Cost Allocation Design of Commercial Aircraft Based on Function

Cost management is the core of the management of commercial aircraft company,decomposing the cost of the aircraft is a key part of the management of commercial aircraft.The polynomial approximation is proposed to solve the cost allocation problem for commercial aircrafts.By making up polynomial function,each part cost of the commercial aircrafts is given in the proportion of the total cost,and provided the basis of the management of the aircraft.Considering the total cost which needs to be cut under certain,a robin algorithmis constructed that is given the cut number of each part and the proportion of the cost reduction.The algorithm is proved to be true by studying case.
