In this paper we explore whether the incorporation of systematic time series analyses and mathematical optimization procedures in the practical planning process has the potential to improve production program decisions. The cases of four German cash crop farms are investigated over six planning...

Introduction: Two next-generation pneumococcal conjugate vaccines (PCVs), a 15- and a 20-valent PCV (PCV15 and PCV20), have recently been licensed for use in adults (PCV15: EC decision Oct 14, 2021; PCV20: EC decision Feb 14, 2022). We developed a dynamical transmission model specific for Germany,...
