【摘要】：經(jīng)濟(jì)在發(fā)展，企業(yè)之間的競(jìng)爭(zhēng)也在隨之發(fā)展。一改以往企業(yè)與企業(yè)、行業(yè)與行業(yè)之間的競(jìng)爭(zhēng)狀況，現(xiàn)如今已經(jīng)發(fā)展成跨企業(yè)、跨行業(yè)甚至跨國的供應(yīng)鏈競(jìng)爭(zhēng)。在此背景下，關(guān)于水產(chǎn)品供應(yīng)鏈的研究也就變得日益炙熱化。上海市的水產(chǎn)品消費(fèi)量巨大，水產(chǎn)品加工行業(yè)卻遠(yuǎn)遠(yuǎn)落后于我國平均水平，所以針對(duì)上海市的水產(chǎn)品供應(yīng)鏈研究是有意義的，以水產(chǎn)品加工企業(yè)作為供應(yīng)鏈的核心企業(yè)來研究更具有現(xiàn)實(shí)意義。 本文首先從國內(nèi)外的角度分析了關(guān)于水產(chǎn)品供應(yīng)鏈的優(yōu)化方法及其風(fēng)險(xiǎn)管理研究，得出目前很少有研究將水產(chǎn)品供應(yīng)鏈中的風(fēng)險(xiǎn)水平考慮到供應(yīng)鏈整體優(yōu)化目標(biāo)中來的結(jié)論。然后分析了上海市水產(chǎn)品供應(yīng)鏈現(xiàn)狀，突出強(qiáng)調(diào)了上海市水產(chǎn)品消費(fèi)需求巨大但加工企業(yè)遠(yuǎn)遠(yuǎn)落后于國家平均水平的現(xiàn)狀。本文以此提出以上海市水產(chǎn)品加工企業(yè)為供應(yīng)鏈核心，通過引進(jìn)條件風(fēng)險(xiǎn)價(jià)值理論，分別度量供應(yīng)網(wǎng)絡(luò)和分銷網(wǎng)絡(luò)的風(fēng)險(xiǎn)水平，在此基礎(chǔ)上，創(chuàng)新性地分別建立了以降低供應(yīng)鏈風(fēng)險(xiǎn)損失為目標(biāo)之一的優(yōu)化模型。以上海市某水產(chǎn)品加工企業(yè)為例，，將調(diào)查的相關(guān)數(shù)據(jù)代入模型并求解，分別得出了該加工企業(yè)在供應(yīng)網(wǎng)絡(luò)風(fēng)險(xiǎn)環(huán)境下的供應(yīng)商選擇和采購量決策方案和分銷網(wǎng)絡(luò)風(fēng)險(xiǎn)環(huán)境下的最佳分銷點(diǎn)選擇和各需求點(diǎn)采購量決策方案。 本文研究表明：將條件風(fēng)險(xiǎn)價(jià)值運(yùn)用到供應(yīng)鏈優(yōu)化設(shè)計(jì)中來，是具有創(chuàng)新性和實(shí)用性的，可以為供應(yīng)鏈核心企業(yè)提供更有效的決策方案；供應(yīng)網(wǎng)絡(luò)中，在核心企業(yè)對(duì)風(fēng)險(xiǎn)態(tài)度一定的條件下，通過兩階段模型可以得到同時(shí)考慮風(fēng)險(xiǎn)水平最低和期望成本最小的最優(yōu)決策，同時(shí)，核心企業(yè)的風(fēng)險(xiǎn)偏好程度會(huì)影響條件風(fēng)險(xiǎn)價(jià)值水平從而影響最終的供應(yīng)商選擇和采購量決策；分銷網(wǎng)絡(luò)中，核心企業(yè)可以實(shí)現(xiàn)多目標(biāo)，即收益水平最大、條件風(fēng)險(xiǎn)價(jià)值水平和客戶滿意度水平最高，同時(shí)，核心企業(yè)對(duì)這三者的重視程度不同會(huì)影響到綜合目標(biāo)值從而影響最終的分銷點(diǎn)選擇和各需求點(diǎn)采購量決策。 本文研究不僅豐富了供應(yīng)鏈及風(fēng)險(xiǎn)管理理論，將普遍運(yùn)用于金融經(jīng)濟(jì)領(lǐng)域的風(fēng)險(xiǎn)度量工具CVaR運(yùn)用到水產(chǎn)品供應(yīng)鏈優(yōu)化中來，拓展了CVaR應(yīng)用范圍的同時(shí)為風(fēng)險(xiǎn)視角下的水產(chǎn)品供應(yīng)鏈優(yōu)化方法提供了新方向，這為上海市水產(chǎn)品加工企業(yè)降低成本、減少風(fēng)險(xiǎn)帶來的損失和提高客戶滿意度提供了依據(jù)和方法。
[Abstract]:With the development of economy, the competition between enterprises is also developing. In the past, the competition between enterprises and enterprises, industries and industries has developed into cross-enterprise, cross-industry and even transnational supply chain competition. In this context, the research on the supply chain of aquatic products has become increasingly hot. The consumption of aquatic products in Shanghai is huge, but the aquatic product processing industry lags far behind the average level of our country, so it is meaningful to study the supply chain of aquatic products in Shanghai. It is of practical significance to study aquatic product processing enterprises as the core enterprises of supply chain. This paper first analyzes the optimization methods and risk management of aquatic product supply chain from the point of view of domestic and foreign, and draws the conclusion that the risk level in aquatic product supply chain is taken into account in the overall optimization goal of supply chain. Then it analyzes the current situation of aquatic product supply chain in Shanghai, and highlights the situation that the consumption demand of aquatic products in Shanghai is huge, but the processing enterprises lag far behind the national average level. In this paper, the supply chain core of Shanghai aquatic products processing enterprises is put forward, and the risk level of supply network and distribution network is measured by introducing the theory of conditional risk value. The optimization models with the aim of reducing the risk loss of supply chain are established innovatively. Taking an aquatic product processing enterprise in Shanghai as an example, the relevant data of the investigation are substituted into the model and solved. The decision scheme of supplier selection and purchasing quantity in the supply network risk environment and the optimal distribution point selection and purchase quantity decision scheme in the distribution network risk environment are obtained respectively. This paper shows that the application of conditional risk value to supply chain optimization design is innovative and practical, which can provide more effective decision making scheme for supply chain core enterprises, supply network, supply network, Under the condition that the core enterprise has a certain attitude to risk, the optimal decision with the lowest risk level and the lowest expected cost can be obtained by the two-stage model, and at the same time, The degree of risk preference of the core enterprise will affect the conditional risk value level and the final supplier selection and purchasing quantity decision. In the distribution network, the core enterprise can achieve multi-objective, that is, the maximum profit level. The level of conditional risk value and customer satisfaction is the highest. At the same time, the different degree of attention to these three factors will affect the comprehensive target value and the final choice of distribution point and the decision of purchasing quantity of each demand point. This paper not only enriches the theory of supply chain and risk management, but also applies the risk measurement tool CVaR, which is widely used in the field of finance and economy, to the optimization of supply chain of aquatic products. It expands the application scope of CVaR and provides a new direction for the optimization of aquatic product supply chain from the risk perspective, which reduces the cost of aquatic product processing enterprises in Shanghai. Reducing risk and improving customer satisfaction provide the basis and method.
