Query: Comments on "A model-based design methodology for the development of
  mechatronic systems"   In the paper by G. Barbieri et al. (Mechatronics (2014),
http://dx.doi.org/10.1016/j.mechatronics. 2013.12.004), a design methodology,
based on the W life cycle process model, is presented and SysML is proposed as
a tool to support the whole development process. In this letter, we discuss the
presented approach, we point out technical errors and raise additional issues
that might help in making the proposed approach applicable.
