We investigate a reverse supply chain consisting of a collector and a remanufacturer in a single-period context. Both the quantity of re- turns and demand for remanufactured products are price-sensitive. The quality of returns is uncertain and revealed by an inspection process. We assume two quality classes, and the cost of remanu- facturing depends on the quality class. In this setting, we develop models to determine the optimal acquisition fee for the returns and the selling price for remanufactured products, and we explore the effects of decentralization and advance quality information.

Centralization and advance quality information in remanufacturing Ünal, Mürüvvet; Bayındır, Zeynep Pelin; Department of Industrial Engineering (2009) In this study, value of quality information and the e ects of centralization are investigated for a reverse supply chain consisting of a remanufacturer and a collector. Used products are collected and inspected to classify them into quality groups, then they are remanufactured to meet the demand of remanufactured products. The supply of collected products and demand of remanufactured products are both price-sensitive. The uncertain quality of the collected products is revealed by an inspection process. Two ...
Multi-Item Two-Echelon Spare Parts Inventory Control with Batch Ordering in the Central Warehouse Tan, Tarkan; Bayındır, Zeynep Pelin; Topan, Engin (null; 2009-10-24) 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. The objective is to find the policy parameters that minimize the system-wide inventory holding and ordering costs subject to an aggregate mean response time constraint at each facility. We propose different heuristics based on Lagrangean relaxation and sequential determination of policy parameters, and discuss their performances.
Heuristics for multi-item two-echelon spare parts inventory control subject to aggregate and individual service measures Topan, Engin; Bayındır, Zeynep Pelin; Tan, Tarkan (Elsevier BV, 2017-01-01) We consider a multi-item two-echelon spare parts inventory system in which the central warehouse operates under a (Q, R) policy and local warehouses implement (S-1,S) policy. The objective is to find the policy parameters minimizing expected system-wide inventory holding and fixed ordering subject to aggregate and individual response time constraints. Using an exact evaluation we provide a very efficient and effective heuristic, and also a tight lower bound for real-world, large-scale two-echelon spare part...
Multi-item two-echelon spare parts inventory control problem with batch ordering in the central warehouse under compound Poisson demand Topan, E; Bayındır, Zeynep Pelin (Informa UK Limited, 2012-8) We consider a multi-item two-echelon spare part inventory system in which the central warehouse operates under an (nQ, R) policy and the local warehouses implement order-up-to S policy, each facing a compound Poisson demand. The objective is to find the policy parameters minimizing expected system-wide inventory holding and fixed ordering costs subject to an aggregate mean response time constraint at each warehouse. In this paper, we propose four alternative approximations for the steady state performance o...
Multi-Item Two-Echelon Spare Parts Inventory Control Problem with Batch Ordering in the Central Warehouse Topan, Engin; Bayındır, Zeynep Pelin; Tan, Tarkan; Department of Industrial Engineering (2010) In this dissertation, we consider a multi-item two-echelon inventory distribution system in which the central warehouse operates with (Q, R) policy, and each local warehouse implements base-stock policy. The objective is to find the policy parameters minimizing the relevant system-wide costs subject to an aggregate mean response time constraint at each facility. We first propose an exact solution procedure based on a branch-and-price algorithm to find the relevant policy parameters of the system considered....
