Multi-item Two-echelon Spare Parts Inventory Control Problem with Batch Ordering in the Central Warehouse under Compound Poisson Demand Z. Pelin Bayindir, Department of Industrial Engineering, Middle East Technical University, Engin Topan We consider a multi-item spare part two-echelon 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 of the system; and extend a heuristic and a lower bound proposed under Poisson demand assumption to the compound Poisson setting. In a computational study, we show that the performances of the heuristic, the lower bound and the approximations are quite satisfactory

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....
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.
- Balancing hybrid disassembly lines with stochastic task times

Balancing hybrid disassembly lines with stochastic task times Volkan Gümü¸skaya, Industrial Engineering, Middle East Technical University, F. Tevhide Altekin, Z. Pelin Bayindir Today while the end-of-life products are collected and reprocessed so as to maximize the recovery of the inherent economic and ecologic value, one of the main operations performed is disassembly. Disassembly lines are one of the settings on which collected products can be disassembled in large quantities. In a paced disassembly l...
