The IJPME Editorial Committee and the CIGIP members are deeply sad by the death of our colleague and friend Dario Franco on November 20th, 2013 in Valencia (Spain). Dario developed an important activity in research and teaching in the Universitat Politècnica de València. Those of us, who had the luck of knowing him, will also miss his extraordinary human qualities and friendship. Dario, you will always be in our hearts. 1Int. J. Prod. Manag. Eng.
