A key factor for realising an Internet-based virtual manufacturing system (VMS) and virtual enterprise (VE) is how to represent
the manufacturing elements and process mechanics precisely and effectively. This paper presents methods to represent the motion
paths and operation of CNC machine tools on the Web. The method is composed of: 1. Geometrical modelling of the machine tools.
2. Kinematic modelling of the movements of machine tools. 3. Representation of the developed model in the internet infrastructure.
4. Development of a prototype Web-based virtual machine tools (WVMT). WVMT is available on the internet URL http://wvmt. postech.

As energy efficiency is one of the key essentials towards sustainability, the development of an energy-resource efficient manufacturing system is among the great challenges facing the current industry. Meanwhile, the availability of advanced technological innovation has created more complex manufacturing systems that involve a large variety of processes and machines serving different functions. To extend the limited knowledge on energy-efficient scheduling, the research presented in this paper attempts to model the production schedule at an operation process by considering the balance of energy consumption reduction in production, production work flow (productivity) and quality. An innovative systematic approach to manufacturing energy-resource efficiency is proposed with the virtual simulation as a predictive modelling enabler, which provides real-time manufacturing monitoring, virtual displays and decision-makings and consequentially an analytical and multidimensional correlation analysis on interdependent relationships among energy consumption, work flow and quality errors. The regression analysis results demonstrate positive relationships between the work flow and quality errors and the work flow and energy consumption. When production scheduling is controlled through optimization of work flow, quality errors and overall energy consumption, the energy-resource efficiency can be achieved in the production. Together, this proposed multidimensional modelling and analysis approach provides optimal conditions for the production scheduling at the manufacturing system by taking account of production quality, energy consumption and resource efficiency, which can lead to the key competitive advantages and sustainability of the system operations in the industry. 相似文献
