Grouping the machines and parts in a cellular manufacturing system based on similarities is known as the cell formation. This paper proposes a method for design of cell layout for a manufacturing system under dynamic demand environment for automation batch production industry. The proposed method of cell layout has two phases. In the first phase, Rank Order Clustering (ROC) was used to determin...

in the present paper, we develop a modified pseudospectral scheme for solving an optimal control problem which is governed by a switched dynamical system. many real-world processes such as chemical processes, automotive systems and manufacturing processes can be modeled as such systems. for this purpose, we replace the problem with an alternative optimal control problem in which the switching t...

Small and medium size enterprises (SMEs) have gained competitive advantage by using Just-in-Time, Total Quality Management, and Information Technology. Cellular Manufacturing (CM) has received less attention from SMEs. This paper reports the findings of a case study of the application of Group Technology in an SME. A framework for the design and implementation of Cellular Manufacturing Systems ...

this paper deals with the problem of optimizing two-stage structure decision making units (dmus) where the activity and the performance of two-stage dmu in one period effect on its efficiency in the next period. to evaluate such systems the effect of activities in one period on ones in the next term must be considered. to do so, we propose a dynamic dea approach to measure the performance of su...

Cellular manufacturing systems are widely used due to their advantageous capability of combining the flexibility job-shop and productivity flow-shop. In recent years, reduction product life cycle, variation in demand products, introduction new technologies, have driven companies improve responsiveness, thus reducing cellular cycle with a focus on re-designing cells. Another issue concerns susta...
