Circuit design in deep sub-micron technologies requires that designers deal with numerous data, constraints, analysis, synthesis, and optimization tools. Although synthesis tools are widely used at Intel, new circuit technologies are evolving and are often not well supported by existing synthesis tools. Deep sub-micron technology requires that the impact of physical design be considered early i...

The indispensable vital structure in any harbor is a breakwater in order to make available calm water region inshore. Pile breakwater can be employed as a small coastal protection structure where tranquility required is low. This study is concerned with CFD study on the performance of perforated hollow pile to dissipate wave energy and the novelty of this investigation is the role of perforatio...

This paper presents an integrated design approach for the facility layout problem. It develops a method for the concurrent determination of the block layout, the locations of departmental input and output (I/O) points using the contour distances between the I/O points, and the material flow paths between the I/O points. Results of computational experiments show that the performance of this inte...

Group technology is a manufacturing philosophy that attempts to provide some of the operational advantages of a line layout while maintaining some of the strategic advantages of the job shop layout. In designing a productive process that will adopt this manufacturing strategy, one of the primary problems encountered is the formation of component families and production cells. The production cel...

Each reduction of the technology node has, along with improvements in IC fabrication technology, been the main driver in delivering the demand for function rich, integrated mobile electronics that are so prevalent. As devices keep growing smaller and geometries approach the order of a few atomic layers, it is increasingly difficult to achieve cost-effective mass production for reasons related t...

there are some problems with estimating the time required for the manufacturing process of products, especially when there is a variable serving time, like control stage. these problems will cause overestimation of process time. layout constraints, reworking constraints and inflexible product schedule in multi product lines need a precise planning to reduce volume in particular situation of lin...

KCSS 2015/2 M ro Sönem nn Automatic layout is an important tool for the efficient use of graphical models in a model-driven engineering (MDE) context. Since the 1980s, research on graph layout methods has led to a multitude of different approaches, and several free software libraries for graph layout are available. However, today’s practically relevant MDE tools hardly reflect this diversity. T...

When workflow congestion is prevalent, minimizing total expected material handling time is more appropriate than minimizing a distanced-based objective in manufacturing facility layout design. We present a model labeled Full Assignment Problem with Congestion (FAPC), which simultaneously optimizes the layout and flow routing. FAPC is a generalization of the Quadratic Assignment Problem (QAP), a...
