First Claim
Patent Images
1. A device for aiding 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, said device comprising:
- a display unit having a display on which a process flow is created by a user determining a configuration of elements for said model; and
output means for producing said process flow display on said display unit such that at least one of said elements causing said one of an infeasible solution and an unbounded solution is distinctive from remaining ones of said elements,wherein said at least one of said elements is identified from a path name thereof, said path name being obtained from a variable name reported in a result of said mathematical programming, said path name corresponding to a process flow path in said process flow.

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.
