Sustainable Development, EarlyView.ABSTRACT The dynamic nature of small islands being geographically isolated and their perceived connectedness with global networks complicates research attempts to draw general conclusions on whether insularity leads to marginalization or strengthens their resilience for sustainable development.

Restless bandit marginal productivity indices I: singleproject case and optimal control of a make-to-stock M/G/1 queue [PDF]
, 2004 This paper develops a framework based on convex optimization and economic ideas to formulate and solve by an index policy the problem of optimal dynamic effort allocation to a generic discrete-state restless bandit (i.e. binary-action: work/rest) project,

The single server retrial queue with finite population: a BSDE approach
, 2012 This paper uses the block-structured state-dependent event (BSDE) approach to generalize the scalar version of the single server retrial queue with finite population.

The single server semi-markov queue [PDF]
, 1986 A general model for the single server semi-Markov queue is studied. Its solution is reduced to a matrix factorization problem. Given this factorization, results are obtained for the distributions of actual and virtual waiting times, queue lengths both at

Sustainable Development, EarlyView.ABSTRACT This article examines whether economic growth reduces inequalities in access to water and sanitation across 64 countries over an average period of 13.5 years. Drawing on disaggregated data by income quintiles and rural–urban location, and employing ordinary least squares (OLS), two‐stage least squares (2SLS), and Seemingly Unrelated Regression

Velocity‐based stowage policy for a semiautomated fulfillment system
Production and Operations Management, EarlyView., 2022 Abstract Online retail fulfillment is increasingly performed by semiautomated fulfillment systems in which inventory is stored in mobile pods that are moved by robotic drives. In this paper, we develop a model that explores the benefits of velocity‐based stowage policies for semiautomated fulfillment systems, also known as robotic mobile fulfillment ...

The influence of demand variability on the performance of a make-to-stock queue [PDF]
Variability, in general, has a deteriorating effect on the performance of stochastic inventory systems. In particular, previous results indicate that demand variability causes a performance degradation in terms of inventory related costs when production ...

Data Schema Evolution for the Self‐Adaptive Software Domain: A Systematic Mapping Study
Software: Practice and Experience, EarlyView.ABSTRACT Context Self‐adaptive Software (SaS) is a special category of software systems that enables adaptation at runtime to address new user requirements or changes in its execution environment. This article focuses on a specific category of SaS named SaS2DB, which encompasses systems that require the storage of data in a database. In short, a SaS2DB
