Abstract

Prioritization of component of offshore system for intervention based on Multi-Criteria Decision Analysis technique is significantly influenced by the weights of criteria. Unfortunately, almost all known process of weight elicitation suffers one form of uncertainty or another. The situation becomes more challenging when finding weights for criteria considered ingeneric sense: weights have to be adapted each time a new and different structure is investigated. This paper describes the process of dealing with such challenges and other sources of uncertainty in MCDA process. First it gives a clear interpretation of weight and proposes SWING methodology based on simplicity and transparency. Swing method reflects on the criterion-specific scores elicited for the alternative to determine appropriate weights for the criteria, thus is suitable for handling such situation. The process is demonstrated on a case study of a wave energy converter for indicative purpose only. The result shows prospect for large scale application.
