Constrained graph layout is a recent generalisation of forcedirected graph layout which allows constraints on node placement. We give a constrained graph layout algorithm that takes an initial feasible layout and improves it while preserving the topology of the initial layout. The algorithm supports poly-line connectors and clusters. During layout the connectors and cluster boundaries act like ...

This paper presents a multi-objective mixed-integer nonlinear programming model to design a group layout of a cellular manufacturing system in a dynamic environment, in which the number of cells to be formed is variable. Cell formation (CF) and group layout (GL) are concurrently made in a dynamic environment by the integrated model, which incorporates with an extensive coverage of important ...

According to [1], the material handling cost comprises about 20-50% of the total operating cost of the facility layout. Typical research on facility layout concentrate on static layout problems where from-to charts are used to evaluate the layout. These layouts are not flexible enough to accommodate any future changes in production. Research on dynamic facility layout also has used the concept ...

This paper proposes a modified spring modeling algorithm for drawing undirected graphs, that is an extension of the forceddirected placement method of spring modeling algorithm by Eades. We call it dynamic parameter spring modeling algorithm. This algorithm is not only a general algorithm for graph layout, but also it is more suitable to get a semi-stable graph layout. A semi-stable layout is a...

Grouping the machines and parts in a cellular manufacturing system based on similarities is known as the cell formation. This paper proposes a method for design of cell layout for a manufacturing system under dynamic demand environment for automation batch production industry. The proposed method of cell layout has two phases. In the first phase, Rank Order Clustering (ROC) was used to determin...

This paper proposes a novel user interface to manage the dynamic layout of multimedia objects in the Multimedia Bulletin Board (MBB) system. The MBB has been designed and implemented as a prototype of an asynchronous communication system that enables rich communication and collaboration among users of multimedia objects such as text, image, moving picture, sound, voice, web, office document, an...

Layout plays crucial role in readability and interpretation of presentations. This holds also for online presentations, where automated layout generation is needed to deal with dynamic presentation contents and changing presentation contexts. In this paper, we present the DesignComposer prototype, an automated layout generator for web pages. It uses different AI approaches and a declarative rep...
