Rule-based quotation costing of pressure die casting moulds

摘要

An actual analysis in the tool and mould making sector showed that methods and programs insufficiently support the manufacturers of pressure die casting moulds in the quotation costing process. The primary aim of quotation costing is to generate many first-class bids in order to gain a high quantity of profitable orders. For this purpose companies have to achieve a high calculation precision with low expenditure. In addition, a comprehensible calculation is of great importance in order to enable an internal and external comparability and analysis as well as to permit the customer to assess the performance offered. In order to support companies of the tool and mould making concerning these matters, a working group from industry and science analyzed the quotation costing made by manufacturers of pressure die casting moulds. The article discusses the results of this analysis and describes the development of a rule-based calculation approach.
