Analysis of sequential exchanges between vulnerable forces

Description: A multi-stage and -step analysis of sequences of crises or exchanges shows that aggressiveness on one side can induce rapid counter-value strikes by the other as well and knowledge that opponents will later become less aggressive does not mitigate the tendency to strike early in crises.

Economic impacts study

Description: This is a progress report on the first phase of a project to measure the economic impacts of a rapidly changing U.S. target base. The purpose of the first phase is to designate and test the macroeconomic impact analysis model. Criteria were established for a decision-support model. Additional criteria were defined for an interactive macroeconomic impact analysis model. After a review of several models, the Economic Impact Forecast System model of the U.S. Army Construction Research Laboratory was selected as the appropriate input-output tool that can address local and regional economic analysis. The model was applied to five test cases to demonstrate its utility and define possible revisions to meet project criteria. A plan for EIFS access was defined at three levels. Objectives and tasks for scenario refinement are proposed.

Freedom to mix vulnerable offensive and defensive forces

Description: The freedom to mix offense and defense to expand without diminishing either side`s second strike capability is shown to be counterproductive at large numbers of missiles; effective at intermediate numbers; and progressively less effective at modest numbers. Solutions are less stable for large second strikes.

The incorporation of high resolution climatological data into environmental tactical decision aids.

Description: The environment can significantly impact the performance of weapons systems and how they are used in a theater of operations. A tool has been developed by the US Army Research Laboratory (ARL) to enable operators to assess the impact of environmental factors on the performance of military systems, subsystems, and components. The ARL system, the Integrated Weather Effects Decision Aid (IWEDA) takes weather and environmental data and compares them to a set of rules that relate environmental parameters to weapons system performance. The results from the IWEDA system can enable operators to identify regions and time periods when weapons system performance may be marginal or unfavorable. The Department of Defense (DOD) Air and Space Natural Environment (ASNE) Executive Agents have developed a program, the Advanced Climate Modeling and Environmental Simulations (ACMES), to produce high resolution gridded data for use in generating high resolution climate statistics from simulated weather observations at any desired location around the world. It is intended that data from the ACMES effort could be used by commanders to assess the environmental effects on operations. This paper describes an effort to use data generated from ACMES to drive the IWEDA rules on system performance. The results from this effort are high resolution, gridded values of weapons performance statistics that can be used to support the mission planning cycle.

Military airborne and maritime application for cooperative behaviors.

Description: As part of DARPA's Software for Distributed Robotics Program within the Information Processing Technologies Office (IPTO), Sandia National Laboratories was tasked with identifying military airborne and maritime missions that require cooperative behaviors as well as identifying generic collective behaviors and performance metrics for these missions. This report documents this study. A prioritized list of general military missions applicable to land, air, and sea has been identified. From the top eight missions, nine generic reusable cooperative behaviors have been defined. A common mathematical framework for cooperative controls has been developed and applied to several of the behaviors. The framework is based on optimization principles and has provably convergent properties. A three-step optimization process is used to develop the decentralized control law that minimizes the behavior's performance index. A connective stability analysis is then performed to determine constraints on the communication sample period and the local control gains. Finally, the communication sample period for four different network protocols is evaluated based on the network graph, which changes throughout the task. Using this mathematical framework, two metrics for evaluating these behaviors are defined. The first metric is the residual error in the global performance index that is used to create the behavior. The second metric is communication sample period between robots, which affects the overall time required for the behavior to reach its goal state.

Stability versus first strike costs during deep reductions

Description: Reducing missile forces ultimately increases stability. However, for vulnerable forces, that increase is accompanied by an increase in first strike costs, which would disincentivize force reductions. For survivable forces there is a useful region in which weapon reductions could increase stability while reducing first strike costs.
