讲座摘要：Collaboration in Logistics has been associated with several stakeholders sharing their resources for a common benefit. In this presentation, we discuss a different perspective: facilities in a production and distribution system held by the same enterprise cooperate when that can result in overall savings to the entire system. This is accomplished by having facilities with surplus capacity or production supporting those facing shortage by transferring part of that capacity/production. Such a transfer incurs a cost that may easily compensate for installing new facilities or paying extra transportation costs. Mixed-integer optimization models are discussed. A distinction is made between the case in which the triangle inequality holds for the transfer costs and the case in which it does not. Different compact models are compared. They are enhanced with valid inequalities that are separated in a branch-and-cut procedure. A comprehensive computational study involving several hundreds of instances shows the value of transferring capacities. Overall, this work investigates a problem at the core of more comprehensive models emerging in logistics network design.
