Abstract

Dstl examines battle simulations based on stochastic evolution codes. One such code, known as SIMBAT (SIMple BATtle program) models the evolution of the battle as a sequence of turns in which the two sets of combating units move in a landscape. The units have objectives and act accordingly, they can acquire enemy units if lines-of-sight in the landscape permit this, and they can fire upon and disable enemy units with a certain probability. Based on the setting of a large number of parameters, and also on the outcome of pseudo-random decisions and engagements made in the course of the action, a final outcome of the battle is achieved. Figure 1 shows a SIMBAT screenshot.

The problem posed to the Study Group is the following: Is it possible to analyse and subsequently calculate a battle in terms of smaller subunits which can then be aggregated into the whole in a systematic fashion? This could potentially speed up the processing of a large number of simulations.
