Vehicle-routeing with time windows and time-varying congestion

This paper discusses vehicle-routeing and scheduling problems subject to time window restriction and time-varying traffic congestion. Time-varying congestion increases the complications of the problems and, in fact, makes it challenging even to find feasible solutions. Numerous heuristics have been developed …

Shortest-Path and Minimum-Delay Algorithms in Networks with Time-Dependent Edge-Length

In this paper the shortest-path problem in networks in which the delay (or weight) of the edges changes with time according to arbitrary functions is considered. Algorithms for finding the shortest path and minimum delay under various waiting constraints are …

TIME-DEPENDENT TRAVELING SALESMAN PROBLEM AND ITS APPLICATION TO THE TARDINESS PROBLEM IN ONE-MACHINE SCHEDULING.

The time-dependent traveling salesman problem may be stated as a scheduling problem in which n jobs have to be processed at minimum cost on a single machine. The set-up cost associated with each job depends not only on the job …
