pSeven 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.

Contents

pSeven comes under the notion of PIDO (Process Integration and Design Optimization) software. Design space exploration functionality is based on the mathematical algorithms of pSeven Core Python library.

pSeven 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's background. The first version of the pSeven Core library was created in association with EADS Innovation Works in 2009. Since 2012, [1] pSeven software platform 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:

Design of experiments allows exploring design space using as small number of observations as possible, enables reliable surrogate-based optimization and generates a training sample for building an approximation model. Design of Experiment.png

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. [3] [4] 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's application areas are different industries such as aerospace, [5] automotive, energy, electronics, biomedical and others.

pSeven has been used for the optimization of layered composite armor in order to reduce its weight [6] and for multidisciplinary and multi-objective optimization of an aircraft family. [7]

HeuristicLab is a software environment for heuristic and evolutionary algorithms, developed by members of the Heuristic and Evolutionary Algorithm Laboratory (HEAL) at the University of Applied Sciences Upper Austria, in Hagenberg im Mühlkreis. HeuristicLab has a strong focus on providing a graphical user interface so that users are not required to have comprehensive programming skills to adjust and extend the algorithms for a particular problem. In HeuristicLab algorithms are represented as operator graphs and changing or rearranging operators can be done by drag-and-drop without actually writing code. The software thereby tries to shift algorithm development capability from the software engineer to the user and practitioner. Developers can still extend the functionality on code level and can use HeuristicLab's plug-in mechanism that allows them to integrate custom algorithms, solution representations or optimization problems.

Predictive engineering analytics (PEA) is a development approach for the manufacturing industry that helps with the design of complex products. It concerns the introduction of new software tools, the integration between those, and a refinement of simulation and testing processes to improve collaboration between analysis teams that handle different applications. This is combined with intelligent reporting and data analytics. The objective is to let simulation drive the design, to predict product behavior rather than to react on issues which may arise, and to install a process that lets design continue after product delivery.

Optimization Systems Associates (OSA) was founded by John Bandler in 1983. OSA produced the first commercial implementation of space mapping optimization to enhance the speed and accuracy of engineering design.

Its products included developments of Bandler's space mapping concept and methodology, which facilitates effective modeling and design optimization of computationally intensive engineering systems.
