Because the U.S. Air Force does not have an effective way of allocating limited funding for depot-level repair across weapon systems and calculating the readiness implications of such allocations, this report describes a methodology, the Closed-Loop Planning System, that estimates the effect of depot repair funding allocations on aircraft availability.

On October 4, 1992, an El Al freight aircraft crashed into an apartment complex near Amsterdam after taking off from Schiphol airport. This disaster generated sufficient public arousal that the Netherlands government deemed it necessary to make a careful reexamination of the external risks of the airport prior to proceeding with expansion plans. RAND's European American Center was asked to do this study. A six-month survey and analysis of the safety issues performed by RAND using a multidisciplinary team of risk experts, aviation consultants, statisticians, and policy analysts. Both quantitative risk estimates and public opinions of airport risks and benefits played importantly in the analysis. Recommendations included safety management changes, safety incident tracking and better public communication. Two reports, "Airport Growth and Safety: A Study of the External Risks of Schiphol Airport and Possible Safety Enhancement Measures," and "Airport Growth and Safety, Executive Summary of the Schiphol Project," were completed under the project.

Many analysts and decisionmakers argue that an order-of-magnitude leap forward in military modeling for the post-Cold War era--particularly campaign modeling--is essential to improve the quality of analyses, training, acquisition, test and evaluation, and innovative thinking. This research has been a step to ensure that the next-generation campaign models will not be mere rewrites of tools currently in use. The authors investigated alternatives to four aspects of modeling they think are essential to improving theater-level campaign analysis: (1) how to create more flexible structures to simulate the wide range of future scenarios and their associated uncertainties; (2) how to link to more detailed models in an analytically valid way; (3) how to represent ground forces maneuvering at the theater campaign level; and (4) how to represent adaptive behavior and aspects of command and control better in this type of model. This research provides insights into some of the alternatives and suggested some promising directions. The authors built the prototype Theater-Level Campaign (TLC) model and used it as a test bed for the different approaches. In many cases, methods were tried and then, finding they were not promising, that code was removed, and research started over in the true spirit of prototyping. The authors believe this type of prototyping and experimentation is critical to the advancement of the state of the art of campaign modeling and analysis. The various sections of the report describe the results associated with each aspect of the experimentation and conclude with more general observations and recommendations for the future.

The Dyna-METRIC model was developed to study and predict the readiness of groups of aircraft squadrons as determined by a major subset of logistics resources, namely, those associated with component repair and resupply. This report describes the mathematical approaches to modeling the effects of spare parts supply, component repair, and related processes on combat capability. It does not describe the implementation of any specific version of Dyna-METRIC. Section II reviews the time-dependent pipeline equations. Section III describes time-dependent stockage and component-repair measures of performance. Section IV combines these measures to give aircraft capability measures. Section V introduces the pipeline model for indentured components, while Sec. VI describes the pipeline equations for the time-dependent, multiple-echelon model. Section VII describes the optimization techniques for supply requirements, and Sec. VIII describes the approach for limited service facilities.

Efficient movement of freight within the United States and across its borders is a critical enabler of future U.S. economic growth. The authors provide an overview of the freight-transportation system and the problems it faces, concluding with a discussion of key system-modernization issues, including increasing capacity, making the system less vulnerable to disruption, addressing environmental concerns, and building support for funding.

To ease the burden of deploying large amounts of aircraft, personnel, and equipment to theatres of operation in times of crisis, the Air Force has reorganized into an Expeditionary Aerospace Force. This work covers a way for defining the structure to speed deployment to forward operating locations.
