Real-Time Stochastic Matching Models for Freight Electronic Marketplace
Avinash Unnikrishnan
This grant from the National Science Foundation (NSF) will support research investigating how a real-time marketplace might be constructed to match freight shipments with available carriers. In such a system, freight shippers make a request to the system manager, and an automated service will match shipping jobs to carriers who are likely to accept them. The benefits of such a system include more efficient use of freight capacity (fewer empty miles) and reduced shipping prices, resulting in e...
