A modeling system for simulation of dial-a-ride services [PDF]
, 2012 We present a modeling system for simulation of dial-a-ride services. It can be used as a tool for understanding and study how different designs, and different ways to operate a dial-a-ride service, affect the performance and efficiency of the service ...

Out of Sync? Rare Genetic Disease and the Chronopolitics of Care
Sociology of Health &Illness, Volume 47, Issue 8, November 2025.ABSTRACT Drawing on the experiences of parents of children diagnosed with Noonan Syndrome, I examine how living in and between multiple temporalities of care impacts parents’ sense of temporal autonomy and social inclusion. Employing the concept of ‘crip time’, I connect everyday choreographies of care with their temporal politics to analyse the ...

The electric autonomous dial-a-ride problem
, 2020 This thesis develops mathematical programming frameworks to operate electric autonomous vehicles in the context of ride-sharing services. The introduced problem is a novel variant of the Dial-a-Ride Problem (DARP), denoted by the electric Autonomous Dial-a-Ride Problem (e-ADARP), and includes battery management and autonomous aspects along with classic
