System and method for managing and evaluating network commodities purchasing

摘要

Comparison values are calculated for evaluating a commercial transaction. A request for quote received from a buyer agent includes a product specification data set that identifies items that differ in accordance with at least one parameter. Price data sets received from seller agents identify items and prices in response to the product specification data set. At least one of the price data sets identifies an item having a different parameter value as compared to the item in another price data set. A comparison value for each price data set is generated by determining a price total from the price data set and calculating a summed market price total by summing market price totals for each of the items. Calculating market price totals includes obtaining metric data indicative of market prices. The summed market price total is compared to the price total for the price data set to generate the comparison value.
