Durable goods are products that are designed to be used for an extended period of time and require after-sales activities such as warranty, repair and maintenance. In the first part of this study, we consider a monopolistic durable goods manufacturer that also provides a base warranty and after-sales services to her customers through a designated retailer. The customers are strategic; i.e., they evaluate the total lifecycle cost of the product when making their purchasing decision. However, they can foresee the future costs only to a certain extent. In this setting, we find the manufacturer’s product price decision followed by the spare parts wholesale and retail price decisions made by the manufacturer and the retailer, respectively. As a benchmark, we study the centralized system where the manufacturer and the retailer are integrated. We also study an alternative model, where the manufacturer is not active in the after-sales business and does not offer a warranty, and these services are carried out by an independent retailer. In the second part of the study, we look into downstream competition. The manufacturer and the retailer operate with similar dynamics to the first part, except that the retailer now competes with an independent workshop for after-sales services after the warranty period is over. This competition provides a cheaper alternative to the customers for owning the product, hence changing the strategic decisions of the manufacturer and the retailer. In both parts, we provide managerial insights by studying analytical equilibriums where possible, and by conducting numerical studies otherwise.

After-sales service and warranty decisions of a durable goods manufacturer Kirkizo, Zeynep; Karaer, Özgen (2022-12-01) We study a monopolistic durable goods manufacturer that also provides a base warranty and after-sales services to her customers through a designated retailer. The customers evaluate the total cost of owner-ship of the product when they make the purchasing decision. However, they can foresee the future costs only to a certain extent. In this setting, we find the manufacturer's product price decision followed by the spare parts wholesale and retail price decisions made by the manufacturer and the retailer, re...
Mechanical, thermal and flammability properties of huntite hydromagnesite reinforced polyurethane elastomer Güler, Türkan; Bayramlı, Erdal; Doğan, Mehmet Onur; Department of Polymer Science and Technology (2017) Polyurethane elastomer (Thermoplastic Polyurethane-TPU) has desirable properties for many applications including footwear, packaging, protective coatings, cables, wires and tubes in the mainly automotive and construction industries. Huntite and Hydromagnesite are naturally occurring minerals that has been used as fire retardants commercially since the late 1980’s. The World’s largest reserve of this mineral has been found in Turkey. The main purpose of present work is to investigate the combustion and therm...

Synthetic Lubricants Derived from Plastic Waste and their Tribological Performance Hackler, Ryan A.; Vyavhare, Kimaya; Kennedy, Robert M.; Çelik, Gökhan; Kanbur, Uddhav; Griffin, Philip J.; Sadow, Aaron D.; Zang, Guiyan; Elgowainy, Amgad; Sun, Pingping; Poeppelmeier, Kenneth R.; Erdemir, Ali; Delferro, Massimiliano (2021-01-01) © 2021 Wiley-VCH GmbHThe energy efficiency, mechanical durability, and environmental compatibility of all moving machine components rely heavily on advanced lubricants for smooth and safe operation. Herein an alternative family of high-quality liquid (HQL) lubricants was derived by the catalytic conversion of pre- and post-consumer polyolefin waste. The plastic-derived lubricants performed comparably to synthetic base oils such as polyalphaolefins (PAOs), both with a wear scar volume (WSV) of 7.5×10−5 mm−3....
Sensitivity Analysis of Distortion of Carburized Steel Shafts Using Computer Simulations Yazır, Büşra; Evcil, Elif; Yıldız, Seçil; Davut, Kemal; Şimşir, Caner (null; 2016-12-01) Carburizing and subsequent quenching heat treatments are commonly used industrial processes to improve the properties and performance of steel shafts. Undesired dimensional and shape changes (distortion) related to these treatments are still the most frequent reason for expensive and time consuming corrective operations, low performance during service and even product rejection. The major aim of this study is to identify the suitable control parameters for subsequent optimization of the carburized quenching...
