Given the condition of multi-demand sites, multi-variety emergency materials and roads with forbidden time window, the mathematic model and simulation model based on NCL are set up, and heuristic arithmetic based on POEM is designed in the paper. At last, the model and heuristic arithmetic are validated by an example and the satisfying result is gained.
Network-grid computing is widely adopted in complex data computing and distributed data processing. In order to construct loosely-coupled application, the scientific workflow technique was used to invoke distributed services and data. However, there are many drawbacks in current scientific workflow system such as the complexity of manipulation and the difficulty of system deploy. In this paper, aims...
Due to the urgent requirements of mass data processing in the field of astronomy, with the advent of network grid computing techniques, a scientific workflow technique was presented and quickly adopted for distributed astronomical data processing. However, current existing scientific workflow systems are too complex and enormous in system deployment and system manipulation. Few people can master it...
