Naval operations involve a complex, interconnected set of effects that are produced by the combined effects of all combat systems on platforms in the operating area. Operational effects include intelligence, surveillance and reconnaissance capabilities such as those provided by ship radar and sonar systems defensive capabilities, such as those provided by anti-missile and anti-torpedo systems and strike and communications systems. The combat systems that provide these effects are dependent upon electrical and fluid resources from ship auxiliary systems such as the ships electrical distribution and potable water supply systems. Because of these dependencies, ship auxiliary system failures can cause combat load failure, which in turn, can cause mission failure. To effectively manage a fleet of ships, commanders must understand the current and projected operating capabilities of the ships. Specifically they must understand the current and future status of the combat loads. Understanding the status of the combat loads requires that commanders understand auxiliary system status and associated impacts on combat load availability. Viewed in their entirety, the auxiliary systems of a set of ships maneuvering in a common operating area represent a massively complex, time-critical, non-linear system. The complexity of ship systems makes it impossible for human commanders to personally manage the intimate details of each auxiliary system and assess the impact individual components within the auxiliary systems have on the ship combat loads and mission success. Commanders require tools to identify mission and combat load impacts from current and predicted changes within ship auxiliary systems. For several decades now the Navy has been researching automates tools and techniques for assisting the commanders and sailors in understanding and controlling the ship auxiliary systems.
