Abstract

The evolving characteristic of changeable manufacturing systems requires design and assessment techniques that consider both the strategic and financial criteria and incorporate the reconfiguration aspects as well as fluctuations in the demand over the planned system life cycle. The economic evaluation approaches to reconfigurable and flexible manufacturing systems have been reviewed. A fuzzy multi-objective mixed integer optimization model for evaluating investments in reconfigurable manufacturing systems used in a multiple product demand environment is presented. The model incorporates in-house production and outsourcing options, machine acquisition and disposal costs, operational costs, and re-configuration cost and duration for modular machines. The resulting configurations are optimized by considering life-cycle costs, responsiveness performance, and system structural complexity simultaneously. The overall model is illustrated with a case study where FMS and RMS implementations were compared. System configurations generated from the proposed model are simulated to compare the life-cycle costs of FMS and RMS. The suitable conditions for RMS investments have been discussed.
