On the basis of the evaluation of the network slacks-based measure(SBM) model, the maximum frontier set of the production system is selected as reference sets. The network SBM evaluation method based on the maximum frontier set is built, in which the multi-stage complex production system exists in internal sub-processes. The model reflects that the optimal path of the inefficient production unit is improved as efficiency. By taking the value distribution of inputs, intermediate products and outputs in the sub-process as its weights to introduce into the model, the practicability of the model is enhanced. Finally, an example is given to verify the effectiveness of the model in efficiency evaluation of the multi-stage correlated complex production system.
