基于偏好的产品设计方案决策模型

分析了传统离差最大化决策方法的局限性,并以离差最大化模型为基础,在充分考虑设计决策者主观偏好的情况下,结合最大离差和最小离差,构建了一个新的基于偏好的产品设计方案决策模型。通过实例验证了该模型的可行性,基于实例对该模型进行了敏感性分析。结果表明,在传统离差最大化模型基础上引入决策者对设计方案的偏好信息,可以获取令人满意的设计方案。

Preference-based decision-making model for product design

Having analyzed the limitations of the traditional maximum deviation decision-making theory,this paper has established a new,preference-based model of decision-making for product design with the subjective preferences of design decision makers,the maximum deviation and the minimum deviation fully considered.The feasibility of the model was confirmed by a specific example,and the reliability of the model was analyzed on the basis of calculation results.It is shown that this preference-based decision-making model can be used to solve preference problems in decision-making and ensure a satisfying design solution.
