The Airlift Capabilities Estimation Prototype: A Case Study in Model Validation
Abstract
This study investigates the application of a life cycle approach to the validation of operational models. The classic waterfall life cycle from software engineering is adapted for use on mathematical models by defining four stages of model development. Each stage is discussed in detail and examples of the output from each stage are presented. In addition, techniques are investigated for applying the proposed life cycle to existing models through the recovery of life cycle stages. The methodology is applied to a linear programming model developed for planning airlift operations to demonstrate the power of the life cycle approach to validation. The results of applying each stage of the life cycle to the model are presented. As a final test, the model is used to predict the airlift capability and resource requirements for the Operation Desert Shield airlift. A comparison is made between the predictions of the model and data from the actual operation. The validated model is shown to be a better representation of the airlift planning problem. Finally, specific recommendations are made for operational use of the airlift planning model and on areas where further research is needed on both the model and the life cycle validation approach....
