Warranty and Maintenance Decision Making for Gas Turbines

S. Chao, Z. Lee and A. Agogino

In this paper we describe ongoing research in the areas of maintenance and warranty decision-making for gas turbines used in power plants. We first frame the problem within a larger context of equipment monitoring, diagnostics and maintenance. We then focus on describing and modeling economic issues related to warranty maintenance service from the perspectives of both the consumer (power plant owner) and producer (General Electric). Finally, we develop a dynamic programming approach to optimize specific compressor maintenance activities for a fixed warranty period.
