Supplied components constitute a great majority of companies’ total cost and supplier selection is one of the key operations of supply chain management in the competitive world. In this study, our main concern is to start assembly processes of an aircraft company at the planned starting date by receiving components that are required for each process on time. We decide on which components will be ordered from which suppliers under scenario based supplier lead times. The aim is to minimize total cost resulting from penalty costs of assembly processes, holding and procurement costs of components. We propose a linear mixed integer stochastic programming model to solve the problem. Also, we propose a supplier selection algorithm to solve large instances of the problem in reasonable computational times. We conduct an experimental study and examine the performance of the mathematical model and the algorithm.

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...
A cooperative shipment consolidation game with emission considerations Keven, Halit.; Savaşaneril Tüfekci, Seçil; Department of Industrial Engineering (2020) Logistic operations constitute one of the most significant cost components for many companies. Furthermore, these activities have turned out to be one of the main causes of carbon emissions in the world. The carbon emission issue has been under the spotlight in many countries due to the rising concerns about global warming which brought about new regulations. Large majority of these regulations tend to increase the total costs of logistic operations by a variable factor directly related to carbon emission a...
Supplier involvement in automotive component design: Are there really large US Japan differences? Liker, JK; Kamath, RR; Wasti Pamuksuz, Syeda Nazlı; Nagamachi, M (Elsevier BV, 1996-01-01) Typical descriptions of Japanese supplier management portray first-tier suppliers as partners in product development from the early concept stages of design, whereas US first-tier suppliers are provided detailed specifications and blueprints and build to print. This paper examines US/Japan differences in supplier involvement in design based on a 1993 survey of 143 Japanese and 189 US automotive component suppliers. The focus is on the relationships between Japanese component suppliers and their largest Japa...
Bir Savunma Sanayi Şirketinde Malzeme Envanter Yönetim Sisteminin Yeniden Tasarlanması Karabaş, Tolga; Meral, Fatma Sedef; Özdemir, Rüstem Ozan; Nartok, Yusuf Mahir; Karaaslan, Mert (2017-12-01) Bu çalışmada, bir savunma sanayi şirketindeki satın alınan malzemelerin envanter yönetim sistemi ve bu sistemdeki problemler ele alınmıştır. Proje kapsamında ilgilenilen sistem, malzeme taleplerinin açılmasından malzemelerin üretim atölyelerine aktarılmasına kadar geçen süreçleri içermektedir. Uygun zamanda ve miktarda tedarik edilen malzemeler, sözleşme üzerine üretim yapan şirket için hayati önem arz etmekte ve tedarikteki olası gecikmeler şirket için prestij kaybının yanı sıra büyük maddi yük oluşturabil...
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...
