档案是社会信息的一部分,是原始的、可靠的信息,因此档案越来越显现其重要作用。随着现代信息技术的发展,档案信息资源的开发、利用越来越显示出其重要性,尤其是质量认证、保密认证工作与档案工作的相互联系,说明现代信息技术的发展势必将现代化向档案领域渗透。如在ISO9000质量认证中,国军标GJB9001A-2001《质量管理体系要求》中要求对文件控制、记录控制、内部审核、不合格品控制、纠正措施、预防措施等六方面的活动编入程序文件、质量手册中,也就是说这六方面必须严格规范管理,加以控制。而文件控制、记录控制的要求、范围、内容又恰恰是科技档案中形成和归档的文件资料。因此,在我所的质量体系中档案室承担着与文件控制和记录控制有关的大量工作,成为质量认证时的一个重要查证部门。 相似文献

工业生产中讲到质量,有施工质量和产品质量之分。衡量施工质量可根据施工质量指标,如铸、锻件的废品率,成品合格率、返修率等。衡量产品质量可按产品评级标准,对符合技术标准的合格品,评定出质量等级,如一、二、三等品。用一等品率来衡量产品质量。企业质量管理的任务是,既要保证和提高产品质量,又要不断提高施工质量,把不合格品逐渐减少或 相似文献

结构系统的可靠性评估是结构设计的一个重要研究内容,而极限状态函数的建立是进行可靠性评估的基础.但是,大型结构系统的极限状态函数极为复杂,响应面法用简单的多项式进行模拟的精度较低,导致误差较大.文章提出用神经网络替代多项式来拟合复杂的极限状态函数,形成所谓的神经网络响应面.然后,基于塑性极限理论,文中提出了不依赖于失效模式的极限状态函数表达形式及采用ICP对该极限状态函数进行计算的方法.最后,依照拟合得到的神经网络响应面,给出了大型结构系统失效概率的方法.通过两个算例计算并和其它方法进行比较,表明该方法的计算精度较高,而计算时间大大降低. 相似文献

为了研究不同强度匹配对焊接接头安全性能的影响,基于"欧洲工业结构完整性评定程序(SINTAP)"提供的失效评定图FAD方法,针对不同强度匹配的10CrNi3MoV船体钢焊接接头,建立了对应的失效评定曲线。根据母材与焊缝的拉伸试验及CTOD(裂纹尖端张开位移)试验结果,对比分析了3种匹配条件下的接头安全评定结果。研究表明,对于选定的评定级别,不同强度匹配系数对FAD图形状的影响很小;焊缝强度较高时,接头对塑性失稳的抵抗能力取决于母材性能;接头韧度水平相似时,低匹配接头对塑性失稳及脆性断裂的抵抗能力均稍差,弱于等匹配与高匹配;焊缝强度稍高于母材的"等强匹配"安全裕度最大,安全性最佳。 相似文献

Procedure violations are commonly identified as an essential causal factor in maritime accidents. This also applies to the Norwegian offshore service vessel sector. This illustrates that there is a need to study compliance and non-compliance in a broad context and to explore the factors that affect the propensity to act in accordance with prevailing procedures. The aim of the present study was therefore to examine the antecedents of safety-compliant behaviour among workers on offshore service vessels operating on the Norwegian Continental Shelf. With reference to a survey of 1108 offshore service vessel workers, this was done by analysing the relationship between a set of predictor variables and a self-report measure of safety-compliant behaviour. Using binary logistic regression analysis, the present study revealed that the safety climate and the vessel workers’ age were positively related to safety compliance, whereas job experience and perceived procedure vagueness were negatively related to safety compliance. Theoretical and managerial implications are discussed. In sum, the findings indicate that shipowners, captains and other stakeholders within the offshore service vessel industry should consider a broad multi-factorial approach to increase safety compliance. 相似文献

One of the most important points in structural design of containerships is the strength of hatch corners. Formerly, hatch corners used to be assessed by combining the component induced by hull girder vertical bending and the component induced by hull girder torsion. In the design of new generation containerships without deck girders, the effect of cross deck fore-aft deflection has also become prominent.Another point is the impact of structural displacement on the deck fittings. About new generation ships, large fore-aft deflection of cross decks raised the new problem of interference of hatch covers, lashing bridges and other deck fittings.To cope with such problems, comprehensive analysis has been carried out during the design stage of a Post-Panamax containership. In parallel with this analysis, on-board measurement had been conducted for 3 years after delivery, in order to confirm wide varieties of structural reaction of a large container ship in seaways. Procedure to derive components of stress and deformations from selected measurement points was developed, and actual values were calculated based on actual measurement.From long-term prediction of each component, it was found that design assumption was in general appropriate. However, regarding the fore-aft deflection of cross deck strip, actual stack load is generally much smaller than the design value, and the resulting predicted extreme value was much smaller than design assumption. This factor should be taken into account in the design stage.Regarding the correlation between hull girder vertical bending and fore-aft deflection of cross deck strip, design assumption of full combination is too conservative. From the measurement, no explicit correlation was observed. Regarding the correlation between hull girder vertical bending and wave induced torsion, design assumption of no correlation was appropriate. From these results, new formulae to combine these three deflection modes were proposed.Whipping was observed in the measured data, indicating that more careful attention should be paid to avoid large stress concentration in deck area to enhance fatigue strength. 相似文献
