产品配置是选择各种部件组成定制产品以满足客户个性化需求的基本手段。然而,当客户的要求太严格时,可能会出现配置冲突,从而找不到任何配置来满足客户的要求。在这种情况下,产品配置员建议用于生成有效配置的纠正措施至关重要。本文提出了一种应用约束满足来解决产品配置冲突的方法。在该方法中,配置冲突问题被编码为约束满足问题。因此,对配置冲突问题的解决可以看作是对CSP问题的求解。因此,系统会建议一些纠正措施,如删除选定组件或添加新组件。在有多种解决策略的情况下,采用多目标决策模型,根据客户偏好找到最优的维修策略。最后给出了一个算例,验证了该方法的有效性。
Product configuration is an essential means for selecting various components to constitute a customized product with the aim of meeting the individualized requirements of a customer. Nevertheless, configuration conflicts may occur when too strict requirements of the customer are given and thus any configuration cannot be found to satisfy the customer requirements. In this situation, it is vital important for a product configurator to recommend the corrective actions for generating valid configurations. In this paper, we present a method of applying constraint satisfaction to resolve product configuration conflicts. In the presented approach, the configuration conflict problem is encoded as a CSP (constraint satisfaction problem). Therefore, the resolution to the configuration conflict problem can be regarded as solving a CSP. As a consequence, corrective actions such as removing selected components or adding new components are suggested by the system. In the case of multiple resolving strategies, a multi-objective decision model is adopted to find the optimal repair strategy according to customer preferences. A computer configuration is illustrated to demonstrate the effectiveness of the presented approach.
