【摘要】：在經(jīng)濟(jì)全球化、發(fā)達(dá)的信息技術(shù)時(shí)代的市場競爭比傳統(tǒng)市場的競爭更加激烈，競爭方式已從企業(yè)間的競爭已轉(zhuǎn)變?yōu)楣⿷?yīng)鏈間的競爭，供應(yīng)鏈的核心競爭力體現(xiàn)在企業(yè)成員間的相互協(xié)作來抵抗風(fēng)險(xiǎn)事件的能力。然而，在逐漸開放的市場內(nèi)，用戶需求不確定性、企業(yè)間合作的多變性、企業(yè)經(jīng)營目標(biāo)的矛盾性、業(yè)務(wù)復(fù)雜性以及貿(mào)易壁壘政治因素、政治和民族文化問題、自然災(zāi)害等的發(fā)生等，使得供應(yīng)鏈可靠性受到極大的威脅。因此，供應(yīng)鏈系統(tǒng)可靠性的研究具有重要的理論與實(shí)際意義。 本文在分析供應(yīng)鏈流程和功能的基礎(chǔ)上，結(jié)合可靠性理論，建立含2個(gè)采購商、2個(gè)生產(chǎn)商、1個(gè)分銷商、1個(gè)零售商的供應(yīng)鏈模型，對供應(yīng)鏈系統(tǒng)內(nèi)出現(xiàn)的因天氣、人員、設(shè)備、技術(shù)導(dǎo)致風(fēng)險(xiǎn)事件進(jìn)行分析，構(gòu)建系統(tǒng)狀態(tài)轉(zhuǎn)移圖，建立并求解微分方程，利用Markov、概率分析、Laplace變換、補(bǔ)充變量法等求出系統(tǒng)正常、4種異常、9種故障狀態(tài)下時(shí)間、頻度、次數(shù)等可靠性指標(biāo)，在綜合計(jì)算供應(yīng)鏈系統(tǒng)的收益、修理費(fèi)用各項(xiàng)費(fèi)用的條件下，列出供應(yīng)鏈系統(tǒng)的利潤函數(shù)，文末給出了一個(gè)算例，，驗(yàn)證模型可靠性，并對供應(yīng)鏈系統(tǒng)的運(yùn)營管理給出了具體建議。
[Abstract]:In the economic globalization, the market competition in the developed information technology age is more intense than the traditional market competition, the competition mode has changed from the competition among enterprises to the competition between supply chains. The core competence of the supply chain is reflected in the ability of the members of the enterprise to cooperate with each other to resist the risk events. However, in the gradually open market, the uncertainty of user demand, the variability of the cooperation between enterprises, the contradiction of the business objectives, The complexity of business and the political factors of trade barriers, political and national cultural problems, natural disasters and so on, make the reliability of supply chain greatly threatened. The research of supply chain system reliability has important theoretical and practical significance. Based on the analysis of supply chain flow and function and reliability theory, a supply chain model with 2 buyers, 2 manufacturers, 1 distributor and 1 retailer is established. The technology causes risk events to be analyzed, system state transition diagrams are constructed, differential equations are established and solved. By using Markov-probability analysis Laplace transform and supplementary variable method, the time and frequency of 9 abnormal states of the system are obtained. Under the condition of synthetically calculating the profit and repair expenses of the supply chain system, the profit function of the supply chain system is listed. At the end of this paper, an example is given to verify the reliability of the model. And the operation and management of the supply chain system is given specific suggestions.
