Planning and modeling the dismantling of nuclear facilities with consideration of uncertainties. An example for the planning of megaprojects

Megaprojects, such as the dismantling of nuclear facilities, often have cost overruns and longer than planned execution times. The reason for that is, amongst others, an insufficient planning. In this work, a planning tool for megaprojects was developed, which exemplarily takes into account the requirements of nuclear decommissioning projects. The goal of the planning is the identification of a plan on operational level, with minimal costs and that considers uncertainties.
