| Abstract: | Today, worldwide far more than 100 nuclear power plants, which have been decommissioned in the recent years, are waiting for
their complete dismantling. Since the dismantling of a single reactor causes costs of up to one billion Euros and lasts up
to 15 years, the elaboration of a scheduling approach helping to optimize the net present value of a dismantling project seems
to be worthwhile. In this paper we present a resource-constrained project scheduling approach optimizing the total discounted
disbursements of dismantling a nuclear power plant. For the corresponding NP-hard optimization problem, we introduce an appropriate
project scheduling model with minimum and maximum time lags, renewable and cumulative resources as well as multiple execution
modes. To solve this model, we introduce a relaxation-based enumeration approach that delivers optimal solutions for problem
instances containing up to 50 activities. |
