基于价值流图析的生产线连续流创建

针对M企业A生产线在制品积压、交付周期长等问题，通过现状价值流图分析其原因，提出在考虑改善效益大于投入成本的条件下，选择合适的自动化水平，以克服物料供应不及时、工艺特性等制约因素。从工艺流程、布局、工装等方面进行改善并绘制未来价值流图，创建生产线连续流。生产线连续流创建后，生产周期缩短了13天、搬运距离减少41m、车间面积节省约168m2、作业人数减少6人，为企业降本增效打下了坚实基础。

Creating Continuous Flow in the Production Line Based on Value Stream Mapping

Aiming at the problem of work in process backlog and long delivery period in A production line of M enterprise, this paper analyzes the reason by the situation value stream mapping and puts forward choosing the appropriate level of automation under the condition that the improvement benefit is greater than the input cost, to overcome the constraints like material supply is not timely and technological property. To improve and draw the future value stream mapping and create a continuous flow of production line through the technological process, layout, frock and other aspects of improvement. After creating continuous flow in the production line, the production cycle shortened by 13 days, transport distance reduced by 41 meters, workshop area savings of 168 square meters, the number of operators decreased by 6 people, laid a solid foundation for enterprise transformation and upgrading.
