Engines, methods, and systems for normalizing heterogeneous parameters for scoring proposals

摘要

The invention includes a tradeoff module having a range of values, a criteria behavior module that analyzes attributes including values of the criteria for a set of alternatives, generating a set of scores reflecting the desirability of the attributes using logic diagrams, and a scoring and ranking module that utilizes assigned values from the tradeoff module and the set of scores from the criteria behavior module to generate a ranked list of alternatives. The invention is used to facilitate a reverse auction, where suppliers submit bids to a purchaser desiring specific goods or services. The invention discloses a system for generating a ranked list of alternatives, including means for generating a homogeneous matrix of scores based on a heterogeneous matrix of attributes and alternatives, means for receiving a tradeoff value, and means for generating a ranked list of alternatives based on the homogeneous matrix of scores and the tradeoff value.
