摘要： 为了给航班延误预警平台提供图形生成服务，设计并实现航班延误预警图形组件包，用于自动生成航班延误波及DAG、高级Petri网、贝叶斯网络和元胞自动机等数学模型的仿真视图，以及棒图等统计图。图形组件包包括外层服务和核心引擎两部分。外层服务生成图形XML文档，核心引擎解析该文档并渲染生成图形。图形组件包以Web服务暴露接口，以XML作为数据交换媒介，提高了互操作性和通用性。实验表明，该图形组件包可以有效满足航班延误预警平台的图形生成和表现需求。

Abstract: To provide graphs generating service for flight delay predicting platform, a graphic component package is designed and implemented. It can be used to automatically generate simulation graphs of flight delay propagation DAG, advanced Petri net, Bayesian network, parallel cellular automata, and statistical graph such as bar graph. The graphic component package consists of an outer layer service and a kernel engine. The outer layer service generates graph XML document, the kernel engine pareses it and renders graphs. The graphic component package exposes its interfaces through Web services and uses XML as data exchange media to improve interoperability. It shows that the graphic component package can effectively meet the requirement of graphs generating and representing of the flight delay predicting platform.
