Detroit, MI, USA          Sponsored by AAAI          Sunday, August 20, 1989  


Systematically representing and reasoning about the structure and function of
a system offers significant advantage in design, analysis, monitoring,
diagnosis, and control.

This workshop will provide a forum for defining and discussing issues that
arise from or underly the use of Model-Based Reasoning (MBR).  This includes
familiar applications in monitoring and diagnosis, and other areas of strong
interest such as system control, planning, analysis, theory construction,
tutoring, or design/redesign.

The workshop seeks papers that offer new approaches and insights to
fundamental problems associated with MBR, some of which are listed below.
This is not a forum for descriptions of system implementations or
applications, although analyses of experiences with MBR may be of interest.


We encourage papers which address questions such as the following:

* What inference mechanisms take best advantage of explicit structural and
  behavioral representations? What are their power and limitations?
* Conversely, what do these inference mechanisms require of a structural
  representation or a behavioral simulation?  To what class of systems is MBR
  now applicable in a straightforward and useful way?  
* What factors may have led to failure in the use of MBR, or to its
  abandonment?
* Is there a complexity barrier beyond which systems cannot be effectively
  modeled?  Are there types of complexity that affect MBR differently?
* How does MBR apply to qualitative, quantitative, or mixed domain
  descriptions?  Do MBR's methods apply uniformly to analog and discrete
  objects?
* Is there a taxonomy of uncertainty or incompleteness in models?  Do any of
  these contraindicate the use of MBR?
* Can MBR use arbitrary sources of heuristic knowledge without compromising
  its power?
* How can models cope when the domain's behavior exhausts computational
  resources?  Can models use speed/accuracy tradeoffs?
* Can one infer changed or unknown structure from observed or desired
  behavior?
* Are there systematic approaches to the "model construction bottleneck?"


A number of problems of domain representation still challenge the generality
of MBR.  For example, how shall our models handle:

   ~ embedded software;
   ~ feedback, state-dependency, or other forms of time-dependency;
   ~ open systems, including sensing of external environments and initial
     ignorance of structure;
   ~ systems with virtually no physical structure (e.g., chemical process
     control);
   ~ globally complex systems, rich in interaction paths between relatively
     simple components;
   ~ systems with complex geometric relationships; or
   ~ translation between physical and computational models (e.g., pipes and
     valves to pressures and flows), including derivation of global
     parameters from aggregated models?



To facilitate discussion, acceptance will be limited to 35 papers and 10-12
presentations.  There will be an informal proceedings of all accepted
submissions.  More formal publication will be pursued if there is sufficient
interest.  All attendees will be invited to prepare single page descriptions
of their work for distribution prior to the workshop.  Each presented paper
will have a commentator.

The workshop's organizing committee consists of: Randy Davis, MIT; Johan de
Kleer, Xerox PARC; Richard Doyle, JPL; Dan Dvorak, UTexas; Mike Fehling,
Rockwell, Mike Genesereth, Stanford; Walter Hamscher, Price-Waterhouse; Ethan
Scarl (chair), Boeing Computer Services; Narinder Singh, Stanford; and Brian
Williams, Xerox PARC.

The submission format will be short, self-contained papers of no more than
2000 words.  Recent extensions and condensations of work already submitted to
IJCAI or elsewhere is permissible, so long as any duplication is explicitly
noted.  The preferred medium for submission is electronic mail of plain ASCII
files without formatting commands or control characters, and sent to:

ethan@atc.boeing.com

Figures may be faxed to (206) 865-2946, unless their quality or quantity is
prohibitive.  Alternatively, three hardcopies may be sent to:

Ethan Scarl Boeing Computer Services, P.O. Box 24346, M/S 7L-64 Seattle,
Washington, 98124-0346
(206) 865-3255 [office]
