Essays on last mile logistics alliances and the finite horizon joint replenishment problem

The first and second essay in the thesis focus on analyzing and developing mechanisms for implementing collaboration between logistic service providers (LSPs) undertaking last-mile delivery of ecommerce parcels and to share cost savings generated through collaboration between the LSPs. These works...
