Defense planning faces significant uncertainties. This report applies robust decision making (RDM) to the air-delivered munitions mix challenge. RDM is quantitative, decision support methodology designed to inform decisions under conditions of deep uncertainty and complexity. This proof-of-concept demonstration suggests that RDM could help defense planners make plans more robust to a wide range of hard-to-predict futures.

"A first step in dealing with uncertainty is confronting its existence, ubiquity, and magnitude. A second step is dealing with it when informing assessments and decisions. As the Cold War waned, RAND developed new methods that urged sketching the no-surprises future, listing known branch-style uncertainties, and stretching the imagination to envision potential shocks, good or bad (e.g., Soviet Union disintegration or Saddam Hussein's invasion of Kuwait). Major surprises will nonetheless occur, and some of RAND's most important work on uncertainty has to do with coping with surprise developments. RAND's progress in national security uncertainty analysis benefited from a confluence of developments in computer and software technology, theory and practice in strategic planning and decisionmaking, analytic theory and methods, and theory of complex adaptive systems. Work has emphasized facing up to deep uncertainty in many dimensions, performing exploratory analysis of "the possibility space," identifying regions of that space that pose special risks or opportunities, finding options to improve capabilities, and using portfolio analysis to conceive and compare strategic options for economically dealing with the diversity of challenges. A cross-cutting RAND theme is finding flexible, adaptive, and robust (FAR) strategies. Ultimately, different problems call for different approaches to uncertainty. If the theory of planning under uncertainty and preparing to cope with surprise effectively is difficult and complex, this report makes clear that implementing and maintaining corresponding changes is even more difficult and suggests that policymakers to be constantly vigilant in ensuring that related initiatives are not undercut or allowed to wither."--Provided by publisher.

Originally published in 1971, and now published with a new foreword, this is a book of enduring value and lasting relevance. The authors detail the application, history, and controversies surrounding the Planning, Programming, and Budgeting System (PPBS), used to evaluate military needs and to choose among alternatives for meeting those needs.

How do we plan under conditions of uncertainty? The perspective of military planners is a key organizing framework: do they see themselves as preparing to administer a peace, or preparing to fight a future war? Most interwar volumes examine only the 1920s and the 1930s. This new volume goes back, and forward in time, to draw on a greater expanse of history in order to tease out lessons for contemporary planners. These chapters are grouped into four periods: 1815-1856, 1871-1914, 1918-1938, and post-Second World War. They progress from low-tech to high-tech concerns, for example, the first period examines armies, while the second period examines navies, the third asseses navies combined with air forces, and finally for the Kaiser chapter explores nuclear issues and decision-making.

This report is the last of a series in which RAND explores the elements of a national strategy for the conduct of U.S. foreign policy, in this new era of turbulence and uncertainty. Three alternative strategic concepts are presented.
