Knowledge Gradient Procedure to Select the Best System Under Pairwise Comparisons

open access: yesNaval Research Logistics (NRL), EarlyView.
ABSTRACT This article considers fixed‐budget ranking and selection (R&S) problems where the performance of alternative designs can only be assessed through pairwise comparisons, a setting encountered in many applications, including player ranking in games, sports tournaments, recommender systems, image‐based search, public choice models such as voting ...

New Policies Exploiting Randomness of Lead Times in Inventory Systems

open access: yesNaval Research Logistics (NRL), EarlyView.
ABSTRACT Recent research provided proof‐of‐concept that the randomness of lead times in inventory systems can be exploited to achieve large—potentially unlimited—performance improvements, compared to the case of constant lead time. Specifically, the Generalized Base Stock (GBS) policy serves as such proof‐of‐concept—it can deliver unlimited ...

A Cost Function Approximation Based Large Neighborhood Search for Dynamic Medical Courier Services

open access: yesNetworks, EarlyView.
ABSTRACT Medical on‐demand couriers play an important role in urban medical services. They transport medical supplies, tests, blood, or organs between different locations in the city within a short amount of time. Transportation orders are issued spontaneously and differ in their priority and time restrictions. Since all orders must be served, the goal

Mixed‐Integer Linear Programming Approaches for Nested p$$ p $$‐Center Problems With Absolute and Relative Regret Objectives

open access: yesNetworks, EarlyView.
ABSTRACT We introduce the nested p$$ p $$‐center problem, a multi‐period variant of the well‐known p$$ p $$‐center problem. Using the nesting concept allows us to obtain solutions consistent over the considered time horizon, that is, facilities that are opened in a given time period stay open for subsequent periods.

Will biodiversity actions yield healthy places? A systematic review of human health outcomes associated with biodiversity‐focused urban greening

open access: yesPeople and Nature, EarlyView.
Abstract There is growing interest in using urban greening projects to support biodiversity. While there are many potential co‐benefits, the health outcomes resulting from biodiversity‐supporting activities have yet to be synthesized. We conducted a systematic review of health outcomes associated with seven biodiversity‐supporting elements, including ...
