Understanding drug transportation mechanisms in the human body is of paramount importance in modeling Pharmacokinetic-Pharmacodynamic relationships. This work gives a novel general model of efavirenz transportation projections based on concentrations simulated from patients on a dose of 600 mg. The work puts forward a proposition that transportation can wholly be modeled by concentration and ti...

This Chapter focuses on Intermodal Freight Transportation, broadly defined as the transportation of a load from its origin to its destination by a sequence of at least two transportation modes, the transfer from one mode to the next being performed at an intermodal terminal. Container-based transportation services are an important part of intermodal transportation and the backbone of internatio...

When a make-to-order manufacturing company adopts a commit-to-delivery business mode, it commits a delivery due date for an order and is responsible for the shipping cost. Without loss of generality, we consider that transportation is done by a third party logistics company such as FedEx or UPS, which provides multiple shipping modes such as overnight, one-day, two-day delivery, and more. When ...

Please cite this article in press as: Wolfson, O., Res. Part C (2012), doi:10.1016/j.trc.2012.02.0 Intelligent Transportation Systems envision a networked environment consisting of vehicles, the infrastructure, and hand-held devices (e.g., smart-phones). The environment will enable numerous safety, mobility, and environmental improvement applications. For example, drivers can be warned of dange...

This chapter is an introduction to the economics of the connection between urban transportation and land use. The nature of the transportation system strongly influences the patterns of land use in an urban area. Indeed, the long-run histories of urban areas sometimes are identified with the dominant mode of transportation of the time; the age of rail, the age of the automobile, and so on. Supp...

It is necessary to consider the impact of demand uncertainty to model the comprehensive approach for supply chain network design. This paper presents four echelons, multiple commodity, and strategic–tactical model for designing supply chain network. Uncertain demand, transportation mode selection with lead time configuration has been considered. A numerical example has been implemented to verif...

Many school districts in the United States allow parents to choose which school their child attends (`school choice' or `magnet schools') while other school districts require students to attend their nearest (`neighborhood') school. Such policies influence children's transportation. We survey elementary-school parents in St. Paul and Roseville, Minnesota, to discover how children travel to scho...

Travel Mode Identification with Smartphone Sensors by Xing Su Advisor: Hanghang Tong Personal trips in a modern urban society typically involve multiple travel modes. Recognizing a traveller’s transportation mode is not only critical to personal context-awareness in related applications, but also essential to urban traffic operations, transportation planning, and facility design. While the stat...

The purpose of multi-modal route planning is to provide the traveler with optimal, feasible and personalized route between origin and destination, which may involve public and private transportation modes. The strategy driven approach (i.e. routing by certain predefined transfer order) is useful but can hardly provide free combination of multiple travel modes and some feasible results may be co...

Most distribution network design models considered to date have focused on minimizing fixed costs of facility location and transportation costs. Measures of customer satisfaction driven by the operational dynamics such as lead times have seldom been considered. We consider the design of an outbound supply chain network considering lead times, location of distribution facilities and choice of tr...
