【摘要】:隨著全球經(jīng)濟一體化的持續(xù)發(fā)展,市場競爭的日益激烈,汽車零部件制造企業(yè)已經(jīng)進入了微利時代,面臨嚴峻的成本挑戰(zhàn)。眾多知名的大型汽車零部件制造加工生產(chǎn)企業(yè)僅單一注重對原材料的成本控制,在相當長的一段時間內(nèi)忽視了備件采購的重要性,最終導致了企業(yè)備件的采購的管理高成本,庫存擁有的備件量遠大于維持正常生產(chǎn)運營中所需要的水平,無形中增加了企業(yè)的流動資金被過多占用。備件采購管理在20世紀90年代隨著供應鏈理念的出現(xiàn),以及資本管理不斷得到一些跨國企業(yè)的關注,從而成為了人們爭相開始研究的重要課題。 本論文以企業(yè)備件管理為背景,針對企業(yè)內(nèi)部備件管理不善和備件庫存量高的問題,通過實施ABC分類法、VED分類法以及基于VED的ABC分類法應用,得出了適用于企業(yè)的備件分類方法;其次通過移動平均法、一重指數(shù)平滑法、二重指數(shù)平滑法對企業(yè)內(nèi)部的17款典型備件做需求預測,并且與2012年的實際用量進行比較,得出適合企業(yè)的需求預測方法;建立了基本經(jīng)濟補貨批量、有限補充能力經(jīng)濟補貨批量、補貨提前期的處理和離散型需求經(jīng)濟補貨批量的備件庫存模型,,得出最佳的補貨批量和補貨間隔周期,并且與原有的庫存數(shù)量做出對比,計算出減少的庫存資金占用量。對于使用量大的備件,通過與供應商協(xié)商建立SA(即Schedule Agreement,計劃協(xié)議),達到零庫存的目標。研究探討現(xiàn)代庫存管理手段對降低企業(yè)的采購成本、縮短采購周期、降低庫存等方面帶來的顯著效益,為企業(yè)今后在運營方面的進一步提升提出實際可行的新思路。
[Abstract]:With the continuous development of global economic integration and the increasingly fierce market competition, automobile parts manufacturing enterprises have entered the era of small profits, facing a severe cost challenge. Many well-known large automobile parts manufacturing and manufacturing enterprises only pay attention to the cost control of raw materials, neglect the importance of spare parts procurement for a long time, and finally lead to the high management cost of enterprise spare parts procurement. The quantity of spare parts in stock is much larger than that needed to maintain normal production and operation. With the emergence of supply chain concept and capital management in 1990s, spare parts procurement management has been paid more and more attention by some multinational enterprises, which has become an important subject that people begin to study. This paper takes the enterprise spare parts management as the background, in view of the enterprise internal spare parts management mismanagement and the spare parts inventory high question, through the implementation ABC classification method Ved classification and based on the VED ABC classification method application, The classification method for spare parts is obtained. Secondly, 17 typical spare parts are predicted by moving average method, single exponential smoothing method and double exponential smoothing method, and compared with the actual consumption in 2012. The demand forecasting method suitable for the enterprise is obtained, and the spare parts inventory model of the basic economic replenishment batch, the limited replenishment capacity, the restocking lead time and the discrete spare parts inventory model are established. The optimal replenishment batch and replenishment interval period are obtained, and compared with the original stock quantity, the reduced stock amount is calculated. For spare parts with high usage, set up Schedule agreements with suppliers to achieve zero inventory. This paper discusses the remarkable benefits brought by modern inventory management in reducing the purchasing cost, shortening the purchasing period and reducing the inventory, and puts forward a new practical and feasible way for the further improvement of the operation of the enterprise in the future.
