Design and analysis of a continuous optoelectronic pulse wave velocity blood pressure sensor with multiple-subject controlled experiments
(Elsevier, 2022-10-16)
Goal: The main purpose of this study is to perform the pulse wave velocity (PWV) measurements with a new noninvasive optoelectronic continuous-time wearable sensor design and to analyze the quantitative relation between ...
A variable neighborhood search based matheuristic for a waste cooking oil collection network design problem
(Elsevier, 2022-10)
Households produce large amounts of waste cooking oil (WCO), which should be disposed properly to avoid its negative impacts on the environment. Using WCO as raw material in biodiesel production is an effective disposal ...
Branch-and-price approach for robust parallel machine scheduling with sequence-dependent setup times
(Elsevier, 2022-09-16)
This paper studies a machine scheduling problem that minimizes the worst-case total tardiness for unrelated parallel machines with sequence-dependent setup and uncertain processing times. We propose a robust optimization ...
Relief aid provision to en route refugees: Multi-period mobile facility location with mobile demand
(Elsevier, 2022-09-01)
Many humanitarian organizations aid en route refugee groups who are on their journey to cross borders using mobile facilities and need to decide the number and routes of the facilities. We define a multi-period facility ...
Hospital service levels during drug shortages: Stocking and transshipment policies for pharmaceutical inventory
(Springer, 2022-07)
In this study, we consider a health network that faces uncertain supply disruptions in the form of regional, nationwide, or worldwide drug shortages. Each hospital observes stochastic demand and if the drug is unavailable, ...
A data-driven matching algorithm for ride pooling problem
(Elsevier, 2022-04)
This paper proposes a data-driven matching algorithm for the problem of ride pooling, which is a transportation mode enabling people to share a vehicle for a trip. The problem is considered as a variant of matching problem, ...
Cost of fairness in agent scheduling for contact centers
(American Institute of Mathematical Sciences, 2022-03)
We study a workforce scheduling problem faced in contact centers with considerations on a fair distribution of shifts in compliance with agentpreferences. We develop a mathematical model that aims to minimize operatingcosts ...
Robust parameter design and optimization for quality engineering
(Springer, 2022-03)
This paper proposes a methodology to determine the optimal settings of key decision variables that affect the resilience of an engineering design against uncertainty. Uncertainty in quality engineering is often caused by ...
A fluid approximation for the single-leg fare allocation problem with nonhomogeneous poisson demand
(Springer, 2022-02-27)
Fare allocation for legs and O&D pairs plays a crucial role in airline revenue management. Despite a large number of dynamic pricing studies, there are only a few widely adopted studies in which assumptions affect most ...
Capacitated stochastic lot-sizing and production planning problem under demand uncertainty
(Elsevier, 2022)
This paper proposes two multi-period, multi-item capacitated stochastic lot-sizing problems under demand uncertainty. We model uncertainty via a scenario tree. The first model considers production, inventory, backlogging, ...
