Forecasting warranty claims for month in services groups in automotive sector
Teköz, Begüm; Yozgatlıgil, Ceylan; Taşkaya Temizel, Tuğba; Department of Statistics (2022-8)
Forecasting claim rate under warranty allows companies to optimize their production processes, reduce warranty costs and maintain customer satisfaction. In the case of a production crisis, the poor performance of the claim rate forecast negatively affects business processes. This thesis aims to improve the business processes of many departments, including production, research and development, quality, and after-sales, by forecasting the number of monthly claims in each service group. In this study, warranty...
Processing and assessment of aluminum ceramic fiber reinforced aluminum metal matrix composite parts for automotive and defense applications
Türkyılmaz, Gökhan; Kalkanlı, Ali; Department of Metallurgical and Materials Engineering (2009)
The aim of this study was to produce partially reinforced aluminum metal matrix composite components by insertion casting technique and to determine the effects of silicon content, fiber vol% and infiltration temperature on the mechanical properties of inserts, which were the local reinforcement parts of the components. Silicon content of alloys was selected as 7 wt% and 10 wt%. The reinforcement material, i.e. Saffil fiber preforms, had three different fiber vol% of 20, 25 and 30 vol% respectively. The inf...
An empirical study on early warning systems for banking sector
Boyraz, Mustafa Fatih; Gaygısız Lajunen, Esma; Department of Economics (2012)
Early Warning Systems (EWSs) for banking sectors are used to measure occurrence risks of banking crises, generally observed with a rundown of bank deposits and widespread failures of financial institutions. In countries with a small number of banks, for example Turkey with 48 banks (BDDK, 2011), every bank may be considered to have a systematic importance since the failure of any individual bank may carry a potential threat to lead to a banking crisis. Taking into account this fact the present study focuses...
Development of three way catalytic converter for automotive exhaust gas
Bayram, Bilal; Külah, Görkem; Önal, Işık; Department of Chemical Engineering (2021-7-9)
In this study, a novel perovskite-based three-way catalyst (LaFe0.57Co0.37Pd0.06O3/Ce0.8Zr0.2O2/Al2O3) with high performance, thermal stability and SO2 poisoning resistance was developed. The performance of the developed catalyst was compared to a standard catalyst based on dispersed metal (Pd/Rh/ Ce0.8Zr0.2O2 / Al2O3). Performance evaluations were carried out in a dynamic activity test system that simulates redox fluctuations in the exhaust of gasoline engines. ICP-OES, BET surface area, X-ray diffraction,...
Assessment of the best available wastewater management techniques for a textile mill: cost and benefit analysis
Doğan, Buğçe; Yetiş, Ülkü; Department of Environmental Engineering (2008)
The Integrated Pollution Prevention and Control (IPPC) Directive from the European Union strives to achieve a high level of environmental protection by preventing or reducing the pollution emanating from industrial installations directly at the source. The Directive implies that the emission limit values should be set in accordance with each industry’s Best Available Techniques (BAT). In the present study, water recovery and wastewater treatability alternatives developed beforehand were evaluated towards th...
