项目型制造过程信息流集成建模仿真研究

项目型制造过程常见于造船、建筑等行业,针对现有面向流水车间的离散制造系统建模仿真方法不能有效表示、模拟这一过程的问题,以船厂船坞吊装为例,分析工艺要素结构,提出以作业网络为中心、信息流与作业流集成的仿真建模方法,设计了基于作业进程交互的仿真控制算法。使用Python语言开发了仿真程序原型,通过一组船坞吊装实际案例实验,验证了所提模型与算法的有效性,可以为离散事件仿真技术在项目型制造过程的研究应用提供借鉴。

Research on Information Flow Integrated M&S Method for Project Type Manufacturing Process

The project type manufacturing process is quite common in shipbuilding and construction industries. Aiming at the problem that the existing discrete manufacturing system modeling and simulation method for flow shop cannot effectively express and imitate this process, taking shipyard dock shop hoisting process as an example, we analyze its components structure, propose a working network-centric, information flow and work flow integrated simulation modelling method, and design a dedicated simulation algorithm with the task process interactive idea. A prototype simulation program is developed with Python language, and the effectiveness of the proposed modelling and simulation method is verified through a case study with a group of actual shipyard dock hoisting data, which can provide reference for the research application of discrete-event simulation technology on the project type manufacturing system simulation.
