Material information(MI) is very useful for supporting design decision-making. In deep analysisof the product and process design decision-making needs of material information

material information requiremen tframework for supporting design decision is built

and on this basis

the XML-based representation of three layers of MI model is proposed

that is

the underlying layer

logical layer

and application layer. Finally

from the application layer

decision-supported manufacturing quality information feature model is built based on IDEF0.
