Fundamentals of information technology are now part of the training for engineers. The requirements go beyond the basics of programming techniques. Technical products are multidisciplinary complex systems developed by several engineering disciplines. Interdisciplinary collaboration between mechanical engineering, electrical engineering/electronics, and computer science is essential for innovative product development. The book presents the technical application systems that are in constant evolution. Aspiring engineers are introduced to intelligent tools that cover development (Computer Aided Design), calculation and simulation (Computer Aided Engineering), administration (Product Lifecycle Management), as well as visualization. The mechatronic product development process, as a component of systems engineering, is also introduced.
