Manufacturing industry worldwide has been facing unprecedented challenges brought by global competition and rapidly customer requirements which cause major changes in the production style and configuration of manufacturing enterprises. Networked Manufacturing enables rapid and efficient product development by equipment sharing which is a key component of networked manufacturing platform. The problems of poor transparency and low efficiency that the traditional way of equipment sharing faces, effectively overcome by leveraging the Internet, This paper proposes architecture for equipment sharing over the networked manufacturing platform involving the layer of resource sharing and the cooperative layer. An experimental case study has been carried out in a firm in the die-casting industry in order to demonstrate the features and the potential industrial application of the equipment sharing systems outlined in the current paper.

The design of the information system of manufacturing companies is a crucial endeavor in implementing a successful computer integrated manufacturing environment. The complexity of the manufacturing environment dictates the need for a systematic and structured approach to enable manufacturing system engineers to analyze and define their information requirement. Virtual reality based requirement analysis tool (VR-RA) has been developed for an existing novel methodology, in order to capture and represents the approach of experienced analyst studying the enterprise wide CIM information requirements. This paper introduces the methodology and describes the operational aspects of VR-RA, which is a user-friendly tool that can be used by people with little prior computer experience for the establishment of requirements.
