【摘要】：随着经济的快速发展,制造行业企业间的竞争越演越烈,企业如何保持自身在行业中的竞争力一直是企业在研究的问题。本文以F企业金属加工车间为例,从精益生产的角度出发,对F企业金属加工车间布局进行介绍,以及加工车间生产工序流程进行深入分析,收集各工序现场数据、信息,发现F企业金属加工车间生产流程中存在有些工位出现工作人员的分配不均匀、物流路线过长、生产成本太高等问题。根据金属加工车间改善前生产现状及生产存在的问题,运用价值流图析方法对F企业金属加工车间生产制造流程进行详细的分析、研究。对整个生产过程的增值时间、非增值时间以及增值时间比进行计算,发现整个生产过程中增值时间比率相对较低。接着对整个车间的进一步分析,运用鱼骨图法、ISM分析法得知导致非增值时间增多的因素主要有本体过多、分工不合理以及机械手臂等待。结合影响非增值时间的主要因素,明确整体改进规划思路,分析改善点,以及制定相应的改进方案,确定改进目标。最后对改进方案进行实施并对改进后的效益进行分析。本文运用价值流分析的方法对F企业整个金属加工车间的生产流程进行分析,提出对生产车间工艺流程改善方案,为F企业提高生产效率,降低生产成本,减少浪费提供理论支持。
[Abstract]:With the rapid development of economy, the competition among manufacturing enterprises is becoming more and more intense.Taking the metal processing workshop of F enterprise as an example, from the angle of lean production, this paper introduces the layout of metal processing workshop in F enterprise, and analyzes the process flow of metal processing workshop in F enterprise, and collects the field data and information of each working procedure.It is found that there are some problems in the production process of metal processing workshop in F enterprise, such as uneven distribution of workers, too long logistics route, too high production cost and so on.According to the present production situation and the existing problems before the improvement of metal processing workshop, this paper makes a detailed analysis and research on the production process of metal processing workshop in F enterprise by using the method of value flow graph analysis.The ratio of value-added time, non-value-added time and value-added time ratio in the whole production process is calculated, and it is found that the ratio of value-added time in the whole production process is relatively low.Then the further analysis of the whole workshop, the fish bone map method and ISM analysis method is used to find that the main factors leading to the increase of non-value-added time are too much body, unreasonable division of labor and mechanical arm waiting.Combined with the main factors affecting the non-value-added time, this paper clarifies the overall improvement planning idea, analyzes the improvement points, and formulates the corresponding improvement plan, and determines the improvement goal.Finally, the improved scheme is implemented and the improved benefit is analyzed.In this paper, the method of value flow analysis is used to analyze the production process of the whole metal processing workshop in F enterprise, and the scheme of improving the process flow of the workshop is put forward, which can improve the production efficiency and reduce the production cost for the F enterprise.Reducing waste provides theoretical support.
