建立有偿代维服务模式的可行性研究

在用电高峰期,由于供电客户尤其是照明用户自身用电线路故障占有率的比例明显增大,给供电企业在抢修成本和人员配置等方面的压力也随之增大,关于客户要不要收入成本、需不需要实施有偿服务的思维碰撞也由此悄然展开。为此,就建立有偿代维服务模式的可行性进行了探讨。     

电商平台主导下的供应链推广策略研究

结合电商平台快速发展的时代背景,构建了电商平台主导、制造商跟随的两级电商供应链博弈模型,分别研究了集中决策与分散决策下的产品定价、服务水平和推广水平,分析了佣金率对最优决策和供应链成员利润的影响,并设计了"推广成本分摊"策略.结果表明:当佣金率较低时,集中决策下的产品定价和服务水平、推广水平高于分散决策下的最优决策;当...

Integrated software safety analysis method for digital I&C systems

The digitalized Instrumentation and Control (I&C) system of Nuclear power plants can provide more powerful overall operation capability, and user friendly man-machine interface. The operator can obtain more information through digital I&C system. However, while I&C system being digitalized, three issues are encountered: (1) software common-cause failure, (2) the interaction failure between operator and digital instrumentation and control system interface, and (3) the non-detectability of software failure. These failures might defeat defense echelons, and make the Diversity and Defense-in-Depth (D3) analysis be more difficult. This work developed an integrated methodology to evaluate nuclear power plant safety effect by interactions between operator and digital I&C system, and then propose improvement recommendations. This integrated methodology includes component-level software fault tree, system-level sequence-tree method and nuclear power plant computer simulation analysis. Software fault tree can clarify the software failure structure in digital I&C systems. Sequence-tree method can identify the interaction process and relationship among operator and I&C systems in each D3 echelon in a design basis event. Nuclear power plant computer simulation analysis method can further analyze the available backup facilities and allowable manual action duration for the operator when the digital I&C fail to function. Applying this methodology to evaluate the performance of digital nuclear power plant D3 design, could promote the nuclear power plant operation safety. The operator can then trust the nuclear power plant than before, when operating the highly automatic digital I&C facilities.     

Looking for errors of omission and commission or The Hunting of the Snark revisited

Since the early 1990s, considerable effort has been spent to understand what is meant by an “error of commission” (EOC), to complement the traditional notion of an “error of omission” (EOO). This paper argues that the EOO–EOC dyad, as an artefact of the PSA event tree, is insufficient for human reliability analysis (HRA) for several reasons: (1) EOO–EOC fail to distinguish between manifestation and cause; (2) EOO–EOC refer to classes of incorrect actions rather than to specific instances; (3) there is no unique way of classifying an event using EOO–EOC; (4) the set of error modes that cannot reasonably be classified as EOO is too diverse to fit into any single category of its own. Since the use of EOO–EOC leads to serious problems for HRA, an alternative is required. This can be found in the concept of error modes, which has a long history in risk analysis. A specific system for error mode prediction was tested in a simulator experiment. The analysis of the results showed that error modes could be qualitatively predicted with sufficient accuracy (68% correct) to propose this method as a way to determine how operator actions can fail in PSA-cum-HRA. Although this still leaves the thorny issue of quantification, a consistent prediction of error modes provides a better starting point for determining probabilities than the EOO–EOC dyad. It also opens a possibility for quantification methods where the influence of the common performance conditions is prior to and more important than individual failure rates.     

我国与国际食品法典委员会（CAC）食品中兽药最大残留限量标准的对比分析

对比分析我国与国际食品法典委员会(CAC)食品中兽药最大残留限量标准的异同。从标准涉及的兽药种类、具体食品种类、残留限量值三个层面逐级对比。结果表明我国标准涉及的兽药种类为217种,CAC标准为57种,二者相同的兽药种类42种;我国标准在残留具体食品动物的种类与数量上与CAC标准基本相同;我国兽药残留限量指标的总数为1035个,远远多于CAC的477个;在可比指标范围内,我国有302个残留限量指标值与CAC相同,26个残留限量指标值严于CAC,仅8个残留限量指标值宽于CAC。因此我国兽药残留限量标准中有98%的可比指标值已达到或超过CAC标准的要求。
