10IPT: DSS Types (2)

posted May 1, 2012, 2:57 PM by Eddie Woo
We're continuing on from Monday's lesson, looking at the different kinds of decision support system. We'll finish off our thoughts on expert systems, and then dig into the most complex and trickiest DSS of them all...
  1. Expert Systems
    Outline the disadvantages of an expert system when compared to an expert.

  2. Artificial Neural Networks
    (a) Identify the basic concept that neural networks are based upon. Propose arguments for and against the use of this particular concept as the model of a computer-based information system.
    (b) Neural networks and expert systems are both designed by human software engineers. Contrast the relationships between these two decision support systems and their designers.
    (c) A neural network's designer is often incapable of providing an explanation for the decisions made by the network as a whole. Explain how this can be the case.
    (d) Compare the characteristics of parallel processing systems and neural networks.
