If t(al, 1) 4 t(ai, 1) for all i 5 2, go to step 2; otherwise modify S by bringing the job with minimum processing time to the first sequence position. Step 2: assignment of jobs. Assign job a, to the latest available machine at stage 1 such that no additional idle time is incurred at stage 2.

Idle time between consecutive operations on each machine is not allowed. The objective is minimum makespan. Using the conventional notation to denote scheduling problems, the problem studied here is Fm/no-idle/C max. Our note is organized as follows.
WebMar 1, 2003 · The no-idle permutation flowshop scheduling problem (NIPFSP) extends the well-known permutation flowshop scheduling problem, where idle time is not allowed on the machines. This study proposes a new mixed-integer linear programming (MILP) model and a new constraint programming (CP) model for the NIPFSP with makespan criterion. Webof idle time in the schedule can be advantageous. See [6] for a literature review about scheduling with inserted idle time. The problem parameters for all the formulations studied in the rest of this work are (a) n: the number of jobs, (b) m: the number of machines, (c) p ik: the processing time of job i on machine k, and (d) d i: the due date ...
