维修保障船与修船厂维修远海受损舰船的定价博弈

维修保障船能够实现远海受损舰船的现场维修,当其进入舰船维修市场时将与修船厂形成一定程度的竞争。为解决维修保障船模式与修船厂模式维修远海受损舰船的最优定价问题,通过分析这两种维修模式在时空以及成本方面的差异,建立维修保障船与修船厂的定价博弈双层规划模型,并设计迭代算法实现模型的求解。以维修远海船体受损的舰船为例,求得了两者的最优定价、最大收益以及船东对两种维修模式的需求,验证了模型与算法的有效性,并分析了调遣距离、舰船受损程度、海上维修技术难度等因素对维修保障船与修船厂定价博弈的影响。该方法能够为维修保障船与修船厂的经营者提供最优定价策略,为两种维修模式的定价博弈提供理论支持。

Pricing Game between Repair and Support Ships and Shipyards for Repairing Damaged Ships at Sea

Repair and support ships could carry out spot maintenance and repair for damaged ships at sea, and would compete with shipyards when entering the maintenance and repair market for ships. In order to solve the optimal pricing problem between repair and support ships and shipyards to repair damaged ships at sea, a pricing game model between repair and support ships and shipyards is established by analyzing the differences in space, time and cost between the repair and support ship modes and shipyard modes. An iterative algorithm is designed to solve this bi-level programming model. Taking a maintenance and repair work of a ship with damaged hulls at sea as an example, the optimal pricing and maximum benefits of repair and support ships and shipyards, and the requirements of ship owners for these two maintenance and repair modes are obtained, which verifies the validity of the model and algorithm. The influence rules of some factors such as dispatch distance, damage degree of ships and difficulty of marine maintenance and repair technology on the pricing of repair and support ships and shipyards is analyzed. This method can provide optimal pricing strategy for operators of repair and support ships and shipyards, and provide theoretical support for pricing game of these two maintenance and repair modes.
