A New Formulation for the Dial-a-Ride Problem

Transportation Science, 2021
This paper proposes a new mixed integer programming formulation and branch and cut (BC) algorithm to solve the dial-a-ride problem (DARP). The DARP is a route-planning problem where several vehicles must serve a set of customers, each of which has a pickup and delivery location, and includes time window and ride time constraints.

A Matheuristic for the Dial-a-Ride Problem

2011
The Dial-a-Ride is a transport system on demand. A fleet of vehicles, without fixed routes and schedules, carries people from their pickup points to their delivery points, during a pre-specified time interval. It can be modeled as an N P-hard routing and scheduling problem, with a suitable mixed integer programming formulation. Exact approaches to this
