Integrated location–inventory planning for slow‐moving demands with waiting time limitations
International Transactions in Operational Research, EarlyView.Abstract This paper studies a stochastic facility location problem integrated with inventory and transportation decisions (SFLPIT) for supply chains with slow‐moving stock‐keeping units (SKUs). Local stores often avoid maintaining such SKUs, resulting in customer demand being fulfilled directly by a central distribution center (DC), where the ...

Can the localization ratio be considered as a resilience indicator in the supply chain?
International Transactions in Operational Research, EarlyView.Abstract Supply chain resilience is concerned with establishing disruption‐resistant operational practices and ensuring the achievement of some planned performance responding to shocks. Thus, resilience is both a quality and a quantity. The existing literature is rich in analyzing each of these two parts separately. However, studies connecting quantity

A unified formulation for home healthcare routing and scheduling problems
International Transactions in Operational Research, EarlyView.Abstract Home Healthcare is an essential component of healthcare systems, where caregivers visit patients' homes to deliver services. While presenting advantages with respect to institutional care, such as being cost‐effective and alleviating family burdens, it presents challenges in scheduling and routing caregivers efficiently.

The impact of public drop‐off boxes and autonomous delivery robots in last‐mile delivery
International Transactions in Operational Research, EarlyView.Abstract The growing concern over emissions from last‐mile logistics is motivating the development of innovative delivery models aimed at reducing environmental impact and traffic congestion. To this end, we propose a last‐mile delivery scheme based on both public drop‐off boxes and autonomous delivery robots.

Enfoque estocástico de la incertidumbre en la selección de carteras de proyectos
Rect@, 2013 In this paper we develop a 0-1 integer multiobjective programming. model to simultaneously select and plan a portfolio of projects from a set of initial proposals. Projects in the portfolio are allowed to start at different moments of time , according to

International Transactions in Operational Research, EarlyView.Abstract We address the scheduling conflicting jobs on parallel identical machines problem with makespan minimization, a classical and computationally challenging variant of parallel machine scheduling. We develop and evaluate three distinct solution methodologies: a novel constraint programming (CP) formulation, and two metaheuristics: a multi ...

Journal of Fish Biology, EarlyView.Abstract Understanding the factors that shape population genetic structure is crucial for advancing evolutionary studies and developing effective management and conservation strategies. The northern pike (Esox lucius L.) is a top teleost predator that inhabits fresh and brackish water environments in the northern hemisphere.

Best Before? Expiring Central Bank Digital Currency and Loss Recovery
Journal of Money, Credit and Banking, EarlyView.Abstract Physical cash enables payments in the absence of electricity or network coverage. Such offline payment functionality promotes the operational resilience and, particularly in developing countries, the accessibility of payments. Central banks are exploring issuing digital cash substitutes with similar offline payment functionality.

Stochastic programming with integer recourse
, 1995 In this thesis we consider two-stage stochastic linear programming models with integer recourse. Such models are at the intersection of two different branches of mathematical programming. On the one hand some of the model parameters are random, which places the problem in the field of stochastic programming.
