Expert System

Concept type

In GreenDesk, the term Expert System is used in the traditional sense of a system that applies complex rules, conditions, and constraints to model data - and answers to questions - to guide users through completion of worksheets and forms and to alert users to issues - and especially to design choices - that may impact on your green scheme certification score or your application for certification for an industry standard.

Please note: The term 'Expert System' is not used here in the more recent sense of an Artificial Intelligence (AI) "self-learning" system.

All data that is entered into the Project Model Database is monitored by the Expert System, and throughout GreenDesk the system - indicates using special warning icons and diagnostic messages - exactly where any problems or "bad apples" may exist in the model and design.

The Expert System also indicates exactly when any model data values or answers to questions are required for it to perform its calculations, often using these symbols: UNDEF (visit also this tutorial) or UNDEF.

This mini-tutorial is essential reading for all new GreenDesk users: The UNDEF symbol: "Please feed me, I'm undefined (null)"
