【摘要】：随着我国经济的快速发展和人民健康意识的不断提高,我国医疗器械市场需求增长迅猛。面对良好的发展时机,国内中小型医疗器械企业却突显出竞争力不足的现象。对此,中小型医疗器械企业亟需通过科学管理来提高效率、增加产能,以在短期内提升企业竞争力。这与工业工程的思想方法不谋而合,因此在中小型医疗器械企业中进行工业工程分析改善尤为重要。本研究以具体的中小型医疗器械T企业为研究对象,通过运用工业工程的分析方法探究导致企业效率低下的主要原因,再针对该原因运用现场管理、方法研究和生产线平衡研究来进行全面地分析与改善,并借助Witness仿真技术提出增加产量的具体方法。首先,为探究导致企业出现效率低下的原因,本研究借助鱼刺图分析法及层次分析法从人、机、料、法、环五个方面进行分析,得出生产方法为主要原因因素,为后续的改善奠定基础。其次,对生产方法涉及的三个方面做出具体改善:通过对企业组织架构进行优化设计,为改善工作的开展做好组织准备;运用目视管理和现场5S管理方法来改善生产现场,提供了良好的生产环境;对生产过程进行方法研究,结合“5W1H、ECRS”技术方法使生产的工艺程序、流程程序、生产线布局更加合理,并对改善前后的生产线平衡率进行计算对比,完成了对生产过程改善结果的评价。最后,借助Witness软件对产品的装配生产过程进行建模仿真,研究机器利用率和产量的情况,并针对机器平均利用率低和产品产量不足的问题提出了三种不同的改善方案,随后对三种方案依次仿真,评选出最优方案,达到了提高机器平均利用率和产量的目的。通过对T企业实施全面改善后,提升了企业的生产效率,增加了产品产能。
[Abstract]:With the rapid development of economy and the improvement of people's health consciousness, the market demand for medical devices in China is increasing rapidly. Facing the good development opportunity, the domestic small and medium-sized medical device enterprise actually highlights the competition ability insufficient phenomenon. In view of this, small and medium-sized medical device enterprises urgently need to improve efficiency and increase production capacity through scientific management, in order to enhance the competitiveness of enterprises in the short term. This coincides with the idea of industrial engineering, so it is very important to analyze and improve industrial engineering in small and medium-sized medical device enterprises. This research takes the concrete small and medium-sized medical device T enterprise as the research object, through the use of the industrial engineering analysis method to explore the main reason which causes the enterprise inefficiency, and then uses the field management to the reason. Methods the research and production line balance research were carried out to analyze and improve comprehensively, and the concrete method of increasing output was put forward by Witness simulation technology. First of all, in order to explore the causes of the inefficiency of enterprises, this study analyzes the factors of people, machines, materials, methods and rings with the help of fish-prick analysis and analytic hierarchy process, and draws the conclusion that the production method is the main factor. Lay the foundation for further improvement. Secondly, three aspects of production methods are improved: through the optimization of the organizational structure of the enterprise, the organization preparation for the improvement work is made; the visual management and 5S management methods are used to improve the production site. It provides a good production environment, studies the method of production process, combines "5W1H / ECRS" technology method to make the production process, process procedure and production line layout more reasonable, and calculates and compares the balance rate of production line before and after improvement. The evaluation of the improvement results of the production process has been completed. Finally, using Witness software to model and simulate the assembly production process of products, the paper studies the situation of machine utilization ratio and output, and puts forward three different improvement schemes aiming at the problem of low average machine utilization ratio and insufficient product output. Then the three schemes are simulated in turn to select the optimal scheme, which achieves the purpose of improving the average utilization ratio and output of the machine. Through the comprehensive improvement of T enterprise, the production efficiency of the enterprise is improved and the production capacity is increased.
