Correct pricing becomes increasingly a key competitive factor for the tool and mould manufacturing industries. However, pricing is characterized by an inconsistent and subjective supply calculation, especially in the customized production area. In addition, dynamic costs, which have a decisive influence on pricing, are not regarded with adequate attention. This paper presents an approach that allows for a statement on the offered price related to time dynamic costs. Furthermore, the approach permits propositions concerning the probability with which an estimated price occurs based on the enterprise related aggregation of knowledge.
