船舶总布置计算机辅助设计子系统的数据结构

本文针对船舶总布置设计涉及面广,信息多,难以用统一的数学模式表达的特点,采用仓名链式编码的方法定义仓室,以统一格式的共节点文件存取和传递信息,按有向图方式描述仓的内壁信息。这样构成的数据结构,不仅数据存取与传递方便,而且大大地减少了程序的工作量,同时也增强了程序的功能与可维护性。 该方法不仅适用于本子系统,而且也适用于其它有类似信息状态的工程技术方面的电子计算机系统。

DATA STRUCTURE OF THE SUBSYSTEM FOR COMPUTER-AIDED SHIP GENERAL ARRANGEMENT DESIGN

To solve the multitude of problems involved in ship general arrangement design, the large amount of information to be dealt with, and taking into account the difficulty of describing these problems in unified mathematical models, this present paper has adopted a chain-coding method for naming holds, tanks and accommodation compartments, wherein information is accessed and transfered by using unified common-node formats. The inner wall information of holds and tanks is described with the directed graphic method.This kind of data structure not only ensures convenience for information access and transfer, but greatly reduces the amount of programming work. Furthemore, it will improve the function of the program and its maintenability.This present data structure is applicable not only to the CAD general arrangement subsystem, but also to other engineering computing systems which involve similar information requirements.
