Abstract: Cloud manufacturing is desired to be self-organized, which involves the problem of resource integration and sharing.This paper presents a new resource integration method in cloud manufacturing based on distributed hash table (DHT).The novel method builds the structure of DHT overlay structure and the algorithm of node organization is presented by determining how distributed resources are integrated for cloud manufacturing.In response to the multi-dimensional attributes and interval distribution characteristics of manufacturing resources, this paper describes a quadtree-based approach and its related algorithms of how to search multi-dimensional attributes by range of value, which recursively subdivides the underlying resource space defined by the range of every selected attribute.Finally, this paper discusses the implementation strategy which reinforces the self-organizing property of cloud manufacturing.A prototype is built with the new resource integration and searching method, which validates the method and tests its efficiency.
