Abstract Automated long haul trucking is being developed for commercial deployment in the United States. One possible mode of this technology a “transfer-hub” model where operationally less complex highway driving automated, while human drivers drive more urban segment route. We study net impacts on tractor-trailer operator-hours from deployment. Using data 2017 Commodity Flow Survey, we gather...

We consider the problem of designating hazardous materials routes in and through a major population center. Initially, we restrict our attention to a minimally connected network (a tree) where we can predict accurately the flows on the network. We formulate the tree design problem as an integer programming problem with an objective of minimizing the total transport risk. Such design problems of...

Shipment consolidation is one of main initiatives to reduce CO2 emissions and transportation cost. It reduces the number shipments per customer costs by using larger shipments. This paper investigates temporal process in a central center make-to-order supply chain. research was motivated case study design furniture company that has many suppliers customers large parts Europe. Simulation used ch...

Many countries receive shipments of bulk cereals from primary producers. There is a volume of work that is on-going that seeks to arrive at appropriate standards for the quality of the shipments and the means to assess the shipments as they are out-loaded. Of concern are mycotoxin and heavy metal levels, pesticide and herbicide residue levels, and contamination by genetically modified organisms...

Detecting anomalies in the structural, or relational, component of data is a new and important challenge, especially in security-related domains. In this paper, we analyze the use of variations in graph properties to detect structural anomalies in graphs. Based on several pattern recognition approaches proposed on various domains like the internet, telecommunication call records and social netw...

We consider a multistage inventory system composed of a single warehouse that receives a single product from a single supplier and replenishes the inventory of n retailers through direct shipments. Ordering costs are dominated by the shipping costs associated with full truckload transportation with cargo capacity constraints. All costs are stationary. Demands for the n retailers over a planning...
