Abstract:
In this paper, inventory control problem in goods distribution networks with non-negligible transshipment
delay is addressed. In contrast to the majority of earlier approaches, system modeling and policy design do
not assume simplified system structure, such as a serial, or a tree-like one. The network nodes, in addition to
satisfying market demand, answer internal requests with delay spanning multiple periods. The stock in the
network is refilled from uncapacited outside sources. A dynamic model of the considered class of goods
distribution systems is constructed and a new inventory policy is formulated. The proposed policy shares
similarity with the classical order-up-to one, yet provide improved performance owing to the networked
perspective assumed in the design process.
