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, respectively. As a benchmark, we study the centralized system where the manufacturer and the retailer are integrated. We also study an alternative model; i.e., a third party 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. We find that when the manufacturer controls her after-sales channel, she gives away the prod-uct for free and extracts all her profit from the after-sales services. In fact, the extent of the warranty coverage is irrelevant, and does not affect the manufacturer's profit or the consumer surplus. Especially when customers are myopic with very limited foresight into future costs, the manufacturer will prefer to control her after-sales market. From the customer perspective, however, the third party model tends to be the better choice.(c) 2022 Elsevier Ltd. All rights reserved.

After-sales services for durable goods Kirkizoğlu, Zeynep; Karaer, Özgen; Department of Industrial Engineering (2022-9-02) 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...
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...
Price competition between manufacturers selling to a common retailer under stock-out-based substitution Kılıç, Betül Diler; Karaer, Özgen; Bakal, İsmail Serdar (2022-12-01) We consider two partially substitutable products sold through a two-echelon supply chain, consisting of two manufacturers and one retailer. In case of a stock-out in one of the products, that product's demand can spill over to the competing product. We analyze the equilibrium pricing decisions of the manufacturers and ordering decision of the retailer in a three stage dynamic game for a single period. We investigate the effect of spillover rates on equilibrium decisions. We also evaluate the impact of spill...
Joint quantity flexibility for multiple products in a decentralized supply chain Karakaya, Selcuk; Bakal, İsmail Serdar (2013-02-01) In this study, we analyze a decentralized supply chain with a single retailer and a single manufacturer where the retailer sells multiple products in a single period. The products differ in terms of a limited number of features only. The retailer places initial orders based on preliminary demand forecasts at the beginning of the period and has an opportunity to modify its initial order after receiving perfect demand information. However, the final orders of the retailer are constrained by its initial orders...
Development of an AHP based supplier evaluation system: a case study in a Turkish defense firm Kartal, Burak.; Karakaya, Gülşah; Department of Business Administration (2019) Supply chain process is one of the key processes in manufacturing firms which consists of various business entities such as suppliers, manufacturers, distributors, retailers and consumers. In order to establish a sustainable supply chain system, suppliers should be monitored and controlled on a regular basis. Supplier evaluation plays a crucial role to sustain a well-performing supplier pool for large manufacturing firms. To build an effective supplier evaluation system, the set of criteria covering the who...
