Abstract: Direct maintenance cost allocation of civil aircraft is an important economic design step in aircraft development. The allocation method of civil aircraft maintenance cost is studied, using the entropy weight-TOPSIS method to determine the weight of design parameters of similar models, and using the weight distance to calculate the similarity of models. The results show that this method is more accurate than the functional decomposition method and the function approximation method, and that the model proposed is effective.

Key words: direct maintenance cost, distribution model, entropy value method, TOPSIS, weighted distance
