【中文摘要】 物流系統作爲一個多因素、多目標的複雜系統,從整體上對其進行優化是提高物流領域企業效益、降低成本的必然途徑。供應鏈理論正是從全局的角度對企業的資源進行整合、實施規劃、促進物流各個環節之間協作和資源的合理分配。目前對供應鏈的研究大多單純使用定性或定量分析的方法,但此類方法僅限於基本業務流程的簡單組合,很難實現對複雜業務流程的分析。本文在對供應鏈仿真理論深入研究的基礎之上,爲複雜供應鏈系統建立了層次結構模型,採用企業實際數據對模型加以驗證並提出優化方案,爲參與企業提供輔助的`決策支持。首先,爲了能夠對複雜供應鏈系統進行全面而有效的分析,本文采取了層次化分析的方法,根據SCOR標準由整體到局部的對整個供應鏈流程進行詳細分析和規劃,建立供應鏈層次模型並提出了供應鏈系統績效通用的評價指標體系。其次,本文依託EMERSON海外物流公司的供應鏈系統項目,使用Arena建模工具建立供應鏈仿真系統。這一部分,本文對實際供應鏈系統進行詳細的業務流程分析並根據現實情況對層次化供應鏈模型進行適當調整。然後基於概率論的思想,使用Arena輸入分析器對輸入數據進行處理。運行該系統並將結果與物流企業的真實運作數據進行對比,對模型進行反覆修正,確保模型真實、準確地反映出企業實際的運作流程。最後,對運行結果進行分析、總結並提出優化方案。一方面,從定性的角度爲企業發展提出改善措施;另一方面,通過定義該企業資源配置決策模型,利用Optquest工具的內置遺傳算法對企業資源配置進行定量研究,透析造成瓶頸的根本原因並提出優化的解決方案。使用仿真模型對上述優化方案進行驗證,最終通過定性、定量分析和計算機仿真相結合的方法選擇出最優的方案來輔助決策。本文通過使用仿真建模技術,提出了對複雜供應鏈系統進行分析和優化的一般思路。據此進行建模,案例分析,進而提供優化方案。最終,這些被驗證爲高效的解決方案將對物流領域企業高層決策具有重要的實際意義。
【英文摘要】 As a complex system with multiple controlled constrains and objectives,logistics system should be optimized from an integrated view in order to improve the performance and lower the cost of the supply chain management theory could help coordinate the resource dispatching between nodes of the ver, currently most of the supply chain issues are handled by qualitative or quantitative analysis,limiting the study within the scope of simple business is the reason why there is little academic achievement concerning complex supply chain issue. Based on comprehensive study of the supply chain management and simulation theory, we create a hierarchical supply chain r carefully validation,it could be used to provide associative decision support to the enterprise of tly,we did a hierarchical analysis of the supply chain order to simplify the complex system,we made a considerate analysis from the highest layers to the lowest according to the SCOR ltaneously,we create the evaluation criteria for the supply chain ,use Arena simulation tool to create the model were able to get real data from the Emerson Overseas Logistics d on the theory of Probability Theory,we analyze these statistics and input them by using the Arena input r finishing the simulation execution,we would then compare the results with the real data to repeatedly verify the supply chain system's lly,results come up with improvement solutions by quantity analysis,by quantitative analysis using the Optquest optimizing tool,digging in the real cause of the inefficiency of the supply chain r applying these solutions on supply chain system using Arena,we can verify these solutions' potential g the supply chain simulation model,we present a new method of dealing with complex supply chain system with which we build the hierarchical model,apply it to real cases and raise optimizing solutions ,such proved efficient solutions would definitely make sense and contribute to assisting the decision maker.
