The layout design problem is a strategic issue and has a significant impact on the efficiency of a manufacturing system. Much of the existing layout design literature that uses a surrogate function for flow distance or for simplified objectives may be entrapped into local optimum; and subsequently lead to a poor layout design due to the multiple-attribute decision making (MADM) nature of a layo...

  A fuzzy goal programming-based approach is used to solve a proposed multi-objective linear programming model and simultaneously handle two important problems in cellular manufacturing systems, viz. cell formation and layout design. Considerations of intra-cell layout, the intra-cell material handling can be calculated exactly. The advantages of the proposed model are considering machining cos...

An efficient method for size and layout optimization of the truss structures is presented in this paper. In order to this, an efficient method by combining an improved discrete particle swarm optimization (IDPSO) and method of moving asymptotes (MMA) is proposed. In the hybrid of IDPSO and MMA, the nodal coordinates defining the layout of the structure are optimized with MMA, and afterwards the...

Quality and value of an IC product are functions of power, performance, area, cost and reliability. The forthcoming 2013 ITRS roadmap observes that while manufacturers continue to enable potential Moore’s Law scaling of layout densities, the “realizable” scaling in competitive products has for some years been significantly less. In this paper, we consider aspects of the question, “To what exten...

This paper presents a layout generation tool that aims to reduce the gap between electrical sizing and physical realization of high performance analog circuits. The procedural layout approach is shown to be best suited for this kind of methodologies. Once captured, the procedural description can be used several times to calculate both rapidly and accurately all parasitics that appear during phy...

Micromachining techniques are being increasingly used to develop miniaturized sensor and actuator systems. These system designs tend to be captured as layout, requiring extraction of the equivalent microelectromechanical circuit as a necessary step for design verification. This paper presents an extraction methodology to (re-)construct a circuit schematic representation from the layout, enablin...

The common Arabic keyboard layout is derived from the Arabic typewriter keyboard’s layout. This layout is not optimized for typing speed and has several problems. We use a genetic algorithm to optimize the design of the Arabic keyboard layout for typing speed. In the genetic algorithm, we use a fitness function that includes into consideration key distance, finger used, and hand alternation. We...

This article provides a case study for a fire extinguisher manufacturing company in North America that has been building a new facility in Mexico to benefit from North America Free Trade Agreement (NAFTA) and low production cost. The company utilized a value stream mapping to finalize its new facility’s manufacturing process design, and divided the process into several groups, some of which wer...

The paper discusses the adaptation and width definition methods of a content-driven template based layout system. The approach supports online magazine editors to design magazine layouts. Based on the layouts the approach automatically adapts the actual content to different device screens. In this paper we introduce the concept of the Vertical Splitter Component and discuss the related layout d...

Modern integrated circuits (IC) operate in environment of various destabilizing factors which have essential influence on the operation of these circuits and often even disturb the normal operation. One of these destabilizing factors is the cosmic radiation, particularly total ionization dose effects (TID). For modern TID tolerant ICs [1-4] design is being done by circuit designers. In this pap...
