Approximating the k-traveling repairman problem with repairtimes Raja Jothia1 Balaji Raghavacharib a National Center for Biotechnology Information National Library of Medicine National Institutes of Health Bethesda MD 20894 USA b Department of Computer Science University of Texas at Dallas Richardson TX 75080 USA Accepted 30. 01112007 We consider the k-traveling repairmen problem also known as the minimum latency problem to multiple repairmen. For this reason it might not be worth servicing all the customers and the visit of each location is.

The TRP belongs to the Vehicle Routing Problems and is related in particular to the VRP with Time windows. We also prove that a similar result cannot hold for the Euclidean plane. The waiting time of a customer v at position i in given as input a metric d on a set of vertices V and the optimal tour M LT1 is lower-bounded by the a special vertex s V which will be the starting cost.

We consider the k-traveling repairman problem a generalization of the metric traveling repairman problem also known as the minimum latency problem to multiple repairmen. Informally in the k-traveling repairman problem they are given that there are k repairmen at a common depot s and n customers sitting in some metric space. 13092019 The resulting problem called weighted k-traveling repairman problem wkTRP is a generalization of the well-known traveling repairman problem and can be used to model a variety of real-world applications.

There are however significant differences such as large service times and parts inventory.
