  • Device for aiding analysis of infeasible solution and unbounded solution
    Patent number: 5929858
    Abstract: A device and method aid in an analysis of a cause of one of an infeasible solution and an unbounded solution when mathematical programming fails to find an optimal solution for a model. A display unit has a display on which a process flow is created by a user determining a configuration of elements for the model, and an output unit for displaying the process flow on the display such that at least one of the elements causing one of infeasible solution and unbounded solution is distinctive from the rest of the elements.
