A genetic algorithm simheuristic for solving the stochastic project portfolio selection problem with portfolio reliability constraints

open access: yesInternational Transactions in Operational Research, Volume 33, Issue 6, Page 4039-4071, November 2026.
Abstract In response to the increasing complexity of modern products, dynamic markets, and intensified competition, project‐based organizations are actively seeking methodologies to efficiently manage their expanding project portfolios. This paper analyzes the project portfolio selection problem in uncertain environments. Despite recent advances in the

Can the localization ratio be considered as a resilience indicator in the supply chain?

open access: yesInternational Transactions in Operational Research, Volume 33, Issue 6, Page 3698-3713, November 2026.
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

The impact of public drop‐off boxes and autonomous delivery robots in last‐mile delivery

open access: yesInternational Transactions in Operational Research, Volume 33, Issue 6, Page 3825-3854, November 2026.
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.

Testing for Genetic Interactions in Complex Disease With Distance Correlation

open access: yesBiometrical Journal, Volume 68, Issue 5, October 2026.
ABSTRACT Understanding epistasis (genetic interaction) may shed some light on the genomic basis of common diseases, including disorders of maximum interest due to their high socioeconomic burden, like schizophrenia. Distance correlation is an association measure that characterizes general statistical independence between random variables, not only the ...

A Chance‐Constrained Model for a Production Routing Problem With Uncertain Availability of Vehicles

open access: yesNetworks, Volume 88, Issue 3, Page 295-312, October 2026.
ABSTRACT The Production Routing Problem (PRP) is a complex integrated problem that allows for the achievement of competitive advantages, such as better management of inventory, reduction in operational costs and lead times, improvement in efficiency and customer service, and better response to market changes.
