Production and changeover control policies of a class of failure prone buffered flow-shops

This article deals with a stochastic optimal control problem for a class of buffered multi-parts flow-shops manufacturing system. The involved machines are subject to random breakdowns and repairs. The flow-shop under consideration is not completely flexible and hence requires setup time and cost in order to switch the production from a part type to another, this changeover is carried on the whole line. Our objective is to find the production plan and the sequence of setups that minimise the cost function, which penalises inventories/backlogs and setups. A continuous dynamic programming formulation of the problem is presented. Then, a numerical scheme is adopted to solve the obtained optimality conditions equations for a two buffered serial machines two parts case. A complete heuristic policy, based on the numerical observations which describe the optimal policies in system states, is developed. It will be shown that the obtained policy is a combination of a KANBAN/CONWIP and a modified hedging corridor policy. Moreover, based on our observations and existent research studies extension to cover more complex flow-shops is henceforth possible. The robustness of such a policy is illustrated through sensitivity analysis.     

Camera-Related Behaviors during Video Recorded Medical Interactions

Video recording provides an objective record of the content of medical interactions. However, there is concern that cameras may be reactive measurement devices that alter what normally transpires during interactions. This study addressed potential reactivity of cameras in medical interactions. Interactions between 45 patients and 14 medical oncologists were video recorded and coded for camera-related behaviors. Eleven of 45 patients performed none of the behaviors. Among the other patients, camera-related behaviors were infrequent and, on average, constituted about 0.1% (one-tenth of one percent) of total interaction time. Behaviors occurred most often in very early stages of interactions, and when physicians were absent from the room. Seven physicians showed camera-related behaviors, comprising less than 0.1% of the time they were in the interaction. Results suggest video recording can provide nonreactive means of studying medical interactions.

功能性能分离的可信服务构件模型

为了向分布式实时嵌入式系统(DRES)的运行过程提供可信保障服务,方便上层应用程序的开发,提出了一种针对DRES的可信构件服务模型QUOCCM。该模型将系统功能实现与性能确保分离开,把应用程序的性能确保模块抽象成通用的服务确保构件,为运行于动态环境下的应用程序提供自适应的可信保障服务。该文以一个模拟实现的飞行控制系统验证了QUOCCM模型的可行性和灵活性。

基于医疗质量实时监控系统的运行病历书写质量研究

目的:研究医疗质量实时监控系统是否可以提高运行病历的书写质量?方法:对实时监控前后共四年的运行病历书写质量进行回顾性分析,监控前共抽查960份运行病历,监控后检查24 255份运行病历,从运行病历书写的及时性?完整性?内涵质量三方面进行汇总分析?结果:监控前组和监控组比较,及时性达标率由79.4%提升到85.2%(P < 0.001),完整性达标率由94.9%提升到98.2%(P < 0.001),内涵质量达标率由91.8%提升到93.6%(P = 0.114);监控后第二年(2013年)发现运行病历书写及时性?完整性?内涵质量不达标情况分别集中在危重患者病程记录不及时?入院录不完整?日常病程记录内涵质量不高等方面;运行病历书写质量受书写人员的性别?学历?职称?科室因素影响?结论:医疗质量实时监控系统的应用是提高运行病历书写及时性?完整性的有效方法,但对提高运行病历书写的内涵质量效果不明显;女性?高职称?高学历?非手术科室的医务人员运行病历书写的质量较高?
