This paper presents a mathematical model for designing cellular manufacturing systems (CMSs) solved by genetic algorithms. This model assumes a dynamic production, a stochastic demand, routing flexibility, and machine flexibility. CMS is an application of group technology (GT) for clustering parts and machines by means of their operational and / or apparent form similarity in different aspects ...

In order to implement the cellular manufacturing system in practice, some essential factors should be taken into account. In this paper, a new mathematical model for cellular manufacturing system considering different production factors including alternative process routings and machine reliability with stochastic arrival and service times in a dynamic environment is proposed. Also because of t...

Cellular manufacturing emerged as a production strategy capable of solving the problems of complexity and long manufacturing lead times in batch production. The fundamental problem in cellular manufacturing is the formation of product families and machine cells. This paper presents a new approach for obtaining simultaneous arrangement of part families and machine cells for cellular manufacturin...

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 ...

There are essentially two ways to implement a Cellular Manufacturing System (CMS): physical and logical. In the first case, the machines are laid out in the floor space in dedicated manufacturing cells to exploit flow shop efficiency in processing part families, whereas in the second case machines are dedicated to process part families in a process layout. Logical oriented CMS are known as Virt...

Cellular manufacturing (CM) is one of the most important subfields in the design of manufacturing systems. As a recently emerged field of study and practice, virtual cellular manufacturing (VCM) is of enormous importance as one of the types of CM . One kind of VCM problems is VCM with alternative processing routes from which the route for processing each part should be selected. In this study, ...

the cellular automata method has been used to simulate the pattern formation of the schlögl model as a bistable reaction-diffusion system. both microscopic and macroscopic cellular automata approaches have been considered and two different methods for obtaining the probabilities in the microscopic approach have been mentioned. the results show the tendency of the system towards the more stable ...

Cells are composed of macromolecular structures of various sizes that act individually or collectively to maintain their viability and perform their function within the organism. This review focuses on one structure, the microtubule, and one of the motor proteins that move along it, conventional kinesin (kinesin 1). Recent work on the cellular functions of kinesins, such as the organization of ...

In this research, computer simulation is used for Electronic Manufacturing Service (EMS) plant layout analysis. The current layout of this manufacturing plant is a process layout, which is not suitable due to the nature of an EMS that has high-volume and high-variety environment. Moreover, quick response and high flexibility are also needed. Then, cellular manufacturing layout design was determ...
