摘要：

The majority of publications in the extensive literature on resource-constrained project scheduling focus on a static deterministic setting for which a so-called baseline schedule is computed prior to project execution. In the real world, however, a project may be subject to considerable uncertainty. During the actual execution of a project, the baseline schedule may indeed suffer from disruptive events causing the actually realized activity start times to deviate from the predicted baseline start times. This presentation focuses on the construction of optimal policies for the RCPSP with stochastic activity durations, meaning that an optimal baseline schedule is selected as well as all optimal continuations in case a disruption occurs in the baseline schedule or in an already adapted schedule. First, we will take a look at the general case and discuss two models that are capable of constructing ‘optimal’ policies in the sense that these are optimal within the set of schedules that are considered. Next, we will consider a serial project scheduling problem of at most four activities, where the durations of the activities can take on two possible durations. For that particular case, we will construct the real optimal policies and we will infer some rules that can be useful in order to construct better schedules for the general case such that the resulting ‘optimal policies’ are improved.
