Knowledge Recommendation Method for Concept Development of Manufacturing Technology Using Morphological Similarity

Concept development is the first and most knowledge-intensive step in the development process of manufacturing technology. Its core is to find a solid scientific foundation for the manufacturing requirements in order to propose a feasible manufacturing technology concept. However, the lack of formal methods and finiteness of personal knowledge result in high randomness and low efficiency of this step. This paper presents a formal design knowledge recommendation method for manufacturing technology concept development by calculating the morphological similarity between manufacturing requirements and multi-domain effect knowledge. In this method, the morphological matrix of general manufacturing technology is constructed first as a template. Then, manufacturing requirements and multi-domain effect knowledge are both expressed as matrices based on this template. Finally, through quantitatively calculating the normalized weighted Euclidean distance between manufacturing requirements and multi-domain effect kno...
