Meeting Uncertain Threats with Feedback
Louis L Chen, Ang Xu, Roberto Szechtman +2
Air and missile defense, naval force protection, and critical-infrastructure security require rapid allocation of scarce effectors against multiple incoming threats when neutraliza…
A Markovian Traffic Equilibrium Model for Ride-Hailing
Song Gao, Hanyu Cheng, Chiwei Yan +1
We develop a Markovian traffic equilibrium model for ride-hailing in which vehicles, whether empty or hired, make sequential order-acceptance and link-choice decisions over a traff…
On-Trip Matching and Pricing for Shared Rides
Yifan Shen, Junlin Chen, Julia Yan +1
Although shared rides have the potential to increase vehicle utilization and reduce congestion and emissions, these benefits depend heavily on ridesharing platforms' ability to mat…
Dispatching and Pricing in Two-Sided Spatial Queues
Ang Xu, Chiwei Yan
We study a dispatching and pricing problem in two-sided spatial queues with fixed supply, motivated by ride-hailing and robotaxi platforms. Idle drivers queue on one side, waiting…
On the Linear Programming Model for Dynamic Stochastic Matching and Its Application to Pricing
Junlin Chen, Chiwei Yan, Hai Jiang
Important pricing problems in centralized matching markets -- such as carpooling, food delivery and freight shipping platforms -- often exhibit a bi-level structure. At the upper l…
