This paper solves a particular class of Real Time Vehicle Dispatching Problems where there is need to service some customers with multiple resources subject to synchronization constraints. Real world applications are presented and a flexible heuristic based on Constraint Programming is proposed. In order to facilitate future comparisons, benchmark instances are derived from well-known vehicle r...

This paper considers the Dynamic Multi-Period Vehicle Routing Problem which deals with the distribution of orders from a depot to a set of customers over a multi-period time horizon. Customer orders and their feasible service periods are dynamically revealed over time. The objectives are to minimize total travel costs and customer waiting, and to balance the daily workload over the planning hor...

This paper presents the difference in behavior between hollow-core fiber reinforced polymer-concrete-steel (HC-FCS) columns and conventional reinforced concrete (RC) columns under vehicle collision in terms of dynamic and static forces. The HC-FCS column consisted of an outer FRP tube, an inner steel tube, and a concrete shell sandwiched between the two tubes. The steel tube was hollow inside a...

Over the past few years, ride-sharing has emerged as an e ective way to relieve tra c congestion. A key problem for these platforms is to come up with a revenue-optimal (or GMV-optimal) pricing scheme and an induced vehicle dispatching policy that incorporate geographic and temporal information. In this paper, we aim to tackle this problem via an economic approach. Modeled naively, the underlyi...

This paper briefly describes a system that captures the accelerations of a vehicle, and displays this information haptically to a remote user controlling that vehicle. The motivations for this system are that the haptic cues relating to the vehicle’s experiences have the potential to provide the user with improved control over the vehicle, to more firmly place the user within the environment th...

Recent years have witnessed great advancements in the sciences and technology of autonomy, robotics and networking. This dissertation develops concepts and algorithms for dynamic vehicle routing (DVR), that is, for the automatic planning of optimal multi-vehicle routes to provide service to demands (or more generally to perform tasks) that are generated over time by an exogenous process. We con...

To the chagrin of well intentioned Army leaders, dozens of soldiers are killed each year as a result of combat vehicle accidents. The objective of this study is to look beyond the events and symptoms of accidents which normally indicate human error, and instead study the upper-level organizational processes and problems that constitute the actual root causes of accidents. After a short review o...

The principal focus of this paper is to study carrier pricing decisions for a type of vehicle routing problems defined in a competitive and dynamic environment. This paper introduces the Vehicle Routing Problem in a Competitive Environment (VRPCE), as an extension of the Traveling Salesman Problem with Profits (TSPP) to a dynamic competitive auction environment. In the VRPCE, the carrier must e...

In this study, the roll, yaw and depth fuzzy control of an Au- tonomous Underwater Vehicle (AUV) are addressed. Yaw and roll angles are regulated only using their errors and rates, but due to the complexity of depth dynamic channel, additional pitch rate quantity is used to improve the depth loop performance. The discussed AUV has four aps at the rear of the vehicle as actuators. Two rule bases...
