本文主要介绍了在AutoCAD2005平台下的船舶管系支架系统,此系统以Viusal studio 2002和ObjectARX2005为开发工具,实现了管子支架的智能化设计.管子支架设计系统提供了11种标准管子支架,每一种管子支架又可以衍生出2~4种变体,这样基本上能满足船舶生产设计中管子支架的设计.本系统主要的特点是,能灵活创建形状复杂的组合式支架,能够自动的由设计好的管子支架三维图形生成二维工程图,用于管子支架的生产和安装. 相似文献

Manufacturing of ship piping systems is one of the major production activities in shipbuilding. The schedule of pipe production
has an important impact on the master schedule of shipbuilding. In this research, the ITOC concept was introduced to solve
the scheduling problems of a piping factory, and an intelligent scheduling system was developed. The system, in which a product
model, an operation model, a factory model, and a knowledge database of piping production were integrated, automated the planning
process and production scheduling. Details of the above points were discussed. Moreover, an application of the system in a
piping factory, which achieved a higher level of performance as measured by tardiness, lead time, and inventory, was demonstrated. 相似文献

There are many restrictions on production in the factory. The most efficient production schedule should be planned taking
these restrictions into account. Professional skill is necessary to plan the best schedule. A schedule planner has to deal
with so much information during production planning that it is difficult to plan the best production schedule with a consideration
of so many restrictions. In this study we introduced the use of Petri nets to support such production planning with a computer.
Petri nets have been widely used to simulate production because of their capability of modeling concurrency, synchronization,
and sequencing in discrete-event systems. This paper reports on implementing a simulation system for the shipyard. We had
already implemented a production planning support system for a shipyard that is a part of the computer integrated manufacturing
(CIM) system in shipbuilding. Based on this system, we implemented a shipyard simulator that can simulate the production activity
in the shipyard. We therefore have defined a shipyard model. The production conditions can be changed, and the efficiency
of a schedule can be evaluated. This paper discusses the effectiveness of using a factory simulator.

论现代造船体制的特征和实践 总被引:5,自引:1,他引:4
中国一流船厂的造船综合生产效率仅为国际水平的十几分之一。症结在于尚未建立起符合成组技术原理的现代造体制,笔者认为,混合工种的生产组织,流通量控制的生产管理,分道布置的生产流程和壳舾涂一体化的作业方法是现代造船体制之基本特征,其实质是柔性化的流水生产,笔者提出了以理论研究为牵引,造船之首道工序为起点,从改革最基层的生产组织,建立“微型工厂”做起的实施思路,同时,论述了结合江南造船厂新建管子车间,广州 相似文献
