Quantitative analysis, specifically in this thesis which studies the Quantified Judgment Model (QJM), has been used consistently as a method of analyzing ground combat. If the QJM model is to be used as a basis for making' important ground combat decisions, then its internal mathematical consistency and military soundness must be fIrmly established. A universal requirement is that any model be both reasonable and valid, in which case the model itself must be able to withstand careful scrutiny. In the case of the QJM, a dimensional analysis to ensure ,.' mathematical consistency of the variables and submodels is one test of the reasonableness of the model. Dimensional analysis tests are applied in this thesis to examine the validity of the QJM. We also perfonn some analyses to determine how sensitive the outcomes predicted by the mooel are to the values of several of the coefficients appearing in its submodels. The fInal chapter presents our conclusions and recommendations for further investigation of the QJM.
