Abstract: Based on numerical values with respect to factors influencing shares of existing products and a new product evaluated by more than one people, a structured neural network calculates predictive shares of the new product predicted by the respective persons. Comprehensive evaluations on the respective products and the new product are calculated for each person, based on the numerical values with respect to the respective factors.
