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

One-dimensional homotopic compaction is defined as; In a given routable layout, a layout of minimum width is reachable by operations that can move each module horizontally as a unit, also deform lines maintaining their connections and maintain their routability. This paper exploits the nature of parallelism of this problem and introduces an efficient cellular automata algorithm for homotopic co...

The fundamental function of a cellular manufacturing system (CMS) is based on definition and recognition of a type of similarity among parts that should be produced in a planning period. Cell formation (CF) and cell layout design are two important steps in implementation of the CMS. This paper represents a new nonlinear mathematical programming model for dynamic cell formation that employs the ...

One of the well-known evolutionary algorithms inspired by biological evolution is genetic algorithm (GA) that is employed as a robust and global optimization tool to search for the best or near-optimal solution with the search space. In this paper, this algorithm is used to solve unequalsized machines (or intra-cell) layout problems considering pick-up and drop-off (input/output) points. Such p...

This mathematical model forms machine cells, optimises the costs of unassigned machines and components, designs shop floor cell layout to have minimal movement materials. The complete similarity measure algorithm cells part families in a refined form. Later, exceptional elements are eliminated optimisation by using duplication sub-contracting parts. Then is designed optimised material movements...

This paper presents a multi-objective mixed-integer nonlinear programming model to design a group layout of a cellular manufacturing system in a dynamic environment, in which the number of cells to be formed is variable. Cell formation (CF) and group layout (GL) are concurrently made in a dynamic environment by the integrated model, which incorporates with an extensive coverage of important ...

This paper proposes a document-oriented modeling concept for cellular automata (CA), which supports the simple and rapid design of a huge variety of cellular automata. This modeling concept is realized as a domain-specific modeling language derived from XML (eXtensible Markup Language). XML is in general considered as the future for internet documents and data exchange. The main concept behind ...
