Allahverdi et al. 1999). Hall and Sriskandarajah (1996) gave a survey of machine
scheduling problems with blocking and no-wait in processes. In addition, to a review
of the computational complexity of a wide variety of no-wait and blocking scheduling
problems, they described several well-documented applications of no-wait and
blocking scheduling models and illustrated some ways in which the increasing use of
some manufacturing methods gives rise to other applications. The no-wait flowshop
problems have also been concentrated in much research regarding different criteria
(e.g. Bertolissi 2000, Aldowaisan and Allahverdi 2004, passim).
