Multiple Criteria Visual Interactive System with Focused Contouring of Efficient Criterion Vectors
A multiple criteria DSS MC-VISA (Multiple Criteria Visual Interactive System utilizing Approximation) is introduced. MC-VISA is composed of four subsystems: 1) Model manager helps a DM to build, save, retrieve, and edit MOLP models; 2) ASEOV presents the stepwise focused structure of efficient criterion vectors and generates candidate goals for new search directions; 3) VIM displays the efficient trajectories along the search direction and acquires the DM’s preference; and 4) Mediator interfaces the three components and guides a DM through the decision making process. Menus and interactive uses of computer graphics allow a DM much flexibility over problem solving with MC-VISA. MC-VISA is designed in Turbo-Pascal on a personal computer. An illustrative problem solving with MC-VISA is provided.
