Intermodal transit system coordination with dynamic vehicle dispatching
… to complete their journey. Therefore, scheduling vehicles operating in the system with special attention to reduce transfer time can contribute significantly service quality improvements. In this study two models, one for coordination of a general intermodal. transit system and another for dynamic …

Joint Vehicle Dispatching and Redeployment for Emergency Medical Services with Multi-Critic Reinforcement Learning
… of achieving this efficiency lies in how the EMS vehicles are dispatched to a patient from the currently available fleet and how they are then redistributed to best cover the area of care. This problem can be formulated as both a Markov-Decision Process and as a Multi-Agent Markov Game in which we …

The impact of vehicle dispatching on the design of multiple-transporters material handling systems
Although Automated Guided Vehicle Systems (AGVS) have been around for more than thirty years, designing an AGVS is still a difficult process because of the interaction of numerous system decisions. The many important elements and variables that must be considered when designing AGVS include the …

Optimizing Urban Air Mobility Operations in a Corridor Network
Electric vertical-takeoff-and-landing vehicles give rise to Urban Air Mobility (UAM) concepts. Initial UAM systems are projected to operate high volumes of flights within a capacitated corridor network. This paper develops a tractable methodology to optimize vehicle dispatching and routing in UAM …

Non-branching hybrid transit network design under heterogeneous demand
… (2014). To obtain optimal network layout and vehicle dispatching frequencies, a mathematical model that minimizes transit system cost based on various zone-to-zone demands is formulated. By allowing different stop spacing in the central and peripheral regions, more flexibility is given to the …

A design methodology for operational control elements for automatic guided vehicle based material handling systems
… control aspects of an Automatic Guided Vehicle (AGV) based material handling system is presented. The methodology, which is composed of an integrated model of an AGV based system, was implemented using simulation techniques. The model views a manufacturing function as consisting of …

Design and operation of a last mile transportation system
… Routes and schedules are determined for a multi-vehicle fleet of delivery vehicles with the objective of minimizing the waiting time and riding time of passengers. A myopic operating strategy is introduced first. Two more advanced operating strategies are then described, one based on a …

Resource allocation and pricing under competition in shared mobility markets
… those related to owning and maintaining a vehicle; (iii) increased accessibility of users, e.g., by bridging the spatiotemporal gaps in existing transportation service networks (Shaheen et al., 2016); and (iv) creation of new job opportunities; for example, in 2014, the Uber platform …
