A fast metaheuristic approach for the planar multiple obnoxious facility location problem

International Transactions in Operational Research, EarlyView.
Abstract The multiple obnoxious facility location problem is one of the most studied problems in the literature of the obnoxious facility location problems family. In this work, we propose an alternative algorithmic approach for this problem, based on an efficient metaheuristic procedure over a discretization of the plane based on Voronoi diagrams ...

An effective and efficient matheuristic for the electric vehicle routing problem with capacitated recharging stations

International Transactions in Operational Research, EarlyView.
Abstract In this paper, we address the problem of routing a fleet of electric vehicles (EVs) to serve a set of customers, geographically distributed, within their time windows. We assume that EVs may also be recharged en route, and the amount of energy recharged at a recharging station (RS) is a decision variable itself, that is, partial recharges are ...

A matheuristic for the traveling salesman problem with positional consistency constraints

International Transactions in Operational Research, EarlyView.
Abstract We propose a matheuristic for the traveling salesman problem with positional consistency constraints, where we seek to generate a set of routes with minimum total cost, in which the nodes visited in more than one route (consistent nodes) must occupy the same relative position in all routes.

A formulation and a metaheuristic approach for the clustered vehicle routing problem with d‐relaxed priority rule

International Transactions in Operational Research, EarlyView.
Abstract This paper investigates an extension of the vehicle routing problem in which, in addition to minimizing the distance traveled, the sequencing of customer visits is subject to precedence constraints that impose visiting priorities among customers.

Freight distribution optimization by implementing the team orienteering problem with occasional drivers

International Transactions in Operational Research, EarlyView.
Abstract This research evaluates the effectiveness of a hybrid crowdshipping system that integrates occasional drivers with traditional delivery services (OD+TD) to improve the efficiency of freight distribution. By implementing the team orienteering problem with occasional drivers model, we develop a mathematical model and an agile optimization ...

The Experiences of People From Ethnic Minority Backgrounds Living in Care Homes—A Qualitative Systematic Review

Journal of Advanced Nursing, EarlyView.
ABSTRACT The experiences of people from ethnic minority backgrounds living in care homes—A qualitative systematic review. Aim Despite the increasing need for older people from ethnic minority backgrounds to be able to access good quality, culturally competent care home provision, globally, there is an absence of literature exploring care home residents'

Cultural Beliefs and Practices of Internationally Educated Nurses in the Context of Cancer and End‐Of‐Life Care: A Hermeneutic Inquiry

Journal of Advanced Nursing, EarlyView.
ABSTRACT Aims This study aimed to (1) gain an understanding of the experiences of IENs in providing cancer and end‐of‐life care; (2) explore their cultural beliefs and practices and analyse how their experiences, beliefs, and practices shape approaches to nursing care within this care context. Design Hermeneutic inquiry.
