Abstract:

In response to the difficulty in acquiring green design knowledge, designer profile matching, and the low efficiency knowledge recommendation throughout the lifecycle design of electromechanical products, various features involved in the designers' green design processes over the full lifecycle, including type, operational, knowledge, and task features, were identified. Then, feature quantization, weight optimization, and dimensionality reduction fusion were conducted. Subsequently, indicator functions for green design knowledge matching, including designer dynamic profile similarity, lifecycle feature distance, and knowledge greenness, were developed, and a corresponding matching model was constructed. Furthermore, a green design knowledge push mechanism was proposed based on the transfer prediction of designer profile, and an active green design knowledge recommendation method driven by full-lifecycle distance prediction and verification was established. Finally, an application validation was conducted using a new refrigerator model with green design requirements in terms of high volume efficiency, reduced material consumption, and low energy use. The results demonstrate that the recommended green design knowledge sets may effectively support designers in achieving green structural optimization and energy-efficient design for electromechanical products.

Key words: green design knowledge, knowledge push, designer dynamic profile, full-lifecycle characteristics, transfer prediction of designer profile

摘要:

针对机电产品全生命周期设计过程中绿色设计知识获取难、研发人员画像匹配和推送效率低等问题,表征了研发人员全生命周期绿色设计过程中各类特征,包含类型特征、操作特征、知识特征与任务特征等多个维度,并进行了特征量化、权重优化及降维融合;提出了研发人员动态画像相似度、全生命周期特征距离与知识绿色度等绿色设计知识匹配指标函数,并构建了绿色设计知识匹配模型;提出了考虑研发人员画像迁移预测下的绿色设计知识推送机制,建立了考虑全生命周期距离预测与检验的绿色设计知识主动推送方法。最后,基于某款新型冰箱的高容积率、低耗材、低能耗等绿色研发需求,开展了相应绿色设计知识匹配及推送应用验证,结果表明,该方法所匹配并主动推送的绿色设计知识集合能够有效启发研发人员实施机电产品绿色结构优化及节能设计。
