Two powerful and versatile code packages (Agros Suite and Ārtap) are presented for design and optimization of technical devices and systems. Agros Suite represents an environment for numerical solution of systems consisting of partial differential equations (PDEs) of the second order by a higher-order finite element method with a lot of further advanced features such as full adaptivity and selected optimization techniques. Ārtap is a robust design optimization toolbox that provides a simple and efficient programming environment for a wide-range of optimization methods, integrated and external PDE solvers and well-established machine learning tools. Both packages are described in a sufficient detail and their power is illustrated with solution of three problems from the domain of technical sciences.

介绍了两个功能强大且用途广泛的代码包（Agros Suite和Ārtap），用于设计和优化技术设备和系统。Agros Suite通过高阶有限元方法代表了由二阶偏微分方程（PDE）组成的系统的数值求解环境，具有许多进一步的高级功能，例如完全自适应性和选定的优化技术。Ārtap是一个强大的设计优化工具箱，它为各种优化方法，集成的和外部的PDE求解器以及完善的机器学习工具提供了简单有效的编程环境。对这两个软件包进行了足够详细的描述，并通过解决技术科学领域的三个问题来说明它们的功能。
