| Abstract: | Make use of cloud services to solve a real-time vehicle routing problem with stochastic demand(VRPSD) in the middle of coal logistics.Clients can access cloud service via Internet over HTTP protocol.They create computation tasks supplying simulation parameters.Presented solution uses safety stock and simulation to solve a vehicle routing problem with stochastic demand.Build cloud services and run the algorithm in parallel on the Windows Azure platform.Since all tasks are computed in parallel on the Worker nodes in cloud,so it can meet customer needs in real time. |
