基于目标偏离容忍水平的多目标交互式决策方法

提出了一种基于目标偏离容忍水平的多目标决策新方法．该方法充分考虑到了实际决策过程具有的目标多样性、主客观互动性等特点，根据目标希望水平和目标偏离容忍水平在原多目标问题的基础上构造辅助模型，通过求解辅助模型得到原问题的非劣解，并经过与决策者的反复交互将不同的目标偏离容忍水平整合入模型当中，最终得到满意解．本文的方法具有结构清晰、求解方便快捷、易于反映决策者偏好结构等优点．

A NEW METHOD BASED ON THE OBJECTIVE DEVIATION TOLERANCE LEVEL FOR MULTI OBJECTIVE DECISION MAKING

This paper proposed a new method based on the objective deviation tolerance level for multi objective decision making.With regard to the objective diversity and interactive between decision maker and model,the new method obtain the non inferior solutions for the multi objective problem by contructing and solving auxiliary model which is based on objectives aspiration levels and objective deviation tolerance level.Then through the interactive between the decision maker and the model,some different objective deviation tolerance level are integrated into the model and finally obtain the satisfactory solution.The method proposed in this paper possesses the merit of clear in structure,quickness and convinience in algorithm and effeciency in considering the preference of decision makers.
