Abstract: A method for prospective planning and dynamic management of a flow processes comprising a plurality of interrelated and interdependant processes, resources and commodity flows using a computer system. The method includes providing a database containing information about the flow process and graphically displaying both the problem and the solution spatially and/or temporally. Indicia can be made to appear on the display to provide visual identification of symbols as well information about the solution, capacity, minimum levels, flows and variances. In addition, access to the data base can be made available either to update the display to reflect current information or to perform "what-if" scenarios. Access to the database is through objects displayed and permits a wide variety of information to be queried and displayed. The system also has the capability to communicate portions or all of the plan to other modules and to receive data from other modules.
