In this paper, issues of storage layout and order picking operations problems for warehousing are addressed using optimization techniques. The aim of this study is to develop a dynamic planning system applied for storage layout and order-picking operations problems. The planning system considers dynamic nature of customer order demand, configuration of picking area, and interactive human-machi...

As the VLSI feature size has already decreased below lithographic wavelength, the printability problem due to strong diffraction effects poses a serious threat to the progress of VLSI technology. A circuit layout with poor printability implies that it is difficult to make the printed features on wafers follow designed shapes without distortions. The development of Resolution Enhancement Techniq...

This paper deals with the handling of deformable linear objects (DLOs), such as hoses, wires or leaf springs, bases on force/torque sensing. First, we describe the characteristic change of force and moment for all single-contact transitions which may occur between DLO and a rigid polyhedron obstacle. Second, we present data processing algorithms for the automated detection of state transitions ...

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 paper introduces performance aspects as a new optimization criteria when generating Gate Matrix Layouts. A new layout model is presented that limits the amount o f parasitic capacitance in signal paths and the resistance in power supply lines. The performance considerations are combined with a new layout s-trate g y that improves circuit performance with little or no area penalty. A n Auto...

Parallel Layout Engines: Synthesis and Optimization of Tree Traversals

LayOPTTM is an innovative facilities layout analysis and optimization software package which can be used by layout planners and engineers in the optimal solution of single and multiple floor facility layout problems. LayOPT is ideal for the re-design of the overall layout for an existing facility or the development of a block layout for a new building. It can be applied to manufacturing, wareho...
