Abstract : A Decision Support Problem Technique (DSPT) is used for the selection of a slow speed diesel engine for the propulsion of a proposed commercial cargo vessel satisfying strategic sealift requirements, and emphasizing reliability, maintenance, and repair factors. A two step procedure is utilized. In the first step, the initial set of five engines and engine variants is reduced to three candidate engines on the basis of generalized criteria. In the second step, engine attribute weights are found through the application of quality function deployment (QFD). Combining the attribute weights with engine attribute ratings generates merit function values for each engine. The analysis is performed with three of the seven attributes related to a reliability, maintenance, and repair criterion: component consumption rate, replacement part cost, maintenance cost(overhaul). The engine chosen is the MAN B&W 5 cylinder K90MC MK VI diesel.
