Project surface regions: a decision support methodology for multitasking workers assignment in JIT systems

This research develops a decision support methodology called project surface regions (PSR) via the use of discrete-event simulation and response surface methodology (RSM). It is used to assist production managers in determining the appropriate number of multitasking workers and the corresponding dynamic dispatching rule-pair when a JIT systemʹs behavior changes. A set of dynamic dispatching rule-pairs, including a new invented rule-pair, is considered to demonstrate the application of PSR.
