Patent ID: 6863213

Claim:
A method for providing a decision support for users for selecting a at least one of a drilling element and a cutting element for use in a construction material region, comprising the steps of grouping areas of application of aggregates for concrete as a factor of different at least one of a drilling resistance and cutting resistance of the aggregates into zones ( 12 , 13 , 14 ) in a geographical information storage medium ( 10 ); associating each of said zones ( 12 , 13 , 14 ) with a reference number ( 15 , 16 , 17 ) that reflects a specific magnitude of at least one of a drilling resistance and cutting resistance; and providing the at least one of the drilling element and cutting element ( 20 ) to be used in an area of application of aggregate materials of a specific at least one of the drilling resistance and cutting resistance with a corresponding reference number ( 25 , 26 , 27 ) corresponding to the reference numbers ( 15 , 16 , 17 ) of the zones.
