Abstract: To evaluate the effectiveness of investment decision for manufacturing systems, the system input was decomposed as information flow, material flow and energy flow while the system output was decomposed as stability, quality of self-organization and integrity, all of which were expressed separately by certain measurable parameters. Then a C2R Data Envelopment Analysis (DEA) decision model with multi-input and output was built to assess whether technique and scale were simultaneously efficient. To appraise the technical efficiency of manufacturing system alone, the C2R model was extended to a C2GS2 model, and to introduce the decision maker's subjective preference, the C2R model was extended to a C2WH model with preference cone.

Key words: C2R decision model, data envelopment analysis effectiveness, information flow, material flow, energy flow
