摘要
产品设计资源重用程度是影响企业响应市场需求时间和设计成本的关键因素.在明确定制化产品与资源重用关系基础上对定制化产品基因的表征方式进行界定,基于基因传导机理和定制化产品开发过程得出的产品资源重用策略分为复制重用、变异重用和突变重用三类策略.为方便人们选用策略,基于相似度分析对资源可用性进行评价,用欧氏距离法计算现有产品与定制产品基因体之间的相似度,并依据韦伯定律来设定相似度阈值以确定资源合理重用策略.最后以定制化可重构小型农业作业机的设计为实例验证该策略的可行性.
The degree of product design resources reuse is the key factor that influences the enterprise＇s response time on market demand and the costs of design.The characterization way of customized products gene was defined based on the relationship between customized products and resource reuse.Three kinds of the strategy of resources reuse which included genetic reuse,variation reuse,and mutation reuse were obtained based on genetic and the development process of customized product.For the convenience of the choice to the strategy,the availability of resources was evaluated based on the similarity analysis,the similarity between existing product gene with customized product gene was calculated by Euclidean distance,and the similarity threshold was set based on Weber＇s law to determine the resource reuse strategy.Finally,the strategy was verified by a design example of customized reusable small agricultural machinery.
