Sensitivity analysis for simulation-based decision making: Application to a hospital emergency service design

An increasing concern of decision makers when dealing with system design is preparation for a wide range of potentially uncertain operating conditions. This paper provides a novel multiobjective approach for simulation-driven decision making that accounts for not only the conventional average system performance indices, but also (i) upper-tail, or extreme, values of these indices, and (ii) measures of their sensitivity to uncertainty in model parameters. The proposed approach is applied to a hospital emergency department service design case study wherein different design alternatives are compared using total time-in-system performance metric under multiple uncertain operating conditions.     

高速动车组驾驶室设计中的人机界面分析

在高速动车组驾驶室的人机关系分析与设计中,驾驶室的空间尺度关系、视野、操纵设备的分布和人机环境等因素,将直接影响列车行驶的安全、效率、舒适和健康。应用人机关系分析与研究,合理地配置驾驶室室内环境以及操作和显示设备,将有效地提高司机操作的安全性、便利性和作业效率,从而给司机提供一个方便舒适的操作空间,减少体力、心理疲劳,降低人为误操作带来的安全隐患,提高系统运行的可靠性,使人-机匹配达到最优,以保证车辆行驶的安全。     

减振器的分析与改进方案

本文对几种典型减振器做了一些分析,并根据我国主战坦克的特点提出了一种新的改进设计方案,在文中暂称为“复合作用”式减振器。它既能产生象摩擦减振器的摩擦阻尼,又能具有筒式减振器的小孔节流阻尼效果。两种阻尼的复合作用如调整适当,则对提高悬挂系统对地面情况的变化适应能力,改善车辆行驶平稳性和可靠性有很大的帮助。

From ethnographic record to system design

This paper explores the issues involved in moving from ethnographic explorations of work in context to a practical contribution to system design. It does so using the example of an interdisciplinary research project involving sociologists and computer scientists in the domain of air traffic control systems. It forms a pair with another paper (Sommerville et al., 1992) exploring these questions from the perspective of our computer science partners. We characterise ethnography as a research method, and consider the differences between undertaking it for strictly sociological or anthropological purposes by contrast with interdisciplinary and design purposes. We summarise some of our results in ethnographic explications of the work of air traffic controllers, and the sociality which it manifests. We describe the dialogues involved in rendering these observations informative for systems design, and the mutual translations implied in attempting to reconcile sociological with software engineering questions about supporting the work. We conclude by specifying some features of cooperative work which an engineering approach is in danger of overlooking; the ways, and limits, in which ethnographers can form a bridge between users and designers; and some of the conflicts of interest entrained in generating technical change.The research is funded by the UK MRC/SERC/ESRC Cognitive Science/HCI Initiative with the title Social Analysis of Control Systems for HCI Design, grant number SPG 8931598. The computer science partners are Professor Ian Sommerville, Dr Tom Rodden, Dr Pete Sawyer and Mr Richard Bentley. Thanks are due to Val King, Kjeldt Schmidt, Ian Sommerville and Tom Rodden for very helpful comments on earlier drafts of this paper.     

高温眼镜阀的创新研究与应用

转炉煤气干法除尘工艺是钢铁企业重要的节能降耗先进技术,眼镜阀是与之配套的关键设备,近年来,转炉煤气干法除尘工艺眼镜阀配置大部分采用从国外引进,费用高。文章基于TRIZ理论和方法,对转炉煤气干法除尘工艺眼镜阀进行了深入的研究,并在高温密封、液压控制、阀门自动复位等方面采用了新的方法。创新成果成功地应用于首钢京唐炼钢工程,促进了转炉煤气干法除尘工艺技术的推广。     

探析产品设计中的“绿色设计”

由于环境的恶化、自然资源的有限和过度开采,倡导环境和资源保护的绿色设计必将成为今后产品设计的主流之一;社会的可持续发展的要求预示着"绿色设计"将成为现代产品设计的重要思想。然而多数人对绿色设计真正含义并不十分明确。本文就绿色设计的具体含义作了具体的分析,并把绿色设计的内容和趋势进行了新的总结和拓展。

基于JAVAEE的工作流引擎设计的探究

工作流系统作为办公自动化软件重要组成部分,其不仅能将企业相应数据有效的和网络连接起来,同时也能将之前单独的计算机个体组成一个有机的并能自动化运行的网络系统,以便为企业提供更多信息,为企业更好的服务。就目前来看,工作流系统不仅仅在办公自动化软件中应用,在其他生产销售领域也得到了广泛应用。但是这种工作流数据在一定程度上还处于运转过程中,而新的基于JAVAEE工作流引擎程序在目前不同企业使用中,其效果还是比较可观的。本文主要从工作流管理系统概念及构成、JAVAEE技术概况、基于JAVAEE工作流引擎的设计等方面,对基于JAVAEE的工作流引擎设计进行相应探讨。     

装饰设计专业《计算机辅助设计》辅助教学网站的建设研究

装饰艺术设计专业《计算机辅助设计》课程的教学,既要能学会熟练操作各类艺术设计软件,又要有装饰制图知识、艺术设计能力和独创性思维能力。而各类辅助设计软件彼此之间缺少必要的联系和连贯性,学生很难系统掌握。因此建设本课程的辅助教学网站很有必要,使传统课堂讲授和网络教学相结合。本文同时还从网站建设思路和建设方案等方面来探讨本课程的网站辅助教学方法。
