【摘要】：以订单式生产为主的离散型制造企业,大多采取多品种、小批量混合加工的生产模式,来达到消费者对产品更加个性化、多样化的要求。在面向订单式制造企业的产品生产过程中,由于,车间物料种类繁多,数量不一,加工时间不固定等问题,因此,设计一套完整的车间物料准时配送实施方案以及智能化物料准时配送系统来保证此生产模式顺利运行。传统的拉动式配送、周期性配送均属于被动式配送,经常会出现配送不及时、不精确、不合理的现象,从而导致线边库存出现缺料或者积压现象。现有的准时制物料配送缺乏对现场实时工况的处理,没有一套完整的行之有效的实施方案。针对以上研究现状,本论文主要对以下部分做出研究：(1)物料准时配送系统中关键技术与方法研究。为了解决物料准时配送中的实时物料数据信息采集与最优配送时间窗口以及最佳配送数量的确实。本文先从车间物料准时配送中的几个关键性问题入手进行研究：配送时间点、数量、次数。运用改进时间惩罚函数公式与分析图相结合的方法求出最优配送时间点、最佳配送数量。同时,根据“一车多位”的思想规划最少的配送车次,利用高德地图的工作原理规划最优路径,接着,基于RFID的实时数据采集技术与电子看板的实数数据监控、追溯功能,避免因物料配送信息传递的滞后性,而出现物料配送的不及时、不准确、不合理现象。(2)多目标车间物料准时配送模型研究。实际生产过程中经常会出现影响物料准时配送的一些动态影响因素问题,例如：实时工况变化,紧急插单、变更,工位调整等。这种动态影响因素会带来配送成本、配送周期、配送车次等的变化,故本文设定以最短配送时间、最少配送次数和最低配送成本为多目标,建立物料准时配送多目标数学模型,并用改进混合PSO来优化此配送模型。进而以某造纸机械公司生产的二压导轨装置为实际案例,进行实例分析,并用MATLAB仿真软件对该模型进行验证分析。(3)设计一种车间物料准时配送系统实施方案。为了解决在准时制生产模式下,缺乏在物料配送信息管理的思想下建立一套行之有效的整体实施方案问题。本文特意结合物料准时配送中的一些关键技术与方法,以及物料准时配送模型,设计一套完整的车间物料准时配送系统实施方案,并以二维、三维流程图的形式更加形象的描述其运行过程。同时,针对设计的车间物料准时配送系统实施方案,运用UML.VS2005和SQL2008等建模工具构建原型系统,验证设计方案的正确性与可行性。
[Abstract]:To order the production of discrete manufacturing enterprises, mostly adopt multi varieties, small batch mixed production mode, to consumers more personalized products, diversified requirements. In order for the manufacturing enterprises in the production process, the workshop, the material variety, quantity, processing time is not fixed such problems, therefore, the design of a complete set of workshop material delivery plan and intelligent material delivery system to ensure the smooth running of pull production mode. The traditional distribution, periodical distribution and distribution are passive, often is not timely delivery, not accurate, unreasonable phenomenon, resulting in line inventory shortage or backlog. The JIT material distribution of lack of real-time status, not a complete set of effective implementation scheme for the above. The research status, this paper made a research on the following parts: (1) research on the key technology and method of material delivery system. In order to solve the problem of material delivery in real-time material data information collection and optimal delivery time window and do the best distribution quantity. This paper starts from the first workshop material delivery in several key issues study: delivery time, number of times. By using the method of improved time penalty function formula and analysis chart combining the optimal delivery time, the best delivery quantity. At the same time, according to "a car" the idea of minimum distribution planning trips, the use of high moral map of the working principle of the optimal path planning, then RFID, real data monitoring, real-time data acquisition technology and electronic Kanban based on tracing function, avoid the lag of transfer material distribution information, and the material distribution Delivery is not timely, accurate, unreasonable phenomenon. (2) research on time distribution model of multi-objective shop material. Influence of material delivery of some dynamic factors, often in the actual production process such as: real time working condition, emergency inserting, change position adjustment. The dynamic impact factors will bring the cost of delivery, delivery cycle, change the distribution of trips, so this paper set the shortest delivery time, delivery times and at least the minimum distribution cost for multi target, set up the material delivery multi-objective mathematical model, and use PSO to optimize the distribution of the improved hybrid model. Two pressure guide and production to a papermaking machinery company as the actual case, case analysis, and the model was verified by the MATLAB simulation software. (3) the implementation of a design workshop material delivery system. In order to solve the JIT production system The lack of mode, establish a set of effective overall implementation of the programme in material distribution information management ideas. This paper specially according to the material delivery of some of the key technologies and methods, as well as the material delivery model, scheme design of a complete set of workshop material delivery system, and the flow chart of 2D, 3D the more the image describe the operation process. At the same time, the implementation scheme for the design of the workshop material delivery system, a prototype system is constructed by using UML.VS2005 and SQL2008 modeling tool, the correctness and feasibility of the design are verified.
