3、,加上自然災(zāi)害等突發(fā)事件的頻繁發(fā)生,使供應(yīng)鏈變得越來(lái)越脆弱,面臨的供應(yīng)鏈風(fēng)險(xiǎn)也越來(lái)越高。供應(yīng)中斷就是眾多供應(yīng)鏈風(fēng)險(xiǎn)中較為重要的一種,且大量的案例告訴我們,供應(yīng)中斷事件發(fā)生會(huì)使供應(yīng)鏈下游企業(yè)由于匱乏生產(chǎn)資源導(dǎo)致停產(chǎn),甚至?xí)沟蒙舷掠纹髽I(yè)脫節(jié),最終給企業(yè)和供應(yīng)鏈帶來(lái)巨大的經(jīng)濟(jì)損失。故本文以四級(jí)供應(yīng)鏈網(wǎng)絡(luò)為研究對(duì)象,從整個(gè)供應(yīng)鏈運(yùn)行成本視角下,針對(duì)制造商在供應(yīng)中斷風(fēng)險(xiǎn)下的采購(gòu)策略問(wèn)題做相關(guān)研究。首先根據(jù)供應(yīng)鏈成本構(gòu)成的基本知識(shí)以及相關(guān)的文獻(xiàn),引入時(shí)間變量,構(gòu)建在滿足最低訂單滿足率下的動(dòng)態(tài)供應(yīng)鏈網(wǎng)絡(luò)成本優(yōu)化模型。其次,在動(dòng)態(tài)供應(yīng)鏈成本模型基礎(chǔ)上,引入供應(yīng)中斷
4、概率和中斷持續(xù)時(shí)間,建立部分供應(yīng)中斷風(fēng)險(xiǎn)下制造商的采購(gòu)策略模型。最后,根據(jù)具體企業(yè)案例,使用Arena軟件建立四級(jí)供應(yīng)鏈仿真模型,針對(duì)動(dòng)態(tài)供應(yīng)鏈成本優(yōu)化模型采用基于Optquest的仿真模型求解各個(gè)定期訂貨節(jié)點(diǎn)的目標(biāo)庫(kù)存;針對(duì)部分供應(yīng)中斷風(fēng)險(xiǎn)下制造商的采購(gòu)模型,采用仿真模型求解模型結(jié)果,得出制造商K的采購(gòu)策略,并且在模型結(jié)果的基礎(chǔ)上,討論供應(yīng)中斷概率的臨界值。關(guān)鍵詞:動(dòng)態(tài)供應(yīng)鏈,成本模型,采購(gòu)策略,仿真分析I英文摘要ABSTRACTWiththeglobalizationofeconomics,specializationoflaborandglob
