【摘要】：隨著人們對(duì)產(chǎn)品的需求日趨多樣化和個(gè)性化,小批量多品種逐漸成為主流�？蛻魧�(duì)企業(yè)的滿意度,不僅僅只是針對(duì)產(chǎn)品質(zhì)量,還包括提供的物流配送服務(wù),要求其準(zhǔn)確、迅速的送達(dá)至客戶手中。配送中心作為供應(yīng)鏈中重要的一環(huán),其服務(wù)質(zhì)量的高低也在一定程度上影響著企業(yè)對(duì)于客戶需求的響應(yīng)度。 為了提高客戶對(duì)配送中心的服務(wù)滿意度,更好的適應(yīng)小批量多品種的要求,不少配送中心為了提高揀選效率,單獨(dú)劃分快速揀選區(qū)域,在此區(qū)域中完成所有的揀選作業(yè)�？焖賿x區(qū)將貨物集中在較小的區(qū)域內(nèi),一般采用流利式貨架等方便貨物存取的存儲(chǔ)模式。 首先,論文對(duì)現(xiàn)有的國內(nèi)外大量文獻(xiàn)以及研究成果進(jìn)行了總結(jié),介紹了配送中心以及快速揀選區(qū)的相關(guān)概念和理論知識(shí)。確定論文的研究對(duì)象是以雙快速揀選區(qū)揀選系統(tǒng)為主。 接著,提出論文的兩個(gè)主要研究問題,雙快速揀選區(qū)儲(chǔ)位空間分配以及揀選效率優(yōu)化問題。首先,在雙快速揀選區(qū)儲(chǔ)位空間分配問題中,包括了兩個(gè)基礎(chǔ)問題,一個(gè)是哪些貨物分配到哪個(gè)快速揀選區(qū)中,另一個(gè)問題是每種貨物在快速揀選區(qū)中存放數(shù)量或者體積。然后提出主要的研究思路,考慮到貨物的揀選次數(shù)、揀選數(shù)量、各自的尺寸等影響因素,基于假設(shè)條件,構(gòu)建了以揀選成本和補(bǔ)貨成本之和最小的儲(chǔ)位空間分配模型。在揀選效率優(yōu)化問題中,同樣包括了兩個(gè)基礎(chǔ)問題,一是選用訂單分批的算法,二是確定行走路線。以揀選策略為主要研究因素,介紹了訂單分批具體的實(shí)現(xiàn)過程,建立了以貨位平均揀選時(shí)間最短的揀選效率優(yōu)化模型。 最后,以某生產(chǎn)企業(yè)的配送中心為案例,分析了其揀配清單結(jié)構(gòu)、存儲(chǔ)模式、揀貨模式、補(bǔ)貨模式等。借鑒前文所提出的優(yōu)化方法,利用其真實(shí)訂單數(shù)據(jù)以及現(xiàn)場(chǎng)實(shí)測(cè)的數(shù)據(jù)等,對(duì)現(xiàn)有的雙快速揀選系統(tǒng)進(jìn)行優(yōu)化分析。證明其可行性和有效性。
[Abstract]:With the increasing diversification and individuation of people's demand for products, small batch and many varieties gradually become the mainstream. Customer satisfaction to enterprises, not only for product quality, but also for the provision of logistics distribution services. As an important part of the supply chain, the service quality of the distribution center also affects the responsiveness of the enterprise to the customer demand to a certain extent. In order to improve the service satisfaction of the distribution center and adapt to the demand of small batch and variety, many distribution centers divide the fast picking area separately in order to improve the picking efficiency. In this area, all sorting operations are completed. The fast picking area concentrates the goods in a smaller area, and generally uses a convenient storage mode such as fluency shelves. First of all, the paper summarizes a large number of domestic and foreign literature and research results. This paper introduces the concepts and theoretical knowledge of the distribution center and the fast picking area, and determines that the research object of this paper is the double fast picking area picking system. Then, two main research problems in this paper are proposed, namely, the allocation of storage space and the optimization of picking efficiency. Firstly, in the problem of storage space allocation of double-fast picking area. It includes two basic questions, one is which goods are allocated to which fast picking area, the other is the quantity or volume of each cargo stored in the fast picking area. Then the main research ideas are proposed. Considering the number of times of picking, the quantity of picking, the size of each other and other factors, based on the assumptions. A storage space allocation model based on the minimum sum of picking cost and replenishment cost is constructed. In the optimization of picking efficiency, two basic problems are also included, one is the algorithm of selecting order batches. The second is to determine the walking route. Taking the picking strategy as the main research factor, this paper introduces the concrete realization process of order batching, and establishes the optimization model of picking efficiency based on the shortest average picking time. Finally, taking the distribution center of a production enterprise as a case, this paper analyzes the structure of the sorting list, the storage mode, the picking mode, the replenishment mode and so on. Based on the real order data and the field measured data, the existing double fast picking system is optimized and analyzed. The feasibility and effectiveness of the system are proved.
