Free White Paper Highlights Smarter System Development
 TMCnet Contributor
Trade studies are used to help fully explore a design space and ensure that a proposed solution best meets conflicting performance and cost requirements. Many do not know however, that it is possible to analytically and objectively conduct trade studies well before the engineering phase.
Using a model-driven approach and IBM (News - Alert) Rational Rhapsody software, it is possible to determine which solution will best capture stakeholder requirements, while also justifying engineering decisions.
IBM Rational Rhapsody is a visual development environment for systems engineers and software developers creating real-time or embedded systems and software.
A new white paper, “Smarter System Development: A systems engineering trade study to support green initiatives with model-driven development,” describes a multivariable decision problem based upon the selection of a power source for an environmentally conscious but cost-effective family-size vehicle for the European/U.K. marketplace, as an example of how this can work.
The white paper notes that trade study analysis should be used as a means to determine the most appropriate solution to a given problem prior to implementation or development.
“In this paper, we used the weighted objectives method and the Rational Rhapsody toolkit from IBM to analytically and objectively conduct a trade study analysis during the systems engineering process. Our goal was to determine which power source would give us the lowest CO2 emissions and fuel costs for a green family vehicle,” said Graham John Bleakley, PhD, rational software, IBM Software Group.
“Using the Rational Rhapsody tool, we not only accomplished this objective, we did so through modeling, which saves time, energy and—of course—money,” said Bleakley.
The free white paper also covers areas such as identifying key system functions, defining candidate solutions, defining assessment criteria, assigning weights to the criteria, defining utility curves, determining measures of effectiveness and determining a solution. For more, check it out HERE.
