Abstract: The present invention provides systems and related methods for forming a market response model (“MRM”) for modeling the probability of winning a price quote to a prospect or customer. Such a MRM may thereafter be used to estimate the probability of winning a bid to sell a product or service to a particular customer at a particular price against specific competition. In preferred embodiments, the process of developing a particular MRM for use in optimizing a bid entails the steps of acquiring historical data; creating an analysis data set from the historical data; exploring the data sets and identifying segments; defining an MRM structure using the segments; and validating the MRM. Embodiments of the present invention provide systems and related methods for forming a MRM for modeling the probability of winning a price quote to a prospect or customer.
