Note: On the two-machine no-idle flowshop problem

In this short note we study a two-machine flowshop scheduling problem with the additional no-idle feasibility constraint and the total completion time criterion function. We show that one of the few papers which deal with this special problem contains incorrect claims and suggest a way how these claims can be rectified. © 2000 John Wiley & Sons, Inc.
