Single CNC machine scheduling with controllable processing times to minimize total weighted tardiness

Akturk, M. S.; Ilhan, T. (Elsevier, 2011)

Advanced manufacturing technologies, such as CNC machines, require significant investments, but also offer new capabilities to the manufacturers. One of the important capabilities of a CNC machine is the controllable ...
A strong conic quadratic reformulation for machine-job assignment with controllable processing times

Aktürk, M. S.; Atamtürk, A.; Gürel, S. (Elsevier, 2009)

We describe a polynomial-size conic quadratic reformulation for a machine-job assignment problem with separable convex cost. Because the conic strengthening is based only on the objective of the problem, it can also be ...
Two-machine flowshop scheduling with flexible operations and controllable processing times

Uruk, Z.; Gultekin H.; Akturk, M. S. (2013)

We consider a two-machine flowshop scheduling problem with identical jobs. Each of these jobs has three operations, where the first operation must be performed on the first machine, the second operation must be performed ...
