Toward a cloud-based manufacturing execution system for distributed manufacturing

This paper illustrates the needs and challenges for the management of distributed manufacturing in a multi-company supply chain and processes these further as features of new IT systems. Requirements are collected from manufacturing companies and combined with insights from literature in the field of current ERP/MES system drawbacks, advantages, needs and challenges. The findings show that the needs and challenges in data integration inside SME networks are closely related to the limitations of current supply chain solutions. Current ERP-solutions lack extended enterprise support and a shared cloud-based approach. On the other hand, current MES solutions can operate the manufacturing process, but not for distributed manufacturing. As an answer to the requirements, we made a proposal for the core of architecture for next generation of MES solution in this position paper. Moreover, a pilot software tool has been developed to support the needs related to real time, cloud-based, light weight operation.     

流程工业生产执行系统的软件基础设施

结合流程工业环境苛刻,生产过程复杂等特点,针对传统MES存在的环境适应性低、研发和维护成本高和应用效果不理想等问题,提出基于模型驱动架构软件开发方法的软件基础设施,用于构建下一代柔性MES。其总体目标是使MES在满足流程工业普适性需求的同时,也能适应特定的企业环境。基于层次化设计,系统分为CIM、PIM和PSM。在PIM软件基础设施之上,CIM又包括3个领域模型:功能模型分析需求并描述功能,逻辑模型使用自描述的建模方法,定义工厂对象模型、用户接口和工作流程,科学计算模型将工厂对象模型转换为数学模型,最终实现数据协调和生产优化的闭环管理。原型验证及工程实践表明,系统能够实现与传统MES相一致的领域模型,并显著缩短产品交付时间,降低项目成本。本文将领域建模过程和软件开发过程彻底分离,提高了软件抽象层次和复用度。与之前的MDA相比,系统更具运行时动态特征,领域模型能够在编译期后被方便地修改,使UML等设计工具的输出不再仅仅是文档,而成为可执行的产物。     

Development of holonic manufacturing execution systems

Rapid changes of market demands and pressures of competition require manufacturers to maintain highly flexible manufacturing systems to cope with a complex manufacturing environment. To meet these requirements, this work adopts the concepts of holon and holarchy to design manufacturing systems. Holon and holarchy are derived from the studies of social organizations and living organisms and possess the properties of intelligence, autonomy, cooperation, reconfigurability, and extensibility. Moreover, advanced manufacturing systems also require the properties of security certification and failure recovery. Based on the requirements of these properties, a systematic approach is proposed to develop a holonic manufacturing execution system (HMES) for the semiconductor industry. This systematic approach starts with a system analysis by collecting domain requirements and analyzing domain knowledge. The HMES Holarchy is designed by the procedure of constructing an abstract object model based on domain knowledge, partitioning application domain into functional holons, identifying generic parts among functional holons, developing the Generic Holon, defining holarchy messages and the holarchy framework of HMES, and finally designing functional holons based on the Generic Holon. It is believed that this proposed systematic approach provides a novel and efficient way to design HMES.     

Dynamic schedule execution in an agent based holonic manufacturing system

The present paper deals with the negotiation based task allocation to the resources for preparing dynamic scheduling in an agent based holonic control framework. The scheduling priority is developed by Multi Objective Optimization on the basis of Ratio Analysis (MOORA) technique under Fuzzy Multi Criteria Decision Making (FMCDM) environment considering several attributes. The well-known Contract Net Protocol (CNP) is followed for the purpose of task allocation by negotiation and cooperation, where message based communication is accomplished by eXtensible markup language (XML) using J2EE. Different Document Type Definitions (DTDs) are developed for intended applications. Necessary modifications in the scheduling arising out of changes in the volume-mix are made by a distributed cooperative problem-solving algorithm to meet the demand without violating the deadline. The algorithm is implemented using HTML code in front-end with Java Server Page (JSP) through Apache Tomcat 6.02 server. It is advocated that the cooperation based teamwork coupled with higher flexibility and agility is the key to success to remain unperturbed and provide reasonably good solution in the face of disturbances and stands superior to its hierarchical counterpart.     

基于k近邻变量贡献与重构理论的工业过程故障诊断

针对工业过程中发生故障时异常变量的精确识别以及如何准确建立"故障–征兆"表的问题,本文提出了一种基于k近邻(k–NN)变量贡献分析和数据重构的异常变量精确识别方法.首先,将k–NN算法中各个采样时刻的统计距离指标细化,分解为每个变量的贡献并对其进行详细分析,分别从单变量和多变量异常角度进行方法的可行性验证,确定过程故障时异常变量具有较大的贡献值;其次,建立正常数据中每个变量的贡献模型用于对故障样本中的异常变量进行"一次"识别;随后提出基于k–NN理论的数据重构算法,并从重构原理方面进行分析,验证该方法具有一定的有效性.对于故障样本,根据变量贡献分析方法求取每个变量对距离指标的贡献,"一次"识别出故障发生时所对应的异常变量或征兆;进而通过数据重构理论对故障样本中异常变量值进行重构、检测和"二次"识别,直至辨识出过程中发生异常的所有变量,并得到故障与变量之间的关系,即"故障–征兆"表.

A STEP-based manufacturing information system to share flexible manufacturing resources data

The paper describes the design and implementation of a Manufacturing Information System as a solution to share and exchange manufacturing data. The Manufacturing Information System possesses relevant features for data sharing and exchanging, that are compliant to the standard ISO 10303, known as STEP¹. It is known that manufacturing planning and execution activities require data from machine-tools, robots, ASRSs², AGVs³ and, on the other hand, computer-based applications (CAM⁴, CAPP⁵ or PAC⁶) use proprietary formats to store flexible manufacturing resources data. The way the proprietary formats are built has lead to incompatibilities and interoperability problems among the applications. It is argued that by solving these problems a qualitative functional synergy will result during manufacturing planning and execution activities. The suggested solution is using a STEP-based information system, a server and a prototype client application. These three programs are implemented in Java classes to facilitate data sharing and exchanging of flexible manufacturing resources.This revised version was published in June 2005 with corrected page numbers.
