Coding, evaluation and optimal selection of a mechatronic system

This paper presents Multi Attribute Decision Making (MADM) based methodology for evaluation and selection of a mechatronic system. An exhaustive list of attributes which influence the structure and performance of a mechatronic system are identified. An attribute based coding scheme for identification and differentiation of mechatronic systems is developed. A three stage selection procedure is proposed for optimal selection of a mechatronic system. In the first stage, large numbers of available mechatronic systems are converged to a manageable number using elimination search. Second stage, a matrix for storing all the information pertaining to a mechatronic system alternative is proposed. In the third stage, all the mechatronic systems are ranked according the Euclidian distance of mechatronic system from best possible and worst solutions. Two visual methods namely linear graph and spider chart are proposed for ranking of mechatronic systems. An illustrative example explaining the implementation procedure of proposed methodology is discussed at the end. This methodology is useful for industries in selection of a mechatronic system and also useful for any customer in selection of an optimal mechatronic product.
