This paper mistakenly treats the ‘‘controlling sequence’’ defined
for the first time in Harris and Ioannou ~1998! as a synonym for
the critical path in the traditional critical path method ~CPM!, by
stating that ‘‘the control points in the repetitive scheduling
method ~RSM! are used to define the controlling sequence of
activities, the critical path in a CPM schedule, which in turn determines
the project duration.’’ Yet, the introduction of the ‘‘controlling
sequence’’ and its differentiation from the traditional critical
path is a main contribution of RSM, which should be pointed
out and recognized explicitly. By overlooking this important distinction,
the paper ends with misleading results. Moreover, the
paper identifies critical activities incorrectly, such as in Figs. 5, 7,
13, 15, 20, and 22. Thus, the purpose of this discussion is to
correct these misunderstandings and to clarify the original definitions
of the controlling sequence and critical activities in RSM.
