pSeven is a design space exploration software platform developed by DATADVANCE, extending design, simulation and analysis capabilities and assisting in smarter and faster design decisions. It provides a seamless integration with third party CAD and CAEsoftware tools, powerful multi-objective and robust optimization algorithms, data analysis and uncertainty quantification tools. pSeven comes under the notion of PIDO software. Design Space Exploration functionality is based on the mathematical algorithms of pSeven Core Python library, also developed by DATADVANCE. Design Space Exploration with pSeven allows creating predictive models, integrating CAD/CAE tools, analyze data and models, explore design alternatives and make smart decisions. SmartSelection technology implemented in pSeven automatically selects the most efficient method for a given data or optimization problem that makes advance math easy to use to a wide range of experts.
History
The foundation for the pSeven Core library as pSeven's background was laid in 2003, when the researchers from the Institute for Information Transmission Problems of the Russian Academy of Sciences started collaborating with Airbus to perform R&D in the domains of simulation and data analysis. The first version of pSeven Core library was created in association with EADS Innovation Works in 2009. Since 2012, pSeven software platform for simulation automation, data analysis and optimization is developed and marketed by DATADVANCE, incorporating pSeven Core.
Functionality
pSeven's functionality can be divided into following blocks: Data & Model Analysis, Predictive Modeling, Design Optimization and Process Integration.
Data & Model Analysis
pSeven provides a variety of tools for data and model analysis:
Adaptive DoE with Uniform, Maximum Variance and Integrated Mean Squared Errors Gain - Maximum Variance criteria.
Design of Experiments allows controlling the process of surrogate modeling via adaptive sampling plan, which benefits the quality of approximation. As a result, it ensures time and resource saving on experiments and smarter decision-making based on the detailed knowledge of the design space.
Sensitivity and Dependency Analysis is used to filter non-informative design parameters in the study, ranking the informative ones with respect to their influence on the given response function and selecting parameters that provide the best approximation. It is applied to better understand the variables affecting the design process.
Uncertainty Quantification capabilities in pSeven are based on . They are used to improve the quality of the designed products, manage potential risks at the design, manufacturing and operating stages and to guarantee product reliability.
Dimension reduction is the process of reducing the number of random variables under consideration by obtaining a set of principal variables.
Predictive Modeling
capabilities in pSeven are based on building, exploring and managing approximation models. pSeven incorporates several proprietary approximation techniques, including methods for ordered and structured data, allowing to understand behavior of user's system with minimal costs, replace expensive computations by approximation models and make smarter decisions based on detailed knowledge of the design space.
Design Optimization
algorithms implemented in pSeven allow solving single and multi-objective constrained optimization problems as well as robust and reliability based design optimization problems. Users can solve both engineering optimization problems with cheap to evaluate semi-analytical models and the problems with expensive objective functions and constraints. SmartSelection technique automatically and adaptively selects the most suitable optimization algorithm for a given optimization problem from a pool of optimization methods and algorithms in pSeven.
Process Integration
Process integration capabilities are used to capture the design process by automating single simulation, trade-off studies and design space exploration. For that, pSeven provides tools to build and automatically run the workflow, to configure and share workflows with other design team members, to distribute computation over different computing resources, including HPC. Main process integration tools of pSeven:
