A two-stage stochastic programming model for bike-sharing systems with rebalancing

Cavagnini, Rossana; Maggioni, Francesca; Bertazzi, Luca; … - In: EURO journal on transportation and logistics 13 (2024), pp. 1-25

We study the problem of determining the target inventory level of stations in a bike-sharing system, when bikes can be rebalanced later during the day. We propose a two-stage stochastic programming formulation, where the target inventory decisions are made at the first stage, while the recourse...
