10IPT: Expert System Structure

posted May 7, 2012, 2:27 PM by Eddie Woo
Last week, we looked at the four major categories of DSS. Today, we're going to revisit one of them - expert systems - and take them apart to see how exactly they do the job of mimicking a human expert (no small feat!). 
  1. Describe and analyse the four main components of an expert system. 
  2. Distinguish between the two kinds of inference engine, and provide examples of where each one is useful. 
  3. Define the term 'fuzzy logic', and explain why it is useful in decision support systems.
  4. Consider the list of potential HSC subjects below. Write up two detailed sets of instructions to guide an expert system, one with forward and the other with backward chaining, to help people decide what subjects they should select for the HSC.
