以觀調法求解多目標決策問題

Abstract

許多決策問題的求解程序，常是邊看邊調的。本研究發展一邊觀察邊調整(seeing-moving)的互動式方法，求解多目標決策問題。運用此方法所製作出的系統(S-MODM)，能產生視覺化的資訊以輔助決策者做求解多目標決策關係判斷。S-MODM首先基於一個參考點，將多目標間的關係轉換成數對二維圖形。決策者邊觀察每一二維圖形邊調移目前參考點至最佳點；再令S-MODM產生更新後的二維圖形組。若決策者在『觀』與『調』過程中，所表達之偏好訊息有一致性時，此方法會收歛求得一個最佳解。

Many decision processes are “seeing and moving” procedures. This study proposes an interactive seeing-moving method to solve multiobjective decision problems. A software system (S-MODM), which is developed base on this method, can display visual information about multiobjectives to the decision maker to assist him making better choice. S-MODM will fist generate a set of two-dimensional graphs based on a reference point, the decision maker then “see” each of these graphs and “move” the current reference point to a preferred new point. After that, S-MODM updates the visual information about these objectives to ask the decision maker to make next choice. If the decision maker can express consist preference during the seeing and moving procedure, this method would obtain an optimal solution.
