摘　　要：结合面向服务的体系结构(Service-Oriented Architecture,SOA)的思想,依托工作流引擎技术建立一套任务调度框架,以满足气象预报管理任务对业务节点、流程和场景灵活便捷调度的需求。通过实现以节点为中心的功能算法一体化管控,满足流程节点构件化注册和资源复用;通过可配置的流程装配模式,实现在气象预报业务任务的快速编排;通过流程场景描述和状态可视化跟踪的模式,实现对业务流程全生命周期的可视化监控。该研究成果在气象预报管理业务系统中得到应用,取得较好的效果。Based on the workflow engine technology associated with service-oriented architecture(SOA),this paper explores a task scheduling architecture for weather and climate management operation,which meets the needs of flexible and convenient scheduling and control of operation nodes,processes and scenarios.Through the integrated management and control of the node-centered function algorithm,the component registration and resource reuse functions of the process nodes are realized.Through the configurable process assembly mode,weather and climate management can be changed quickly by service choreography.By the capability of visual process choreography,it is possible to monitor the processing of various processes accurately and conveniently.After the trial operation of this architecture which has been put into operation,the real-time operation requirements can be satisfied.
