We consider a joint manufacturing / remanufacturing environment with remanufacturing yield loss. Demand and return follow independent stationary Poisson processes. Returns can be disposed oﬀ upon arrival to the system. Manufacturing and remanufacturing operations performed in the same facility at exponential rates. Yield information becomes available after remanufacturing. Demands that are not directly satisﬁed are lost. We investigate what inventories to consider when making production and disposal decisions, with the objective of maximizing the long-run average expected proﬁt. Four diﬀerent policies are compared that base disposal decisions on either the local (returns) inventory or the global inventory, and production decisions on either the local (serviceable) inventory or the global inventory. By modelling the system as a Markov process, expressions for the proﬁt associated with each policy are derived. An extensive numerical study shows that it is always optimal to base disposal decisions on the local inventory and production decisions on the global inventory within the parameter sets considered. A sensitivity analysis reveals further insights.

Analyzing the Effects of Inventory Cost Setting Rules in a Disassembly and Recovery Environment Akcali, Elif; Bayındır, Zeynep Pelin (null; 2005-10-15) We consider a salvaging facility that satisfies the demand for remanufactured parts that can be recovered from the end-of-life products. One of the difficulties faced in planning for such a system is the determination of the opportunity cost associated with carrying recovered parts inventory. In this study we investigate the effect of different rules to determine this opportunity cost on the performance of the system. The performance of several different rules is assessed by a computational study under a pr...
Experimental determination of tool wear in routing and trimming of CFRP composites Peker, Zühal; Akkök, Metin; Kılıç, S. Engin; Department of Mechanical Engineering (2015) In order to fulfill growing demand for lighter aircraft, Carbon fiber reinforced polymers (CFRP) have been developed, which differ from metals with regards to their machinability characteristics. The main problem in machining process is the damage caused by delamination of CFRP materials which need to be both cut and shorn of fibers at the same time, since they are remarkably abrasive in nature. This research aims at accessing the most appropriate cutting condition with less tool wear in routing and trimmin...
Assessment of different finite element modeling techniques on delamination growth in advanced composite structures Uçak, İbrahim; Parnas, Kemal Levend; Department of Mechanical Engineering (2012) Virtual crack closure technique (VCCT) is commonly used to analyze debonding/delamination onset and growth in fiber reinforced composite assemblies. VCCT is a computational fracture mechanics based approach, and is based on Irwin’s crack closure integral. In this study, the debonding/delamination onset and growth potential in a bonded fiber reinforced composite skin-flange assembly is investigated using the VCCT. A parametric finite element analyses is conducted. The finite element analyses results are comp...
Examination of the effects of change in global metal prices on Turkish basic metal production and exportation Balıkçıoğlu, Cem; Gaygısız Lajunen, Esma; Department of Economics (2018) The basic metal production industry constitutes up 11% of Turkish manufacturing industry which makes it the second largest industry in manufacturing after food manufacturing with 15.6%. Basic metal production is the second largest industry for Turkish export and import, with 11-13% and 11-14% share respectively. However, the literature lacks studies in terms of the effects of change in basic metal prices on basic metal production industry in Turkey. The thesis contributes to literature by explaining the eff...
Using cost of software quality for a process improvement initiative Demirörs, Onur; Yildiz, O; Guceglioglu, AS (2000-09-07) Process improvement in manufacturing sector traditionally starts with calculation of Cost of Quality. Cost of Quality calculation enables identification of the weakest links of the process that requires immediate attention, prioritization of improvement tasks and establishment of a baseline for these tasks. In the software field, process improvement initiatives usually, leave out the cost of quality calculations. In this paper, we report a case study on the utilization of Cost of Software Quality as an init...
