Abstract Reconfigurable manufacturing system (RMS) is designed around a specific part family. Reconfigurable machine tools (RMT) is the core facility of RMS. One RMT system is an RMS consisting of only one RMT. So, the RMT of one RMT system is designed for a specific part family, which integrates the characteristics of RMS and RMT. The reconfiguration path problem of one RMT system is an urgent problem to be solved. Therefore, an optimal reconfiguration path decision method for one RMT system is proposed in this paper. The objective is to produce the entire part family at the minimum reconfiguration effort. Reconfiguration time is adopted as the characteristic value of reconfiguration effort in this paper. The Tabu Search algorithm (TS) is used to solve this problem due to its excellent search ability. Process rule is considered during computation to obtained reasonable solution. A case study is given to implement the proposed method. The result shows that the proposed method can produce an optimal reconfiguration path for one RMT system satisfying the process rule.

Abstract We propose a systematic approach for product flow configuration selection for reconfigurable manufacturing system (RMS) that considers ten industrially relevant most important factors. The paper first defines performance metrics for the identified factors. A composite performance metric (CPM) has been proposed, which accounts for all ten-performance metrics to assess the performance of RMS with the help of a combined score. The methodology of developing CPM applies analytical hierarchy process (AHP) approach where weightage to each of the performance metric is also considered. To showcase the usefulness and feasibility of the CPM, it has been applied in an industrial environment with the help of an industrial case study. Both the CPM and other metric scores were found to be quite useful to identify a suitable configuration out of the available alternatives.

It is generally considered that economic feasibility of a reconfigurable manufacturing system (RMS) is only attainable if the system is defined to be reconfigurable at the outset of its design. In this work, we consider the potential exception to this perception, in the context of a common industrial scenario where a specialized and expensive manufacturing machine or system will otherwise be rendered useless due to the loss of business of the particular product being manufactured. Specific guidelines to convert from a fixed to a reconfigurable system are proposed, and evaluated through a case study. It is shown that under certain conditions, RMSs may be economically feasible even if they are developed through the modification of pre-existing dedicated systems.
