摘要
制造执行系统(MES)是制造车间生产管理信息化的重要技术手段,通过MES可以
实现对车间生产过程的可视化、实时化与精细化管理,从而显著提高车间的制造效
率、改普产品质量。本文以某军工企业导弹装配车间为应用背景,进行了导弹装配
MES系统的需求分析与总体方案设计,并研究了装配型MES中的生产调度技术。主
要研究内容如下:
首先,本文在对背景企业进行人量调研的基础上,结合MES理论,详细分析了装
配型生声车间对MES系统的需求,主要包括装配生产中的作业调度、实时数据采集、
物料跟踪、质量控制、工.具管理、设备监控等。
其次,结合企业现有的信息化建设现状,进行了装配型MES系统的总体方案设
计,提出了装配型企业的MES解决方案,包括系统体系架构构建、开发工具选择、数
据库设计及系统集成方案等
再次,针对现有装配作业计划排序方法的不足,应用最优生产技术和约東理论
(OPT/TOC),提出了一种基于瓶颈分解的启发式调度算法,可用于装配型MES中的
实时动态调度问题,并通过实例验证了算法的有效性
最后,对本文研究进行了总结,指出了军工行业装配型MES及其动态调度技术进
步的研究方向。

Abstract
Manufacturing Execution System (MES)is an important means for enterprise to
implement production management informationization. By implementing MES, enterprises
can remarkably improve the production efficiency and quality as a result of achieving real
time tracking and visual management in manufacturing process. Due to the importance of
MES in the production management, the MES for missile assembly manufactory and its
production scheduling on the background of a military enterprise is studied in the thesis
focusing on system demand analysis, system integrated design, and real-time scheduling
algorithm in MES. The main research contents are as follows
Firstly. the system demand of MES for missile assembly manufactory is analyzed in
detail based on the theory of MES and a great deal of investigation and study of the military
nterprise. The MES functional requirements of the assembly factory include: production
cheduling, real time data acquisition, materia tracking, quality control, tool management,
equipment monitoring and so on
Secondly, with the existing enterprise informationization, the MES solution for military
sembly manufactory is proposed, and the system design technology which involved system
architecture construction, development tools selection, database design and system integration
technology are introduced
Thirdly, considering the insufficiency of current shop-floor scheduling, a heuristic
algorithm based on bottleneck decomposition is proposed in order to solve the problem of
real-time and dynamic scheduling in MES. Besides, an example is given to validate the
effectiveness of the algorithm
Finally, the conclusions are drawn and the further research directions of MES and
dynamic scheduling algorithm are pointed out
Keywords: MES; Assembly shop; Production Scheduling; Bottleneck
