Abstract: To mine the key information points from the massive information of distributed control system for evaluating and controlling the information quality based on inherent coupling constraint relationship of process industry,a distributed PageRank algorithm was proposed combined with the characteristics of complex manufacturing systems,which could guarantee the accuracy and reduce the algorithm complexity at the same time.An actual enterprises case was provided to validate the effectiveness and feasibility of the proposed algorithm.

Key words: process industry system, information quality, coupling constraint relationship, distributed PageRank algorithm
