A concurrent approach to hierarchical selection of design concepts for maintenance management is introduced. The interactions amongst selection problems in maintenance are taken into account concurrently by formulating an entire hierarchy as a single coupled Decision Support Problem (DSP). Using this method is possible to model interaction among different concepts rather than creating a model in which these decisions are made sequentially, hence this approach can form a basis for concurrent engineering. We illustrate our approach by formulating and solving a gas turbine axial compressor fouling maintenance problem as a coupled selection-selection DSP. The filter for fouling prevention and the washing media for fouling treatment are selected simultaneously while interaction between the two selections are considered. Our focus in this paper is on explaining our approach rather than the results per se.
