Flowshop with no idle machine time allowed
Websame machining speed. The idle time for each machine is shown in constraint (9). It is important to remember that idle time exists only at the start and end of the delay; there is no idle time between jobs. Constraint (10) is a total energy consumption calculation. Constraints (11), (12), and (13), respectively, ensure that no idle time WebNov 1, 2005 · For the problem with both no-wait and no-idle constraints, Wang et al.

This study proposes a new mixed-integer linear programming (MILP) model and a new constraint programming (CP) model for the NIPFSP with makespan criterion.
Webfor the general two-machine flowshop problem for sequence-dependent setup times. Under the no-idle constraint, machines work continuously without idle intervals, that is, machines should not remain idle once they start processing the first job. The no-idle constraint arises in real-life situations, when machines may be rented to complete an ...
