IRTMM Value Analysis Module

We describe the Value Analysis Module (VA), which is part of the Intelligent Real Time Maintenance Management (IRTMM) project. The VA uses a decision-analytic approach to study the maintenance decision-making in a conventional steam power plant. Wc used two test cases from Southern California Edison (SCE) to validate the VA. In addition, a simulator was built to investigate the problem of scheduling multiple maintenance activities. The second half of this report studies three test cases from Pacific Gas and Electric (PG&E). The results show that the VA can handle individual maintenance activity very well. However, there are some problems remaining. A discussion of them and the implications for future research is presented at the end of this report.
