The double row layout problem (DRLP) seeks to determine optimal machine locations on either side of an aisle, where the objective has been defined as the minimization of material flow cost among machines while meeting machine clearance constraints. In this paper, we extend existing DRLP formulations in two respects. First, we consider the minimization of layout area besides the usual material f...

This paper is the 3rd in a series of papers discussing characterization of a Micro-Electrical-Mechanical-System (MEMS) deformable mirror in adaptive optics. Here we present a comparison between a conventional adaptive optics system using a Xinetics continuous face sheet deformable mirror with that of segmented MEMS deformable mirror. We intentionally designed the optical layout to mimic that of...

Several industrial problems involve placing objects into a container without overlap, with the goal of minimizing a certain objective function. This problems arise in many industrial fields such as apparel manufacturing, sheet metal layout, shoe manufacturing, VLSI layout, furniture layout, etc., and are known by a variety of names: layout, packing, nesting, loading, placement, marker making, e...

Diagram-based visual languages are an established means for describing and developing software systems, but have an important drawback: users need to place diagram elements properly for a diagram to be properly readable, which can take a significant amount of time (Klauske and Dziobek 2010). Automatic layout algorithms aim to automate that task to improve user productivity. These algorithms ena...

In layout problem of manufacturing cells, rectangular cells to be positioned without overlapping. The objective is to minimize the total transportation cost. The types of layouts are categorized according to the shape of the transportation system’s track. In the case of a closed loop layout, the track has a rectangular shape. A common difficulty of all layout problems is the manner in which dis...
