In this paper, we discuss the convergence of two time window discretization methods for vehicle routing problems with time windows. The first method provides a feasible solution for the minimization problem while the second, newly developed by the authors, provides a lower bound. Analysis shows...

This assignment problem is investigated in several steps. First, a myopic deterministic version is studied in which travel time, service time and the demands are fixed. A new non-decreasing partitioning scheme to deal with time window constraints for this problem is developed. A feasible option...

Transportation service subcontracting is becoming an effective means of business for many leading carriers to maintain their market dominance and profitability. This research is based on an outsourcing practice in one of the few largest limousine fleet companies in the US, whose (mostly advance)...
