Due to the competitive nature of market and various products production requirements with short life cycles, cellular manufacturing systems have found a special role in environments. Creativity innovation are results mental effort workforces addition machinery parts allocation. Assignment workforce cells based on interest ability indices is tactical decision while cell formation strategic decis...

Virtual Cellular Manufacturing Systems (VCMSs) are based on a highly flexible manufacturing concept designed to improve the performance of classical Cellular Manufacturing Systems (CMSs) and job shop manufacturing environments by creating virtual grouping of the resources temporarily in the production planning and control system. In an environment with fluctuating demand and unpredictable parts...

A new mathematical model based on the alternative process routings in presence of a queuing system in a dynamic cellular manufacturing system has been proposed in this paper.This model integrates two problems of cell formation and inter-cell layout and also an efficiency factor which is defined for minimizing the cell load variation through the maximizing the busy time for all machine types. In...

New environmental characteristics and requirements have challenged manufacturing enterprises to improve the efficiency and productivity of their production activities. Cellular manufacturing (CM) as one of the solutions to this problem, as implementation of Group technology (GT), was proposed. Performance of cellular manufacturing systems depends heavily on the cell structure. In this paper we ...

In today’s markets, non-uniform, customized products complicate the manufacturing processes significantly. In this paper, we propose a cellular manufacturing system design model to manage product variety by integrating with the technology selection decision. The proposed model determines the product families and machine groups while deciding the technology of each cell individually. Hedging aga...

Next Generation Manufacturing Systems (NGMS) will support the Next Generation Manufacturing Enterprises (NGMEs). Adaptive distributed manufacturing systems seem to be a promising solution for NGMEs to provide increased levels of flexibility, reconfigurability and intelligence to respond to the highly dynamic market demands. Virtual Enterprises (VEs) are expected to be the dominant manufacturing...

during the recent decades, substantial changes are made in the borders and contents of physiology as a basic course for the students in medicine. here some strategies are presented to preserve the classical and integrative approaches in teaching physiology, while these approaches extent our knowledge to molecular, sub-cellular and cellular levels.

Agent-based technologies can be applied to many aspects of manufacturing. The need for responsive, flexible agents is pervasive in manufacturing environments due to the complex, dynamic nature of manufacturing problems. Two critical aspects of agent capabilities are the ability to: (1) classify agent behaviors according to autonomy level, and (2) adapt problem-solving roles to various problem-s...
