John Dutton Conant Little (February 1, 1928)[1] is an Institute Professor at the Massachusetts Institute of Technology.[2]
Born in Boston, he earned a S.B. in physics from Massachusetts Institute of Technology (1948) and worked at General Electric (1948–50). His Ph.D. on Use of Storage Water in a Hydroelectric System used dynamic programming, and advised by Philip M. Morse, was the first ever awarded in operations research (1955).[3] Next, he taught at Case Western Reserve (1957–62) before joining the faculty at MIT (1962) where he since has worked. He was visiting professor at INSEAD (1988)
His earlier research in Operations Research involved traffic signal control, and gave him fame as he formed the Little's law in 1961. It 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." Little is considered to be a founder of marketing science,[4] having conducted fundamental research in models of individual choice behavior, adaptive control of promotional spending, and marketing mix models for consumer packaged goods. He has also started companies such as Management Decisions Systems and Kana Software. The John D. C. Little Award is awarded annually by INFORMS.[5] He is the father of John N. Little[6].
