一种新型多目标智能加权灰靶决策模型

提出一种新的多目标加权灰靶决策模型.针对具有满意域的效益型、成本型和适中型等不同性质的决策目标,构造出效益型目标效果测度、成本型目标效果测度、适中型目标下限效果测度、适中型目标上限效果测度等4种新型一致效果测度函数.据此可将具有不同意义、不同量纲、不同性质的决策目标转换为一致效果测度,从而能够方便地求出综合效果测度矩阵.将灰靶临界值设计为一致效果测度函数的正负分界点(即零点),充分考虑了目标效果值中靶和脱靶两种不同情形,物理涵义清晰,综合效果测度的分辨率也大大提高.

Multi-attribute intelligent grey target decision model

A new multi-attribute intelligent grey target decision model is proposed. Four kinds of uniform effect measures of the effect measure for benefit type objective, the effect measure for cost type objective, the lower effect measure for moderate type, and the upper effect measure for moderate type are formed in view of different decision objective of benefit type, cost type, and moderate type which with a pleased field. Accordingly, the decision objectives which with different meaning, different dimension, and/or different nature can be transferred to uniform effect measure. So, the matrix of synthetic effect measures can be obtained easily. The critical value of grey target is designed as the dividing point of positive and negative which is the zero point. The two cases of hit the bull’s eye or not of the objective effect value are fully considered. The distinguishing rate between synthetic effect measures is improved greatly.
