多品种小批量环境下的家具混流生产线平衡分析与改善

随着用户对家具产品多样化和个性化的需求增多,传统的单一对象流水线生产严重阻碍了企业的发展,因此研究多品种小批量环境下的家具混流生产模式具有必要性。笔者以某家具企业为研究对象,在单一对象流水线生产现状分析的基础上,以该公司M类产品D、E、F进行混流生产线平衡分析与改善,构建产品作业顺序图,应用启发式算法求解出合理的混流生产线,最终混流生产线比原有的单一流水线效率提升在30.01%～43.96%之间,分别节约人均人工成本1.2、1.76万元/a和1.11万元/a。结果表明,混流生产线对企业成本、柔性化生产和适应市场需求等具有积极作用。

Balance Analysis and Improvement of Furniture Mixed Flow Production Line in Multi-variety Small Batch Environment

As the user demand for furniture product diversification and personalized, the traditional single object assembly line production has become a serious impediment to the development of the enterprise, so the more varieties of small batch mixed flow under the environment of furniture production pattern become necessary. With some furniture enterprises as the research objects, based on the analysis of the status quo of a single object assembly line production, the balance analysis and improvement of the mixed flow production line are carried out by D, E and F of M products of the company, the product operation sequence diagram is constructed, and reasonable mixed flow production line is solved by applying heuristic algorithm. Finally, the efficiency of mixed flow production line is improved between 30.01% and 43.96% compared with the original single production line, and the labor cost is respectively reduced by 12 000, 17 600 yuan/a and 11 100 yuan/a. The results show that the mixed flow production line has a positive effect on enterprise cost, flexible production and market demand.
