A transshipment problem linear programming was chosen as basic analytic platform for Mathema-tical modeling of strategic development logistics systems, where the intermediate nodes were potential candidates for the location of specific facilities. In flow planning problem network reconfiguration made by relocation of the potentials of the main supplies with changing of the input parameters. Based on the daily update of the network structure, the optimal distribution of the product flows from the sources through intermediate points to sinks made by the location of new supplies and by the allocating of clients to them. The investigation sets the formulation mathematical model of the transport location-relocation problem of linear optimization and solution with Excel. The model simply implements additional tasks (such as a multicommodity problem or dividing the flows of various resources in transport corridors), and adding boundaries (bottom/top) to the values of the expected changes for its adaptation to real condition. Confirmed that with relocation of supply potentials, number of new facilities is minimal and it will always be placed near client nodes according to the criterion of minimization of transport cost. It intended for balancing the reproductive system for complete satisfaction of demand of clients in the absence of imbalance. Fig.: 4. Refs: 15 titles.
