【摘要】：生产线性能作为生产企业最关心的问题之一,在企业的日常生产管理中有着重要的理论和实际意义。但是生产企业通常使用一些诸如生产效率,生产线产能,在制品库存等独立的指标进行评价,同时也发现有一些目标之间本身就是一个相互影响,相互矛盾的关系,使企业对于如何正确评价生产线性能,如何平衡各指标的关系变得困难。本文从企业生产实际出发,在深入研究企业产品制造工艺和生产线特点的基础上,使用工厂物理学相关理论对生产线性能评估做了一些创新性和探索性的研究,主要内容为: 1.以工厂物理学的里特定律的基本理论为依据,建立一个以制造周期,在制品,生产产出三个维度的关系矩阵。同时根据合理的数学假设,在理论最优、理论最差、假定实际三种内部标杆评价体系的基础上对生产进行评估分析。 2.深入研究半导体制造过程的自身特点,通过收集生产线实际数据,进过数学分析的合理转化,将生产数据处理为符合模型规范的参数,并进行实际评估,并根据评估结果给出一些合乎实际的改进建议。 3.生产线性能评估系统开发。将上述评价理论,使用流程分析的方法,提出功能需求,建立E-R(关系实体图),软件运行环境设计,再通过ASP.NET建立数据库概念模型及物理模型。最后在VisualStudio2008平台和IIS Web服务器之下实现评估系统的功能。
[Abstract]:Production line performance, as one of the most concerned issues in production enterprises, has important theoretical and practical significance in the daily production management of enterprises. However, manufacturing enterprises usually use independent indicators such as production efficiency, production line capacity, in-process inventory and so on. At the same time, they also find that there are some objectives that themselves are a mutually affecting and contradictory relationship. It is difficult for enterprises to evaluate the performance of production line correctly and balance the relation of each index. On the basis of deep research on manufacturing process and production line characteristics of enterprises, this paper makes some innovative and exploratory research on the performance evaluation of production line by using relevant theories of factory physics. The main contents are as follows: 1. Based on the basic theory of Ritter's law in factory physics, a relational matrix of three dimensions, manufacturing cycle, in-process and production, is established. At the same time, according to the reasonable mathematical hypothesis, the production is evaluated and analyzed on the basis of the optimal theory, the worst theory, and the assumption of three kinds of internal benchmarking evaluation system. 2. This paper deeply studies the characteristics of semiconductor manufacturing process, through collecting the actual data of the production line, through the reasonable transformation of mathematical analysis, the production data is processed into the parameters that conform to the model specification, and the actual evaluation is carried out. According to the evaluation results, some practical suggestions for improvement are given. 3. Production line performance evaluation system development. Based on the above evaluation theory and the method of flow analysis, the functional requirements are put forward, E-R( Relational entity Diagram) and software running environment are designed, and then the conceptual model and physical model of database are established through ASP.NET. Finally, the function of evaluation system is realized under VisualStudio2008 platform and IIS Web server.
