John Little

John D.C. Little. (Institute Professor and Chair Management Science for MIT's Sloan School of Management)

Little's law states: "The average number of customers in a system (over some interval) is equal to their average arrival rate, multiplied by their average time in the system." A corollary has been added: "The average time in the system is equal to the average time in queue plus the average time it takes to receive service."

He is considered to be a founder of marketing science.
