the dynamic facility layout problem (dflp) is the problem of finding positions of departments onthe plant floor for multiple periods (material flows between departments change during the planning horizon)such that departments do not overlap, and the sum of the material handling and rearrangement costs isminimized. in this paper a new optimization algorithm inspired from colonizing weeds, invasi...

• An ANN-based generative design method is proposed for layout/material design. The integrates GAN, CNN and genetic algorithm to form a general approach. adaptive learning optimization strategy proposed, allowing optimal solutions be found efficiently. Excellent performance of the demonstrated on two heat source layout problems. Comparison with existing methods conducted. Layout designs are enc...

This paper contributes to two different areas: (1) layout problems and (2) integer programming. (1) One important class of layout problems arises when rectangles are to be placed on the plane. The rectangles represent machines with their close environments or small production cells. There is a flow of the semi-finished products among the rectangles. The problem is to place the rectangles withou...

When a printed document is to be input to a computer system, the document must be converted to a computer-readable format, e.g., ASCII, PDF, RTF, CSV, or SGML/XML/HTML-tagged data. In order to obtain these data formats from a printed document, it is necessary to extract from the printed document as much information as possible, i.e., layout structure (layout objects and their hierarchical relat...

The optimization of water distribution networks are complex, multi-modal and discretevariable problems that cannot be easily solved with conventional optimization algorithms. Hence, evolutionary techniques such as genetic algorithms and simulated annealing have been extensively employed during the last decade. This study adopts a Tabu search (TS), which is an evolutionary method based on explic...

The layout design problem is a kind of nesting problems that is naturally NP-hard and very difficult to solve. Layout designing of machine is even more difficult because of its nesting items are actually machine parts that have both irregular shapes and complex constraints. A feasible way to solve machine layout problem is to employ ameliorative algorithms, such as simulated annealing algorithm...

Increasing global competition has enforced all members of supply chains to optimize their activities to achieve high performance and customer satisfaction. A company can improve its supply chain performance in terms of responsiveness and efficiency by means of good facility layout design. Facilities are the places in the supply chain network where product is stored, manufactured, assembled or f...
