【摘要】：产品质量安全直接维系国计民生,是社会舆论和政府关注的焦点。近几年来,为了预防和降低产品伤害事件的发生,各个国家均从不同层面开展了产品伤害监测实验和研究,政府部门不断加强产品伤害监测的事后监管。美国数据显示,近几年来的产品伤害监测工作大大降低了产品伤害事件的发生,而我国随着社会经济的快速发展,日常生活产品种类的日益丰富,产品导致的质量和安全问题日益严重,所以,我国政府已经开始高度重视产品伤害监测工作。党中央国务院印发的《质量发展纲要(2011-2020年)》中明确指出：产品伤害监测系统是我国健全公共安全体系的重要组成部分之一,应该加大力度推进产品伤害监测系统的建设。每年国家的“315”晚会披露的内容也全面展示出国家对产品质量安全问题的重视程度。因此急需建立健全产品伤害监测系统,然而开展符合中国特色的产品伤害监测系统需要完善的数据分析技术支持,本文从这个角度进行分析阐述。本文将信息分析技术,尤其是定量的综合决策方法,应用到产品伤害排序和产品质量安全风险评估中,从多角度对产品质量安全风险进行了全面客观的评价。本文具体进行了如下研究：1、通过对比欧盟及美国等发达国家完善的产品质量监测体系与监测系统,以系统性与实用性为原则,以产品伤害监测系统数据项为基础,构建了产品伤害评估指标体系,进一步将灰色关联分析方法应用到伤害事故严重程度评价。在此基础上,对产品伤害进行了聚类分析,明确的划分伤害事件级别。结果表明：该模型能较为准确的评估产品伤害程度,可为产品质量安全管理提供技术支持和科学建议。2、同时利用这套指标体系和试点医院伤害监测的时间序列数据建立风险预警模型进行实证分析,从而通过产品伤害事件的演化规律预测产品质量的变化状况,以期国家政策和相关部门采取措施降低发生质量风险。
[Abstract]:Product quality and safety directly maintain the national economy and people's livelihood, is the focus of public opinion and government.In recent years, in order to prevent and reduce the occurrence of product injury events, various countries have carried out product injury monitoring experiments and research from different levels.Data from the United States show that the monitoring of product injury in recent years has greatly reduced the occurrence of product injury events. With the rapid development of social economy, the variety of products in daily life has become increasingly rich in China.The quality and safety problems caused by products are becoming more and more serious, so our government has begun to attach great importance to product injury monitoring.In the quality Development outline 2011-2020 issued by the CPC Central Committee and the State Council, it is clearly pointed out that the product injury monitoring system is one of the important components of improving the public safety system in China, and we should strengthen the construction of the product injury monitoring system.The content of "315" party also shows the importance of product quality and safety.Therefore, it is urgent to establish and improve the product injury monitoring system. However, the development of the product injury monitoring system with Chinese characteristics needs the technical support of perfect data analysis.In this paper, the information analysis technology, especially the quantitative comprehensive decision method, is applied to product injury ranking and product quality and safety risk assessment, and a comprehensive and objective evaluation of product quality safety risk is carried out from multiple angles.By comparing the product quality monitoring system and monitoring system in developed countries such as the European Union and the United States, this paper has carried out the following specific research as follows: based on the principles of systematization and practicability, and based on the data items of the product injury monitoring system,The index system of product injury evaluation is constructed, and the grey relational analysis method is applied to evaluate the severity of injury accident.On this basis, cluster analysis of product injury is carried out, and injury event level is clearly classified.The results show that the model can accurately evaluate the degree of product injury.It can provide technical support and scientific advice for product quality and safety management. At the same time, this index system and time series data of injury monitoring in pilot hospitals can be used to establish risk early warning model for empirical analysis.The change of product quality can be forecasted by the evolution law of product injury event, so as to reduce the risk of occurrence quality by national policy and relevant departments.
