Proactive and reactive scheduling in practice
Proactive and reactive scheduling in practice

Summary/Abstract: The paper develops a method proposed earlier of proactive and reactive scheduling [Janczura, Kuchta 2011], in which fuzzy task durations are used, but the resources have to plan their work according to a crisp schedule. In the proposed method for determining the crisp representations three strategies are used. The first strategy is based on the average. The other two are based on optimistic or pessimistic time estimation given by an expert. Human resources are allocated according to the strategy chosen by the project manager. This article proposes an algorithm to support the decision maker in choosing the best strategy to achieve the shortest total duration of the project, where the decision maker chooses a safety level for the project. To illustrate the proposed approach, the algorithm was tested on the data from a real project.
