Using causality analysis in the beef quality information tracing

Causal relation analysis is a promising application in product quality tracking and tracing. Considering the quality safety problems in China beef production, the causal relation analysis was introduced into the beef quality safety tracing system and a causal approach-based tracing method was proposed. Considering the implicity, complexity and dynamic characteristics in beef quality safety causal relations, based on its mechanisms, a beef quality safety event representation method was studied based on the extended spanning tree structure. And the detection algorithm was developed based on an improved minimum spanning tree method. With consideration of the time relations, hierarchical relations and causal relation between the beef quality safety events, an approach was proposed for the output of hierarchy view and solution of the causal tracing problems. Finally, through the investigation in the beef production manufactures, the proposed method got sound validation.
