The performance of traditional lot sizing heuristics in a disassembly environment Z. Pelin Bayindir, Department of Industrial Engineering, Middle East Technical University, Middle East Technical University, Department of Industrial Engineering, 06531, Ankara, Turkey, bayindir@ie.metu.edu.tr, Tulu Ertem In this study we focus on a disassembly system where there are a number of end-of-life products (root) that can be disassembled to satisfy the demand for their child (leaf) items. The demand for the leaves are assumed to be known over a finite planning horizon. There is a set-up cost for disassembling roots, in addition to unit costs. Leaf item inventory is kept. We propose a two-phase approach that utilizes traditional lot sizing heuristics for determining the type and number of roots to be disassembled. A computational study is carried out to assess the performance of the proposed approach.
