With the increasingly severe global market competition, the nature of enterprise competition has changed from competition among enterprises into the competition among supply chains. Lowering operating costs of the supply chain and responding to market quickly have become the main objectives of the supply chain management (SCM). The emerging grid workflow technology which can integrate heterogeneous...
Grid computing is the technology for building Internet-wide computing environment in which distributed and heterogeneous resources are integrated. However, in Grid environment, job scheduling is confronted with a great challenge. This paper focuses on lightweight jobs scheduling in Grid Computing. An Adaptive Fine-grained Job Scheduling (AFJS) algorithm is proposed. Compared with other fine-grained...
Grid resource management and scheduling are confronted with a great challenge. This paper presented a dynamic resource price-adjusting (RPA) strategy in computational Grid. Three new concepts and two new evaluation standards are defined. On the basis of these theories, a Grid resource scheduling algorithm based on marker-driven using dynamic RPA strategy is proposed. With the help of GridSim toolkit,...
Grid resource scheduling is one of the popular issues in grid computing research field. Ant colony algorithm (ACA) is an effective method to solve NP (non-deterministic polynomial) problems. By studying the process of resource scheduling in grid environment and ant colony algorithm for classic TSP problem, a strategy of resource scheduling based on ACA in grid environment was proposed. Then, the new...
In this epoch of global economic markets, an intense world-wide competition has impelled manufacturing industry to move toward the agile and high-effective manufacturing paradigm. All require a flexible, requirement-driven, and reconfigurable production system to adapt to this open manufacturing environment and to be subject to the requirements of the increasing reduction in product life cycle and...
Aiming at the inherent drawbacks of the traditional numerical control system based on industrial PC, the embedded numerical control service system based on Ethernet/Internet puts forward in the paper. The new system is constructed as a dual-CPU numerical control system, in which the ARM is defined as multi-machine NC management server that serve sharable functions for scheduling and execution control...
