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."
