The facility layout problem is one of the fundamental production system management problems. It has a significant impact on overall efficiency. This paper introduces new that allows for choosing from multiple variants each facility. need most suitable selection while at same time optimizing other quality indicators represents optimization challenge. We build our previous work where single- and ...

In orthogonal graph drawing, edges are represented by sequences of horizontal and vertical straight line segments. For graphs of degree at most four, this can be achieved by embedding the graph in a grid. The number of bends displayed is an important criterion for layout quality. A well-known algorithm of Tamassia eeciently embeds a planar graph with xed combinatorial embedding and vertex degre...

one of the most important issues in the plant layout design especially in mass production organizations with high inter-plant logistics is‘material flow and inter-plant traffic analysis and its effects on the production capabilities or pauses in production lines. in this paper the inter-plant traffic analysis issue on the basis of single channel queue model (m/m/1) is analyzed in a carmaker c...

A hybrid network is proposed in dynamic CMOS XOR/XNOR gate to avoid signal skew and reduce the power consumption. Compared to the standard N type dynamic gate leakage power, dynamic power and layout area of the novel XOR/XNOR gate are reduced. In this paper we studied different technologies, their merits and demerits. Comparison of different technologies is completely on the basis of leakage po...

The sewer layout in flat areas significantly influences the construction and operational costs as well as reliability of the network performance. To find an optimum design of sewer networks for flat areas, this study presents a multi-objective optimization problem with the objective functions of 1- the cost and 2- the reliability. The reliability criterion is defined as the effect of a clogging...
