An alternative approach towards dealing with uncertainty in project time analysis

Popis výsledku v původním jazyce

Critical path method is a fundamental tool of time analysis in project planning. Due to its deterministic nature, it does not reflect any aspects of uncertainty that might occur in the actual real-world applications. The ways of embedding uncertainty into mathematical model of project time analysis have been widely used, in its basic form represented by probabilistic approach of PERT or GERT. We introduce an alternative viewpoint on uncertainty appearing in activity duration evaluation. First, the stated problem is formulated as a longest path problem in directed acyclic graph in the form of mixed integer linear program. Further on, we take an advantage of two different robust formulations that allow to identify critical scenarios in case any deviations from deterministic values of activity durations should appear. It turns out that different concepts of robustness must be used depending whether the duration of an activity was prolonged or contracted. The resulting scenarios show the worst-case situa
