Abstract : The paper describes a dynamic multi-commodity, multi-mode network flow model which permits time phasing of commodity load inputs and derives delivery schedules to the respective destinations over a time span of interest to the user. The model makes use of a time-expanded network. Methodology for time expanding a basic network is described and an algorithm for determining the commodity flow allocations is provided. Implementation of the model has been made. A number of innovative programming steps which make possible very efficient processing are described and computing experience with several different network problems is reported. (Author)
