A further study on inverse linear programming problems. (English) Zbl 0971.90051
Summary: The authors continue their previous study [J. Comput. Appl. Math. 72, 261-273 (1996; Zbl 0856.65069)] on inverse linear programming problems which requires us to adjust the cost coefficients of a given LP problem as less as possible so that a known feasible solution becomes the optimal one. In particular, they consider the cases in which the given feasible solution and one optimal solution of the LP problem are 0-1 vectors which often occur in network programming and combinatorial optimization, and give very simple methods for solving this type of inverse LP problems. Besides, instead of the commonly used $$l_1$$ measure, they also consider the inverse LP problems under $$l_\infty$$ measure and propose solution methods.
