Abstract

In this study, we consider an n-job, m-machine flow shop scheduling problem with decreasing time-dependent job processing times. By the decreasing time-dependent job processing times, we mean that the processing time is a decreasing function of its execution starting time. When some dominant relationships between m-1 machines can be satisfied, we show that the makespan minimization problem can be solved in polynomial time.
