| Grid technology is the basic establishmnent which puprose is to integrate distributed resources for co1laborating work. It provides an open platform of sharing and collaborating work for distributed resources and service. In the domestic and international academic circles at present, grid researches emerge in endlessly, grid technology has got much attention and it has been applied in the commerce domain. However, the grid theory is still immature, many key problems are eager to be resolved and uniform models have't been set up in many aspects. Numerous grid applications are still separate, which lack an automatic collaboration mechanism in the whole scope and the intelligence level of grid is not high. At present, one of the key problems is how to effectively improve the cooperative work ablity and intelligent level among the entities in the distributed computing enviroment like grid. It has great significance to study how to effectively improve the cooperative work ablity and intelligent level among the entities in the distributed computing enviroment like grid.This dissertation studies the grid collaboration models and mechanisms from collaboration sustaining administrative level on the base of such theories and technologies as grid computing, distributed artificial intelligence and CSCW. First, the grid collaborative model is proposed and described, which contains user service layer, coordination layer, cooperation percerption service layer, distributed service layer, information services layer. Then analyze the grid cooperative management with these inspects, such as the collaboration level, collaboration management objectives, the management of collaboration members, and interaction management. Finally, the collaborative framework based on Role-community/social intermediary of grid is instructed, based on which the medium service collaboration mechism is presented. This mechism erects a hierarchical collaboration relation among grid entities, realizes the flexibility, expansibility and condensablity of the system, improve the level of intelligence . |
