Fig. 1From: An integrated scheduling algorithm for multi-device-processes with the strategy of exchanging adjacent parallel processes of the same deviceSchematic diagram of situation 1: This figure is the schematic diagram of the interchange when the pre- and post-tightening processes are common processes. First cancel the scheduling of process A and then reschedule B, compare the maximum finishing time of all processes of process B in the pre-tightening process set in the process tree with the finishing time of the pre-tightening process on its device, the maximum value is set as the processing start time of process B. Then process A is rescheduled, and the finishing time of process B is taken as the starting time of process ABack to article page
