STOCEM Investigation of COSAGE Sampling (SICS)
Abstract
The Stochastic Concepts Evaluation Model (STOCEM) is a fully automated simulation of theater combat applied by the US Army Concepts Analysis Agency. The STOCEM was designed as a stochastic version of the deterministic Concepts Evaluation Model 1X (CEM 1X). The STOCEM uses weapons effectiveness data, denoted as combat samples, which are preprocessed by the Combat Sample Generator (COSAGE) simulation. In the SICS analysis, STOCEM case variations are constructed, using a single scenario, with an objective of reducing divergence from deterministic CEM, and of increasing variability of STOCEM results over replications. The STOCEM case variations are constructed by varying the ways that COSAGE combat samples are used in STOCEM, and by varying the types of combat processes represented stochastically in STOCEM. For each case variant, assessment is made of STOCEM divergence from deterministic CEM, and of variability of STOCEM results over replications. Closeness of STOCEM results to historical results is also assessed for selected cases. The principal finding is that the preferred method for applying STOCEM is to deactivate the stochastic FEBA move rate process and to apply a single randomly selected (in each replication) set of COSAGE samples to all simulated battles in a replication.
