The uniform parallel machine scheduling problem with unequal release dates and minimizing total completion time is considered. This problem has been proved to be NP-hard in the strong sense. A new heuristic algorithm (HRS) is proposed and a variable neighborhood search approach (HRS-VNS) is constructed to improve the quality of the HRS solutions. The performance and efficiency of HRS and HRS-VNS are tested on a set of randomly generated instances. The results and analysis of experiments are also given.
