城市原水系统计算机仿真模型设计

由于城市原水系统网络结构复杂、规模庞大、存在地区差异性等特征，针对城市原水系统的仿真模拟问题，通过对原水系统进行概念化分析提出由点、线、面基本元素所构成的原水系统概念化模型，运用面向对象技术设计了与可视化界面通讯的数据类、描述基本原素的对象类以及负责模拟仿真的模拟算法类，并针对网络拓扑结构的动态存储、关系还原、遍历算法优化以及与优化求解技术的接口设计等问题展开讨论。本文提出的仿真模型在深圳市水源调度管理系统开发中得到应用，结果表明运用面向对象技术设计的仿真模拟具有思路清晰、结构层次分明、更容易实现模块化功能等特点，并且能够保证模型的可扩展性，提高代码的重复利用率。

Computer Simulation Model Design for Urban Raw Water Systems

The urban raw water system has characteristics of complex network structure, large-scale, differences in different regional. Focus on the problem of computer simulation of urban raw water supply dispatch, a raw water system conceptualization model is proposed, which constitute with the basic elements of points, lines and units. Several class are designed using object-oriented technology, such as data class for communicating with user interface, object classes for describing basic elements and algorithm class for simulation controlling. Issues of dynamic storage and restore for network topology relations, optimization for traversal algorithm and design of class interface are also discussed. The simulation model has been applied in development of water dispatch and management system in Shenzhen City. It is proved that simulation model, which designed with object-oriented technology, has many advantages, such as clearer ideas, structured, easier for modular implement and so on. It is able to guarantee the scalability of the model and improve the reuse of code.
