Imagine that on a much bigger scale, like the nearly $54 billion in perishable retail food lost in the U.S. in 2011. That problem helped compel operations management researchers Opher Baron and Oded Berman at the University of Toronto's Rotman School of Management and their colleagues Hossein Abouee-Mehrizi of the University of Waterloo and David Chen of the Chinese University of Hong Kong, Shenzhen to devise a method for a timelier and less costly distribution of perishable inventory under simultaneous, multiple types of demands.

"There are hungry people in the world," said Prof. Baron who is a Distinguished Professor of Operations Management at the Rotman School. "To me, this waste of resources is a critical issue that makes it interesting to find out how we can better control these perishable inventories."
