MesoMORPH: Meso-Adaptation of SystemsWelcome to the home page for DARPA DASADA Project "Meso-Adaptation of Systems". Take a look at What's New in our web. What is Meso-Adaptation?As the Department of Defense becomes more reliant on computing technology to support all of its mission-critical and support functions, the risk grows that a future legacy of monolithic software applications and systems will be increasingly difficult to modify and adapt to rapidly changing needs. Computer systems are more complex than ever even as research and technology development efforts strive to make them more accessible and adaptable to a growing and increasingly diverse set of end-users. While mission-critical applications warrant the need for training and special skills, computing technology is pervading so many everyday activitites in the military, administration, business, and even domestic spheres that people with widely differing cultural and educational backgrounds, work roles and authorities, and physical and cognitive capabilities are called on to interact with computer-based systems through special-purpose equipment, general-purpose computer peripherals, and hand-held and wearable devices. Such trends are accelerating the need for responsive, flexible and adaptable software without sacrificing the reliability and integrity that we expect from carefully engineered systems. We are proposing to develop and integrate technologies for meso-adaptation, a form of system adaptation intermediate in scope, timescale and difficulty between the traditional goals of enhancement and maintenance through global, assured but unresponsive software engineering processes, and the more recent trend in user customization and automated adaptation, which are very rapid, but narrow in scope and uncontrollable at the system level. Meso-adaptation works at the level of user conceptual models, reconfigurable and replaceable interfaces and policies, and reconfigurable components. It requires some skill and training from a change administrator but that role more closely resembles operations management and maintenance than engineering design or end-user fine-tuning. Recent research by the investigators and others in the recently completed EDCS effort as well as ongoing work will be adapted for meso-adaptation. In addition, new techniques will be developed for analysis of conceptual model variance formal assessment of adaptability. The project will result in a software technology for supporting meso-adaptation, MesoMorph, which will provide adaptability and similarity gauges for change administrators. Goals of Meso-AdaptationMesoMorph addresses the design, coordination and validation of adaptations, with an emphasis on their design:
What's NewThe following is a list of recent additions to our web. Whenever we publish a paper, write a specification, submit a status report, or add anything else to our web, we'll put a notice here. Every month we'll remove the oldest items. The most recent changes are listed first, and each item is linked to the page with the updated content. July 00
