| Abstract: | The paper outlines the design requirements for alternative generation in DSS and discusses the inadequacies of the "what-if' simulation and traditional optimization methods in light of these requirements. The paper further elaborates on the appropriateness of GA as a tool for alternative generation in DSS for solving complex ill-structured problems. The method is illustrated using marketing mix problem in a simulated business environment. The results suggest that the GA- based alternative generation leads to promising diverse alternatives. An active DSS incorporating the proposed method reduces the time-consuming manual search for promising alternatives and provides a higher degree of man-machine collaboration. |
