What domain is this anyway?

• Command and Control– Lots of decision makers, looking at tactical data, making command

decisions.– Lots of monitors– Lots of data– Lots of decisions to make

• Types?– Tactical actors (manned/unmanned components)– GUI elements (human interfaces)– Vignettes (tactical tests)

• Example vignette:– A UAV is sent to a location to look for red trucks. After a red truck is spotted,

the UAV reports its location. The C2 staff tell that UAV to “track” the red truck. The UAV then stays as close as it can.

• Example problems:– What kind of UAV is it? What kinematic/dynamic properties does it have?– What connection/network settings do I use? Am I communicating via TCP/IP,

or something more primitive? How do I operate under non-robust network assumptions?

Characteristics of the integrative modeling environment

• Abstractions– Communication by message passing (i.e., interaction models)– Messages are strongly typed (i.e., interaction types)

• Generate Structure for Existing Implementations– Code synthesis of interaction types permits multi-language

implementations• Use MATLAB, Java, c++, Colored Petri-Nets, etc., for implementation

– Underlying discrete-event simulator permits pause/resume– Scenarios are independent of types

• Enable Experimentation– Runtime infrastructure enables various delays– Logging infrastructure for after-experimentation comparisons

UA Work and Contributions: Today’s Agenda

• Scenario realism: a brief demo, and motivation for new technology– Permit pathological behavior by an opponent, to test C2 abilities

• Algorithms for camera-based detection– How to simulate camera-based sensors in a heterogeneous

environment

• Aerial search algorithms to detect ground vehicles– What is the best way to look for a vehicle on the ground?

• Control for search/tracking of aerial vehicles– Necessary components, and realistic values

• Future work enabled– Modeling of Embedded Human Systems
