【摘要】：混流装配是现今许多制造装配企业采用的主要生产装配方式,它能够在基本不更改现有的装配手段、装配条件与装配能力等前提下,通过改变装配物料类型、装配模具大小、装配工序增减等方式,在一定时间内、在同一条装配线上装配出多种产品特性相似、但型号与数量均不相同的产品,使企业能够满足消费者的各种个性化需求,快速响应市场的变化,保证市场的占有率。本论文主要以某一电动工具公司混流装配平衡系统为对象进行相关问题改善研究,其主要内容如下:第一章主要对论文的研究背景、研究意义进行了阐述,同时分析了混流装配平衡系统中作业排序与物料配送两方面的一些国内外研究现状,最后描述本论文主要的研究内容和组织结构框架。第二章对精益思想与混流装配系统这两方面的相关理论与方法进行了描述,其中精益思想中主要涉及均衡化生产与精益物流的概念与改善方法,而混流装配系统则是作业排序与物料配送的概念与方法。第三章对B电动工具公司一厂混流装配系统的现状进行了了解与分析,先介绍一厂的布局和装配情况,再从作业排序与物料配送这两个方面进行现存问题的描述与分析。第四章针对一厂混流装配系统中作业排序方面存在的问题进行改善,先综合考虑实际客户订单与短期市场预测进行生产装配计划的制定,再应用最小生产循环(MPS)原理将装配计划进行均匀划分,确定每次循环需装配各型号产品的产量,然后又分别建立目标为生产装配均衡化和总换型时间最短的两个数学模型,综合考虑建立两者的总目标函数,以求出MPS中各型号产品的相对最优排序。最后以线5混流装配线上的三个不同型号的电动工具混流装配计划为例,进行其最优作业排序结果的计算。第五章针对一厂混流装配系统中物料配送方面存在的问题进行改善,从物料分类管理、物料配送方式、物料配送路径、物料配送时间等方面进行设置与规范化管理,将改善后的效果与原先状况进行比较。第六章对全文进行了总结,描述了本论文的主要研究工作与不足之处,对后续的研究进行展望。
[Abstract]:Assembly is the main production assembly used today many manufacturing and assembly enterprises, it can not change the basic assembly method, existing assembly condition and assembly capacity under the premise, by changing the material type, the mold assembly assembly size, assembly process or other way, in a certain period of time, on the same assembly line out a variety of products, but the type and quantity characteristics of similar products are not the same, so that enterprises can meet the individual needs of consumers, rapid response to market changes, to ensure the market share. This thesis is mainly based on the mixed model assembly balance system a power tool company as research object to improve the related problems, the main contents are as follows: the first chapter is mainly on the research background and significance are described, and analyzed the domestic and foreign research status quo of the two aspects of order and material distribution in the balance system of row assembly operations finally, the thesis describes the main research content and structure frame. The second chapter describes the related theory of the two aspects of lean and assembly system and method, the concept of lean thinking mainly involves the balance of production and lean logistics and improving method, and assembly system is the concept and method of scheduling and material delivery. In the third chapter, we understand and analyze the current situation of the mixed assembly system of B electric tools company. First we introduce the layout and assembly of a factory, then describe and analyze the existing problems from two aspects: job sequencing and material distribution. In the fourth chapter, a system of mixed model assembly plant scheduling problems to improve the first comprehensive prediction made in assembly planning considering the actual customer orders and the short-term market, using the minimum production cycle (MPS) principle of partitioning the assembly plan, determine each cycle required assembly products of various types of production, then are established respectively for the production assembly equalization and two mathematical models of the total exchange time of the shortest, considering the establishment of a general objective function of the two, in order to find out the relative optimal ordering of the product in MPS. At last, three different models of electric tools mixed flow assembly plan of the line 5 mixed flow assembly line are taken as an example to calculate the optimal operation sequencing results. The fifth chapter according to the existing material assembly system in factory distribution problems to improve the setting and standardized management from the material classification management, material delivery, material delivery path, material delivery time etc., will improve the result and the original condition for comparison. The sixth chapter summarizes the full text, describes the main research work and shortcomings of this paper, and looks forward to the follow-up research.
