Perhaps the largest project has been the STEAMER project which incorporates layers of object abstractions for a steam plant. At Penn, we have a multi-level simulation system (HIRES) that permits the construction and interactive control of process abstraction layers. We also have a facial animation system (OASIS) that incorporates local area expression simulations. Both HIRES and OASIS utilize the Iris Workstation 2400 (Silicon Graphics, Inc.) for real-time animation. Rand Corporation (Santa Monica, CA) has been involved with object oriented simulation for quite some time (I think they have an example graphical simulation of a battle scenario). You should also check out the commercial enterprise, Pritsker Associates, who sell a graphical simulation package. Some references are given: 1. Hollan James, Hutchins Edwin, Weitzman Louis - "STEAMER: An Interactive Inspectable Simulation-Based Training System", AI Magazine (Summer 1984). 2. Fishwick, Paul - "Hierarchical Reasoning: Simulating Complex Processes over Multiple Levels of Abstraction", Ph.D Thesis, Univ. of Pennsylvania, 1986 (MIS-CS-85-21). 3.

McArthur, David and Sowizral, Henry - "An Object-Oriented Language for Constructing Simulations", IJCAI 1981. An important issue with "AI and Simulation" is determining where the "ai" is in simulation. The answer to that may best be found in the special workshop in AI and Simulation to be held at AAAI-86. Even though graphics is not explicitly mentioned, you should also check out the qualitative reasoning/simulation literature (de Kleer, Forbus, Kuipers, and others) in past IJCAI/AAAI's. Also "aggregation" is receiving wider attention these days: look at Goldin & Klahr (IJCAI '81) and Weld (IJCAI '85). -paul CSNET: fishwick@upenn
