Aimed at the feature of various fieldbus standards and types as well as the selection and evaluation problems confronted with users, the entropy-ideal point method is used for reference in this paper. A fieldbus comprehensive evaluation and selection method that combined fieldbus technical features and based on fieldbus static performance index is proposed, and the corresponding evaluation model is established. Through the construction of evaluation index hierarchy, standardization of every qualitative and quantitative index, and objective weighing, this method takes the proximate object from ideal point as final evaluation optimization object. As a consequence, the decision-making difference caused by the preference of different decision makers is avoided. Through the case study for certain manufacturing industry automaton enterprise, the feasibility and science of this method used in fieldbus comprehensive evaluation and selection are verified.
