This paper offers an approach that could be useful for diverse types of layout problems or even area allocation problems. By this approach there is no need to large number of discrete variables and only by few continues variables large-scale layout problems could be solved in polynomial time. This is resulted from dividing area into discrete and continuous dimensions. Also defining decision var...

This paper presents the development of an Intelligent Cavity Layout Design System (ICLDS) for multiple cavity injection moulds. The system is intended to assist mould designers in cavity layout design at concept design stage. The complexities and principles of cavity layout design as well as various dependencies in injection mould design are introduced. The knowledge in cavity layout design is ...

Building façades can feature different patterns depending on the architectural style, functionality, and size of buildings; therefore, reconstructing these be complicated. In particular, when semantic are reconstructed from point cloud data, uneven density noise make it difficult to accurately determine façade structure. When investigating layouts, Gestalt principles applied cluster visually si...

introduction: the appropriate-use optimization of the limited spaces of the iranian hospitals is believed to be a crucial step towards promoting the efficiency of these healthcare centers. the issue determining the optimization patterns of the layout of units has led to a lot of efforts by researchers as it increases the efficiency of the hospitals through patients’ improvement, changing the lo...

A previous hierarchical fault tracing method for combinational circuits which requires only CAD layout data in the CAD-linked electron beam test system is expanded as applicable to sequential circuits. The characteristics in the method remains unchanged that allows us to trace a fault hierarchically from the top level cell to the lowest primitive cell and from the primitive cell to the transist...

Metal price is one of the most important parameters in the calculation of cut- off grade. The cut- off grade has the main role in determination of mine layout. Mine layout actuates mineable reserve, mine life and economic profitability. Not considering the uncertainty in metal prices can lead to a non-optimal layout. In this paper optimum underground mine layout is determined by expected utilit...

cellular manufacturing system is one of the most important applications of group technology. design of this system involves many structural and operational issues, in which the cell formation and production planning are two important steps. in this paper, a new mathematical model is proposed for integration of cell formation and production planning problems with the aim of minimizing the overal...

In this paper, we investigated a one-dimensional compactor based on a 45°-shear line technique with jogs insertion for a cell layout. The compactor can be connected off line from current commercial layout tools, such as Tanner Pro’s L-Edit, Cadence’s Virtuoso or Springsoft’s Laker, using the CIF format. A data structure of edge-linked adjacent matrix is constructed for easy implementation in ou...
