“…It defines VCM as a fixed physical group of machines and a dynamically changing set of machines on the shop floor, describing it much like a computer process and associated data processing. Irani et al [24] extended the definition of VCM by arguing that it allows sharing of machines with other virtual cells that produce different product families, but which have overlapping resource requirements. This definition stresses that resources need not be dedicated to a single product family, but rather serve as a pool that is available for general use.…”

A cellular manufacturing system has several advantages over conventional production methods, including reduced cycle time, less work-in-process, and cheaper setup. The manufacture of a thin-film transistor-liquid crystal display (TFT-LCD) array is a complex process that uses large machines and automated material handling systems. Consequently, the relocation of machines for the manufacture of a TFT-LCD array is unrealistic and cost prohibitive. Virtual cells can be reconfigured using production control mechanisms without physically relocating the machines. This improves the cellular manufacturing system. This is an exploratory study for the design of a virtual cell design for TFT-LCD array manufacturing. The virtual cell design is dynamically reconfigured based on the product mix changes, in order to retain the efficiency and effectiveness of the system. A practical case is used for empirical illustration. The results show that the average improvements in terms of cycle time and the level of work-in-process are 23.73 and 23.59 %, respectively. The empirical results show that the proposed methodology is successful in a practical application.

Facility layout problem is associated with the arrangement of facilities in a plant. It is a critical issue in the early stages of designing a manufacturing system because it affects the total manufacturing cost significantly. Dynamic and robust layouts are flexible enough to cope with fluctuations and uncertainties in product demands in volatile environment of flexible manufacturing systems. Since the facility layout is a hard combinatorial optimization problem, intelligent approaches are the most appropriate methods for solving the large size of this problem in reasonable computational time. In this paper, first of all, dynamic and robust layouts are surveyed. After a quick look of different mathematical models, including quadratic assignment, quadratic set covering, mixed integer programming, and graph theoretic models, the various solution methods especially intelligent approaches along with their advantages and disadvantages are surveyed. Finally, after review of hybrid algorithms, the conclusion of this paper is reported.

“…Nomden et al [10] have classified VC and introduced different fields for it. Irani et al [11] have investigated a VMC system to minimize the distance travelled by the commodity. Suresh and Meredith [12] have used a fuzzy linear programming model for creation of a workshop using the VMC approach, that is; the system was still a workshop production system, but scheduling was carried out for different cells.…”

Abstract:In this work, Ant algorithm is applied for scheduling tasks in virtual manufacturing cells (VMC). In virtual manufacturing cells, machines are randomly arranged in the workshop area. The task to be processed selects appropriate machines based on pre-determined objectives. The selection of the machinery turns into a complicated problem if there are several tasks for processing. There are a limited number of machines of any type in this workshop and the objectives are the minimization of the range of operation (sequence of tasks and starting time for each task) and the sum of the distances travelled by the entire piece. A number of standard problems were solved using the Ant algorithm in order to evaluate the efficiency of the algorithm. The results obtained show that the Ant algorithm offers good solutions in shorter times.
