| When asking a customer when they need something done you've most likely heard the reply, Yesterday! Why is this answer so common? Possibly it's because customers typically do not request products until they are needed. I liken this phenomenon to my lunchtime habits. I don't go looking for food until I'm saying out loud, I'm starving! Both are an exaggeration, but both cause the consumer to seek out those who ... |

Transparent assets (e.g., road blocks) are those for which we assume positions are known by both attackers and interdictors. Decoys and traps are deceptive assets. Decoys are meant to be perceived as effective interdiction assets by attackers, while traps are not perceived. We use a mathematical optimization model ... |

| The C++ computer language is well suited to model multi-vehicle engagements. Its prowess is exemplified by the conversion of a unmanned aerial vehicle simulation from FORTRAN to C++. The new architecture accommodates besides UAVs and moving targets also targeting satellites. Its class structure is outlined, and the communication bus between the encapsulated vehicle-objects is discussed. A generic UAV model with five degrees-of-freedom fidelity is used to demonstrate the interactive features ... |
