    Pooling Through Lateral Transshipments in Service Parts Systems
    (Elsevier Science Bv, 2012) Savasaneril, Secil; Serin, Yasemin; Satir, Benhur
    We study the inventory management problem of a service center operating in a decentralized service parts network. The service centers collaborate through inventory and service pooling, and through sharing information on the inventory status. Upon demand arrival, a service center may request a part from the other center, in which case a payment is made. Under this competitive and collaborative environment, we first characterize the optimal operating policy of an individual service center. Through computational analysis we identify the conditions under which pooling is most beneficial to the service center, and make an assessment of different pooling strategies which are commonly adopted in practice and in the literature. Finally, we analyze the effect of interaction between the centers on the benefit of pooling. (C) 2012 Elsevier B.V. All rights reserved.

    An Exact Solution Procedure for Multi-Item Two-Echelon Spare Parts Inventory Control Problem With Batch Ordering in the Central Warehouse
    (Elsevier Science Bv, 2010) Tan, Tarkan; Bayindir, Z. Pelin; Topan, Engin; Pelin Bayindir, Z.
    We consider a multi-item two-echelon inventory system in which the central warehouse operates under a (Q, R) policy, and the local warehouses implement basestock policy. An exact solution procedure is proposed to find the inventory control policy parameters that minimize the system-wide inventory holding and fixed ordering cost subject to an aggregate mean response time constraint at each facility.
