论现代工程训练体系的构架与建设

遵循高等工程教育改革发展趋势、学习认知规律以及工程训练中心自身的功能定等方面原则,形成以工程设计、工程制造、工程管理和工程创新为主要架构的网络结构训练平台。基于平台基础上的训练内容模块的设计应从纵向维度和横向维度着手,以满足不同受训对象群的需要。     

关于影像之真

在数字化技术高速发展条件下,我们同时生活真实世界与虚拟世界之中。因此,关于影像真实的判断同样是建立在这两个世界的基础之上的,而虚拟世界是以影像为原初的呈现方式的,所以,更应重视虚拟世界对我们生活方式、思维方式的影响。

A global meaning of supply chain social sustainability

Abstract

The purpose of this research is to help reduce tensions in supply chain social sustainability (SCSS) decisions by providing a common global, contextual definition of social sustainability. This exploratory study utilised an inductive structured interview method to capture SCSS concept meanings. Those interviewed are from, have lived, and worked in developed economies, emerging economies and the base of the pyramid (BOP) economies. The results present a new global baseline definition of SCSS to inform theory and practice by finding that SCSS meanings differ not only between the different levels of economic development, but also within the levels as well. Culture, community and whether basic human needs are met all weigh into perspectives of what this concept is and should entail; a broad, contingent definition is most appropriate moving forward for sustainability planning and execution. Further research with stakeholders in more countries and communities is needed to validate our proposal.     

基于学习曲线的ERP实施培训时间决策模型

通过分析ERP项目的特点,将学习曲线引入到ERP实施的研究中,基于学习曲线理论刻画企业的工作效率随项目时间变化的规律.在此基础上,将ERP项目抽象为前期的培训和后期的具体实施两个阶段,以项目实施周期和咨询成本最小为目标,建立ERP实施培训时间决策模型,通过培训时间控制并预测ERP项目的整体周期,进一步利用遗传算法对模型进行优化求解.为区分信息化基础不同的企业在项目初期工作效率的差异,在模型中加入初始工作效率这一变量,通过企业的信息化基础水平间接地测算企业的初始工作效率;结合行为导向的实证研究结果,在模型中限定培训时间的取值范围,解决多个近似解之间的取舍问题.案例研究表明,模型在实际应用中可以起到较好的优化和预测效果,能够为企业制定ERP项目计划和投资预算提供决策支持.

Quantal Risk Assessment Database: A Database for Exploring Patterns in Quantal Dose‐Response Data in Risk Assessment and its Application to Develop Priors for Bayesian Dose‐Response Analysis

Quantitative risk assessments for physical, chemical, biological, occupational, or environmental agents rely on scientific studies to support their conclusions. These studies often include relatively few observations, and, as a result, models used to characterize the risk may include large amounts of uncertainty. The motivation, development, and assessment of new methods for risk assessment is facilitated by the availability of a set of experimental studies that span a range of dose‐response patterns that are observed in practice. We describe construction of such a historical database focusing on quantal data in chemical risk assessment, and we employ this database to develop priors in Bayesian analyses. The database is assembled from a variety of existing toxicological data sources and contains 733 separate quantal dose‐response data sets. As an illustration of the database's use, prior distributions for individual model parameters in Bayesian dose‐response analysis are constructed. Results indicate that including prior information based on curated historical data in quantitative risk assessments may help stabilize eventual point estimates, producing dose‐response functions that are more stable and precisely estimated. These in turn produce potency estimates that share the same benefit. We are confident that quantitative risk analysts will find many other applications and issues to explore using this database.
