Abstract : A review is made of some existing time-sharing computer systems and an exploration of various software characteristics is conducted. This investigation is conducted using a computer program with which a typical time-sharing system can be simulated. The basic system parameters examined are: (1) the method of determining the quantum time for each user per response cycle, (2) the length of the desired response cycle, (3) the number of remote stations permitted and (4) the maximum number of users permitted in the queue at one time. The results of these simulation runs are presented. The effects of the various parameters upon the average response cycle time, the average number in the queue awaiting service, the average length of time a user is in the queue and the computational efficiency plus other characteristics of the system are discussed.
