Abstract:

A paradigm for the time-managed control of material flow in job shop and small-lot environments which are subject to random disruptions is presented. The paradigm is implemented through a model which invokes certain special structures to investigate fundamental operating characteristics, including measures of kitting effectiveness. It is proven that schedules are most economically time-managed by co-ordinating vendor deliveries, rather than by deliberately delaying materials in-process. Fundamental results which permit scheduling and rescheduling are derived, along with certain performance measures necessary to time-managing flow effectively. Numerical tests indicate the accuracy of the model and demonstrate how material flows can be time-managed to minimize costs. The paradigm appears to be better suited than others for managing material flows in job shop and small-lot environments.
