Supply chain grounded on information theory: criterion weighting and its explication of a hierarchical economic information filtering model of supplier selection

This paper explicates the criterion system weighting and importance sequence of supplier selection synthetically, in terms of hierarchy economic information filtering model, multiple turns of feedback from the management staff in manufacturing industries as well as analytic hierarchy process. Hierarchy economic information filtering model helps increase the probability of gaining valid information in supplier selection. The criterion system in the model is the valid information collection in supplier selection. The mean of dyadic comparisons among each hierarchy criterion is the degree of information relative importance in supplier selection. The results of each hierarchy criterion sequence are the importance sequencing of the information weight in valid information collection in supplier selection. Hierarchy economic information filtering model defines the information search criterion of supplier selection. It helps increase information search efficiency, save information search time and reduce cost. It helps dynamic supplier information filtrate, select, treat and response in real time.
