Architecture

MBASE is a set of guidelines that describe software engineering techniques for the creation and integration of development models for a software project. The models to be integrated extend beyond Product (development) models such as object oriented analysis and design models and traditional requirements models, to include Process models such as lifecycle and risk models, Property models such as cost and schedule, and most notably Success models such as business-case analysis and stakeholder win-win.


Beginning with COCOMO® itself, The COCOMO® Suite is a collection of six COCOMO®-related estimation models in various stages of development. These models attempt to estimate impacts on software system cost, development schedule, and even return on technology investment associated with a variety of software development approaches and processes.  


The Center has been studying software architectures and their impact on the overall life-cycle of software systems. We have devoted a considerable amount of time towards a more comprehensive definition and analysis of software architectures. Follow this link to learn more.


The WinWin research project investigates collaborative and concurrent models for requirements engineering and design of complex software systems. Current development efforts on the project are focused on developing tools and environments that support the collaborative activity.
EDCS uses the WinWin system definition paradigm, the WinWin Spiral Model, and Internet-related software technology to develop distributed collaborative negotiation aids and interactive analysis tools for better and faster definition of complex, evolutionary, software-intensive systems.

SAMSA II (Simulation and Modeling for Software Acquisition)
The focus of the SAMSA technical agenda centers around the development and use of an anticipated near-term technology called the Feasibility Analysis Model (FAM). FAM is envisioned to be a knowledge-based support system that assists senior management in requirer, acquirer, and developer organizations to determine the overall feasibility of a proposed software system architecture, together with the system's requirements, at the earliest possible time, and continuing thereafter.



Reference Architecture for the Standard Satellite Control Segment
The Standard Satellite Control Segment (SSCS) of the U.S. Air Force's Satellite Control Network is defined by high-level requirements that describe a Telemetry, Tracking and Commanding (TT&C) system that performs telemetry processing, satellite commanding, orbit analysis, spacecraft attitude analysis, general mission planning functions, simulation, and management of system resources. We present here a reference architecture that encompases the first five of these functions, with some discussion of the ground system status subfunction of resource managment.
