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
In this paper we consider a general interval scheduling problem. The problem is a natural generalization of "nding a maximum independent set in an interval graph. We show that, unless P"NP, this maximization problem cannot be approximated in polynomial time within arbitrarily good precision. On the
