Dynamic arc routing problem in road maintenance service with uncertain travel and service times

Abstract

This paper describes a dynamic arc routing problem motivated by daily maintenance operations on road networks to improve the maintenance efficiency. Uncertain service and travel times on road segments are considered and defined using discrete stochastic distribution. An algorithm based on the multiple scenario approach (MSA) is developed to deal with the uncertainty of the network. The MSA scheme is triggered to update the maintenance routing by an event-driven mechanism. The computational experiments demonstrate the effectiveness of the algorithm.
