Decision settings analysis – a tool for analysis and design of human activity systems

The paper describes a methodology to be used for analysis and design of human activity systems. The methodology is based on an analysis of the decision settings whereas most other decision analysis methodologies are analysing the process. The decision concept is analysed and discussed. A distinction between programmed and programmable as well as non-programmed and non-programmable decisions is proposed. A classification of different information types for decision making is presented. A methodology based on a systemic and systematic analysis of the information requirements of an organization is proposed. This methodology also indicates organizational discrepancies and information imbalances. The methodology focuses the settings of the decisions on all levels of organizations. The methodology can be regarded as a dynamic, learning system. The author proposes further research on the individuals decision making abilities.     

Designing and integrating composite networks for monitoring multivariate gaussian pollution fields

Networks of ambient monitoring stations are used to monitor environmental pollution fields such as those for acid rain and air pollution. Such stations provide regular measurements of pollutant concentrations. The networks are established for a variety of purposes at various times so often several stations measuring different subsets of pollutant concentrations can be found in compact geographical regions. The problem of statistically combining these disparate information sources into a single 'network' then arises. Capitalizing on the efficiencies so achieved can then lead to the secondary problem of extending this network. The subject of this paper is a set of 31 air pollution monitoring stations in southern Ontario. Each of these regularly measures a particular subset of ionic sulphate, sulphite, nitrite and ozone. However, this subset varies from station to station. For example only two stations measure all four. Some measure just one. We describe a Bayesian framework for integrating the measurements of these stations to yield a spatial predictive distribution for unmonitored sites and unmeasured concentrations at existing stations. Furthermore we show how this network can be extended by using an entropy maximization criterion. The methods assume that the multivariate response field being measured has a joint Gaussian distribution conditional on its mean and covariance function. A conjugate prior is used for these parameters, some of its hyperparameters being fitted empirically.     

试论电视教材的设计

针对当前电视教材设计中存在的重知识传授,忽视学生综合素质培养的现状,提出了以电视教材编制理论为基础,将素质教育的理念贯穿在电视教材的选题,教学设计、内容、结构、节奏、表达形式等环节的设计之中,编制素质教育需要的电视教材。     

对当前工业设计教学模式的思考

近年来,有些院校在工业设计专业的新教学计划中提出了“课程环”的构想。这样的教学模式试图把先前自成一体的课程有机地融解在数个相对的小系统中,进而形成以课题设计为中心的大系统。而过去的“三段式”教学模式则是以各门独立课程为中心的。在“三段式”教育下,有的学生几乎每门功课都优秀却做不出好设计来,更有甚者不懂设计程序而无法完成完整的设计。这种教学模式存在诸多弊端。     

对高校人文社科学报专题化运作的思考

专题化运作是一种编辑策略或编辑模式的主要体现,在常规栏目基础上通过对学术栏目的优化,提升期刊的学术品位和竞争力。有两种基本的表现形式:一是笔谈栏目,二是专题栏目。专题化运作是提高学报学术品位、创造精品力作和开拓学术研究的生长点和增长点,强化学报的学术导向,促进编辑的专业化发展的有效途径。专题化运作应注意:专题栏目定位要准确合理;建立和培育一个相对稳定的作者群;专题化运作与办好常规栏目相结合;专题栏目要密切关注现实问题。     

机械原理和设计课程设计教学探索与实践

基于产品实现过程的指导思想,结合长期参加机械原理课程设计和机械零件课程设计课指导工作实践的体会,从教学中存在的实际问题出发,进行了一系列的探索和实践。通过教学改革,学生的学习主动性、积极性增强,创新能力、实际设计能力得到了更大提高。课程设计的内容只有进行适当的改革,与工程实际结合更紧密,才能更有利于高校的人才培养。     

供应链间的竞争与协调合同设计研究

近来年,经济全球化环境中的市场竞争,越来越体现在市场中供应链之间的竞争。因此,运用News-vendor模型和博弈论方法,从行业协会角度研究竞争情况下不同供应链间在批发价合同、回购合同、收益共享合同、数量弹性合同和销售折扣合同下的协调条件,可以为通过行业协会协调增加各方利润,提供协调供应链的具体方式,从而得到协调两条供应链的合同设计方法。     

Machine learning and design of experiments with an application to product innovation in the chemical industry

Industrial statistics plays a major role in the areas of both quality management and innovation. However, existing methodologies must be integrated with the latest tools from the field of Artificial Intelligence. To this end, a background on the joint application of Design of Experiments (DOE) and Machine Learning (ML) methodologies in industrial settings is presented here, along with a case study from the chemical industry. A DOE study is used to collect data, and two ML models are applied to predict responses which performance show an advantage over the traditional modeling approach. Emphasis is placed on causal investigation and quantification of prediction uncertainty, as these are crucial for an assessment of the goodness and robustness of the models developed. Within the scope of the case study, the models learned can be implemented in a semi-automatic system that can assist practitioners who are inexperienced in data analysis in the process of new product development.
