Abstract: Starting from the big data application characteristics of current discrete manufacturing processes in workshops, big data collection and processing analyses of the manufacturing processes were realized based on intelligent Agent of the workshops. A big data acquisition model of the manufacturing processes was established to realize the encapsulation of process data set. A clustering-based method was used to perform the outlier detection mark on the process data set to realize the description and quantification of production states of the manufacturing resources. A process level data feature model was established, and an improved similar element analysis method was used to realize the similarity evaluation of multi-level packaging description and manufacturing process of the process data. A underlying intelligent management system of the workshop was developed and applied to the actual productions of the enterprises.
