2604	 An Interactive Graphic Display for Region Partitioning by Linear Programming	 Using linear programming an interactive graphic display system has been implemented to solve the region design problem of partitioning a region into N nonoverlapping subregions in such a way that their areas are in specified proportions and that the total cost of servicing them is a minimum. In a conversational manner a user can easily obtain different partitionings by specifying and modifying the boundary the service centers locations the area proportions and the cost functions. Examples are included. interactive graphic display region partitioning area specification linear programming
