简介：这篇论文学习产品连续地被生产的一个生产系统；其说明限制为屏蔽检查被指定。在这篇论文，我们考虑双优秀特征；与在一个更低的说明下面掉落的每个优秀特征联系的不同费用限制一个上面的说明限制的以上。由于这些不同费用，期望的全部的利润将极大地取决于过程参数，一个特别过程平均数。这篇论文为在一个单个阶段的系统与双优秀特征的考虑决定最佳进程工具开发一个基于Markovian的模型。建议模型然后通过一个数字例子被说明；敏感分析被执行验证模型。结果证明最佳为两个优秀特征处理平均数在系统的性能上有重要效果。自从处理多质量特征是极其有限的文学调查表演，建议模型，结合了Markovian途径，提供唯一的贡献给这个领域。

简介：胆囊疾病在发达国家是很普通的。复杂胆石疾病代表外科定期为被倡导的胆汁的混乱最经常。关于，胆囊炎代表普通腹的外科的干预；它能作为选任的干预或紧急情况外科被执行，在坏疽，穿孔，腹膜炎或败血的情况中。现在，laparoscopic途径被喜欢甚于开的剖腹术。全球性，众多的胆囊炎每天被执行；然而，小证据都不关于对跟随这些干预的生活(QOL)的surgical以后质量的评价存在。为了估计胆囊炎以后的QOL，事实上，高质量的照顾的文档服从于报导病人的结果满足的扩大讨论，和使用因为优秀改进被倡导几年了。然而，几乎没有很少研究，关于跟随胆囊炎的QOL结果出版；另外，许多当前的文学在以病人为中心的结果上缺乏系统的数据。然后，尽管几个工具被用来在胆囊炎以后测量QOL，困难留在选择有意义的参数以便获得可再现的数据反映手术后的QOL。这研究的目的是在QOL上为胆囊疾病考察外科的影响。这评论在QOL后面的胆囊炎上包括当前的文学的Medline搜索。大多数研究证明征兆的病人比收到选任的干预的病人从外科更获利。因此，在没有症状的外科，和病人少些获利或可以甚至在QOL有减小以前，在QOL的获得取决于一般条件。

简介：持续农业生产具有到食物供应安全的重要重要性。这研究试图在北方中国平原(NCP)并且随后在县规模调查庄稼收益反应到土壤质量的空间可变性导出关键土壤质量指示物。土壤样品从表面(020厘米)在2008引用geo、拿并且表面下(2040厘米)在整个Fengqiu县的132块地里的层，在NCP的中心定位了，为随后的土壤性质的分析。年度庄稼收益从土壤样品是镇定的一样的领域被获得。土壤质量与13个土壤性质基于一个模糊集合被评估，并且它的空间分布被集成geostatistical分析和地理信息系统(GIS)调查技术。土壤质量索引被分类进五个等级，并且他们的空间分布在县以内被印射。表面土壤质量比表面下的土壤高是大约一～二个等级。质量索引因为表面和表面下的土壤断然与年度庄稼收益被联系，建议两个的重要性。土壤有机物，全部的氮，可得到的P，和可得到的K贡献了50%联合重量到土壤质量索引并且以可持续性在区域作为土壤质量地位的关键指示物被识别。
