Webmachines into the n-job flowshop sequencing problem for 2-machines and hence allowed Johnson's algorithm to be used for the M-machine problem. The basic feature of Johnson's optimal solution which minimises makespan for the 2-machine sequencing problem' is that jobs with short first operation times are finished early in a sequence and jobs with ... Webmachines and a machine is not kept idle if a job for the machine is ready for processing. Noting that minimizing the makespan is equivalent to minimizing idle time on the last machine, Johnson proposed an algorithm to solve the n/2/F/Cmax problem in O(n log n) time. Johnson further presented an algorithm to solve the
