  1. Systems Thinking and Systems Engineering Model of functions and functional architecture 19 February 2013 Francois Christophe Galina Medyna Eric Coatanéa

  2. From previous sessions

  3. Functional analysis To whom is the system useful? On what is the system acting? Team/ University Fake Fruits and vegetables System:Autonomous robot What is the goal of the product or service? To harvest as much as possible of fruits and vegetables in 90s Needs for a technical system (why is it developed?)

  4. Functional analysis In the functional/logical viewpoint: A requirement can be functional or non-functional? A function can be seen as an INTERFACE between two elements of the environment. In the representation popularized by Pahl and Beitz, a function is an interface between two types of flows.

  5. Representing function as a black-box

  6. Functional representations The IDEF0 black box model
