The role of detailed simulation in capacity planning

In summary, FIVE provides sufficient detail to permit capacityplanning decisions to be made quickly and accurately, and without disrupting an ongoing operation. New applications can be accommodated, volume growth of existing applications can be planned for, and the effects of system changes can be assessed. The latter include such diverse elements as conversion from BSC to SDLC, screen and controller configuration on a line, installation of faster line scanners in the TCU, changing the printer mode from data stream compatibility to SNA character string, and conversion of disk I/O to fixed-block architecture.
