One of the benefits of the analytical tools such as SIBAC is the ability to predict and simulate the scenarios of a system’s performance under various conditions. This ability comes in handy for investigating failures. In failure investigations, one must work with the end result of a device’s or a system’s failure and reach a conclusion as to what caused the device or the system to produce the anomalous end result. SIBAC can facilitate the investigation by running various scenarios until the most probable scenario is found that matches the end result. For example, SIBAC was used along with the available test data to investigate the structural failures observed in the brackets of the 28-Carry Conventional Bomb Module (CBM) for B1-B airplane. Initially the bracket failures were thought to be caused by errors in the loading procedure. However, after the investigation that included careful instrumentation of the CBM and modeling of CBM’s performance via SIBAC, it was found that the contribution from any loading procedure error is an order of magnitude smaller than the contribution from the pyrotechnic actuation of the swing arms in CBM.
