Abstract

A device and a method for comparing calculations for product components used in different product types. According to the invention, a list of product types, a list of parts valid for all product types, a database comprising descriptions of structural parts and a database comprising calculations for the components is used. The descriptions and calculations relate to one component each on the list of parts and are specific of one product type each. Once a component is input, all descriptions and calculations for said component are determined and compared with each other. Said comparison allows to find the technical reasons for the differences in the calculations for the same component in different product types.

18. The device as recited in claim 17, wherein:

the parts list includes a further breakdown of each component into one or more parts;

at least one calculation in the calculation database includes information about a percentage of a part in the calculation of a respective component;

the comparison unit is configured to generate a partial comparison for each part of the selected component, wherein each partial comparison includes the percentage of the part of the calculation of the comparison.

19. The device as recited in claim 18, wherein the comparison unit is configured to generate a configuration comparison of the characteristics of the features of the parts in the product types and configured to insert the configuration comparison into the comparison.

20. The device as recited in claim 17, further comprising:

a product type selecting unit configured to select product types occurring in the product type listing, and wherein the determining unit is configured to determine all calculations relating to a selected component and a selected product type.

21. The device as recited in claim 17, wherein the calculations relate to costs and further comprising an electronic cost type list including a plurality of cost types for each calculation, the cost type list being valid for all components of the parts list and all product types of the listing, wherein each calculation includes a partial calculation for each cost type in the cost type list, and wherein the comparison unit is configured to break down a comparison into the cost types of the cost type list.

22. The device as recited in claim 21, further comprising a cost type selecting unit configured to select at least one cost type occurring in the cost type list and wherein the comparison unit is configured to automatically remove cost types not selected from the comparison.

23. The device as recited in claim 21, further comprising:

a calculation selecting unit configured to select a calculation contained in the comparison for each cost type of the cost type list; and

a cost type calculation unit configured to generate a calculation for a selected component, each calculation having a partial calculation for a respective cost type of the cost type list, the partial calculation for a cost type being equal to the partial calculation of the calculation selected for the cost type.

24. The device as recited in claim 17, further comprising:

an electronic attribute list having attributes assignable to the calculations and having possible values of the attributes, the attribute list being valid for all components of the parts list and all product types of the listing, wherein the calculations in the calculation database include attribute-attribute value pairs, each attribute occurring in the attribute list and each attribute value being a possible value of the attribute; and

an attribute selecting unit configured to select at least one attribute of the attribute list and one possible value of a selected attribute, wherein the determining unit is configured to automatically determining all calculations including at least one selected attribute-attribute value pair.

25. The device as recited in claim 24, wherein the attribute list includes at least one of the following attributes:

a period of time to which the calculation refers;

a material used to manufacture at least one product component;

a supplier of at least one product component;

a manufacturing method used in the manufacture of at least one product component;

a resource used in the manufacture of at least one product component; and

a region in which at least one product component is manufactured.

26. The device as recited in claim 17, further comprising:

a calculation unit configured to generate the calculations using the electronic parts list; and

a memory unit configured to save the calculations in the calculation database.

27. A method for comparing calculations for product components in different product types, the method comprising:
