Multi-State Reconfigurable Manufacturing System Configuration Design with Availability Consideration

Abstract

The capability of a reconfigurable manufacturing system (RMS) configuration depends upon its availability to meet demands. This chapter presented a multi-objective and multi-state reconfigurable manufacturing systems model for optimal configuration selection. Two objectives were considered, namely, total cost and availability for optimal configuration selection. The availability of RMS was estimated using the modified universal generating function (UGF). An integrated objective function is formulated in this chapter considering total cost and availability of system. The decision makers considered various scenarios for configuration selection, such as no weight, 50–50% weight and 40–60% weight for total cost objective and availability objective. According to weights, Option-1 was found optimal for scenario with no weight and 50–50% weight for total cost objective and availability objective. Option-2 was found optimal for scenario with 44–60% weight for total cost objective and availability objective.
