The overall objective for this SBIR is to develop, or augment existing, Modeling, Simulation and Analysis (MS&A) techniques that will provide insights into opportunities to significantly reduce system support costs for the US Air Force. However, our highest priority and initial focus must be on the identification, design and development of an integrated data architecture spanning the maintenance and supply domains within logistics. A fundamental contribution of this project is to define the integration path(s) between items (NIINs) within the supply domain and their corresponding work unit codes (WUCs) within the maintenance domain.
