VisiRule Expert System Demos
Legal Problem Solving, Financial Problem Solving and Machine Diagnostics. As the VisiRule software has its roots in, and access to, Prolog - the world's foremost logic programming language, there is really no limit as to what can be implemented. In addition, there is support for Business Rules via the English-like expert systems language, Flex and Prolog. This page features various VisiRule expert system demos which show some of the more advanced and versatile aspects of VisiRule such as database access, date capture and manipulation, and HTML integration. There are other demos available which deal with industry specific challenges such as

Nepa Forest Restoration Assessment
The National Environmental Policy Act (NEPA) is a US federal law that requires land management agencies like the US Forest Service to conduct an environmental analyses of the potential impacts of proposed land management activities. Land management proposals go through a public review and comment period, and public comments are considered and addressed before a final decision is made. The standard NEPA process typically requires a lot of time and effort, often running to many months to years (for large projects), before a project is approved.
Policy Risk Assessment
Checks to see if you have certain documented policies in place - generates custom advice and produces a calculated risk score using scoring weights.
Also captures additional User Text Input.
These can be adjusted to illustrate dynamic scoring.
Creates a timetable for teachers who can only teach according to certain restrictions such as freetime, and subject competence. Demonstrates how to combine VisiRule Q&A with Flex forward-chaining rules for planning and scheduling. Allows for the creation of new teachers to help fill the timetable.
Fuzzy Logic Demo
A simple fuzzy logic demo showing how much tip to leave in a restaurant.

Vroom Yetton Model
The Vroom-Yetton model is designed to help identify the best decision-making approach and leadership style to take, based on the current situation. It was originally developed by Victor Vroom and Philip Yetton in their 1973 book, "Leadership and Decision Making."
Medical stereotypes are a well known, ranging from the hippy-esque GP, to the man-mountain of an orthopaedic surgeon, via the suave and sophisticated plastic surgeon.
Toby Hillman's explores this with his light-hearted flowchart "Did you choose them, or did they choose you?"
