Force Equivalence Indices.
Abstract
This study was motivated by the need to revamp the computation of force ratios in the Force Comparison Model (FORCECOM). FORCECOM applied a series of multipliers to scores based on laboratory performance of the systems involved. The formulas used to derive these multipliers came from the historical analysis of Du Puy. The goal in deriving Force Equivalence indices was to develop an algorithm which meets the following criteria: 1) It produces reasonable results for any killer-victim matrix to which it is applied; 2) Its mathematical formulation is the simplest possible; and 3) The interpretation of the above formulation does not run counter-intuitive to equations used in the physical sciences. Research showed that analysts took two approaches to assigning scores to weapons. The first was to use the eigenvector corresponding to the largest eigenvalue of the adjusted killer-victim matrix. This approach, however, is limited to non-zero matrices and a certain class of non-negative matrices. Other analysts such as Johnsrud developed non-linear methods. The ways in which they attained the desired non-linearity for their equations are not intuitively obvious. Under close examinations, their algorithms violate accepted physical formulas. The Potential-Antipotential Algorithm is based on the 'Job = Rate * Time' format.
