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 amounts, so that companies have to consider costs related to carbon emissions resulting from their logistic operations as well as direct costs like fuel consumption. To compensate the increase in the cost amounts new approaches need to be developed. One way to achieve increased operational efficiencies under such a problem environment might be collaboration with other companies which also involves a competition on a smaller scale. In our study, we consider a market characterized by uncertain shipment requests where shippers are willing to collaborate for their shipment activities. They also compete for truck space within this collaboration process. We assume that the companies aim to maximize the profit from their shipments. We assume the shippers form a coalition and make dispatch decisions vii jointly. To ensure a fair and stable allocation of the savings we develop allocation schemes that require a low computational effort. We evaluate and compare the schemes based on several criteria.

The price of anarchy in an uncapacitated deterministic shipment consolidation game
Karaahmetoğlu, Cevat Enes; Savaşaneril Tüfekci, Seçil; Yüksel Özkaya, Banu; Department of Industrial Engineering (2022-11-23)
Collaboration of companies for logistics activities result in more efficient use of logistics resources which leads to reduction of logistic costs. In this study, multiple shippers that make shipments from the same origin to the same destination are under consideration. The shipment requests of the shippers arrive over time at a deterministic uniform constant rate and the shippers consolidate their shipments on uncapacitated trucks. The trucks are dispatched at a certain frequency to maximize the profit ga...
Supplier Selection For Assembly Components Under Lead Time Uncertainty
Kürekci, Zeynep; Gürel, Sinan; Department of Industrial Engineering (2022-2)
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 resultin...
Integrating knowledge with suppliers at the R D manufacturing interface
ROSELL, DAVID T; LAKEMOND, NICOLETTE; Wasti Pamuksuz, Syeda Nazlı (Emerald, 2014-02-01)
Purpose - Many manufacturing firms source components and subsystems from suppliers. Consequently, the suppliers' product and manufacturing knowledge is a central concern at the interface between R&D and manufacturing. This paper aims to specifically investigate how supplier knowledge is integrated and what role trust plays in knowledge integration with suppliers at the R&D-manufacturing interface. Design/methodology/approach - The study is based on qualitative case studies of two different collaborations w...
Decentralized inventory planning with transshipments in a multi-project environment
Soylu Nazlı, Duygu; Bakal, İsmail Serdar; Savaşaneril Tüfekci, Seçil; Department of Industrial Engineering (2021-3-17)
Many companies in project-based industries manage their inventories in a decentralized manner on a project-by-project basis. Even if one project has excess supply of a material, the other may have excess demand of it, which increase inventory costs of the company. These costs can be decreased if material transshipments between projects are allowed. In this study, motivated by the defense industry applications in Turkey, we investigate ordering decisions of two different agents, who make inventory decisions ...
A spare parts inventory optimization study in mining
Şenses, Sena; Gölbaşı, Onur; Bakal, İsmail Serdar (2022-1-01)
Spare parts inventory management is of vital importance in maintaining high equipment availability at minimum cost, especially for industries utilizing fully mechanized systems and aiming mass and continuous production such as mining. In this paper, it is intended to solve the spare parts inventory problem of a large-scale mining company operating in Turkey, by proposing a mathematical model to optimize the spare parts provisioning strategy in such a way that the total inventory related cost is minimized.
