A Dynamic Model of the Initial Spares Support List Development Process
Abstract
The Initial Spares Support List (ISSL) is an integral part of the Air Force initial provisioning process. Its purpose is to provide an adequate range and depth of spare/replacement parts to keep a newly activated end item in operation until normal supply channels are developed. Historically, the ISSL has provided either too few or too many parts. These inaccuracies have resulted in either excessive system down time or an excessive amount of money spent on spare/replacement parts. As a result of these problems, Air Force Logistics Command requested that a dynamic model of the ISSL development process be developed. The authors used the system dynamics approach to analyze the decision and policy making structure of the process. They constructed a dynamic model of the system and implemented the model on the computer with the DYNAMO simulation language. The model has been internally validated but needs to be verified with real world data. Once this has been accomplished, the model could be used as a tool to analyze the present ISSL policies and to experiment with revised policies in an attempt to provide more efficient support to Air Force end items.
