通过分析案例决策(CBDT)的经验理性,提出了可用于创新设计的案例决策方法.首先分析偏好反转的内在机理,指出CBDT中的案例对决策结果存在的潜在影响;然后提出一种判别无关案例和启发性案例的方法以及基于阈值的案例决策方法;最后通过摩托车发动机的产品创新设计的应用案例,说明了所提出方法的决策步骤.该方法与案例推理(CBR)方法相比,对于创新设计具有更好的实用价值和现实意义.
By analyzing the empirical rationality of case-based decision-making (CBDT), a case-based decision-making method that can be used in innovative design is proposed.Firstly, the intrinsic mechanism of preference reversal is analyzed, and the potential impact of cases in CBDT on decision-making results is pointed out. Case and inspiring cases and threshold-based case decision-making method.At last, the decision-making steps of the proposed method are illustrated through the application cases of motorcycle engine product innovation design.This method is compared with case-based reasoning (CBR) Innovative design has a better practical value and practical significance.
