The procurement and production planning of horticultural production and retail companies faces many uncertainties, including seasonality and perishability, and is often organized through tactical pre-order and operational re-order planning. We present a stochastic model formulation for this problem ...

We consider the problem of a service provider who offers resources (such as equipment or accommodation) for rent that are substitutable and renewable over time. The provider aims to set static, yet time-dependent prices to maximize revenue while adhering to business-specific pricing rules. As custom...

Software systems supporting sales and operations planning operate on the basis of total production volumes of products. They ensure that production volumes are feasible with respect to the capacity at different production sites without allocating them to individual resources. We consider the prob...

In recent years, the importance of achieving staffing flexibility to balance supply and demand in unpredictable environments, such as hospitals, has grown. This study focuses on shift design with task rotations for a multi-skilled workforce, specifically in service contexts characterized by pronounc...

Drug availability in clinics is essential for patient services, whose demand for medication is uncertain. Thus, clinics must have a variety of drugs available, leading to high inventory holding costs. In Germany, it is common for a larger central clinic to take over the procurement of drugs and dist...

For some NP-hard lotsizing problems, many different heuristics exist, but they have different solution qualities and computation times depending on the characteristics of the instance. The computation times of the individual heuristics increase significantly with the problem size, so that testing al...

Shared Mobility-on-Demand services have the potential to contribute to a more socially and environmentally sustainable mobility provision. However, this potential may not be fully exploited due to possible conflicts with the objectives of the service providers. Thus, political discourses address reg...
