Integrating Genetic Algorithm, Tabu Search Approach for Job Shop Scheduling [PDF]

open access: yesIJCSIS June 2009 Issue, Vol. 2, No. 1, 2009
This paper presents a new algorithm based on integrating Genetic Algorithms and Tabu Search methods to solve the Job Shop Scheduling problem. The idea of the proposed algorithm is derived from Genetic Algorithms. Most of the scheduling problems require either exponential time or space to generate an optimal answer.

ESTIMATION OF JOB COMPLETION TIMES IN A DYNAMIC SHOP JOB BASED ON STATIC JOB SHOP SOLUTION

open access: yesIFAC Proceedings Volumes, 2007
Abstract We investigate the temporal behaviour of completion time estimates derived from scheduling algorithms that are based on the set of already known and accepted orders (static job shop problem). In a dynamic job shop environment, these estimates change over time, typically increasing.

AAPM‐RSS Medical Physics Practice Guideline 9.b: SRS‐SBRT

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract The purpose of this Medical Physics Practice Guideline (MPPG) is to describe the minimum level of medical physics support deemed prudent for the practice of linear‐accelerator, photon‐based (linac) stereotactic radiosurgery (SRS), and stereotactic body radiation therapy (SBRT) services.

AAPM Medical Physics Practice Guideline MPPG 17.a: Quality management for mammography review workstation displays

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract The Mammography Quality Standards Act (MQSA) sets quality standards for displays used to interpret mammography images. With the shift to digital mammography and the widespread use of remote reading workstations (RWS), updated quality management (QM) programs are needed to ensure consistent image presentation and accurate interpretation.

Open shop scheduling games [PDF]

open access: yesarXiv, 2019
This paper takes a game theoretical approach to open shop scheduling problems with unit execution times to minimize the sum of completion times. By supposing an initial schedule and associating each job (consisting in a number of operations) to a different player, we can construct a cooperative TU-game associated with any open shop scheduling problem ...

Commissioning of a motion management system for a 1.5T Elekta Unity MR‐Linac: A single institution experience

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose This work describes a single institution experience of commissioning a real‐time target tracking and beam control system, known as comprehensive motion management, for a 1.5 T Elekta MR‐Linac. Methods Anatomical tracking and radiation beam control were tested using the MRI4D Quasar motion phantom.
