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

About the Comp some(prenominal) Although they are a global security and information technology company, the majority of Lockheed Martins business comes from U. S incision of Defense and Federal Agencies. In fact, they are the largest provider of IT services, systems integration, and training to the U. S Government. The remaining portion of Lockheed Martins business is comprised of international government and some mercenaryised sales of products, services and programmes. Lockheed Martins operating units are organized into broad business areas Aeronautics $11. billion in 2008 sales includes tactical coursecraft, airlift, and aeronautical explore and using lines of business. Electronic Systems $11. 6 billion in 2008 sales includes missiles and fire control, naval systems, platform integration, simulation and training and energy programs lines of business. Information Systems & Global run $11. 6 billion in 2008 sales includes C4I (stands for Command, Control, Communications, C omputers, and Intelligence), federal services, government and commercial IT solutions.Space Systems $8 billion in 2008 sales includes space launch, commercial satellites, government satellites, and strategic missiles lines of business. Something about the F-16 The Lockheed Martin F-16 Fighting Falcon is a multirole jet fighter aircraft originally developed by General Dynamics for the United States rail line Force. Designed as a lightweight, daytime fighter, it evolved into a successful multirole aircraft. Over 4400 aircraft have been built since production was approved in 1976 and it currently serves in the air forces of 25 nations. About the softwareThe Aeronautics division of LMs, based in Fort Worth, Texas has used the OMGs MDA to develop exercise Software for the F-16 standard relegation Computer. This software is cross-platform compatible and has highly increased productivity and quality. Just as the highly demanding environment of avionics software development and the MM C (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 advanced computing capabilities for both weapons and avionics in a single high performance system.Developed by Raytheon (Lockheed Martins F-16 team), it replaces three computers with one superior system, reducing weight by 55%, volume by 42% and power by 32%. What is OMGs MDA? OMG (Object focusing Group) since 1989 is a non profit computer industry consortium. Their board of directors represents most of the governings 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 puzzleing standard, which along with UML (Unified molding Language), enable powerful visual design, execution and sustainment of software and other processes, in cluding IT Systems Modeling 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 inheritor 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 drawframe The development Process The F-16 MMC team originally used traditional CASE tools with an OO modeling notation to specify the software in the beginning manually coding it in adenosine deaminase (Language extended from Pascal). When they migrated their development to Kennedy Carters iUML tool, they g ained the ability to use a UML action language which made their UML models executable.They could then test their UML models to verify their intended behavior before hand-coding the implementation. More recently they have used Kennedy Carters iCCG product to specify, in viable UML, an Ada ordinance generator which can automatically generate degree Celsius% of the Ada implementation. By this means they guarantee that their UML models are entirely platform independent and portable across any future platform. drawframe eXecutable 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 Action Specification Language (ASL) and is therefore executable (providing early validation of the models) Each xUML model is a Platform Independent Model (PIM), that is, completely implementation-independent (i. e. independent o f the hardware platform, the software execution platform, and the application software interface) _Design Tagging _Overview Whereas xUML modeling is platform- independent, Design Tagging is platform-specific (i. e. pecific to a particular(prenominal) Application Software Interface) Platform-specific design decisions (only those needed to support code 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 code generator, such that only exceptions must 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 simply 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 application software using the same eXecutable MDA strategy text editionlist-item roughly 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 isolated from implementation details, allowing them to focus on a thorough analysis of the application space support of the application source code is eliminated, while maintenance of the xUML models is ensured Defect injection (and the resulting rework) is reduced 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 quality implementation (due to automation) reduces rework Software development span time is redu ced by automating the implementation phase Application Software development schedule is reduced by at to the lowest degree 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.
