pSeven Desktop is a design space exploration (DSE) software platform that was developed by pSeven SAS that features design, simulation, and analysis capabilities and assists in design decisions. It provides integration with third-party CAD and CAE software tools; multi-objective and robust optimization algorithms; data analysis, and uncertainty quantification tools.

pSeven Desktop falls under the category of PIDO (Process Integration and Design Optimization) software. Design space exploration functionality is based on the mathematical algorithms of pSeven Core (formerly named MACROS) Python library.

pSeven Desktop workflow engine and algorithms from pSeven Core laid the foundation for the development of pSeven Enterprise, a cloud-native low-code platform used for engineering automation.

History

In 2003, researchers from the Institute for Information Transmission Problems started collaborating with Airbus to perform R&D in the domains of simulation and data analysis using the pSeven Core library as pSeven Desktop's background. The first version of the pSeven Core library was created in association with EADS Innovation Works in 2009. Since 2012,OraResearch, [http://oraresearch.com/2015/02/design-space-exploration-industry-timeline/#more-908 Design Space Exploration Industry Timeline] pSeven Desktop for simulation automation, data analysis, and optimization has been developed and marketed by pSeven SAS, incorporating pSeven Core.

Functionality

= Data and model analysis =

pSeven provides a variety of tools for data and model analysis:

  • The design of experiments allows controlling the process of surrogate modeling via an adaptive sampling plan.
  • Sensitivity and Dependence analysis are used to filter non-informative design parameters in the study, ranking the informative ones regarding their influence on the given response function and selecting parameters that provide the best approximation.
  • Uncertainty quantification capabilities in pSeven are based on OpenTURNS library.
  • 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 Desktop incorporate several proprietary approximation techniques, including methods for ordered and structured data, replacing expensive computations with approximation models.Burnaev E., Prikhodko P., Struzik A., [https://www.pseven.io/assets/files/publications/eucass2013_-_struzik_-_paper_-_issue_a-1.pdf "Surrogate models for helicopter loads problems"], Proceedings of 5th European Conference for Aerospace Science"

= Optimization =

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 semi-analytical models and problems with expensive (in terms of CPU time) objective functions and constraints.F. Gubarev, V. Kunin, A. Pospelov, "Lay-up Optimization of Laminated Composites: Mixed Approach with Exact Feasibility Bounds on Lamination Parameters"Dmitry Khominich, Fedor Gubarev, Alexis Pospelov, [https://www.pseven.io/assets/files/publications/IFORS_CONFERENCE_DMITRY_KHOMINICH_v1.pdf "Shape Optimization of Rotating Disks"], 20th Conference of the International Federation of Operational Research Societies, 2014

The SmartSelection adaptively selects the optimization algorithm for a given optimization problem.

= Process integration =

pSeven provides tools to build and automatically run the workflow, to configure and share library of workflows and to distribute computation, including HPC. The main process integration tools of pSeven:

Applications

pSeven Desktop's application areas are different industries such as aerospace,[http://www.airbus.com/presscentre/pressreleases/press-release-detail/detail/airbus-achieves-multi-objective-optimization-of-its-aircraft-families-with-datadvances-macros/ Airbus achieves multi-objective optimization of its aircraft families with pSeven Core (ex Macros) software] automotive, energy, electronics, biomedical and others.
