Atego launches SysML explorer design tool

Atego Artisan Parasolver

Speeds the exploration of complex SysML systems design alternatives

Atego in Cheltenham has launched an add-on module for its Artisan Studio standards-based, model-driven development tool suite to speed the exploration of different SysML designs.

Artisan Studio ParaSolver speeds up the whole process of exploring complex SysML design alternatives by using SysML parametric models, enabling system engineers to find the best system design quickly and easily with system measures-of-effectiveness (MoEs), such as cost, risk, reliability and performance characteristics and automatically verify design constraints.

“Artisan Studio ParaSolver radically accelerates trade studies,” said Hedley Apperly, Atego’s Vice-President of Product and Marketing.  “It increases design quality assurance while significantly reducing overall design time and costs by providing system engineers with the ability to easily identify the best design compromises and enabling optimal design solutions to be quickly determined.”

The tool connects SysML with solvers like Mathematica and OpenModelica so that equations used for computing MoEs are represented as constraint blocks while SysML parametric diagrams graphically connect system properties and MoEs using these equations. Complex systems can also be decomposed in Artisan Studio using SysML blocks and parts and non-functional requirements refined with constraint blocks so they can be automatically verified by Artisan Studio ParaSolver using the values in the SysML instance models which capture the design alternatives.  By varying input properties, engineers can explore ‘what-if’ scenarios to find best-in-class system alternatives, easily setting up trade-off studies by specifying ranges or discrete sets of property values.   Artisan Studio ParaSolver can also use existing functional models and dispersed model fragments in this process, combining and orchestrating models held externally in MATLAB/Simulink and Mathematica.

“The launch of Artisan Studio ParaSolver reflects our continuing commitment to expanding the power and breadth of our product portfolio so that engineers can more easily meet the difficult challenges involved in designing complex systems,” said James Gambrell, Chairman of Atego.  “Artisan Studio ParaSolver significantly increases the design power of Artisan Studio by providing system engineers with the ability to secure their design decisions, as well as further improving its compatibility with leading third party tools.”
