Abstract: Manufacturing processes have become more complex in the advance technology. Spectrum disciplines make a big challenge in some manufacturing and production systems that have to follow dependent sequences. This study presents a method for modelling of complex production systems with mix queue priorities and service discipline. In such systems, each group of jobs is allowed to be in service for limited amount of time. Jobs that have similar group number with the job in service will be located in the highest priority position and other groups are ranked in a queue according to spectrum discipline. The objective of this study is modelling of complex manufacturing and production systems with dependent priority queues where no closed form expression and mathematical models have been developed. A case study is presented to show applicability of the model. The approach of this study for such complex settings may be easily extended to other similar production systems.
