基于不确定需求的港口柔性靠泊计划

Flexible Port Berthing Plan Based on Uncertain Demands

港口生产系统中存在许多不确定因素,实施高度灵活、富有弹性和对市场需求能够快速响应的港口生产柔性化战略,有利于提升港口综合竞争力,推动港口发展和升级换代。在分析基于不确定需求的港口柔性靠泊服务需求的基础上,研究港口柔性靠泊计划,建立了柔性靠泊计划模型。该模型引入非对称性田口损失函数来衡量服务损失的大小,实现在保证一定服务水平(满意率)的前提下,港口的服务损失最小,即所有在港船舶的时间(费用)损失最小。

There are many uncertain factors in port production systems.Implement of flexible production strategy that can rapidly respond to market demands is beneficial to strengthen port＇s overall competitiveness and promote port upgrading.By analyzing uncertain port berthing service demands,flexible port berthing plan is studied and its model is set up.In this model the asymmetric Taguchi quality loss function is introduced as a measurement of port service loss.This plan reduces the port service losses to a minimum in the precondition of ensuring satisfactory service,i.e.the time or cost losses of all the ships berthing in the port are in minimum.
