摘要
随着经济的快速发展和市场动向需求,对于高质量低价格的产品需求模式越来越多,基于此,需要企业在产品生产中不断提高自身生产效率和产品质量,尤其是对家具产品来说,特别是针对那些仍然保持机械生产和人工生产相结合的系统模式,对产品的高要求体现在产品质量、生产过程可控性等方面。木门企业生产能力与其生产线的工作效率和工序间的平衡因素密切相关,本文将着重分析木门产品加工的生产能力,以引导木企业正确高效的进行加工线的平衡调度及管理需求。该研究运用SPSS统计软件对采集到的视频时间数据进行分析检验,及采用CPA(process capability analysis)过程能力管理方法进行系统的分析总结。A企业在木平面门的制作过程中,整体工艺过程能力值分布在0.97~1.00之间,表明现阶段该企业的木门生产工序的制造过程能力不足,而Cpk和Cp的值相对比较接近,证明其企业的制造能力和现阶段生产要求相吻合。以上现象表明木产品类的生产现状是需要进行分层调查以及采取应对措施改善现状。对于木门产品的过程能力分析有助于企业更系统全面科学的了解自身加工的能力,并以数学统计的方式准确指出瓶颈问题及工序间不平衡的问题,在更广泛的木产品及家居产品生产中提出切实可行的测试方法以供改良管理需要。
The current period of economic development, as well as market activity, can be characterized as the pressure on organizations by customer demand for low prices and high-quality products. Continuously increasing of these demands and requirement of market competition force each company to achieve a higher level of efficiency within all production activities. For furniture companies, more attentions are required for their products quality and controllable production processes, especially to those companies still having manual operations in their manufacturing system. Process capability, line balancing between each workstation and efficiency are important elements in wooden door manufacturing, this case study major analysis the wooden door producing ability to help the manufacture conduct and control the system. SPSS statistic test and process capability analysis are used in this research to guide the company understand and accomplish the improvement of their producing system. Recently, the value of Process Capability (Cp) is during 0.97-1.00 which indicate that the company A is lack of process ability but compare with the Process Capability Index (Cpk) value, Cp and Cpk value are close that means now their producing situation is match to their ability, manager need to consider about doing inspection and management. Actually, through this wooden door case study is good for other kind of wooden products to realize the problem and improve the process system.
