Abstract: The objective of this study was to provide a scheduling solution for the mixed priority queues discipline. This simulation model integrates Analytic Hierarchy Process (AHP) and Value Engineering (VE) for modelling and assessment of complex production systems with mixed queue priorities and service discipline. In such systems, the arriving entity will be placed in the queue according to the spectrum of similar properties; this spectrum is arranged according to the entity currently being serviced. In addition, each machine is only allowed to service identical products up to a limited period and the service turn over moves clockwise.

Keywords: queuing priority; computer simulation; AHP; analytical hierarchical process; value engineering; scheduling; mixed priority queues; modelling; complex production systems.
