Enhancing pharmaceutical cold supply chain: integrating medication synchronization and diverse delivery modes

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract The significance of last‐mile logistics in the healthcare supply chain is growing steadily, especially in pharmacies where the growing prevalence of medication delivery to patients' homes is remarkable. This paper proposes a novel mathematical model for the last‐mile logistics of the pharmaceutical supply chain and optimizes a pharmacy's ...

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

open access: yesInternational 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 ...

Vessel arrival planning with full information

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract Planning efficiency and timely arrival of vessels is crucial to smooth operations of maritime transport networks, ensuring optimal utilization of resources and minimizing operational costs. Coordination between vessel operators and terminals has the potential to reduce costs, fuel consumption, and waiting time.

Geometric Distributions in the Theory of Queues

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 1959
SUMMARY First a new explanation in probability terms is given for the occurrence of geometric or conditional geometric distributions in some queueing problems. The methods used allow some simple but useful generalizations to be obtained.

Retrial queuing system MMPP|GI|1 researching by means of the second-order asymptotic analysis method under a heavy load condition

open access: yesИзвестия Томского политехнического университета: Инжиниринг георесурсов, 2019
Retrial queuing systems which are mathematical models of real processes in telecommunication systems are a new developing direction of the queuing theory. However the analytical formulas are obtained only for systems with Poisson arrival process. Most of
