【摘要】：随着企业对“第三利润源泉”物流成本的重视,全球范围内的制造业都将工厂物流作为重点关注的对象。工厂物流是指物料或产品按照规定的工艺流程,以在制品的形式,经过运输、装卸、加工、储存等作业流程的生产全过程,即始终体现着物料或产品实物形态的流通过程。在这个过程中,物流系统将整个生产流通的各环节进行有机整合,而工厂设施布局是整个物流系统纽带的关键环节,合理的设施规划与布局有利于提高生产力,降低物流成本。本文以K公司A工厂的多层厂房为研究对象,运用工业工程的流程程序分析和物流路线分析,详细分析了A工厂现有设备布局存在的问题。诸如工艺过程繁琐导致物料搬运路线复杂、部分作业单元和部分生产设施设备的布置不科学,带来上下货运电梯过多的停滞等待等。针对这些问题运用改进的SLP法,对现有设施布局进行优化和改善。结合该工厂的实际情况,以物流为主的单元重点进行物流分析,采用日搬运量与作业单位间的距离乘积计算物流量。生产服务部门不同于生产单元,进行定性的密切关系性分析。综合考虑作业单位间的相关性后,根据现有厂房布局的限制条件和修正因素,进行区域的重新分配和调整,得出两套备选方案,所涉及的评价及参考基准,主要由该工厂厂长、科长及相关生产线组长讨论后进行评判。对备选方案建立目标函数模型,最终选出最优布置方案。通过新旧方案的系统流量矩和对比,论证了新方案的科学性。不同于新建工厂的布置设计,本文主要目的是通过对旧厂房设施布局的改善,能够有效节约该工厂内部的物料搬运成本,解决生产过程中由于设施布局不合理带来的各种瓶颈。
[Abstract]:With the attention of enterprises to the logistics cost of "the third profit source", factory logistics is regarded as the focus in the global manufacturing industry. Factory logistics refers to the whole process of production of materials or products in the form of in-process, transportation, loading, unloading, processing and storage according to the prescribed technological process, that is, the circulation process of material or product physical form is always reflected. In this process, the logistics system organically integrates the whole production and circulation links, and the factory facility layout is the key link of the whole logistics system. Reasonable facility planning and layout is conducive to improving productivity and reducing logistics costs. In this paper, taking the multi-storey factory building of factory A of K Company as the research object, using the process program analysis and logistics route analysis of industrial engineering, the problems existing in the layout of the existing equipment in factory A are analyzed in detail. For example, the complicated process leads to the complexity of the material handling route, the unscientific arrangement of some operation units and some production facilities, and the excessive stagnation and waiting of the upper and lower freight elevators. To solve these problems, the improved SLP method is used to optimize and improve the layout of existing facilities. Combined with the actual situation of the factory, the logistics analysis is focused on the unit with the main logistics, and the product of the distance between the daily handling quantity and the operating unit is used to calculate the material flow. The production service department is different from the production unit, carries on the qualitative close relation analysis. Taking into account the relevance of the operation units, according to the constraints and correction factors of the layout of the existing factory buildings, the regional redistribution and adjustment are carried out, and two sets of options are obtained. The evaluation and reference criteria involved are mainly by the factory director. The section chief and the related production line leader discuss and judge. The objective function model is established for the alternative scheme, and the optimal layout scheme is finally selected. The scientific nature of the new scheme is demonstrated by comparing the system flow moments of the new and the old schemes. Different from the layout design of the new factory, the main purpose of this paper is to improve the layout of the old plant facilities, which can effectively save the material handling cost inside the factory and solve the various bottlenecks caused by the unreasonable layout of the facilities in the production process.
