【摘要】：當今社會,全球化競爭的主要特征是以需求驅動和快速響應市場機會,使得規(guī)模不斷增大的企業(yè)為了應對客戶需求變化的高速性與高柔性的目的,越來越追求自身運作方式的高效性。在市場競爭環(huán)境日趨激烈的情況下,物流企業(yè)或配送中心必須要找出其具有的核心競爭力及其核心經(jīng)營模式,優(yōu)化配置自身所擁有的資源。在制定長期戰(zhàn)略時,越來越多的企業(yè)會將物流配送納入企業(yè)的競爭戰(zhàn)略,有的甚至把配送能力作為衡量企業(yè)核心競爭能力的重要指標。時間管理是配送中心保持市場競爭力的重要來源,時間競爭的本質(zhì)就是要縮短在配送貨物過程中的時間。因此,配送周期的縮短能夠決定整個物流配送系統(tǒng)能否科學、高效運行的一項核心工作。本研究首先對業(yè)務外包的內(nèi)涵、物流業(yè)務外包的原因、物流配送理論及網(wǎng)絡圖理論進行了闡述,在此基礎上,論述成為物流配送系統(tǒng)關鍵要素應具備的條件。其次,分析了物流配送服務網(wǎng)絡的構成要素及其分類,重新界定了物流配送周期的內(nèi)涵,對影響配送周期的因素進行了分析,為下面構建配送周期模型奠定了理論基礎。然后,選擇運輸業(yè)務作為企業(yè)的核心競爭力、集中型配送服務網(wǎng)絡為例,在一定的假設條件與約束條件下,構建了以配送周期最短為目標函數(shù)的物流配送周期模型。最后,選取了陜西某冷藏物流運輸公司在西安市同一區(qū)的10個客戶為例,在確定的配送服務網(wǎng)絡下,運用節(jié)約里程法求解出最優(yōu)的配送方案,根據(jù)各工作間的先后順序及邏輯關系繪制出其相應的配送服務網(wǎng)絡圖,運用關鍵路線法確定出最短配送周期。
[Abstract]:In today's society, the main characteristics of global competition are demand-driven and rapid response to market opportunities, so that the growing scale of enterprises in order to cope with customer demand changes of high speed and high flexibility purposes, More and more to pursue the efficiency of their own way of operation. In the increasingly competitive market environment, logistics enterprises or distribution centers must find out its core competitiveness and its core business model, and optimize the allocation of resources owned by themselves. When making long-term strategy, more and more enterprises will bring logistics distribution into the competitive strategy of enterprises, some even regard distribution ability as an important index to measure the core competitiveness of enterprises. Time management is an important source for distribution centers to maintain market competitiveness. The essence of time competition is to shorten the time in the process of distribution of goods. Therefore, the shortening of distribution cycle can determine the scientific and efficient operation of the whole logistics distribution system. In this paper, the connotation of business outsourcing, the reasons of logistics outsourcing, the theory of logistics distribution and the theory of network diagram are expounded. On the basis of this, the key elements of logistics distribution system are discussed. Secondly, it analyzes the elements of logistics distribution service network and its classification, redefines the connotation of logistics distribution cycle, analyzes the factors that affect the distribution cycle, and lays a theoretical foundation for the following construction of distribution cycle model. Then, select transportation business as the core competitiveness of enterprises, centralized distribution service network as an example, under certain assumptions and constraints, a logistics distribution cycle model with the shortest distribution cycle as the objective function is constructed. Finally, 10 customers of a refrigerated logistics transportation company in the same district of Xi'an are selected as an example. Under the determined distribution service network, the optimal distribution scheme is solved by using the mileage saving method. The distribution service network diagram is drawn according to the sequence and logical relation of each work, and the shortest distribution period is determined by the key route method.
