  7. Abstract:
  8. The dynamic nature of today’s manufacturing industry, which is caused by the intense global competition and constant technological advancements, requires systems that are easily adaptable with new functions and technologies. In fact, a highly responsive manufacturing system is needed in which, introducing new products, adjusting system capacity with demand fluctuations and integrating new technologies with the existing ones are quickly possible. Reconfigurable Manufacturing systems (RMS) are a relatively new paradigm in industry that enable rapid adjustments of production capacity to changes in product mix and volume through their main characteristics including modularity, scalability and convertablity. Even though the importance of an elaborate configuration design for a manufacturing system cannot be overlooked, the dynamic nature of an RMS makes implementing quick and cost-effective approaches towards the design and reconfiguration, even more fundamental.The main problem addressed in this thesis is configuration design of a scalable reconfigurable manufacturing system which is capable of producing a specific product or a product family. To this end, particular emphasis is put on the modularity characteristic of a reconfigurable manufacturing tool (RMT). By focusing on RMTs’ ability to perform different operations on a part through changing and transforming modules, a scalable RMS is designed that can handle demand fluctuations through products’ lifecycle.All implemented solving approaches in this thesis are based on mathematical modeling. According to the underlying assumptions, in case of variations in products’ demand, the proposed models guarantee the lowest cost solution for system reconfiguration through RMTs transformations and/or purchasing new equipment. Analysis of the obtained results, for designing an RMS around a single product or a part family, indicate the importance of machine reconfigurations and considering different production capabilities of modular RMTs, in obtaining economical results for RMS configuration design
