An evaluation framework for deploying Web Services in the next generation manufacturing enterprise

In today's competitive manufacturing environment, the ability to effectively and efficiently manage the flow of information is a vital competency. Manufacturing enterprises must be able to integrate their internal business processes horizontally and vertically, and they are increasingly required to support federated business processes with other members of their respective virtual value chains. Web Services, an emerging form of service-oriented architecture for distributed computing, have the potential to serve as a key enabling technology to support these requirements. Leveraging the inherent interoperability of Internet and Worldwide Web technologies, they enable cooperative processing across heterogeneous computing environments. This paper presents a framework for evaluating the viability of Web Services technologies to be incorporated into enterprise information architectures to support the business needs and requirements of next generation manufacturing enterprises. It examines economic, technical, and organizational contexts that will influence the ability of manufacturing-related enterprises to deploy advanced information architectures based on Web Services to support the complex business processes needed to collaborate with suppliers, customers, and other stakeholders in virtual enterprise environments.

VirtuE: a formal model of virtual enterprises for information markets

A vital part of a modern economy is an information market. In this market, information products are being traded in countless ways. Information is bought, modified, integrated, incorporated into other products, and then sold again. Often, the manufacturing of an information product requires the collaboration of several participants. A virtual enterprise is a community of business entities that collaborate on the manufacturing of complex products. This collaboration is often ad hoc, for a specific product only, after which the virtual enterprise may dismantle. The virtual enterprise paradigm is particularly appealing for modeling collaborations for manufacturing information products, and in this paper we present a new model, called VirtuE, for modeling such activities. VirtuE has three principal components. First, it defines a distributed infrastructure with concepts such as members, products, inventories, and production plans. Second, it defines transactions among members, to enable collaborative production of complex products. Finally, it provides means for the instrumentation of enterprises, to measure their performance and to govern their behavior.     

A standard manufacturing information model to support design for manufacturing in virtual enterprises

Manufacturing enterprises are being forced into greater collaboration with customers and suppliers in order to produce quality products in smaller batches, shorter lead times and with greater variety. Consequently, the design-for-manufacturing task must be conducted in these virtual and distributed enterprises across traditional organizational boundaries. This paper proposes the use of standard information models to support the product realization process. While extensive work has been performed in developing product data models little effort has been performed in developing a manufacturing model. The design-for-manufacturing stages are identified with their requisite information requirements. Different approaches used to model various aspects of manufacturing processes are reviewed and found inadequate for supporting the entire design-for-manufacturing task. The development of a standard manufacturing systems information model written in EXPRESS and based upon the modelling me thodology adhered to by standard for the exchange of product (STEP) is proposed to fill the void. Initial developments in this area are discussed, the model is illustrated with an example, and the potential benefits to manufacturing are reviewed.     

RFID-enabled real-time manufacturing information tracking infrastructure for extended enterprises

In extended enterprises, real-time manufacturing information tracking plays an important role and aims to provide the right information to the right person at the right time in the right format to achieve optimal production management among the involved enterprises. However, many enterprises are caused by lack of timely, accurate and consistent manufacturing data. The laggard information transfer flow and the unmatched information transfer method bring extended enterprises much more uncertainty and unknowingness. This paper proposes a RFID-enabled real-time manufacturing information tracking infrastructure (RTMITI) to address the real-time manufacturing data capturing and manufacturing information processing methods for extended enterprises. Following the proposed infrastructure, the traditional manufacturing resources such as employees, machines and materials are equipped with RFID devices (Readers and Tags) to build the real-time data capturing environment. In addition, a series of manufacturing information processing methods are established to calculate and track the real-time manufacturing information such as real-time manufacturing cost, progress, WIP (Work-in-progress) inventory etc. in parts/assemblies/products at machines/shop floors/enterprises/ extended enterprises levels. Finally, a case study is given to demonstrate the developed framework and corresponding methodologies.
