Simulation for ARPI and the Air Campaign Simulator

We describe a simulation substrate for building real-time simulators in a Common Lisp environmerit, and a simulation of Air Campaign Planning implemented in the substrate. The subtrate is designed for experimental work: Trials are repeatable and randomness is carefully controlled; all aspects of the simulation are instrumented and integrated with the UMus CLIP/CLASP instrumentation and analysis package. The ACS simulator is for testing campaign-level planners and simulators.
