Abstract: Reconfigurable manufacturing systems are considered to be one of the newer technologies which cannot only meet stochastic product demand but can also produce products having customised variety. The paper presents performance modelling of a reconfigurable manufacturing system equipped with dedicated and reconfigurable machines under the failure of any resource. The dedicated machines are assumed to be subjected to random failures or breakdowns and upon occurrences of such breakdowns or failures, the jobs from these machines are routed or dispatched to reconfigurable machines to carry out the desired operation after suitable reconfiguration. Different dispatching strategies under two production scenarios were simulated using ARENA® discrete event simulation software. Performance of dispatching strategies proposed was analysed in terms of productivity, congestion and make-span time. The results were analysed and were discussed in light of previous researches carried out on the topic.

Keywords: reconfigurable manufacturing systems; RMS; performance modelling; dispatching strategies; resource failure; performance evaluation; random failure; random breakdown; discrete event simulation; DES; productivity; congestion; makespan.
