Abstract: In order to share and apply information and service provided by suppliers and co-operation partners in wide area environment, and to finish the task of equipment remote service and fault diagnosis, grid technique was applied to construct remote fault diagnosis system, which was characterized by open framework, general standard and norm, and the special features in the way of distributional and parallel calculation and analysis. In the system, expert knowledge, checkout equipment, analysis software, equipment information, etc in wide area environment were defined as service resources, and expressed in the form of resource nodes. The development, management, action strategy and mechanism of resource nodes were elaborated, and then it was pointed out that the organization and optimization dispatch of resource nodes was the key of the system realization. Combined with multipurpose decision-making process model under the constraint condition, the mathematical planning procedure was expanded to solve this question in detail, and the feasibility of the algorithm was verified by a real instance.
