ERP在制造企业管理中应用的回顾与思考

本文主要讨论ERP在制造业企业管理中的应用成败及产生原因。首先对制造业ERP应用情况进行了回顾,指出ERP实施成功率低的原因主要在于ERP软件、企业自身及应用环境等方面。接着对ERP实施现状进行了思考,提出了改变这一局面的相关措施。如企业自身应加强基础建设、进行业务流程重组、重视ERP咨询、慎重选择软件供应商等。

Inconspicuous anchoring effects generated by false information

The impact of false information on numerical judgments was examined on young normal subjects by an event-related potential （ERP） experiment. To imitate the judgments in real world, we ensured the subjects acknowledged of the target task. The behavioral results found that both uncertain information and false information assimilated the final estimates： higher after higher anchors and lower after lower anchors; and false information caused a weaker anchoring bias than uncertain information. ERP results provided further electro- physiological evidence for the mechanism of anchoring. In the early phrase, it was an accessibility-dominated process in which two kinds of anchors elicited an N300 component related to the accessibility of anchors propositions. The knowledge relevant to targets joined the process in the late phrase, which caused a larger amplitude of late positive component （LPC） for implausible lower anchors than that for plausible higher anchors. Source analysis showed that medial frontal gyrus, whose activity was suggested to signal the need of adjust- ment, was more reliable to explain the LPC elicited by implausible lower anchors. Therefore, we suggest that accessibility is facilitated when the external anchor is consistent with the world knowledge, and adjustment is initiated when the external anchor is inconsistent.     

Mining Sensor Data in Cyber-Physical Systems

A Cyber-Physical System （CPS） integrates physical devices （i.e.,sensors） with cyber （i.e.,informational） components to form a context sensitive system that responds intelligently to dynamic changes in real-world situations.Such a system has wide applications in the scenarios of traffic control,battlefield surveillance,environmental monitoring,and so on.A core element of CPS is the collection and assessment of information from noisy,dynamic,and uncertain physical environments integrated with many types of cyber-space resources.The potential of this integration is unbounded.To achieve this potential the raw data acquired from the physical world must be transformed into useable knowledge in real-time.Therefore,CPS brings a new dimension to knowledge discovery because of the emerging synergism of the physical and the cyber.The various properties of the physical world must be addressed in information management and knowledge discovery.This paper discusses the problems of mining sensor data in CPS：With a large number of wireless sensors deployed in a designated area,the task is real time detection of intruders that enter the area based on noisy sensor data.The framework of IntruMine is introduced to discover intruders from untrustworthy sensor data.IntruMine first analyzes the trustworthiness of sensor data,then detects the intruders＇ locations,and verifies the detections based on a graph model of the relationships between sensors and intruders.

顿悟中的蔡格尼克效应: 左右脑在解题失败与提示信息加工时的活动差异

蔡格尼克效应的存在说明人们对于那些未能完成的任务的记忆保持会更好, 而利用单侧视野呈现技术对顿悟的研究也表明: 人们在问题求解失败后, 如提示信息出现较晚, 则输入右脑的提示信息会比输入左脑的提示信息更能促成顿悟, 提示右脑在未解决问题的保持以及对相关提示信息的处理中发挥重要作用. 为了进一步验证上述结果, 本研究利用汉字组块破解任务和事件相关诱发电位(ERP)技术, 研究和比较了大脑左右两半球在问题求解失败以及关键提示信息呈现两个阶段的活动状况. 结果发现, 问题求解失败在右半球激发了更大的P150成分, 而成功的问题解决却表现出相反的趋势; 在提示信息呈现阶段对于P2成分波幅在问题类型(是否成功解决)和偏侧化的交互作用的分析表明, 左半球不受问题类型的影响, 而右半球的活动则是由不同的问题类型来调控的. 上述结果验证了先前的推测, 提示问题求解失败会引起右半球对相关问题信息的保持增强, 并最终导致右半球对相关提示信息更加敏感.
