【正文】 hnical control processes and logistic performance management. Accordingly, logistic interdependencies are illustrated in qualitative influence models that are parable to the block diagrams known from controlsystems theory. An example is shown in fig. 3, the influence model of the productionlogistics process adapted from [10], The qualitative influence models depict the causeandeffect chains linking the logistic performance measures to the parameters modified by logistic planning and control actions, the socalled determinants. Referring to an example from fig. 3, the performance measures of productionlogistics processes throughput time and utilisation are modelled as functions of the controlled variable WIP level. The latter is calculated as the difference between the two manipulated variables actual inpuf and actual outpuf. The values of the manipulated variables are in turn controlled by determinants: the actual input by the determinants actual work content released and actual release date, the actual output by the determinants actual capacity provided and date of capacity provision. Obviously, the first pair of determinants is parameterised as part of the order release, while the second pair depends on capacitycontrol decisions. Fig. 3. Qualitative influence model of production planning and control (adapted from [10]) For the inventory management of procurement and distribution logistics processes, a similar influence model has been developed. Additionally, the coupling variables of the logistic processes have been identified so that causeandeffect chains that extend across process boundaries may be traced as well. Through the use of these models, logisticians can identify all planning and control actions affecting a certain performance measure. Vice versa, they can locate all performance measures that are affected by a certain planning and control action. Qualitative Evaluation of Logistic Interdependencies The Theory of Logistic Operating Curves not only determines the structure of the quahtative influence models presented above. IFA39。 Ensuring the Consistency of Competitive Strategy and Logistic Performance Management Gregor von Cieminski and Peter Nyhuis Institute of Production Systems and Logistics (IFA), Gottfried Wilhelm Leibniz Universitat Hannover, An der Universitat 2, D30823 Garbsen, Germany Email: {cieminski, nyhuis} Abstract Manufacturing panies often merely attain reduced levels of logistic performance due to inconsistencies between their logistic objectives, logistic performance targets and logistic performance management actions. Qualitative influence models represent the interdependencies between these factors on two levels: firstly between logistic objectives, secondly between logistic perfomiance measures and logistic planning and control parameters. Expert knowledge gained from modelling the dynamic behaviour of logistic systems facilitates the interpretation and evaluation of the qualitative influence models. On this basis, consistent logistic objectives can be defined and objectiveoriented planning and control actions can be identified. The modelling insights are integrated into a logistic performance diagnosis procedure and tool that improve logisticians39。首先，生產過程中可能會被分解成制造和裝配過程的組合與可變數量的生產階段和轉移客戶訂單解耦點[6， 11]。最重要的是，模型幫助制造企業(yè)識別那些業(yè)務計劃和控制行動，使他們能夠有效地提高特定的物流績效措施。診斷還指出情況下，應用的規(guī)劃和控制措施不最大限度地發(fā)揮物流性能。在這個階段，物流績效赤字變得顯而易見。在第一階段中， 制造公司正在考慮 收集性能數據 。 計劃和控制動作操縱程度和時間的投入和輸出的生產資源和商店是他們改善物流績效最有效的。 某些目標的價值觀構成的物流流程規(guī)劃值參數在其他進程的設置 值 必須 是 一致的。 定性評價物流相互依賴關系 物流操作曲線理論不僅決定了結構的上面給出的影響模型， IFA 的專業(yè)知識在解釋定量模型理論也有助于一個定性的物流相互依賴關系評價。 圖表 3：關于生產計劃和管制的定性影響模型 對于采購和配送物流過程的庫存管理，一個類 似的影響模型已經開發(fā)了。 3，生產物流過程的“吞吐量”和“利用”為藍本的性能措施作為控制變量“ WIP 水平”的功能。因此，物流相互依存關系定性的影響與控制系統(tǒng)理論從已知的框圖模型所示。主要的觀點是三個方向對應于彼此 在所有三個物流流程的目標。作為一個拓展，圖表 2 展示三個制造公司物流流程的兩套績效的組合。這個理論包括的范圍是分析模型關于物流庫存和生產系統(tǒng)行為。這些模型往往缺乏清楚 地建立物流績效指標和、操作計劃、控制行為之間的關系 過程 是 能夠采取的。再說，這個結構決定了性能目標的準確操作、計劃、和控制行為的一致性必須實現(xiàn)。一個分析過程參考模型的開發(fā)，西門子關注的基礎是供應鏈運作參考模型推導了所謂制造企業(yè)的物流配置。因此，該公司的經營業(yè)績目標和隨之而來的規(guī)劃和控制行動有“高服務水平”和“低延遲交付”或“高送可靠性”和“短的交貨時間”，分別來自主要目標。 2 連接戰(zhàn)略上和操作的物流管理 由于第 1 節(jié)中描述的市場發(fā)展，許多制造企業(yè)采用的競爭策略，基于其物流績效，其物流戰(zhàn)略成為競爭策略。它首先提供了一個大概后果，就是物流戰(zhàn)略管理決策要物流績效管理操作。物流績效目標之間和因為無規(guī)劃和控制參數的不一致，是物流性能過剩的根源之一。競爭優(yōu)勢二分之一的起源來自于策略設計產品或產品系統(tǒng)獨立性。專家認識的得到是來自關于物流系統(tǒng)促進定性的影響模型的解釋和評價的動態(tài)行為的建模。 本科 生 畢業(yè)設計 （ 論文 ） 翻譯
