Abstract: A device and associated method for formulating, via an information technology device having a user interface, a numerical model of manufactured products, the numerical model including components, variables and constraints executes different steps successively. Each step stores, via the information technology device, the predetermined numerical data in order to construct the numerical model in memory. The numerical model may then be used to create a configuration of the manufactured product by making, via a user interface, choices among the structural, technical, manufacturing, and commercial characteristics of the numerical model of the manufactured product.

Abstract: A device (1) for formulating—on the basis of a data-processing numerical model including several variables, the assuming of values of which is subject to predetermined constraints—a definition of a version of a product. Such a device is suitable to permit a user to effect selections of values to be assigned to each variable, and is suitable to authorize the modification of a value assigned to a variable at the time of a previous selection. Such a device is, in addition, suitable to present to the user the set of the possible values of each variable, taking account of the constraints linking it with the other variables, notably with those which already possess assigned values.
