A Robust Optimization Approach to Public Transit Mobile Real-time Information

Real-Time Optimization Approach for Mobile Robot

Robust Real-time Information Infrastructures

Reliable and secure communication is at the heart of well being and delivery of critical services in today’s society, making power grids, financial services, transportation, government and defence highly dependent on ICT networks. Regional and national emergencies are characterised by their devastating effect on human lives and the society’s ability to function. Unfortunately, rescue operations...

Mobile Transit Trip Planning with Real–Time Data

In this article, we describe the development of a transit trip planner (TTP) for mobile devices called Transitr, and evaluate its performance. The system predicts the shortest paths between any two points in the transit network using real-time information provided by a third party bus arrival prediction system, relying on GPS equipped transit vehicles. Users submit their origin and destination ...

a robust optimization approach to resources allocation in maintained systems

optimization of maintenance resources to maximize the system availability is a major concern in different manufacturing systems. therefore, a lot of effort is put to construct optimization models to reach the maximum availability level and to reduce the costs of lack of availability. however, despite these efforts, data uncertainty in the real world problems was neglected in proposed models whi...

Real - Time Optimization Model for Dynamic Scheduling of Transit Operations

A new transit operating strategy is presented in which service vehicles operate in pairs with the lead vehicle providing an all-stop local service and the following vehicle being allowed to skip some stops as an express service. The underlying scheduling problem is formulated as a nonlinear integer programming problem with the objective of minimizing the total costs for both operators and passe...
