Abstract: Abstract In this work we propose and analyze a hybrid approach for the multi-mode resource investment problem with tardiness penalty (MRIPT). The MRIPT is a project scheduling problem where, for a given deadline, the objective is to minimize the costs of resources allocated to the project as well as tardiness penalty costs for not respecting the given deadline. For each project activity multiple execution modes with differing resource requirements and durations are given. In particular, we propose a large neighborhood search where destroy operators are applied to a feasible solution to obtain subproblems. These subproblems are solved with MIP-based recreate operators to obtain an improved solution.
