Case-Based Reasoning (CBR) is a method of designing new product configurations based on previous design case matching. Over the last couple of decades, CBR has grown from a relatively isolated research area to a comprehensive and multi-field one. Extenics is one of fields combined with it. The representation model and extension distance theory in Extenics are surveyed. Based on dependence function, an improved comprehensive evaluation of configuration schemes of a complex modularized product is proposed, considering the interface matching problem that may occur between different components. To illustrate the validity and feasibility of our method, a design case of artillery system is described. The result shows that our evaluation method can better adapt to engineering practice and provide effective and reasonable matching results.
