Application of CBR for activity-based cost estimation in steel enterprises

For the complexities of production and the limitations and lacks of methods for cost estimation of customized productions, a method for cost estimation based on Case-Based Reasoning was put forward in the steel enterprises. The process flow of the steel productions was analyzed in order to determine every activity in manufacturing steel productions. The descriptive procedure for the cases and the structure of cases database were presented in detail. The algorithm for case retrieving, adapting and learning was presented. The scheme was illustrated and verified by practical applications.
