Efficient Algorithms for Stochastic Ride-Pooling Assignment with Mixed Fleets

Transportation Science, 2023
Ride-pooling, which accommodates multiple passenger requests in a single trip, has the potential to substantially enhance the throughput of mobility-on-demand (MoD) systems. This paper investigates MoD systems that operate mixed fleets composed of “basic supply” and “augmented supply” vehicles.

A Lightweight Procedural Layer for Hybrid Experimental–Computational Workflows in Materials Science

Advanced Engineering Materials, EarlyView.
We unveil a prototype hybrid‐workflow framework that fuses automatedcomputation with hands‐on experiments. Built atop pyiron, a lightweight, parameterized layer translates procedure descriptions into executable manual steps, syncing instrument settings, human interventions, and data capture in real‐time today.

A duopoly competition problem of shared autonomous vehicles in a multimodal transportation system with government regulation

Multimodal Transportation
Shared autonomous vehicles (SAVs) are expected to revolutionize urban mobility. To explore the complex dynamics of competition and cooperation between operators and other traditional transportation modes, this study proposes a tri-level programming model

Stochastic Airline Fleet Assignment is PSPACE-complete

Electronic Notes in Discrete Mathematics, 2006
Abstract In recent years, optimization under the assumption that input data is not completely available at decision time has received an increasing attention. The reason is that our world seems to become increasingly dynamic, such that data from past have decreasing predictive power for planning and deciding.
