基于互联网的重力式码头CAD集成系统

Transfer port structural design and optimization system onto Internet

应用Web、Java及分布式并行编程技术,将已有的重力式码头CAD集成系统设计平台从个人PC向互联网转移而形成其网络应用系统WebGWCAD(webbasedgravitywharfCADsystem).利用小程序(JavaApplet)编制客户端,利用JavaServlet扩充Web服务器进行系统调度,通过互联网充分利用远程PCs集群的强大计算能力对码头设计并行优化选型,计算结果及工程文档可以由用户下载到客户机或直接由小程序进行后处理,作为对工程分析设计软件网络化应用的探讨.WebGWCAD可以为相似软件系统的网络化应用提供一个思路.

By using Web, Java and distributed parallel programming technology, the author moved the Port Structural Design and Optimization System onto the Internet. With Java Applet as client interface, Java servlet extended web server as a control center, PCs cluster with parallel FEA ability as a computation center, custom protocol implementation as the communication layer, the web-based system can increase the design efficiency by several times. In order to make this system applicable, a new concept, charging for service, is put forward. With successful tests on some private LANs, new ideas for operating similar software system should be offered.
