The Grid Simulation Platform Of ASCM Service Scheduling

With the development of modern agriculture, agricultural supply chain management(ASCM) system is becoming the core of agricultural development. Use grid technology to build the agricultural supply chain management system and give full play to the distribution, sharing, security, and other features of the grid can make the agricultural supply chain participants which may located in different areas are able to obtain, publish, update, delete the information of the process of agricultural production, processing and storage. Even more it can improve the level of information sharing of agricultural supply chain management and improve appreciation of agricultural supply chain. When ASCM system performs simulation tasks on the grid, the grid platform will find the right grid resources from the resource category tree(RCT) according to the needs of the service, so that it can achieve efficient use of grid resources.Grid resources as a basis for a grid system to run, its organization and management are particularly important. Agricultural supply chain management system are not only have great relationship to the organization of grid resources but also have great relationship to the type of grid resources, performance, reliability, etc.Based on this, this research on ASCM system grid simulation platform service scheduling has proposed grid resource management algorithm based on primary attribute clustering. First, by analysis to the property of grid resources to identify the main attributes of grid resources. Second, to use resources projected on each of the main properties to build an RCT. RCT has the ability to load the evolution of autonomous, dynamic maintenance capabilities of grid resources and high degree of fault tolerance by effective organization and management of grid resource. In the virtual organization(VO), each resource classification tree sent RCT entry information and general information of RCT to RCT Indexing Service(RIS). RIS is in charge of information exchanged with other VO so that it can improve the efficiency of resource search.Through the effective management of grid resources in agricultural supply chain management based on grid simulation platform and the HR in grid resource classification tree backup operation, so that the backup node can quickly take over HR tasks when HR node error and RCT can effective functioning.
