A facility layout problem is concerned with determining the best position of departments, cells, or machines on the plant. An efficient layout contributes to the overall efficiency of operations. It’s been proved that, when system characteristics change, it can cause a significant increase in material handling cost. Consequently, the efficiency of the current layout decreases or is lost and it ...

Many engineering disciplines require visualisation of networks. Constrained graph layout is a powerful new approach to network layout that allows the user to impose a wide variety application-specific placement constraints—such as downwards pointing directed edges, alignment of nodes, cluster containment and non-overlapping nodes and clusters—on the layout. We have recently developed an efficie...

The rapid development of exible, layout independent web sites is an increasingly important problem. Flexibility, scalability and the ability to adapt to evolving layout requirements is a key success factor for many web sites. A fundamental way to meet these requirements is to strictly separate business logic from the layout and the content. The World Wide Web Consortium's XML and XSL standards ...

In many application domains there is a strong need to produce content both for traditional print media and for interactive media. In order to fully benefit from digital devices, online documents must provide mechanisms to support interactivity and for the personalization of content. Thus, powerful authoring tools as well as flexible layout techniques are needed to display dynamic information ef...

In this paper we introduce two novel algorithms for drawing sequences of orthogonal and hierarchical graphs while preserving the mental map. Both algorithms can be parameterized to trade layout quality for dynamic stability. In particular, we had to develop new metrics which work upon the intermediate results of layout phases. We discuss some properties of the resulting animations by means of e...

Researchers in the area of automated design of user interfaces have shown that the layout of an interface can, in many cases, be generated from the application’s data model using an intelligent program that applies design rules. The specification of interface behavior, however, has not been automated in the same manner, and is mostly a programmatic task. Mecano is a model-based user-interface d...

Dynamic application layout is the capability to move the components of a distributed program among different hosts during the execution of the application. This capability is essential for large-scale applications since it allows to adapt them to changes in resource availability, which are common in wide-area environments. The FarGo system introduces a model for programming the layout of distri...

Many classical graph visualization algorithms have already been developed over the past decades. However, these algorithms face difficulties in practice, such as the overlapping node problem, large graph layout and dynamic graph layout. In order to solve these problems, this paper aims to systematically address algorithmic issues related to a novel framework that describes the process of graph ...
