Maybe some AI guru out there can help with the following questions:

1. Production systems are the implementation of many expert systems.
In what other forms are "expert systems" implemented?

[I use the term "expert system" to describe the codification of any
process that people use to reason, plan, or make decisions as a set of
computer rules, involving a detailed description of the precise
thought processes used.  If you have a better description, please
share it.]

2. A production system is in essence a set of rules that state that
"IF X occurs, THEN take action Y."  System designers must anticipate
the set of "X" that can occur.  What if something happens that is not
anticipated in the specified set of "X"?  I assert that the most
common result in such cases is that nothing happens.  Am I right,
wrong, or off the map?

Thanks.
