The F-35 Lightning II Joint Program Office has relied upon the Logistics Composite Model Analysis Toolkit (LCOM ATK) to provide support to planned analyses that verify Key Performance Parameter (KPP) requirements as well as conduct ad hoc analyses. As the F-35 has been transitioning into an operational environment, it has become more urgent to have the capability to robustly analyze all variants of the F-35 aircraft with the most current data possible. Incorporating new data into the F-35 LCOM ATK model inputs has become a cumbersome and manually intensive effort. The need to incorporate changing data sources required new technology to develop model inputs for the LCOM ATK models and a flexible and adaptable model building capability to model real world operational conditions and constraints. In this effort, FTI significantly enhanced LCOM ATK front- end capabilities in data preparation by developing the Logistics Data Processing Suite (LDPS) and Model Builder (MB). FTI showed how data from diverse data sources such as LM Aero’s ATLAS database as well as Failure Reporting and Corrective Action System (FRACAS) could be used to produce updated F-35 LCOM ATK model input files in a fraction of the time it would have taken otherwise. Additionally, FTI was able to produce audit forms through automation that resulted in savings of hundreds of analyst hours. By reducing the time and effort to support analyses with modeling, these capabilities will help the F-35 JPO to make better decisions more quickly.
