Dear scheduling researcher, We are delighted to announce the talk given by Sigrid Knust (Uni of Osnabrück). The title is "Synchronous flow shop scheduling problems". The seminar will take place on Zoom on Wednesday, November 23 at 14:00 UTC. Join Zoom Meeting https://cesnet.zoom.us/j/91616587714?pwd=SFJGcnpVbTFSSWFGVWt5WHFwL2xuQT09 Meeting ID: 916 1658 7714 Passcode: 332102 You can follow the seminar online or offline on our Youtube channel as well: https://www.youtube.com/channel/UCUoCNnaAfw5NAntItILFn4A The abstract follows. A synchronous flow shop is a variant of a non-preemptive permutation flow shop where transfers of jobs from one machine to the next take place at the same time. The processing is organized in synchronized cycles which means that in a cycle all current jobs start at the same time on the corresponding machines. Then all jobs are processed and have to wait until the last one is finished. Afterwards, all jobs are moved to the next machine simultaneously. As a consequence, the processing time of a cycle is determined by the maximum processing time of the operations contained in it. Furthermore, only permutation schedules are feasible, i.e., the jobs have to be processed in the same order on all machines. The goal is to find a permutation of the jobs such that the makespan is minimized. Motivated by a practical application in production planning at a company assembling shelf boards for kitchen elements, we investigate different aspects of synchronous flow shop problems. Especially, we consider the situation of dominating machines, additional resources, setup times and leaving machines idle. The next talk in our series will be in January 2023.
