摘要
在交通工程领域中常对公式组进行繁琐地计算,初始值及数学模型在计算中经常要修改。以往的编程模式将公式固化在程序内部因而无法修改数学模型,而应用EXCEL查阅公式较困难,容易误操作损坏文档。故此开发了"交通工程公式组计算系统",不要求用户掌握编程语言,就能对任意公式组展开计算,可在计算中动态地调整公式组结构,并设计了"自定义函数"功能以简化公式组的调用,对大的计算项目能实现多人分工协作。该系统已在我院实验和实习中稳定运行2年,应用范围从交通工程拓展至其它学科。
In this article, a comprehensive description is made of a newly developed computing system for traffic engineering formulas, through which, users may calculate the arbitrary formulas, even if they don＇t have a good command of programming language. The system can also revise the formula structure dynamically. At the same time, ＂self-defining function＂ is designed which can simplify the using course and make it possible for several people to share out a complicated calculation project. The system has been running for two years, expanding application from traffic formula group to other disciplines .
