I'm currently engaged in a small research  project looking  at the problems
of updating AI databases in real time. [By database, I mean that collection
of information  that  I  am  currently  reasoning  against -  not the large
commercial variety.] 

A typical problem in the domain is that you have N (where large(N)) sensors
attached to a process plant all throwing lots of data  with low information
content at an intelligent fault  diagnosis system.  The system  has to cope
with contradictory data, have  good coverage  of the  incoming signals, but
still be able to respond quickly to high-priority situations. 

The particular issues that I am concerned with are:
     (1) what are the representational inadequacies of current AI notations
     that are suited to doing real time problems and/or  handling noisy and
     contradictory data?  

     (2) what are the computational costs of using such notations?

Primary choices  for  handling  mucky,  changing  data  are  the RMS family
(Doyle, de Kleer etc) and other non-monotonic logics, so  these are typical
of the notations that I am referring to. So  the issues  become: what can't
you do with them, and what would it cost anyway?  


The questions I would like to submit to net.land are:
    o anybody doing any work on extending non-monotonic notations in wierd
      directions (eg integrating them with uncertain inference techniques)?
    o anybody got any pet real-time AI problems?
    o anyone else working in the real-time field?

Please mail  responses  directly  to  me,  and  I  will post  a summary for
discussion later. 

Thanks in advance,
Ian.
