Missile Defense Agency Support

OASiS Support To The Missile Defense Integration & Operations Center (MDIOC)

SPEEDES is supported for several significant projects within the Missile Defense Agency (MDA) through Metron’s work at the Missile Defense Integration & Operations Center (MDIOC). The most significant project supported is the Discrete Event Sim, a system level simulation of the entire ballistic missile defense system. Discrete Event Sim contains models of many aspects of the system from threats and interceptors to sensors, battle management systems and tactical communications system.

Discrete Event Sim is used for many different purposes. Its initial purpose was as a wargaming system to support both current events as well as futuristic wargames with proposed or upgraded versions of defense systems. These wargames and exercises run on any of Intel Xeon, Intel Itanium, or SGI MIPS based computers with anywhere from one through over 40 processors. The ability to run on a wide variety of processors allows Discrete Event Sim to model a wide array of small to large scenarios in a soft real time fashion.

Discrete Event Sim is also used for many other purposes such as a replacement for hardware in the loop systems, a model driver for C2BMC development, training, and for performance testing of the deployed BMD system. The flexibility achieved in the system was one of the original design goals that lead to the selection of SPEEDES as the core framework for the model development. Parallel optimistic discrete event models give both the power and the capability to support this wide variety of situations.

The second major project supported is ISIM, the international simulation that is used for both unclassified events and for events not requiring the high fidelity models of Discrete Event Sim. ISIM uses the same basic SPEEDES software as Discrete Event Sim but uses the conservative time management algorithm. The lower fidelity models of ISIM allow the conservative time management algorithm to get sufficient parallelism while freeing the modelers from the additional effort to handle optimistic programming. ISIM runs on multiprocessor windows based 32-bit Intel processors, attached to .Net applications for graphics displays and database logging.

The final major project is the BCM, developed in the Washington DC area, supported and integrated with the Discrete Event Sim at the (MDIOC). BCM is a simulation of the C2BMC, allowing testing of new proposed features of the C2BMC while avoiding affecting the deployed tactical software. This simulation also operates with the actual tactical message sets of the deployed system and can be run both as fast as possible for analysis or slaved to real-time for wargames, human in the loop tests, or as a hardware in the loop replacement.

Metron provides support for the use of SPEEDES in all these situations. Metron is able to provide support in the proper use of SPEEDES, analysis of the models, and aid in writing models that take advantage of the parallel processing enabled by SPEEDES.
