Tail assignment problem with hour-to-cycle ratio constraints Aydoğan, Çiya; Gürel, Sinan (2025-04-01) Effective management of hour-to-cycle performance is crucial for any aircraft operating under an operating lease contract. This protects an airline from incurring supplemental rental payments that arise from leasing contra...
Energy efficient scheduling of a two machine robotic cell producing multiple part types Aydoğan, Çiya; Gürel, Sinan (2024-01-01) This paper studies robot speed control decisions and the energy consumption objective in a cyclic robotic cell scheduling problem. The study considers a two-machine flow shop cell that produces multiple part types. A robot...
Scheduling a dual gripper material handling robot with energy considerations Gürel, Sinan; Gultekin, Hakan; Emiroglu, Nurdan (2023-04-01) Robotic cells are serial production systems that consist of a number of machines and a material handling robot that transfers parts between the machines. Energy consumption of a robot during its move between two machines c...
Public R &D project portfolio selection under expenditure uncertainty Çağlar, Musa; Gürel, Sinan (2023-01-01) We consider a project portfolio selection problem faced by research councils in project and call-based R &D grant programs. In such programs, typically, each applicant project receives a score value during specially-design...
Energy conscious scheduling of a material handling robot in a manufacturing cell Gürel, Sinan; Akhlaghi, Vahid Eghbal (Elsevier BV, 2019-08-01) In cyclic scheduling of material handling robots in manufacturing cells, a common approach is to minimize the cycle time objective, which is a measure of the throughput of the cell. In a typical robot move cycle, robot mov...
Impact assessment based sectoral balancing in public r&d project portfolio selection problem Gürel, Sinan (null; 2017-09-08) Government funding agencies provide considerable amount of R&D funds through funding programs. While constructing R&D project portfolio, Decision Maker (DM) wants to balance program budget over sectors or scientific discip...
Kamu Ar-Ge Proje Portföy Seçiminde Sektörlere Etki Değerlendirme Temelli Dengeli Bütçe Dağıtımı Gürel, Sinan (2017-07-07) Bu çalışmada kamu Ar-Ge proje portföy seçimi probleminde eldeki bütçenin farklı sektörlere veya bilimsel disiplinlere dengeli dağıtımı problemini ele aldık. Bu problemde ekonomik ve sosyal etkisi yüksek sektörlere daha yük...
Public R&D project portfolio selection problem with cancellations ÇAĞLAR, Musa; Gürel, Sinan (Springer Science and Business Media LLC, 2017-07-01) In this study, we address a public R&D project portfolio selection problem with project cancellations. For several reasons, a funded R&D project may be halted before finishing the planned research. When a project is cancel...
A chance constrained approach for heterogeneous fleet scheduling in liner shipping service Gürel, Sinan (2016-08-30)
An integrated approach for airline scheduling, aircraft fleeting and routing with cruise speed control Gurkan, Huseyin; Gürel, Sinan; Akturk, M. Selim (2016-07-01) To place an emphasis on profound relations among airline schedule planning problems and to mitigate the effect of unexpected delays, we integrate schedule design, fleet assignment and aircraft routing problems Within a dai...
