Metody szacowania kosztów na etapie projektowania i kształtowania procesów produkcyjnych

On the stage of product design there is a problem related to production cost estimation in the moment when elements are not yet definitely designed. Depending on the amount of the available information, more or less precise cost estimation methods are applied, i.e.: variant methods, generation methods, hybrid methods. The proposed method of cost estimation is based on a formalized description of information about features of construction, manufacturing and organization related to the designed element, automation method of technological processes design using methods of group technology and a model of production costs of machine elements based on Activity Based Costing.
