Abstract

In this paper we study the scheduling problem of minimizing makespan on identical parallel machines with time-dependent processing times. We first consider the problem with time-dependent processing times on two identical machines to minimize makespan, which is NP-hard. We give a fully polynomial-time approximation scheme for the problem. Furthermore, we generalize the result to the case with m machines.
