The advantages of contemporary communication and information technologies based on virtual reality techniques offer for companies a totally new approach to cooperation. Use of virtual product models can be extended to product development, manufacturing, marketing, customization and selling of products for Internet based virtual enterprises. The presentation addresses how the virtual product mod...

Given the growing evolution of technology, machinery and manufacturing techniques, conventional methodologies for training the workforce are not enough for the current needs. Therefore methodologies capable to accelerate the training process and able to train the trainee in a wide range of scenarios are claimed for the industrial sector. Virtual reality offers an alternative that has been succe...

Manufacturing is using Virtual Reality tools to enhance the product life cycle. Their definitions are still in flux and it is necessary to define their connections. Thus, firstly, we will introduce more closely some definitions where we will show that, if the Virtual manufacturing concepts originate from machining operations and evolve in this manufacturing area, lots of applications exist in d...

Since the part design process is mainly based on constrains like geometry and function, a static optimization approach can be used. Corresponding optimizing algorithms would yield appropriate values for the part and its function. A more complex situation takes place in the manufacturing and assembly processes: their complex functions are time dependant and may run in a variety of logical arrays...

Virtual cellular manufacturing systems (VCMS) have come into existence, replacing traditional cellular manufacturing systems (CMS), to meet highly dynamic production conditions in terms of demand, processing times, product mix and processing sequence. While cell formation phase of VCMS has been dealt quite voluminously, worker assignments phase has gained momentum recently after researchers sta...

Virtual factory (VF) can provide a total solution for shortening manufacturing cycle time and achieving customer satisfactions. Hence, many world-class companies dedicate themselves to establish their own virtual factories. However, it is di€ficult to implement a virtual factory because of the lack of assistant tools. A three-tier architecture based colored timed Petri net emulator is developed...

Transformations in the marketplace have led manufacturing companies to focus on their core competences and compete through new forms of enterprise partnerships. A new concept of enterprise partnership is that of Virtual Enterprise wherein autonomous or independent companies come together to temporally address a specific market demand, by collaborating closely and presenting to the market as a s...

Virtualization is critical for resource sharing and dynamic allocation in cloud manufacturing, a new service-oriented networked collaborative manufacturing model. In this paper, an effective method is proposed for manufacturing resources & capabilities virtualization, which contains manufacturing resources modeling and manufacturing cloud services encapsulation. A manufacturing resource virtual...
