(A) methodology of visual interactive multiple objective linear programming in the framework of decision support system

Abstract

Recently, in Mutiple Objective Decision Making (MODM), visual interactive method is one of the most interesting developments. And a graphic facility of Decision Supporting System (DSS) is very useful for userinteractive decision making. Unfor tunately, there are very few DSS for the visual interactive in MODM. In this research, a new methodology for multiple Objective Linear Programming (MOLP) is proposed and a visual Interactive MOLP System (VIMS) is developed, which visualizes the decision make (DM)``s preference pattern and a solution procedure. In this method, a search direction is determined using the relation of the DM``s preference and the outer normal vectors of efficient facets. VIMS provides with the useful information by means of various graphic displays and DM would be expected to solve the problem with ease and convinence.
