Determinant Study of Conventional Transportation and Online Transportation

Electrified Transportation System Performance: Conventional vs. Online Electric Vehicles

In recent years, the electrification of ground transportation has emerged as a trend to support energy efficiency and CO2 emissions reduction targets. The true success, however, of this trend depends on the successful integration of electric vehicles into the infrastructure systems that support them. Left unmanaged, conventional electric vehicles may suffer from delays due to charging or cause ...

The Online Transportation Problem

We study the online transportation problem. We show that the halfopt-competitive ratio for the greedy algorithm is (min(m; logC)), where m is the number of server sites, and C is the total number of servers. We also present an algorithm Balance that is a modi cation of the greedy algorithm and that has a halfopt-competitive ratio of O(1).

Fuzzy Transportation Problem with Random Transportation Costs

We consider the following transportation problem with both random and fuzzy factors. There exist m supply points and n demand points. For each route between supply point and demand point, unit transportation cost is a random variable according to a normal distribution and existence possibility denoting the preference choosing this route is attached. The probability that the total transportation...

A Study of Transportation Disruption Causes and Costs in Containerized Maritime Transportation

This research focuses on estimating and understanding the costs and causes of transportation related supply chain disruptions. In-depth interviews with logistics managers were undertaken to investigate how companies perceive transportation related supply chain disruptions and what they are doing to respond and address them. Stated choice experiments were designed to estimate the cost of disrupt...
