| Tiivistelmä: | The postoptimality analyses of the transportation problem are considered by a new approach developed through the use of perturbation analysis. In contrast to the usual sensitivity analysis the proposed methods allow for simultaneous, independent perturbation of the supplies , demands and transportation rates cost from their nominal values whilst preserving the current optimal basis. The proposed approach permits computation of the maximal allowable additional units and distribution of these extra units in a systematic manner. The proposed unified procedures are demonstrated by numerical examples. |
