A note on “On three-machine flow shop scheduling with deteriorating jobs”

In the recent paper (L. Wang, L.Y. Sun, L.H. Sun, J.B. Wang, On three-machine flow shop scheduling with deteriorating jobs, International Journal of Production Economics 2010, 125, 185-189), a branch and bound algorithm with several dominance properties were presented. In this note, we point out by means of a counter-example that the proposed dominance properties are incorrect and then, we will provide the correct dominance properties.
