Atego has launched Artisan Studio ParaSolver, a new add-on module for its Artisan Studio standards-based, model-driven development tool suite.

Artisan Studio ParaSolver speeds exploration of complex SysML design alternatives through the execution of SysML parametric models, enabling optimal system design solutions to be determined quickly and easily. Artisan Studio ParaSolver achieves this by enabling system engineers to calculate system measures-of-effectiveness (MoEs), such as cost, risk, reliability, and performance characteristics and automatically verify design constraints.

Artisan Studio ParaSolver connects SysML with solvers like Mathematica and OpenModelica. 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 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 leverage the power of existing functional models and dispersed model fragments in this process, combining and orchestrating models held externally in MATLAB/Simulink and Mathematica.

According to James B. 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."
