韩振东:没有硝烟的战斗——我国纤维检验公证之路

棉花是仅次于粮食的第二大农作物,也是关系国计民生的战略物资。它涉及农业和纺织两大产业,也是广大人民的生活必需品,还是出口创汇的重要商品。因此,棉花的生产、流通、加工和消费,与人民群众的生活息息相关,对国民经济的发展也有着重要影响。棉花如此重要,棉花的质量自然举足轻重,在棉花收购、加工、供应、储备、进出口以及指导棉花生产中不可缺少的公证检验环节也因此更为关键。公证检验和通常生产中的企业自检、流通中购销双方的专业检验

A quick switching sampling system by variables for controlling lot fraction nonconforming

This article develops a new sampling scheme by variables inspection, namely a quick switching sampling (QSS) system based on the process yield index for lot determination when the quality characteristic is normally distributed with two specification limits. The QSS system can provide a flexible sampling procedure by switching decision policies, normal inspection and tightened inspection. The operating characteristic curve of the proposed QSS system is derived and required to pass through two designed points, acceptable quality level and limiting quality level for satisfying risks simultaneously suffered by the producer and the consumer. The proposed sampling system’s performance is investigated and a comparison with the conventional variables single sampling (VSS) plan is also examined. The results indicate that the proposed system outperforms the VSS plan by requiring a smaller sample size for inspection while retaining the same protection. For practical purposes, the plan parameters’ tables are provided on the basis of various selected quality requirements and risks. Finally, we demonstrate the proposed sampling system using an example taken from a silicone LED lens industry.     

A new lot sentencing approach by variables inspection based on process yield

This study applies the concept of repetitive group sampling (RGS) to develop a new variables sampling plan for lot sentencing on the basis of process fraction nonconforming. The product acceptance determination problem is formulated as a nonlinear optimization problem where the objective function is to minimise the average sample number required for inspection, and the constraints are set by satisfying the acceptable quality level, limiting quality level, producer’s risk and consumer’s risk in the contract. The proposed lot sentencing approach’s behaviour is examined and discussed. The results indicate that the performance of the proposed variables RGS plan is better than that of a conventional variables single sampling plan in terms of the required sample size for inspection. Thus, the proposed approach can help the practitioner efficiently make a decision to determine whether the submitted lots should be accepted.     

Inspection Error Effects on Performance Measures of a Multistage Sampling Plan

The effects of inspection error on performance measures of single and double sampling by attributes are well known for certain combinations of sample by lot dispositions. This paper generalizes previous work on double sampling to multistage sampling. It provides expressions for the O.C. curves, average outgoing quality and average total inspection in the presence of inspection error for all combinations of sample by lot dispositions. Furthermore, the sensitivity analysis is carried out from a more general algebraic standpoint.

Variable stage-independent double sampling plan with screening for acceptance quality loss limit inspection scheme

The quality loss suggested by Taguchi has been recognised as a new quality evaluation based on variable property instead of the quality evaluation based on traditional attribute property such as the proportion of nonconforming items. Some variable sampling inspection plans in order to assure the quality have been considered. As one of those sampling inspection plans, the single sampling plan with screening (SSPS) has been constructed for acceptance quality loss limit inspection scheme. Further, the repetitive group sampling plan with screening (RGSPS) has been developed for reducing the average total inspection (ATI). Although ATI by RGSPS has successfully been reduced in comparison with ATI by SSPS, RGSPS may sometimes increase the average sampling frequency (ASF) in return for reducing ATI. In this study, the stage-independent double sampling plan with screening (SIDSPS) based on the concept of the acceptance quality loss limit inspection scheme is proposed under the consideration of the trade-off between ATI and ASF. Through some numerical comparisons about ATI and ASF in SSPS, RGSPS, and SIDSPS, the usefulness of SIDSPS proposed in this study is confirmed.     

基于过程能力指数的抽样风险研究

如果将生产过程中上一道工序的加工过程（设备）视为生产者,而紧邻的下一道工序的加工过程（设备）视为使用者,则上道工序加工的零部件在通过质量抽样检验进入下道工序的过程中．就将产生抽样风险。而由抽样风险确定的抽样方案直接关系到加工过程质量控制和检验成本控制等加工效率问题。考虑到许多大批量自动生产线的检验设备已经具备在线计算过程能力指数的能力．提出了一个基于过程能力指数的抽样风险分析方法,通过计算过程能力指数,得到相应的抽样风险．进而确定合理的抽样检验方案,从而将加工过程的重要指标——过程能力指数与抽样检验方案之间建立了联系。最后,以某汽车发动机曲轴生产线加工过程为例进行了抽样风险分析。     

论我国网络购物网站的商品质量监管责任

在我国,网络购物网站作为买卖双方的交易平台和中介,应当承担起商品质量监管的责任。这既是商业模式和政策法规的要求,也是我国当前社会信用体系不完善情况下的必然选择。我国网络购物网站采取了在线信誉机制、质量检验和质量保证、提高市场准入等措施对商品质量进行监管。但现有措施仍存在诸多待完善之处,而且网络购物网站普遍未建立起商品质量监管体系,未完全营造出健康的、追求优质商品的文化和氛围。针对这些问题,网络购物网站应尽快采取相应对策加以改善。     

Minimum Average Total Inspection Plans for Variables Sampling, Indexed by Average Outgoing Quality Limit

Dodge and Romig's 1944 volume Sampling Inspection Tables provided, among other procedures, sampling inspection plans for attributes inspection which were indexed by average outgoing quality limit. These tabulated plans guaranteed that when rejected lots are appropriately treated, the long-term average outgoing product quality would not exceed the average outgoing quality limit (AOQL) index of the plan. In addition, the plans were structured so that when the submitted quality level was at the indicated level of process average, the total amount of inspection would be minimized. In this article, plans are presented that match the AOQL, lot size, and process average parameters of the Dodge and Romig plans, but are based on variables sampling rather than attributes sampling. It is assumed that the distribution of the measured characteristic is Normal. Although measurements data are usually more difficult to obtain than attributes data and more calculation is involved in using the plans, the sample sizes are generally substantially smaller. The exception to this is for unknown standard deviation plans, higher AOQL index, and process average near the listed AOQL. It would be presumed that in present-day applications, plans involving low levels of both process average and AOQL would be most widely used.
