Many intangible criteria can influence the priorities and ranks of inventions as they contribute to human welfare. A new, unique approach by using the Analytic Hierarchy Process has recently been presented. The work which breaks new ground about the numerical prioritization of all kinds of inventions is applied to evaluate a number of modern inventions along with old ones. Both the categories of inventions and the effects they have on human well-being and human progress are considered in the weighting process. Different effects of similar types of inventions can have different properties. Significant effort is spent in structuring the process in a comprehensive hierarchy.
