Hardware and software requirements

Disk space

Full installation of QGeNIe requires less than 20 MB of disk space.

Memory

QGeNIe has practically no minimum memory requirements and can run under a minimum Windows configuration. The actual memory requirement will depend on the size and complexity of the models that you create. Too little memory may result in decreased performance. In general, conditional probability tables grow exponentially with the number of parents of a node. The maximum number of parents of a node will, therefore, determine memory requirements. In addition, memory requirements of the clustering algorithm grow with the connectivity of the network.

Operating system

QGeNIe is written for the Windows operating systems. Installation of QGeNIe under Windows operating systems may require administrator privileges. While we cannot guarantee 100% compatibility, we are verifying with each build that it runs on macOS (formerly OS X) and Linux under Wine. Please see QGeNIe on a Mac section for more information on running QGeNIe on a macOS. Getting QGeNIe to run under Linux is virtually identical.

QGeNIe version

To determine the version of QGeNIe that you have installed, select About QGeNIe from the Help Menu. The version number is listed in the small frame of the following window:

Example Networks

QGeNIe installation creates a directory named Qualitative Models, containing the following models (all of these models are available for download from BayesFusion's interactive model repository through File menu):

Engine.xdsl

The Engine models several causes of a possible failure of starting a car engine and illustrates the interaction of Causes and Barriers in the DeMorgan gate.

Fever.xdsl

The Fever model illustrates the interaction of Causes, Barriers, Requirements and Inhibitors in the DeMorgan gate.

Fire.xdsl

The Fire model has been developed for the purpose of explaining the four types of causal interactions defined in the DeMorgan gate that is at the foundations of QGeNIe models. The model has first appeared in (Druzdzel 2010).

Pregnancy.xdsl

The Pregnancy model illustrates working of a Requirement in the DeMorgan gate.

Product Temporal.xdsl

The Product Temporal model is a qualitative dynamic Bayesian network (DBN), illustrating higher order temporal influences.

Productivity.xdsl

The Productivity model is a simple qualitative network used in the Hello QGeNIe section of this manual and it models various causal factors in productivity.

Project.xdsl

The Project model illustrates a causal graph for group brainstorming about various project obstacles and results from the point of view of an airplane manufacturer.

Stability.xdsl

The Stability model has been developed by Bradd C. Hayes & Jeffrey I. Sands and published in: Bradd C. Hayes & Jeffrey I. Sands, "Doing Windows: Non Traditional Military Responses to Complex Emergencies." DSD Research Report 97-1, Decision Support Department, Center for Naval Warfare Studies, U.S. Naval War College.
