Preface
As part of a body of research defining and evaluating the concept of
Lean Logistics for the U.S. Air Force, this report considers the effects
on operation of the C-5 Galaxy of radically reducing the time required
to move and repair components of that airlift aircraft. The analysis
uses Air Force data to drive simulations of C-5 logistics operations
and considers peacetime flying programs.
This research was conducted in the Resource Management and
System Acquisition program of Project AIR FORCE. It is one element
of the Logistics Project, sponsored by Headquarters, United States Air
Force (AF/LG). Headquarters, Air Mobility Command (AMC/LG),
and Air Force Materiel Command (AFMC/XP) provided important
assistance in ensuring the successful design and execution of this
project. This report should be of interest to persons concerned with the
logistics support of airlift aircraft and, particularly, to logisticians
involved in the management of aircraft recoverable spare parts.
Project Air Force
Project AIR FORCE, a division of RAND, is the Air Force federally
funded research and development center for studies and analyses. It
provides the Air Force with independent analyses of policy
alternatives affecting the development, employment, combat
readiness, and support of current and future aerospace forces.
Research is performed in three programs: Strategy and Doctrine,
Force Modernization and Employment, and Resource Management
and System Acquisition.
