基于MAS的供應(yīng)鏈突發(fā)事件應(yīng)急協(xié)調(diào)機(jī)制研究.pdf

1、摘要隨著全球經(jīng)濟(jì)的迅速發(fā)展和市場競爭的日益激烈，企業(yè)正面臨著更大的挑戰(zhàn)和機(jī)遇，而供應(yīng)鏈管理作為提升企業(yè)市場競爭力的重要手段，越來越受到企業(yè)管理者的重視。由于供應(yīng)鏈所處的環(huán)境并非持續(xù)穩(wěn)定的，經(jīng)常會遇到各種各樣的突發(fā)狀況，如果不能及時處理，往往會給供應(yīng)鏈系統(tǒng)帶來巨大的損失。供應(yīng)鏈應(yīng)急協(xié)調(diào)作為供應(yīng)鏈管理的重要內(nèi)容之一，對于應(yīng)對供應(yīng)鏈中突發(fā)事件，改善供應(yīng)鏈系統(tǒng)性能具有實際意義。本文將多Agent技術(shù)引入到供應(yīng)鏈管理中，通過建立由單供應(yīng)商和單零售

2、商組成的二級供應(yīng)鏈MAS模型，對突發(fā)事件下的供應(yīng)鏈應(yīng)急協(xié)調(diào)機(jī)制進(jìn)行了研究。本文的主要研究內(nèi)容如下：闡述了供應(yīng)鏈突發(fā)事件、供應(yīng)鏈協(xié)調(diào)以及多Agent技術(shù)方面的相關(guān)理論，通過分析得出了將多Agent技術(shù)引入供應(yīng)鏈管理，實現(xiàn)多Agent供應(yīng)鏈建模的可行性，并給出了多Agent供應(yīng)鏈建模的流程?；诙郃gent技術(shù)建立了二級供應(yīng)鏈系統(tǒng)的靜態(tài)和動態(tài)模型，著重對動態(tài)模型進(jìn)行了分析與計算。在假設(shè)市場需求為零售價格的負(fù)指數(shù)函數(shù)和供應(yīng)商為Stackelb

3、erg博弈主導(dǎo)者前提下，當(dāng)突發(fā)事件造成市場規(guī)模和價格敏感系數(shù)同時發(fā)生擾動，供應(yīng)鏈外部環(huán)境發(fā)生變化帶來額外成本時，給出了調(diào)整生產(chǎn)計劃和零售價格的最優(yōu)應(yīng)對策略，并提出了新的數(shù)量折扣契約，使得在該契約下，供應(yīng)商和零售商的利潤能夠合理分配。通過對模型進(jìn)行仿真，進(jìn)一步分析了當(dāng)突發(fā)事件造成擾動時，是否采用應(yīng)急協(xié)調(diào)機(jī)制對供應(yīng)商、零售商和供應(yīng)鏈整體利潤的影響。從仿真結(jié)果可以得出，采用應(yīng)急協(xié)調(diào)策略能夠在確保供應(yīng)商和零售商利潤均大于零的前提下，實現(xiàn)供應(yīng)鏈整

4、體利潤的最大化，驗證了應(yīng)急協(xié)調(diào)機(jī)制的有效性。關(guān)鍵詞：供應(yīng)鏈管理；應(yīng)急協(xié)調(diào)機(jī)制；多Agent技術(shù)；擾動；數(shù)量折扣契約，一奄AbstractWiththerapiddevelopmentofglobaleconomyandincreasinglyfiercemarketcompetitionenterprisesarefacingwithgreaterchallengesandopportunitiesSupplychainmanageme
