I am searching for a keyword that describes a machine scheduling problem in which machines are allowed to process multiple jobs at a time. Each job requires a given capacity on the machine. At any point in time, the sum of the capacity required by the jobs processed at that time must not exceed a given limit.
Particularly, I am searching for MILP formulations for problems with this property. However, I only find parallel machine scheduling problems in which the processing of only one job at a time is allowed.
