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...

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...

The application of group technology to production systems has in many firms led to the introduction of cellular manufacturing. This paper studies the changes that are required in the organization of the planning and control systems when applying cellular manufacturing. We review existing frameworks for designing such a planning and control system and propose a new framework that gives attention...

Cellular Manufacturing System (CMS) is an application of Group Technology (GT) that allows decomposing a manufacturing system into subsystems. Grouping the machines and parts in a cellular manufacturing system, based on similarities is known as cell formation problem (CFP) which is an NP-hard problem. In this paper, a mathematical model is proposed for CFP and is solved using the Ant Colony Opt...
