Since its discovery in Houston, Texas, in 1987, the Asian "tiger mosquito" Aedes albopictus has spread to 678 counties in 25 states. This species, which readily colonizes container habitats in the peridomestic environment, was probably introduced into the continental United States in shipments of scrap tires from northern Asia. The early pattern of dispersal followed the interstate highway syst...

Galendromus occidentalis (Nesbitt) is one of several phytoseiid species that are available for purchase to supplement endemic predator populations that are not providing sufficient control of spider mites. We performed a series of releases of commercially reared G. occidentalis in commercial apple (Malus domestica Borkhausen) orchards in Washington from 2010 to 2012. Releases of up to 50,000 mi...

This paper develops an economic assessment of a multimodal transport network for single pallets. A shipment-size choice model is estimated to calculate the shippers’ reactions and their economic benefits from that transport network. In the model, the major factor influencing logistics decisions—the balance between warehouse and storage cost—is explicitly taken into account. The functional form ...

The bullwhip effect is a well-known phenomenon of demand information distortion in supply chains. To measure the bullwhip effect in a supply chain, researchers often resort to material flow data, i.e., shipments and sales data, as proxies for order and demand information. In this paper, we study the accuracy of such an approximated bullwhip measure and provide remedies for correcting the estima...

Aggregation problems arise when an expensive resource is shared by multiple agents. Shared access to this resource may result in agents incurring additional expenses, for example due to excessive wait time. This leads to a tradeoff between the frequency of access to the shared resource and the overhead costs for individual agents. Some participants of FCT may face this dilemma when heading to t...

Deciding shipment size is important in freight transport: it depends on the logistical imperatives of shippers and the technical possibilities of carriers. Shipment size choice is also closely related to transportation mode; it is therefore important from a public policy perspective. The theory of optimal shipment size and mode choice is robust. There are many inventory-theoretical models of op...
