✦ Synopsis

unctional modeling is an important step in product design, particularly when defining product architecture. Several systematic methods guide the development of functional models and produce graphical representations such as function structures 1-4 . However, functional modeling is rarely considered a quantitative activity. In this paper we introduce the concept of a quantitative functional model-a vector representation of a product in which the number of distinct sub-functions determine the dimension of the vector and the customer need rankings of each sub-function determine the magnitude. By aggregating these models into a product database (a matrix of products and functions), the quantitative functional model represents a powerful new manner of archiving and
