  2. 1. An Integrated Approach towards Model-Based Mechatronic Design

    Author : Ahsan Qamar; Jan Wikander; Hans Vangheluwe; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Mechatronics; mechatronic design; development process; conceptual design; model-based systems engineering MBSE ; model integration; SysML; model-driven engineering; consistency; Industrial engineering and economy; Industriell teknik och ekonomi; Software engineering; Programvaruteknik; Systems engineering; Systemteknik;

    Abstract : Mechatronic design is an enigma. On the one hand, mechatronic products promise enhanced functionality, and better performance at reduced cost. On the other hand, optimizing mechatronic design concepts is a major challenge to overcome during the design process. READ MORE

  4. 2. Hierarchical Concurrent Systems from a Model-Oriented perspective

    Author : Daniel Einarson; Data Vetenskap; []

    Abstract : Real world systems are normally considered as hierarchically organized, for example, we see those as hierarchies of systems including subsystems. Examples on this can be seen in organizations where people act in environments and carry within themselves their own internal subsystem of thinking processes. READ MORE
