Lockheed Martin Aeronautics †F-16 Modular Mission Computer Application Software

About the Comp whatever Although they argon a globular security and information technology company, the majority of Lockheed Martins business comes from U. S Department of Defense and Federal Agencies. In fact, they are the largest fork upr of IT services, systems integration, and cooking to the U. S Government. The remaining portion of Lockheed Martins business is comprised of international governance and some commercial gross revenue of products, services and platforms. Lockheed Martins operating units are organized into broad business areas Aeronautics $11. gazillion in 2008 sales includes tactical breezecraft, airlift, and aeronautical research and information lines of business. Electronic Systems $11. 6 billion in 2008 sales includes missiles and fire control, naval systems, platform integration, simulation and cultivation and energy programs lines of business. Information Systems & Global Services $11. 6 billion in 2008 sales includes C4I (stands for Command, Control, Communications, Computers, and Intelligence), federal services, government and commercial IT solutions.Space Systems $8 billion in 2008 sales includes space launch, commercial satellites, government satellites, and strategical missiles lines of business. Something about the F-16 The Lockheed Martin F-16 Fighting Falcon is a multirole jet fighter aircraft originally demonstrable by General Dynamics for the United States Air Force. approach patterned as a lightweight, day snip fighter, it evolved into a successful multirole aircraft. Over 4400 aircraft lose been built since production was approved in 1976 and it currently serves in the air forces of 25 nations. About the software product systemThe Aeronautics division of LMs, found in Fort Worth, Texas has used the OMGs MDA to develop Application Software for the F-16 Modular heraldic bearing Computer. This software is cross-platform compatible and has highly increased productiveness and quality. Just as the highly demanding environment of avionics software development and the MMC (Modular Mission Computer) itself. What is the MMC? The Modular Mission Computer is a cost-effective MLU (Mid Life Update) for the F-16, which combines advance(a) computing capabilities for both weapons and avionics in a single high military operation system.Developed by Raytheon (Lockheed Martins F-16 team), it replaces three estimators with one superior system, reduce weight by 55%, volume by 42% and military unit by 32%. What is OMGs MDA? OMG (Object Management Group) since 1989 is a non profit calculator industry consortium. Their board of directors represents most of the organizations that shape, enterprise and internet computing today. Their membership includes hundreds of organizations, most of them representing virtually every large organization in the computer industry and many smaller ones.MDA (Model Driven Architecture) is a modeling standard, which on with UML (Unified modelling Language), enable power ful visual role, execution and sustenance of software and other servees, including IT Systems theoretical account and Business Process Management. When and why was this software developed? The MMC upgrade was a part of the MLU process of the F-16. When plans of replacing the F-16 (in operation since 1979) with its heritor in 1999 stalled, they decided to modernize the aircraft, which became the MLU (Mid Life Update). Part of this modernization process was developing software with cross platform compatibility.The goal should be to provide cross-platform compatibility of Application Software despite any Implementation, or platform specific, changes that is, changes to the hardware Platform, the Software Execution Platform, or the Application Software Interface get out environ The development Process The F-16 MMC team originally used traditional CASE tools with an OO modeling notation to specify the software before manually coding it in Ada (Language extended from Pascal). Whe n they migrated their development to Kennedy Carters iUML tool, they gained the readiness to use a UML action language which made their UML models executable.They could then political campaign their UML models to verify their intended behavior before hand-coding the slaying. More recently they guide used Kennedy Carters iCCG product to specify, in feasible UML, an Ada canon generator which can automatically generate 100% of the Ada implementation. By this means they guarantee that their UML models are entirely platform fencesitter and movable across any future platform. drawframe viable UML Modeling Overview xUML models are a complete representation of the problem space (not a top-level or preliminary design) Modeling is performed using aUnified Modeling Language (UML) representation Modeling makes use of a precise exploit Specification Language (ASL) and is therefore executable (providing early validation of the models) all(prenominal) xUML model is a Platform Independent Model (PIM), that is, completely implementation-independent (i. e. independent of the hardware platform, the software execution platform, and the employment software interface) _ normal Tagging _Overview Whereas xUML modeling is platform- independent, Design Tagging is platform-specific (i. e. pecific to a particular Application Software Interface) Platform-specific design decisions (only those needed to take engrave generation) are made during Design Tagging, and are represented with design tag values that are applied to the xUML models The most standard implementation is always assumed by the grave generator, such that only exceptions moldiness be tagged Design Tagging is overlaid on (not embedded in) the xUML models, such that it may be included or excluded Design Tagging Specifying the PIM to PSM Mapping drawframe Automatic Code Generation OverviewAutomatic code generation is obviously an extension of the code generation technique used for simulation of the eXecutable UML models on the development platform, this extension being for the target (embedded) platform The code generator is developed within the same environment as the coating software using the same eXecutable MDA strategy textlist-item some all implementation-specific design tasks (all but the design decisions represented by design tag values) are performed by the code generator, not the software developers Advantages of the eXecutable MDA ApproachIncreased Quality The majority of software developers are stray from implementation details, allowing them to focus on a thorough analysis of the application space Maintenance of the application fountain code is eliminated, while maintenance of the xUML models is ensured Defect injection (and the resulting rework) is rock-bottom by automating the software phase in which most defects are injected textlist-item Increased Productivity Rework is reduced Early validation through simulation reduces rework textlist-itemhigher(prenominal) quality i mplementation (due to automation) reduces rework Software development span time is reduced by automating the implementation phase Application Software development schedule is reduced by at least 20% The code generator, not each software developer, performs the majority of implementation-specific design tasks 40-60% of physical source code Cross-Platform Compatibility One Application Software xUML Model database may be reused (as is) on any platform for which a mapping is defined (i. e. a code generator is developed) xUML models are compatible with any hardware platform, any Software Execution Platform, and any Application Software Interface xUML models are compatible with any implementation language References Dr P.
