The economic evaluation of information storage and retrieval systems

摘要

This paper describes a formal standardized procedure for the decision-making process for the purchase or rejection of an information storage and retrieval system. The interaction of both the purchaser of the system and its potential users with the various models of the system (such as cost-time-volume models and performance evaluation models) ensures that the purchase decision for a given system is affected by all possible constraints and is universally acceptable. If either purchaser or users find a particular system unacceptable, the procedure either rejects it or institutes modifications (within given constraints) until a generally acceptable system is determined, if one exists.
