermodynamic principles to establish a theoretical reference condition. The outputs from availability, FMEA, and reliability analyses are subsequently synthesized through RCA. A functional modelling approach based on structured analysis and design technique (SADT) and integration definition for function modelling (IDEF0) is employed to systematically organize maintenance analysis and decision-making workflows. Based on these analyses, prioritized maintenance actions are formulated to mitigate failure recurrence. A scenario-based evaluation demonstrates a reduction in administrative workload through automated documentation workflows. The system is implemented using a web-based architecture that enables distributed data access and incorporates centralized data storage and backup mechanisms to enhance data consistency.
