Abstract:

In view of the influence of design change on the construction cost in the subsequent batch ordering of ships, combined with the reduction effect of cumulative construction lot size on the ship cost, the European distance method is proposed to calculate the similarity before and after the design change of ship, and the batch order cost estimation model after the design change is constructed according to the similarity. On this basis, aiming at the different ship order quantities, according to the two situations of cost saving and overspending in the first batch of ship order, the incentive tiered pricing model for cost saving and the incentive tiered pricing model for cost overspending under the design change are constructed by adjusting the target price and the target profit, respectively. When the estimated cost is consistent with the actual cost, the incentive tiered pricing model for cost overspending degenerates into a cost plus model. Finally, an example is given to verify the feasibility and effectiveness of the proposed model.
