Unification of the requirements to parameters of semi-manufactures in designing of multivariant products

Frequently the different customers formulate different technical requirements (TR) to the same product. So the nomenclature groups of products are formed. Such products are named as "multivariant products". In designing there is the necessity to solve the inverse problem: to determine the unified requirements to parameters of semi-manufactures (tolerances) in dependence upon the requirements to the output characteristics of the product.
