In this paper, given a path G with n vertices v1; v2; : : : ; vn and m identical vehicles, we consider a scheduling problem of the vehicles on the path. Each vertex vj in G has exactly one job j. Any of the n jobs must be served by some vehicle. Each job j has a release time rj and a handling time h
