Over the past decade, Draper’s traditionalexpertise in extremely reliable guidance,navigation, and control systems hasevolved into expertise in the collection,transmission, management, and application of informationfor closed-loop improvement of complex, real-time systems.Draper’s Information Technology Engineering Directoratedevelops both information dissemination management andinformation application technologies for this class ofsystems, including military command and control systemsand large-scale transportation and logistics systems.Information management capabilities address the hardwareand software components of systems for archiving,cataloging, and disseminating information products tousers in a dynamic, bandwidth-limited environment wherethe information sources may also be distributed.Multilevel security to support information dissemination ina coalition environment has also been developed anddeployed. In addition to storage and retrieval, otherfunctions that comprise information management servicesinclude assured delivery, authentication, and changedetection.information for problems in military command and controlas well as transportation and logistics. Modeling andanalysis tools are being developed to provide planning anddecision support for the Integrated Munitions ManagementProject (IMMP) being sponsored by the Army’s MilitaryTraffic Management Command (MTMC).The following paper, “Evolutionary Concepts forDecentralized Air Traffic Flow Management,” by M. Adams(Draper), S. Kolitz (Draper), J. Milner (WashingtonUniversity), and A. Odoni (MIT) reports on jointDraper/MIT efforts in modeling, simulation, andoptimization funded by NASA’s Advanced Air TransportationTechnologies (AATT) program for the development oftechnology in support of the evolution of the U.S. airtransportation system’s evolution toward “free flight.”The utility of real-time tactical information provided byinformation management services can be significantlyenhanced by visualization and decision support tools thataid the warfighter in achieving situational awareness anddeveloping and executing courses of action. Thus, anothercomponent of Draper’s Information Technology activities isthe development of Command, Control, Communications,and Intelligence (C 3 I) applications. Extending workstarted in the 1980s in real-time mission planning systemsfor autonomous vehicles, Draper has developed a variety ofsystems to aid the warfighter in real-time planning. Theseinclude geospatial and temporal course of actiondevelopment and analysis tools for both small unitoperations for Special Operations Forces and maneuverplans for activities at Corps and Division levels.Other information applications efforts have been focusedon the development of applications for the use ofIntroduction
