基于Shapley值的港口船舶清污协议费费率定价方法研究
Operations Research and Management Science（2017）
Abstract
针对我国港口船舶清污协议费的定价问题,兼顾公平与效率原则,在根据船舶在港口发生污染事故的风险水平划分其风险等级的基础上,运用Shapley值的简化公式对港口清污资源的总配置成本进行分摊,计算得出每艘船舶每天所需分摊的配置成本,消除了短期船舶靠泊的动态性对分摊结果的影响,是制订港口清污费费率征收标准的理论依据.算例分析结果表明现行船舶清污协议费征收标准过高,本文计算的分摊结果兼顾了公平与效率的原则,并且证明了其满足个体理性,集体理性以及联盟稳定性的要求.
