【摘要】：揀選策略與信息化程度是影響倉(cāng)庫(kù)作業(yè)效率和質(zhì)量的重要因素。合理的揀選策略與路徑設(shè)計(jì)，不僅能提高倉(cāng)庫(kù)的工作效率，而且能有效地降低物流作業(yè)成本�，F(xiàn)代信息技術(shù)在物流行業(yè)的廣泛應(yīng)用,為倉(cāng)庫(kù)管理的信息化、智能化、自動(dòng)化、標(biāo)準(zhǔn)化創(chuàng)造了良好的條件。倉(cāng)庫(kù)管理系統(tǒng)（WMS）的應(yīng)用，能夠有效地提高倉(cāng)庫(kù)管理的效率,進(jìn)一步降低倉(cāng)儲(chǔ)物流成本，改善供應(yīng)鏈的服務(wù)質(zhì)量，增強(qiáng)企業(yè)的市場(chǎng)競(jìng)爭(zhēng)力。 本文密切結(jié)合某大型重工業(yè)企業(yè)的生產(chǎn)實(shí)際，采用調(diào)查研究與數(shù)學(xué)建模分析相結(jié)合的方法，研究?jī)?yōu)化了S公司半成品庫(kù)的揀選作業(yè)流程和倉(cāng)庫(kù)管理系統(tǒng)問(wèn)題，從揀選單據(jù)優(yōu)化和揀選路徑優(yōu)化兩個(gè)方面入手，以揀選路徑總長(zhǎng)度最短為目標(biāo)函數(shù)，以揀選設(shè)備的容量限制為約束條件，對(duì)所有的揀選單進(jìn)行分批，，并采用節(jié)約式啟發(fā)算法進(jìn)行求解。揀選單據(jù)優(yōu)化完成后又依據(jù)邊際效用遞減的經(jīng)濟(jì)學(xué)原理對(duì)影響倉(cāng)庫(kù)揀選人員效能的因素進(jìn)行了分析,并提出可以提升揀選人員效能的措施。其次研究揀選路徑優(yōu)化的方向，在揀選單分批模型的基礎(chǔ)上，參照TSP模型建立路徑優(yōu)化模型，對(duì)揀選路徑進(jìn)行優(yōu)化。文章對(duì)揀選流程進(jìn)行優(yōu)化與改進(jìn)后，還對(duì)倉(cāng)庫(kù)各項(xiàng)作業(yè)流程加入WMS系統(tǒng)進(jìn)行管理控制與改善，并對(duì)比了引入WMS系統(tǒng)后為倉(cāng)庫(kù)帶來(lái)的顯著績(jī)效提高。
[Abstract]:The selection strategy and the degree of information are the important factors that affect the efficiency and quality of warehouse operation. Reasonable picking strategy and path design can not only improve the working efficiency of warehouse, but also improve the working efficiency of warehouse. And it can effectively reduce the cost of logistics activities. The wide application of modern information technology in the logistics industry has created a good condition for the information, intelligence, automation and standardization of warehouse management. It can effectively improve the efficiency of warehouse management, further reduce the cost of warehouse logistics, improve the service quality of supply chain, and enhance the market competitiveness of enterprises. Based on the production practice of a large heavy industry enterprise and the method of combining investigation and mathematical modeling and analysis, this paper studies and optimizes the sorting process and warehouse management system of semi-finished product warehouse in S Company. Starting with the optimization of picking documents and path, taking the shortest path length as the objective function and the capacity limitation of the picking equipment as the constraint condition, all the picking orders are divided into batches. After the optimization of picking documents is completed, the factors that affect the efficiency of warehouse pickers are analyzed according to the economic principle of diminishing marginal utility. The paper also puts forward some measures to improve the efficiency of picking workers. Secondly, the direction of path selection optimization is studied, and the path optimization model is established by referring to TSP model on the basis of picking single batch model. After the optimization and improvement of the picking process, the management control and improvement of the warehouse operation process by adding the WMS system are carried out, and the remarkable performance of the warehouse after the introduction of the WMS system is compared.
