基于FAHP和FTOPSIS的海洋船舶溢油应急处置方案筛选方法

频繁发生的海上船舶溢油事故对生态环境和社会经济损害巨大,当溢油事故发生时,决策者往往同时面临多种不同的处置方案,此时,如何从这些备选方案中快速选择出相对最合理的处置方案对减小损失尤为重要。本文基于联合使用模糊层次分析法(FAHP)和模糊逼近理想解的排序法(FTOPSIS),提出溢油应急处置方案综合评判筛选模型(FAHP-FTOSIS)。该方法首先从经济、技术、环境、溢油状况、作业环境和溢油位置这六个主要方面构建船舶溢油应急处置方案评判指标体系,通过FAHP确定各指标权重,然后运用FTOPSIS对备选的应急方案进行排序,最终基于模型的分析结果,筛选出最佳的处置方案。最后,本文将该方法进行了案例应用展示方法的有效性。

A method of selecting emergency disposal schemes for marineship oil spill accidents based on the FAHP-FTOPSIS

Frequent occurrences of marine ship oil spill accidents have brought great damage to the socio-economy and ecological environment.When an oil spill accident happens,decision makers often face a variety of disposal schemes at the same time.At this point,in order to reduce loss to the maximum extent, how to choose a relatively effective scheme from these alternatives is extremely important.In this paper,a hybrid methodology was introduced to solve this problem.The analytic tool,named FAHP-FTOPSIS,was built based on Fuzzy Analytic Hierarchy Process(FAHP) and Technique for Order Preference by Similarity to Ideal Solution(FTOPSIS).First,an index system for evaluating marine ship oil spill emergency schemes was constructed.The index system consisted of six main criteria including the economy,technique,environment,oil spill conditions,operation conditions and oil spill location.FAHP was used to create favorable weights.Then,FTOPSIS was used to find the optimal disposal scheme among the alternative schemes.In the end,an application scenario was presented to prove theeffectiveness of this methodology.
