When-to-Revise Against Uncertainty?
Even if a pertinent schedule is initially obtained, its smooth progress will be inhibited by a variety of uncertainties in the real circumstances. It is, as a matter of course, very important to provide against these uncertainties, but at the same time the proactive activities against them have limitations after all. One of the realizable approaches to this kind of problem is to adaptively revise the ongoing schedule or make an adjustment to it on a case-by-case basis. This chapter focuses on the timing to revise or adjust the existing schedule on the condition that the status of the ongoing schedule is monitored. Considered are four types of policies all of which prescribe the timing of revising the ongoing schedule.
