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...
Bicriteria scheduling of a material handling robot in an m-machine cell to minimize the energy consumption of the robot and the cycle time Gultekin, Hakan; Gürel, Sinan; Taspinar, Rabia (2021-12-01) This study considers a flowshop type production system consisting of m machines. A material handling robot transports the parts between the machines and loads and unloads the machines. We consider the sequencing of the rob...
A heterogeneous fleet liner ship scheduling problem with port time uncertainty Gürel, Sinan (Springer Science and Business Media LLC, 2019-12-01) We deal with a schedule design problem for a heterogeneous fleet liner shipping service under uncertain waiting and handling times at ports. In a liner shipping service, longer than expected waiting and handling times at a...
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 Caglar, Musa; Gürel, Sinan (2019-06-01) Government funding agencies spend significant amounts of R&D funds through funding programs. While allocating funds among sectors or scientific disciplines, the Decision Maker (DM) wants to maximize the total impact by sup...
Robotic cell scheduling considering energy consumption of robot Gültekin, Hakan; Gürel, Sinan; Akhlaghi, Vahid Eghbal (null; 2017-12-08)
Flight Network-Based Approach for Integrated Airline Recovery with Cruise Speed Control ARIKAN, Ugur; Gürel, Sinan; Akturk, M. Selim (2017-11-01) Airline schedules are generally tight and fragile to disruptions. Disruptions can have severe effects on existing aircraft routings, crew pairings, and passenger itineraries that lead to high delay and recovery costs. A re...
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...
