  abstract =     "One of the orientations of the tool-making industry is
                 towards shortening the time from enquiry to the supply
                 of tools. The tool-making shops must prepare within the
                 shortest possible time an offer for the manufacturer of
                 the tool based on the enquiry in the form of the
                 CAD-model of the final product. For preparation of a
                 proper offer, the values of certain technological
                 features occurring in the manufacture of the tool are
                 needed. Most frequently the tool manufacturer is
                 interested in total cost for manufacture of the tool.
                 Because of lack of time for making a detailed analysis
                 the total costs of tool manufacture are predicted by
                 the expert on the basis of the experience gathered
                 during several years of work in this area. In our work,
                 we conceived an intelligent system for predicting of
                 total cost of the tool manufacture. We limited
                 ourselves to tools for manufacture of sheet metal
                 products by stamping; the system is based on the
                 concept of case-based reasoning. On the basis of target
                 and source cases, the system prepares the prediction of
                 costs. The target case is the CAD-model in whose costs
                 we are interested, whereas the source cases are the
                 CAD-model of products, for which the tools had already
                 been made, and the relevant total costs are known. The
                 system first abstracts from CAD-models the geometrical
                 features, and then it calculates the similarities
                 between the source cases and target case. Then the most
                 similar cases are used for preparation of prediction by
                 genetic programming method. The genetic programming
                 method provides the model connecting the individual
                 geometrical features with total costs searched for. In
                 the experimental work, we made a system adapted for
                 predicting of tool costs used for tool manufacture on
                 the basis of a theoretic model. The results show that
                 the quality of predictions made by the intelligent
                 system is comparable to the quality assured by the
                 experienced expert.",
