Not only has it been done, but it is called a "blackboard architecture". There are at least two books which are collections of papers on this subject. There have also been workshops associated with the AAAI conference. I think there have been 5 or 6 of these, which have proceedings you might be able to get. I think there has been one IEEE Expert magazine issue devoted entirely to this idea. The basic trick is to get an good data base system and interface it to a rule based expert system. The data base is usually object oriented, but doesn't need to be. The one feature it must have is triggers, so that the expert system rules can be triggered when needed. The expert system rules add a fact to the blackboard by adding it to the database, where the other exter systems can see it. All of my references are several years out of date, but I can send them to you on request. You might also look at creating your own blackboard shell, perhaps out of POSTGRES (Berekely's extendable hybrid database) and CLIPS (NASA's embedable rule based expert system shell.)

Nance - SRC <srcnance@popeye.cs.vt.edu> To: simulation@bikini.cis.ufl.edu Subject: Abbott's Inquiry on the Existence of a Shell Cc: fishwick@bikini.cis.ufl.edu, srcnance@popeye.cs.vt.edu Model development environments have the objectives, at least in part, that you seek. The Condition Specification (see C.ACM, Feb. 1985, pp.190-201) is a rule-based model specification tool. Numerous other environments, some sold as commercial products, exist. Rozenblit and Zeigler at U. Arizona, Balmer and Paul at LSEPS, Narain and Rothenberg at Rand are examples from the research domain. Check the session at WSC'90 on "A Dynamic View of Simulation Support Environments." You might also check the special issue of the Journal of the Operational Research Society, August 1987.

What I am trying to create is a simulation of the minor league system in Major League Baseball. That is, simulate bringing a player up through his development. To do this, I need to simulate multiple games based on a variety of probabilities ... some not definite (ie power, speed). On this list, everyone has been discussing that information is available on baseball simulations. IF ANYONE HAS SOME INFORMATION THAT IS WORTHWHILE, or for that matter any baseball simulation information, I WOULD GREATLY APPRECIATE IT AND PROBABLY REWARD YOU FOR HELPING ME GET MY HANDS ON IT. If anyone is interested, I could post some mail on how I have developed V07.00 of my current baseball simulation. Not being a schooled statistician or simulations programmer, it may look like a hack job. What it is is a fairly accurate simulation. Thanks! ------------------------------ Date: Tue, 18 Sep 90 09:06:36 EDT From: fujimoto@cc.gatech.edu (Richard Fujimoto) To: haney@cs.uiuc.edu Subject: shark's world simulation Cc: simulation@bikini.cis.ufl.edu This is in response to your querry in the simulation newsgroup regarding the sharks world problem: Sharks world is a problem proposed by some folks with Jade simulation (Brian Unger, John Cleary, others) as a benchmark for evaluating the effectiveness of parallel discrete event simulation algorithms. Its intent is to try to capture the essence of problems that arise in practice where several simulation entities move over a physical terrain and occaisionally interact (e.g., combat simulations). A goal in devising the benchmark is that the problem be easy to understand so that the programmer need not be an expert in a specific problem domain. Sharks is not unlike the "colliding pool balls" benchmark used at JPL, but is easier to program because working out the physics in pool balls is time consuming. There was a short paper describing the problem in the 1990 Distributed Simulation Conference last January. I organized the focus session at WSC '90; Dick Nance came up with the initial idea for the focus session (though using sharks was my idea). Three groups have each implemented Sharks, each using a different parallel simulation mechanism: JPL implemented it using Time Warp, David Nicol and his student (William & Mary) used a conservative algorithm, and Rajive Bagrodia and his student (UCLA) use something called space-time simulation, originally developed by Chandy and Sherman, and based on Unity. The idea of the session is to compare their experiences. Hope to see you there!

I am interested in exaqmining the source code, with the end result probably being a port to HP-UX workstations, or a simple graphics based flight simulator. I am aware of the SUN SPARKstation flight simulator, but obviously I cannot ask SUN for the source code, so I am making a request to the general net population. If you have some source, should be in public domain, I would appreciate an email message from you describing the source, and features. C is the preferred language, but anything will be happily accepted. Please note that this project is to be done on personal time, and is in no way to be construed as being either sanctioned or approved by HP in general.
