【摘要】:在市場競爭日趨激烈和先進的制造、管理技術(shù)不斷應(yīng)用的經(jīng)濟背景下,如何降低企業(yè)的運營成本和風(fēng)險,提高生產(chǎn)效率和經(jīng)濟效益,是企業(yè)最關(guān)注的問題。隨著訂單式生產(chǎn)模式和客戶多樣性需求的不斷增多,企業(yè)應(yīng)對多變的市場能力就顯得更加重要。當(dāng)一個企業(yè)生產(chǎn)的產(chǎn)品品種增多,而它的生產(chǎn)能力卻跟不上這種發(fā)展時,是引進新設(shè)備,增加生產(chǎn)能力,還是優(yōu)化現(xiàn)有的生產(chǎn)資源,提高資源利用率,或是將一部分生產(chǎn)外包出去,降低企業(yè)的生產(chǎn)壓力。這需要企業(yè)對時間、成本、風(fēng)險、效益等因素權(quán)衡并綜合考慮做出決策。 文中就A公司兩個新項目的增加,對當(dāng)前生產(chǎn)能力不足的情況進行深入了解,提出了將兩個新項目Z5和Z6的生產(chǎn)任務(wù),按照產(chǎn)品的需求量和裝配流程相似性分別分配到現(xiàn)有的5條座椅裝配線中,這樣既可以減少建立新座椅裝配線的成本,降低企業(yè)風(fēng)險,又可以重新設(shè)計和優(yōu)化現(xiàn)有的座椅裝配線。對于新項目加入后新的座椅裝配線的設(shè)計,首先通過畫出各個項目產(chǎn)品的作業(yè)先序圖,然后運用工業(yè)工程的方法,確定每個作業(yè)要素的標(biāo)準(zhǔn)作業(yè)時間,并得出裝配線所有產(chǎn)品的混合作業(yè)先序圖。采用啟發(fā)式方法中的Hoffmann法,通過列出混合裝配線所有作業(yè)的優(yōu)先矩陣,根據(jù)計算出的座椅裝配線節(jié)拍和最少工作地數(shù),對三種座椅產(chǎn)品優(yōu)化后的所有作業(yè)單元進行作業(yè)分配。在座椅裝配線平衡優(yōu)化后,將混流線座椅的排產(chǎn)和仿真結(jié)合。通過采用最小生產(chǎn)單元循環(huán)排序法和Flexsim軟件仿真,并運用了Excel向Flexsim中導(dǎo)入數(shù)據(jù)的方法,得出了混流座椅裝配線的最優(yōu)排產(chǎn)序列。 本文的研究重點是混流裝配線的平衡優(yōu)化和排產(chǎn)問題。尤其是采用了仿真軟件和MPS循環(huán)排序相結(jié)合的方法解決了混流線的排產(chǎn)問題。實際生產(chǎn)中的平衡及排產(chǎn)問題通常要經(jīng)過生產(chǎn)線的反復(fù)試制才能決策。Flexsim仿真既避免了實際的資源和時間浪費,又為企業(yè)的混流排產(chǎn)提供了一種易于掌握而且有效的方法,也對今后的研究提供了一定的參考。
[Abstract]:In the economic background of increasingly fierce market competition and advanced manufacturing and continuous application of management technology, how to reduce the operating costs and risks of enterprises and improve production efficiency and economic benefits. With the increasing demand of order production mode and customer diversity, it is more important for enterprises to deal with the changing market ability. When the variety of products produced by an enterprise increases. But its production capacity can not keep up with this development, whether to introduce new equipment, increase production capacity, optimize existing production resources, improve resource utilization, or outsource part of production. Reduce the production pressure of the enterprise. This requires the enterprise to weigh time, cost, risk, benefit and other factors and make a comprehensive decision. In this paper, two new projects in company A are added, and the production tasks of two new projects, Z5 and Z6, are put forward. According to the demand of products and the similarity of assembly process, they are allocated to the existing 5 seat assembly lines, which can reduce the cost of establishing new seat assembly lines and reduce the risk of enterprises. It is possible to redesign and optimize the existing seat assembly line. For the design of the new seat assembly line after the addition of the new project, the first order diagram of each project product is drawn, and then the industrial engineering method is used. The standard operating time of each operation element is determined, and the sequence diagram of mixed operation of all products in assembly line is obtained. The Hoffmann method of heuristic method is adopted. By listing the priority matrix for all operations of the hybrid assembly line, calculate the seating assembly line beat and the minimum number of working places. All the work units after the optimization of the three seat products are assigned. After the seat assembly line balance optimization. This paper combines the production arrangement and simulation of mixed-line seats. By using the method of cycle sorting of minimum production unit and the simulation of Flexsim software, the method of importing data into Flexsim by Excel is used. The optimal scheduling sequence of mixed-flow seat assembly line is obtained. The emphasis of this paper is on the balance optimization and production scheduling of mixed-flow assembly line, especially the method of combining simulation software and MPS cyclic sequencing to solve the scheduling problem of mixed-flow assembly line. The scheduling problem usually needs to be trial-produced repeatedly in order to make the decision. Flexsim simulation can avoid the waste of actual resources and time. It also provides an easy to grasp and effective method for the mixed production of enterprises, and also provides a certain reference for the future research.
