The use of Floating Car Data (FCD) as a particular case of Probe Vehicle Data (PVD) has been the object of extensive research for estimating traffic conditions, travel times and Origin to Destination trip matrices. It is based on data collected from a GPS-equipped vehicle fleet or available cell phones. Cooperative Cars with vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communica...
A mathematical model for dynamic fleet planning with multi routes and multi ship, which took the maximum total operation profits as its objective function, was built up according to the characteristics of the shipping company. The model had the following characteristics: Firstly in the model, the long-term fleet planning and short-term scheduling were combined. Secondly, the economic and techno...
This paper introduces Global Fleet Station Mission Planner (GFSMP), an optimization tool to aid in mission planning and the scheduling of humanitarian assistance missions for the US Navy. GFSMP helps fleet staffs to examine how one naval ship, which was deployed for an extended period (e.g., six months), with embarked teams can best provide humanitarian assistance. We illustrate the application...
It is common for professional associations and regulators to combine the claims experience of several insurers into a database known as an “intercompany” experience data set. In this paper, we analyze data on claim counts provided by the General Insurance Association of Singapore, an organization consisting of most of the general insurers in Singapore. Our data comes from the financial records ...
Fleet management systems are commonly used to coordinate mobility and delivery services in a broad variety of domains. However, their traditional top-down control architecture becomes a bottleneck in open and dynamic environments, where scalability, proactiveness, and autonomy are becoming key factors for their success. Here, the authors present an abstract event-based architecture for fleet ma...
Transport related emissions have been long associated with adverse impacts on air quality particularly in densely populated urban areas. This paper evaluates the contribution of the road transport sector, in a typical small developing country, to air pollutants emissions. The Motor Vehicle Emission Inventory (MVEI) computer based model, with inputs adjusted to the fleet and conditions at hand, ...
This paper incorporates owners' decisions to keep, repair or scrap their old vehicles into a simulation model of fleet emissions. This decision depends critically on the owner's perceived value of the vehicle, so we examine the factors affecting owners' valuations of their old vehicles using a unique longitudinal dataset. Willingness to accept for the vehicle is well predicted by mileage and co...
The VIPAFLEET project consists in developing models and algorithms for managing a fleet of Individual Public Autonomous Vehicles (VIPA). Hereby, we consider a fleet of cars distributed at specified stations in an industrial area to supply internal transportation, where the cars can be used in different modes of circulation (tram mode, elevator mode, taxi mode). One goal is to develop and implem...
This paper shows how to coordinate the pricing and fleet management decisions of a freight carrier. We consider a setting where the carrier announces its prices at the beginning of a certain time horizon and the load arrivals over this horizon depend on the announced prices. Assuming that the vehicle fleet is managed according to a particular class of fleet management models, we present a tract...
Integrated Competitive Pricing and Transshipment Problem for Short Life Cycle Products’ Supply Chain
This paper integrates competitive pricing and network design problems for the short life cycle products. The pricing problem determines selling prices of the products for different life cycle phases in a competitive market, as well as acquisition management of returned products. Besides, the selling and acquisition prices are related to the distance between distribution centers and customers. T...
