Developing an agent-based APS and ERP collaboration framework

In order to respond rapidly to customer demand, SCM and ERP have been widely implemented in business. However, SCM was designed as a planning level tool to support business making related activities. For instance, the advanced planning system (APS) was aimed at developing a proper production schedule to support the potential orders. On the other hand, ERP was used in the execution level in an enterprise to integrate the order execution related business process. In order to integrate the two systems, there were several gaps exists such as the suitability of using the APS results in the ERP. In this research, an integrated APS and ERP framework will be proposed to support the collaboration among these systems. It applies the concept of Web service and agent collaboration to support the issues such as workflow integration and collaboration encountered during the integration period. There are three main stages in this framework. In the business analyze stage, the collaboration process among the APS and ERP will be analyzed and constructed by using eEPC (extended event process chain) modeling method. This result will be used in the next stage, the business design stage to design the agent-based collaboration system. A workflow oriented agent-based analyzed method, WARP (workflow automation through agent-based reflective processes) will be used to analyzed the collaboration business process and construct the related agents. Finally, in the implementation level, the related agents will be constructed by integrating i2 FP SCM modules and DataSystem Workflow ERP under the Web-based environment.

Integration technology of ERP and PDM based on business remote function call

In order to better support ERP system and PDM system integration for independent enterprise network manufacturing systems, the characteristics of ERP and PDM integration are analyzed and the technology of business remote function call is presented. The standards or custom functions which support remote transfer using BRFC interface could be called by ERP and PDM systems. The data gained by ERP and PDM systems can be used to achieve the integration. Not only can a kind of integration model of ERP and PDM be composed, but the RFC interface can be semantically described. The structure, realization and interview of remote function call technology, which are used by ERP and PDM integration, are researched. Also, data exchange of system integration based on data stream direction is discussed to illustrate self-containment, collaboration and recombination of the ERP and PDM systems integration. The conception of a heterogeneous data translator is put forward, and its data structure is given. Interface development tools provided by ERP and PDM are fully considered. The system composing mode is construed clearly. The heterogeneous data translator is applied to realize classic code systems, system information searches of PDM, system information searches of ERP and integration information searches. Then the advantages of BRFC are expounded. The effectiveness and suitability of the BRFC interface integration mechanism is explained and verified. Finally, two application examples are presented to verify the feasibility and efficiency of RFC technology: a typical integration of WLPDM and SAP R/3 ERP in WLNM networked manufacturing platform and a typical integration of Kingdee ERP and HTPDM in Haitian mass customization platform. Thus seamless integration, plain integration, non-repeated data memory, integration flexibility and low cost are realized.

Development of a prototype customer-oriented virtual factory system

Current Computer integrated manufacturing/Enterprise Resource Planning (CIM/ERP) systems require harmony and communication between humans and facilities. A user’s preferences should also be considered in CIM/ERP systems. Virtual factory (VF), also known as virtual manufacturing (VM), systems can fulfill the requirements of current CIM/ERP systems. A VF system simulates virtual production in a virtual factory environment on the computer system which allows optimization prior to going into production. In this paper, we defined a VF system as a pre-analyzing system for designing, engineering and manufacturing a product in the enterprise system of the real world. The objective of this paper is to design a VF system and to develop a prototype system that the customer can participate in and be satisfied with. We selected a telephone as a sample product for the VF system. The VF system consists of four subsystems: virtual product ordering, design, manufacturing, and CIM/ERP interface. The prototype system aims to develop a virtual product ordering and design system.

A component-based product data management system

Companies today have been attempting to expand their Internet infrastructures to cope with the growth of global business environments. In modern manufacturing industries, they are migrating their legacy product data management (PDM) systems to Web-based systems (being an essential tool of eManufacturing) to use the Internet. Accordingly, recent advances in PDM technology have dealt with the use of Web-based technology. Some research and development on Web-based PDM systems has been described in the literature, but those efforts have technical limits. They are not adequately available, secure, reliable, and scalable for global enterprise services. This paper describes the design of a component-based product data management (CPDM) system for supporting global manufacturing. The CPDM system is aimed at assuring flexibility, security, stability, and maintainability by utilizing a standard architecture of J2EE technology. The CPDM system consists of three tiers based on the J2EE architecture. The first is the presentation tier implemented as JSP/servlet components to allow users to access the system through a Web browser. The second is the business logic tier, which is implemented as Enterprise JavaBeans (EJB) components to handle the core PDM functionality. The third level is the data tier, composed of a database and vault for the physical files. To develop the components of the CPDM system, a component-based development (CBD) approach is proposed. The associated component development procedure is illustrated with examples. The CPDM system is also tested for its performance.

PDM and ERP integration methodology using digital manufacturing to support global manufacturing

Global manufacturing companies must implement manufacturing engineering with proper consideration given to the manufacturing process and resources that are appropriate for the particularities of each manufacturing site. Particularly for effective enterprise resource planning (ERP) system implementation under a global manufacturing environment, the product data management (PDM) integration for product data is one of the important keys to success. For such product data integration, engineering bill of materials (EBOM) needs to be transformed to manufacturing bill of materials (MBOM), but the MBOM transformation must be done in such a way as to fit the particularities of each manufacturing site. In this process, a methodology appropriate for integration and transformation is required. This paper proposes digital manufacturing as the key tool of data integration between PDM and ERP. Digital manufacturing, as a technology possessing the physical and logical computer modeling and simulation technique for actual manufacturing, provides the methodology for transforming EBOM to MBOM that fits the particularities of each manufacturing site, based on the process and resource models which reflect the particularities of each manufacturing site. It also provides the methodology for MBOM verification and the process and resource model integration. Using such method, the MBOM and the process and resource data, verified and appropriate for each manufacturing site, can be sent to the ERP system.

面向表面贴装车间的制造执行系统

据不完全统计,目前我国已建成的电子电路SMT(表面贴装)生产线已达六千多条.虽然SMT生产线高度自动化,但其生产效率却不尽人意,尤其在多品种、变批量的生产行业,设备的潜能没有充分发挥出来.这种情况制约了信息技术的发展和SMT水平的提高.为此本文提出,在电子电路SMT车间建立MES(制造执行系统),通过该系统对车间的各种生产数据进行采集、分析,使其可视、可控,对生产线的作业进行排产优化,对车间的物料进行动态管理.同时,本系统还可以与企业的ERP系统、PDM系统、物流系统等集成,实现数据共享,从而提高SMT生产线的工作效率.
