RAND was asked to design and select a sample of Air Force personnel who would be asked to participate in an online survey of cultural attitudes. The design needed to minimize the number of people asked to participate so as to reduce the survey burden on a population already frequently invited to take surveys; reflect the response rates anticipated from previous surveys of the population; ensure adequate representation of a number of minorities of interest (rank, job type, race and ethnicity, gender, religion, and component); sample enough people in each of the overlapping subset categories of interest (e.g., black female NCOs) to allow for statistically meaningful comparisons; and minimize the number of service members invited to take both this survey and a health survey on an overlapping set of topics scheduled for the same time period. This report describes the method developed for designing joint samples for both surveys.

This report is a user's manual for the Logistics Decision Model (LDM), which was developed by the Performance-Oriented Logistics Assessment (POLA) project to help build the logistics portion of the Army five-year program. POLA estimates the effects on combat performance of alternative investments in logistics resources. LDM simulates the ways that Red and Blue combat forces are influenced by combat service support capacities (e.g., transportation, ammunition handling, maintenance) and logistics resources (e.g., stocks of ammunition, war reserve equipment, replacement personnel). By itself, LDM cannot do all that is required of the POLA methodology. It can estimate the effect on combat performance of varying the capacities to perform certain logistics functions, such as ammunition handling, but those capacities must be estimated from physical resources. LDM reads data from four different types of input files: the ATTRITION file contains data that relate the outcomes of combat to the numbers and kinds of weapons engaged; the SUPPORT files describe the structure and activities that support the combat forces; the TIME PHASE file specifies the amount of each resource that enters the simulation; and the OUT SPEC files specify what variables appear in the output files. LDM contains two modules that perform computations: the support module computes the rates of all activities performed by the theater support structure to make weapons available for combat, and the combat module computes the outcomes of combat between the available Blue and Red weapons. Activities (and many combat outcomes) are defined by their effects on resources, such as consumption, production, or transport.

Performance-Oriented Logistics Assessment (POLA) has developed a prototype methodology to help build the logistics portion of the Army five-year program. The POLA methodology estimates both the costs and the effects on combat performance of alternative logistics improvements. By comparing their costs and effects on combat performance, one can arrive at a balanced program that provides greater combat effectiveness for each logistics dollar spent. This report briefly reviews the POLA methodology and its uses.

The number of fighter aircraft in the Air Force inventory is decreasing, but the demand for experienced fighter pilots is increasing. The authors use a dynamic mathematical model to show that, to keep from damaging fighter unit readiness, fighter pilot production in the active Air Force must be reduced and new approaches to developing and managing personnel with fighter pilot-like skills must be adopted.

Situational and tactical factors, which are usually treated only in complex models, strongly influence the effectiveness of long-range precision weapons in interdicting a moving armored column. This study develops a physics-based personal-computer model describing such influences. It draws on high-resolution simulation experiments for both insights and "data" useful in calibrating the simpler model. That model (PEM) explains results of the high-resolution simulation that had previously not been understood and makes it possible to estimate effectiveness over a wide range of circumstances. Results vary by about two orders of magnitude. The study can be seen as a prototype demonstration of the value of working the gamut from high-resolution, entity-level, man-in-the-loop simulation to exploratory analysis with fast-running multiresolution desktop models. The result is a very useful, and partially integrated, family of models.
