Abstract: The present application describes a method and systems for enterprise supply chain optimization by accounting for time, cost, product demand, capacity constraints, and other factors. The described application relates to solving for the optimal flow of products through a supply chain including overseas vendors and a selected set of import gateways by using a custom-built model based on linear programming techniques. The model described in the present disclosure relates to a model that optimizes the overall cost or time (or a balance of both cost and time) to ship products from origin ports to domestically located distribution centers. By doing so, the model also optimally allocates how shipping containers are sent to domestic ports. The model subsequently outputs the optimal flow, cost, and time for each route in the network, as well as providing other relevant output.
