食品安全微生物风险分析的原则和应用 总被引:8,自引:0,他引:8
食品安全风险分析是当前国际社会普遍应用的食品安全宏观管理模式,也是进行食品安全宏观管理的有效工具。风险分析最早应用于环境危害控制领域。1991年,FAO/WHO食品标准、化学品及贸易会议通过了“在食品安全评价时继续以适当的科学原则为基础并进行风险评估”的决议,第19届CAC会议采纳了此决议。1995、1997、1999,FAO/WHO三次召开了主题为“风险 相似文献

The purpose of this paper is to select the appropriate maintenance strategies for each failure mode of functionally significant item of conventional milling machine. In order to describe the criticality analysis of conventional milling machine, this paper presents a study on reliability‐centered maintenance with fuzzy logic and its comparison with conventional method. On the basis of fuzzy logic, failure mode and effect analysis is introduced integrating with fuzzy linguistic scale method. After that, weighted Euclidean distance formula and centroid defuzzification is used for calculating risk priority number. The results indicate that based on risk priority number, value criticality ranking was decided, and appropriate maintenance strategies were suggested for each failure mode. It also reflects that a more accurate ranking can be performed by the application of fuzzy logic using linguistic rule to failure mode and effect analysis.

A nation automatically becomes strong if it has self-sufficiency to fulfil its defence requirements. India is moving in the direction to attain self-reliance in the defence sector. The aim of this paper is to analyse the critical issues faced in outsourcing by an organisation in Indian Defence Sector and extend easy, quick, complete and practically implementable risk mitigation strategies for enabling better decision-making. In this research, a list of 20 risk criteria is finalised on the basis of the literature survey and expert’s opinion. Analysis in this research shows that, three criteria which can seriously affect the outsourcing are Material shortage risk, Quality Risk and On-time delivery risk. The paper employs an integrated framework which includes ‘Grey Theory, Failure Mode and Effect Analysis (FMEA) and Risk Management Matrices’ for a comprehensive risk management in the defence sector. The paper delivers a 10-point risk management action plan to counter the various problems faced during outsourcing in the defence sector, especially in the Indian context. In brief, this paper investigates the various important issues related to outsourcing, which are faced by organisations working in Indian Defence Sector and extends a practically implementable methodology to derive a practically amicable solution for the case organisation. 相似文献

Failure Mode and Effects Analysis (FMEA) is commonly used for designing maintenance routines by analysing potential failures, predicting their effect and facilitating preventive action. It is used to make decisions on operational and capital expenditure. The literature has reported that despite its popularity, the FMEA method lacks transparency, repeatability and the ability to continuously improve maintenance routines. In this paper an enhancement to the FMEA method is proposed, which enables the probability of asset failure to be expressed as a function of explanatory variables, such as age, operating conditions or process measurements. The probability of failure and an estimate of the total costs can be used to determine maintenance routines. The procedure facilitates continuous improvement as the dataset builds up. The proposed method is illustrated through two datasets on failures. The first was based on an operating company exploiting a major gas field in the Netherlands. The second was retrieved from the public record and covers degradation occurrences of nuclear power plants in the United States. 相似文献

Risk evaluation is one of the important elements of international engineering project management. The risk factors of international engineering projects are systematically analyzed from multiple dimension features of the projects. The muhilayer evaluation index system for the international engineering project risk assessment is proposed and constructed, which consists of 8 I-grade indexes and 24 II-grade indexes as policy risk, market risk, resource risk, and technical scheme risk, schedule risk, funding risk, personnel risk and management risk. And then the self-evaluation and benchmarking evaluation methods are applied to evaluate the international engineering project risk, and established the corresponding mathematical models. Finally, a project evaluation example is given to illustrate the applicability and effectiveness of the mathematical models. 相似文献
