The optimality of an (s, S) hiring policy on a workforce planning problem with fixed recruitment costs and binomial turnover
Zhen Chen, Roberto Rossi, Belen Martin-Barragan +1
We study a finite-horizon nonstationary workforce planning problem in which staff turnover in each period follows a binomial distribution whose parameters depend on the post-hiring…
Smart predict-then-robustly-optimize
Aakil Caunhye, Xuefei Lu, Belen Martin-Barragan
In this paper, we propose and study a robust variant of the smart predict-then-optimize approach that accounts for prediction shifts due to disturbance in the covariate feature spa…
Controlling inventory on electric roads
Alejandro Gutierrez-Alcoba, Roberto Rossi, Belen Martin-Barragan +1
Electric road systems (ERS) are roads that allow compatible vehicles to be powered by grid electricity while in transit, reducing the need for stopping to recharge electric batteri…
Modelling antimicrobial prescriptions in Scotland: A spatio-temporal clustering approach
Antonia Gieschen, Jake Ansell, Raffaella Calabrese +1
In 2016 the British government acknowledged the importance of reducing antimicrobial prescriptions in order to avoid the long-term harmful effects of over-prescription. Prescriptio…
An (R, S) Based Heuristic Model for the Stochastic Joint Replenishment Problem
Mengyuan Xiang, Roberto Rossi, S. Armagan Tarim
This paper considers the periodic-review stochastic joint replenishment problem (JRP) under Bookbinder and Tan's static-dynamic uncertainty control policy. According to a static-dy…
A mathematical programming-based solution method for the nonstationary inventory problem under correlated demand
Mengyuan Xiang, Roberto Rossi, Belen Martin-Barragan +1
This paper extends the single-item single-stocking location non-stationary stochastic inventory problem to relax the assumption of independent demand. We present a mathematical pro…
The Dynamic Bowser Routing Problem
Roberto Rossi, Maurizio Tomasella, Belen Martin-Barragan +3
We investigate opportunities offered by telematics and analytics to enable better informed, and more integrated, collaborative management decisions on construction sites. We focus…
Computing non-stationary policies using mixed integer linear programming
Mengyuan Xiang, Roberto Rossi, Belen Martin-Barragan +1
This paper addresses the single-item single-stocking location stochastic lot sizing problem under the policy. We first present a mixed integer non-linear programming (MIN…
