We present an application of mosaic diagrams to the visualisation of set relations. Venn and Euler diagrams are the best known visual representations of sets and their relationships (intersections, containment or subsets, exclusion or disjointness). In recent years, alternative forms of visualisation have been proposed. Among them, linear diagrams have been shown to compare favourably to Venn a...

The challenge of improving production scheduling has inspired many different approaches. This paper examines the key contributions of three individuals: Frederick W. Taylor, who defined the key planning functions and created a planning office; Henry L. Gantt, who provided useful charts to improve scheduling decision-making, and Selmer M. Johnson, who wrote a highly influential paper on the math...

It is posited that boundary objects, as inscribed artefacts, can be thought of as forms of text. In this paper a discourse-analytic framework is employed to explore the processes of sharing knowledge across boundaries. Three discursive approaches are used to re-analyze existing contributions to the boundary objects literature. First, ‘intertextual analysis’ (Allen, 2000) is applied to Brown’s (...

The following introduces CaDaDis, an extension to the architecture-independent VISTA toolkit. CaDaDis creates visible accounts of cognitive model behavior through a set of Categorical Data Displays. It includes a standard Pert Chart showing tasks by category (or resource), a Nonstandard Pert Chart that shows the temporal dependencies, and a Gantt chart that helps show occurrences of agent event...

AutomationML is an emerging IEC standard for storing and exchanging engineering data among the heterogeneous software tools involved in the engineering of production systems. One important subset of such engineering data is the plant behavior. To make this data exchangeable, AutomationML uses the existing industry data format PLCopen XML. However, at the development stages of production systems...

We introduce an extension to an architecture-independent tool (VISTA) for creating displays of cognitive model behavior, the Categorical Data Display (CaDaDis). Our display offers several views of categorical data. It includes a standard Pert Chart showing tasks by category (or resource), a Nonstandard Pert Chart that shows the temporal dependencies, and a Gantt chart that helps show occurrence...

In this paper, we introduce LiveGantt as a novel interactive schedule visualization tool that helps users explore highly-concurrent large schedules from various perspectives. Although a Gantt chart is the most common approach to illustrate schedules, currently available Gantt chart visualization tools suffer from limited scalability and lack of interactions. LiveGantt is built with newly design...

The contribution presents an application of information visualization techniques in emergency medical services process analysis. We used a novel combination of simulation approach and geographical information system technologies to model and present large volumes of different kinds of information. The suggested methodology was used to evaluate system readiness for a major incident and the capab...
