摘要:

针对舰船后续批次订货中设计变更对建造成本的影响, 结合累积建造批量对舰船成本的降低作用, 提出采用欧式距离法计算舰船设计变更前后的相似度, 并根据相似度构建设计变更后的批量订货成本估算模型。在此基础上, 针对不同的舰船订货批量, 根据舰船首批次订货成本节约和超支两种情况, 分别通过调整目标价格和目标利润, 构建设计变更下面向成本节约的激励性梯次定价模型和面向成本超支的激励性梯次定价模型, 且在估计成本与实际成本一致时, 面向成本超支的激励性梯次定价模型退化为成本加成模型。最后通过算例验证了所提模型的可行性和有效性。

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.

Key words: ship, design change, batch order, tiered pricing, similarity
