Today’s businesses continually search for ways to increase productivity. To achieve this goal, shorter product development cycles and shorter manufacturing times are required. In both cases, problems that may arise during development must be identified much faster. In product development, this is done using virtual prototypes that can be easily duplicated and shared between everyone involved. I...

Cellular manufacturing systems are used when both production volume and product variety are at medium level. The fluctuations of volume and mix can reduce drastically the performance of classical cellular manufacturing systems. Therefore, several configurations have been proposed in literature as virtual manufacturing cells, fractal cells and remainder cells. This paper investigates the cell lo...

in this paper, we present a simulated annealing (sa) and a genetic algorithm (ga) based on heuristics for scheduling problem of jobs in virtual cellular manufacturing systems. a virtual manufacturing cell (vmc) is a group of resources that is dedicated to the manufacturing of a part family. although this grouping is not reflected in the physical structure of the manufacturing system, but machin...

Virtual manufacturing enterprises (VMEs) are a current, viable, and strategic form of organization for business and other organizations. The perspectives described in this literature review are based upon a basic cluster analysis that identified and classified papers into homogenous subgroups with meaningful themes, or categories. These general themes are related to strategies for business orga...

This paper presents news problems linked to the increasing use of virtual spaces in the building of new types of manufacturing what is currently called Virtual Manufacturing (VM). VM has many consequences in the activity of industrial companies whatever be size, economic sector or geographical area. Particular attention is paid on virtual spaces, manufacturing and collaboration, skills matrix a...

Augmented and Virtual Reality technologies are increasingly being used in manufacturing processes. These use real and simulated objects to create a simulated environment that can be used to enhance the design and manufacturing processes. Virtual and Augmented Realty Applications in Manufacturing is written by experts from the world's leading institutions working in virtual manufacturing and giv...

Companies and firms, nowadays, due to mounting competition and product diversity, seek to apply virtual cellular manufacturing systems to reduce production costs and improve quality of the products. In addition, as a result of rapid advancement of technology and the reduction of product life cycle, production systems have turned towards dynamic production environments. Dynamic cellular manufact...

A virtual factory integrated manufacturing system combined with system simulation and virtual reality is introduced in this paper. We describe the system architecture and development methodology, provide the working principle of process simulation and monitoring in virtual factory, and then explain the detailed applications of virtual factory integrated manufacturing system. With the visualizat...
