Nagurney Publishes Article in Transportation Research Part E

Ladimer S. Nagurney, associate professor of electrical, computer, and biomedical engineering, CETA, has had the article, "Dynamics and Equilibria of Ecological Predator-Prey Networks as Nature’s Supply Chains," accepted for publication in the journal Transportation Research Part E: Logistics and Transportation Review.

The article is co-authored with Anna Nagurney, the John F. Smith Memorial Professor of Operations Management at the Isenberg School of Management at the University of Massachusetts Amherst. It develops a dynamic network model of ecological food webs and establishes the equivalence between the ecological models and supply chain network equilibrium models that have been developed for industrial applications.

The article also highlights the connections to spatial price economic equilibrium problems. Finally, the paper proposes an algorithmic scheme, provides convergence results, and applies the scheme to a food web drawn from a real world complex predator-prey application.

Transportation Research Part E publishes informative articles drawn from across the spectrum of logistics and transportation research, including logistics and supply-chain management. It is ranked as the No. 3 journal in transportation.
