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
