根据国家质检总局在2004年8月30日发布的GB/T19580<卓越绩效评价准则>国家标准的要求,结合五年来质量管理奖评审和企业自我评价发现的问题,我们开展了<准则>实施中的难点分析.本文介绍其中的部分内容:一、将"领导"置于过程中,而不是摆在"职位上;二、组织在制定战略的过程中必须十分重视资料和信息的输入;三、组织应致力于提供更多的顾客价值;四、组织应关注员工职业生涯发展;五、过程设计应体现增值性、敏捷性、系统性;确保绩效测量系统的一致性和敏感性. 相似文献

This paper addresses the problem of scheduling cascaded ‘blocked out’ continuous processing units separated by finite capacity
storage tanks. The raw materials for the product lines arrive simultaneously on the input side of the first unit. But every
unit can process only one product line at a time, thus giving rise to the possibility of spillage of raw material due to limited
storage capacity. The need to process multiple product lines and the added constraint of multiple intermediate upliftment
dates aggravate the problem. This problem is quite common in petrochemical industry. The paper provides a MINLP (Mixed Integer
Non-Linear Programming) formulation of the problem. However, for any realistic scheduling horizon, the size of the problem
is too large to be solved by standard packages. We have proposed a depth first branch and bound algorithm, guided by heuristics,
to help planners in tackling the problem. The suggested algorithm could output near optimal solutions for scheduling horizons
of 30 time periods when applied to real life situations involving 3 units and 3 product lines.
Preliminary version of the paper appeared in the proceedings of MISTA, 2005. 相似文献

In this paper, we examine a joint lot-sizing and process investment problem with random yield and backorders. We allow for inspection and develop stochastic models which provide the optimal inspection and lot-sizing policy as well as the optimal process investment for variance reduction. The process quality loss profile around the target is captured via a modification of the Reflected Normal loss function. We conduct numerical experiments assuming that the proportion of defectives follows a Uniform distribution while the process quality characteristic follows either a Normal or Uniform distribution. We also develop closed-form solutions that depend on at most the first two moments of any general probability distribution of defective units and which allow us to examine the nature of optimal policies. We demonstrate via numerical experiments the value of our integrated approach for jointly determining optimal inventory, inspection, and investment policies. Overall, our models and analyses provide some interesting insights into this reasonably complex inventory-quality problem and open up several avenues for future work in this area. 相似文献

本体聚合反应过程中聚甲基丙烯酸甲酯增长自由基的ESR研究 总被引:3,自引:0,他引:3
采用TM110谐振腔和φ2mm样品管,在17℃室温条件下成功地记录了MMA本体聚合反应过程中增长自由基的ESR谱。当把DMA加入到MMA和BPO中后,立即抽取0.17ml混合液到φ2mm样品管并记谱。以后每隔2分钟记谱一次,波谱从13(5+8)条线逐渐变成9(5+4)条线。我们用阻碍振荡模型和构象重叠模型作了模拟。从全部谱图看,前者似更合理些。ESR实验表明:在聚合过程前期,自由基浓度基本保持不变,但从聚合中期的某一时刻开始,浓度剧增,它正好同步地与本体聚合反应的自加速效应相对应,而且其变化规律和单体转化率相平行。最后,我们用微波功率饱和方法观测到9线谱的协同自旋跳跃所产生的卫线,证明了主导的电子自旋晶格弛豫机理来自电子一核自旋间的偶极偶合角调制。 相似文献

Management review of the quality-management system is an item in many quality standards and a requirement of the ISO 9001:2000
standard and of laboratory standards ISO 15189 and ISO 17125, and others. These reviews are conducted to ensure that the top
management is informed and involved in the quality-management system with respect to continuing adequacy and effectiveness,
and opportunities for improvement of the system. The management review is a process that should be conducted and audited utilizing
the process approach. A process approach is defined as “An activity using resources and managed in order to enable the transformation
of inputs into outputs” (ISO 9001:2000). All identified main processes in the quality system should be monitored through data
collection by appropriate methods, assuring that data are valid, representative, and adequate. For management review data
must be collected and presented in an accessible form so that processes can be evaluated according to objectives, goals, resources,
etc. On the basis of this information the laboratory management makes the necessary decisions and ensure that actions are
taken that improve the effectiveness of the quality-management system. As output from the management review process, there
should be evidence of decisions regarding: change of quality policy and objectives; plans and possible actions for improvements;
corrective actions as appropriate; increased customer satisfaction; and planning of resources needs. Identification of the
processes involved and using the process approach in the management review ensures the continual improvement of the quality
system.

研究矩阵元素为Fuzzy数的互反判断矩阵的传递性质.首先得到了判断两个Fuzzy数近似相等的等价条件,并得到了揭示Fuzzy数的核之间关系的一个充要条件.在此基础上,进一步证明了一致性互反Fuzzy判断矩阵具有传递性的两个结论.这两个结论说明:在层次分析法中,用一致性互反Fuzzy判断矩阵表示一组方案在同一目标下的两两重要性比较是符合理性决策的思维特征的. 相似文献
