摘　　要：航天发射试验任务快速评估系统基于层次分析的递阶层次评估模型,综合应用多线程、实时事件、封装调用、定时更新等技术和观察者、Null Object等设计模式,解决了动态耦合、多线程同步、跨线程更新UI、动态载入判据等实时性问题。试验结果表明,快速评估系统已经应用于航天发射任务,快速、准确、全面地完成了火箭实时飞行状态下的飞行数据评估。The fast evaluation system of space launch based on the hierarchical evaluation model for AHP,integrating some technical measures such as multithreading,real-time event driven,package calling,regularly update,observer pattern and Null-object pattern.It solves real-time issues of dynamic coupling,multi-thread synchronization,cross-thread updating UI,dynamic loading criterion.So far,the fast evaluation system of space launch has been applied to space launch mission,and complete the quick,exact and comprehensive fly-data evaluation of real-time flight data.
