Computer Selection
| Hi-index | 0.00 |
Decisions about selecting a configuration for a computer system require an unbiased comparison among alternative designs of the system. Several heterogeneous factors need to be considered and their combined effect must be evaluated. The procedure provides a structure to the selection process activities: developing a selection plan, evaluating each design, and ranking the alternatives. It is based on a cost-effectiveness methodology which characterizes each design by the life-cycle cost through a "system cost index" and by the design effectiveness in reaching the system objectives through a "system utility index." The procedure is applicable to the selection of a system, to tradeoff analysis during the system design, and may constitute the framework for the analysis of the risk associated to a design implementation.
