Bike-sharing systems allow people to rent a bicycle at one of many automatic rental stations scattered around the city, use them for a short journey and return them at any other station in the city. A crucial factor for the success of such system is its ability to meet the fluctuating demand for bicycles and for vacant lockers at each station. In order to(More)
Peer review of research proposals and articles is an essential element in R&D processes worldwide. In most cases, each reviewer evaluates a small subset of the candidate proposals. The review board is then faced with the challenge of creating an overall " consensus " ranking on the basis of many partial rankings. In this paper we propose a branch-and-bound(More)
This research investigates the traffic police routine patrol vehicle (RPV) assignment problem on an interurban road network through a series of integer linear programs.
