A TECHNIQUE OF OBTAINING THEORETICAL VALUES IN DECISION MAKING FOR SELECTION OF FLEXIBLE MANUFACTURING SYSTEMS

In this paper, a relevant Technique, applied to obtain theoretical values through Chi-Square Statistics based decision making method, is proposed for evaluation of alternative flexible manufacturing systems, and obtained the same alternative (rank of FMS-II) which not deviated from other existing techniques of evaluating ranks of FMS (flexible manufacturing systems) for a given FMS problem.

The Chi-square statistic used as simple technique to find ranks FMS (flexible manufacturing systems) for a given FMS problem. As this technique used, looks, Good ness of fit test, but we considered to obtain ranks FMS in simple way as it compared to other existing techniques (in our point of view) and the way of obtaining theoretical values is also simple approach with the matrix multiplication. These theoretical values through Chi-Square Statistics, evaluates and ranks flexible manufacturing systems for a given flexible manufacturing systems selection problem. Solvers may not able to detect, such problems on their own, a possibly big time saver in the long run is preprocessing to bring the problem into the simplest way. An example is included to illustrate the technique.
