NEiOptimization

by Noran Engineering

NEiOptimization software is a package for design automation. It performs process integration, automated design of experiments and optimization, sensitivity studies, reliability and robustness assessments on engineered products and processes.

The NEiOptimization software (HEEDS - Hierarchical Evolutionary Engineering Design System) is a package for design automation. It performs process integration, automated design of experiments and optimization, sensitivity studies, reliability and robustness assessments on engineered products and processes. The software can be used to improve any engineering system (structural, thermal, fluid, acoustic, electrical). In structural design applications, for example, it can evolve designs that simultaneously satisfy objectives and meet constraints targets for durability, crashworthiness, stiffness, noise and vibration, mass and cost, manufacturability and reliability.
