   IJCAI-93 Workshop on Production Systems and their Innovative Applications

		           August 28, 1993

			   Chambery France

Production systems have successfully made the transition from a trendy research
idea to a routinely used programming paradigm. An important cause of this 
transition has been the several orders of magnitude speedup in program 
execution achieved in the past few years by the combination of better and 
faster match algorithms, efficient compilation techniques and faster hardware 
platforms.

A side-effect of the increasing acceptance of production systems is that 
researchers are investigating their applicability for pattern-directed 
processing in novel and innovative application areas. Examples include 
real-time process control, maintaining integrity in  databases, active 
databases, expert databases, high-level image understanding, simulation and 
analyzing results of large scientific computations. In addition, applications 
in traditional areas like expert systems and modeling human cognition are being
scaled up in terms of the number of productions as well as the amount of data 
to be processed. These applications bring new constraints and requirements for 
production systems. Some of these requirements necessitate rethinking of the 
tradeoffs that have been previously made; others indicate that fundamental 
changes may be required.

The goal of this workshop is to develop a coherent view of the requirements of 
contemporary production system application efforts and to use this information
to define the next set of research problems and issues. 

Specifically, the workshop will be an attempt to find answers to questions like
the following:

What is the mix between match and non-match computational requirements in 
     contemporary production system applications and how does it influence 
     implementation decisions?

What are the requirements for using production systems for active/expert 
     databases? What is needed to support maintenance of database integrity?

How does the expected volume of data influence the choice of match algorithm 
     both in main-memory production systems and active databases?

How does the performance of match algorithms vary as problems are scaled up in 
     size?

What is required from production system implementations for supporting 
     real-time process control?

How do response time restrictions influence the choice of match algorithm?

Why implicit parallelism has not yielded usable results for production systems?
     Is explicit parallelism likely to be any better?

Is scaling up of applications likely to increase available and/or achievable 
     parallelism?

What are the limitations of existing production languages? Are new production 
     languages needed? If so, what should they look like?

What are the pros and cons of contemporary production systems vis-a-vis other 
     paradigms for specific applications that require pattern-directed 
     processing? What would be needed to make production systems more suitable 
     for these applications?

What are the promising new application areas?

What are the promising research directions for production systems?


This is not an exhaustive list, rather a sample of the questions the workshop 
is expected to discuss. 

The workshop welcomes both research papers on current work and position papers 
on research directions. The emphasis of the workshop will be on identifying 
potential problems and promising research directions. The papers should be upto
ten pages (10pt) long. Submission of a paper is not a pre-requisite for 
participation in the workshop. Interested researchers are welcome subject to 
space limitations (30-40 attendees). They should send a short description (upto
2 pages) of their relevant research interests. We strongly encourage 
submissions by electronic mail. Latex or postscript submissions are acceptable.
For hardcopy submissions, please send five copies. Submissions should be sent 
to:

The workshop is being organized in conjunction with the International Joint 
Conference on Artificial Intelligence 1993, which will be held in Chambery, 
France, between August 29 and  September 3. Workshop attendees must register 
for IJCAI-93. Registration fee for the workshop is 300FF (about $60).
