Information Systems in Management Science

The number of on-line computer applications that exist today gives ample testimony that the computer hardware business has come of age. About fifteen years ago, IBM built the SAGE system which, for the first time, tied computers together with a number of other components. A large central processor communicated with a number of peripheral processors that controlled radar units. Every component had to be specially designed and built at no small cost. Today, the components of a similar system would be standard, with a computer, the interfaces, and the teleprocessing all catalog items.
