摘　　要： 近年来频发的水产品质量问题严重打击了消费者的消费信心,也对水产品的生产、消费及出口造成了严重的负面影响。要想水产业良好发展,必须在全行业中建立一套完整的质量风险管理机制。因此,本文以水产品供应链质量风险为研究对象,提出了融合多种经济管理工具的水产品质量风险管理方案,对我国水产品供应链质量风险管理体系的构建和完善具有一定的参考价值。 本文是从质量风险识别、质量风险评估及质量风险控制三个方面展开论述的,获得的研究成果如下： 第一,水产品供应链质量风险综合评估指标体系的构建。首先分析了“农超对接”模式下水产品供应链的运作流程,然后运用基于价值决策的流程分析方法/(value-focused process engineering, VFPE/)对以罗非鱼为例的水产品供应链质量风险因素进行识别,最后根据质量风险识别结果构建养殖基地和超市的质量风险综合评估指标体系； 第二,水产品供应链质量风险综合评估模型的构建及应用。首先概述了基于三角模糊数和熵函数的模糊层次分析法,然后详细阐述了该方法中两大难点问题的处理过程：一是采用重心法实现风险值的去模糊化；二是通过熵函数和改进的粒子群算法求解群决策环境下专家的权重系数。最后结合风险识别的结果,将该模型用于实际案例分析,得出参与调研的企业均需对自身质量风险管理状况做进一步的改善； 第三,水产品供应链质量风险控制协调模型的构建、分析及应用。鉴于企业需进-步改善质量风险管理状况,本文结合“农超对接”水产品供应链的特点,利用委托-代理理论,构建水产品供应链质量风险控制协调模型,最后采用库恩塔克条件/(KKT/)条件分析供应链上、下游企业资金充足与否4种情况时最佳协作状态下的收益、质量保障水平及投资规模情况。通过实证分析可知：无论是养殖基地还是超市,投资资金充足时的质量保障水平和收益均大于不足时的收益。通过仿真得知：企业的质量保障水平与自身销售价格、销售地质量检测水平、协同企业质量保障水平及产品新鲜度敏感系数呈正相关,与价格敏感系数呈负相关。最后根据这一结论提出相应的质量控制策略。 In recent years, aquatic product quality problems which happen frequently hit theconsumer confidence and have a negative impact on the production, consumption and exportsof aquatic products. In order to improve this situation, It is far significant to establish acomprehensive quality risk management mechanism in the aquaculture industry. So this paperfocus on the quality risk of aquatic supply chain and proposes an aquatic product quality riskmanagement approach with integrating a variety of economic management tools, which ishelpful for the establishment and improvement of the management system of quality risk ofaquatic supply chain to a certain extent. This paper starts discussion from three aspects of the quality risk recognition, quality riskassessment and quality risk control. The specific research results are as follows: /(1/)The establishment of comprehensive evaluation index system of aquatic supply chainquality risk. First, analyze the operation processes of the aquatic supply chain under farmingsupermarket docking; then, identify the quality risk issues of aquatic products in tilapiaexample with value-focused process engineering /(VFPE/); finally, build a quality riskcomprehensive evaluation index system based on the recognition results. /(2/)The establishment and application of the quality risk assessment model of aquaticsupply chain. First, make use of triangular fuzzy numbers to quantize the hazardous of riskand the probability of risk, and adopt the center of gravity method to achieve a defuzzificationrisk worth; then, build the model of group decision-making expert weight based on maximumentropy and relative entropy theory. And the model is solved by the particle swarmoptimization /(PSO/) with competition mechanism and mutation mechanism; finally, empiricalanalysis shows that the upstream and downstream enterprises in the supply chain both need toimprove the situation of quality risk. /(3/)The establishment, analysis and application of quality risk control coordination modelof aquatic supply chain. First, build the supply chain coordination model to consider thequality parameters based on 'farming supermarket docking' and the principal-agent theory;then through the Karush-Kuhn-Tucker /(KKT/) to analysis the earnings, the best level of quality assurance and investment scale under different capital position. Then, empiricalanalysis shows that the income and quality level of breeding base or supermarkets are greaterthan the low investment funds. The simulation results show that the level of quality assuranceis positively correlated with its own sales prices, the level of sales quality testing, the level ofquality assurance of collaborative enterprises, the product freshness sensitive coefficient and asingle batch of product sales time. And it is negatively correlated with price-sensitive. Finally,according to this conclusion this paper put forward corresponding quality control strategy.
