Abstract: Aiming at the massive design resources,how to quickly and efficiently push the appropriate design resources to the needed designers had important significance to shorten the product development cycle.Therefore,cloud design resource modeling for product design was carried out.On the basis of the cloud design resource response capability model and the designer's demand and preference model,the cloud design resource scheduling mechanism based on negative feedback was constructed,the similarity matching between the cloud design resource response capability and the demands of designers was realized by solving this mechanism,and the cloud design resource node which had higher matching degree was reflected to designers to improved the utilization ratio of resources.Simulation and result analysis showed that the scheduling mechanism and algorithm could meet the needs of designers and improve the utilization of design resources in full measure.

Key words: negative feedback, cloud design resources, scheduling, demand, preference

摘要： 为了在海量设计资源中快速高效地将合适的设计资源推送给所需的设计人员,以缩短产品研发周期,提出面向产品设计的云设计资源建模方法,在云设计资源响应能力模型和设计人员需求与偏好模型的基础上,构建了基于负反馈的云设计资源调度机制,通过对该调度机制的求解实现了云设计资源响应能力与设计人员需求的相似度匹配,并将匹配度较高的云设计资源节点反馈给设计人员,提高了资源利用率。仿真及结果分析表明,该调度机制与算法能够最大限度地满足设计人员的需求,提高设计资源的利用率。
