尊重

前段时间在浙江参加了某品牌的订货会,这次采访让我看到了一个负责任的品牌对代理商的尊重。在订货会上,我认识了两位长期合伙的代理商。去年以来,在他们经营的市场有一批门店续签了合同,开发商把租金上涨了一倍。之后,由于渠道成本大幅上涨,公司业绩出现了持续亏损。在坚持了一段时间后,其中一人担心亏损无法控制,认为局面已经超出了心理承受范围,于是便产生了撤资的

品书之道

正阅读、学习、思考不是一时一事的事情,是一生一世的大工程。书读的多了,眼光远了,胸怀宽了,见识增长了,情操陶冶了,人生境界就提升了"要么学习,要么死亡。"现在有很多人都以"忙"为借口不读书。读不读书不在于"忙不忙",而在于有没有读书的欲望。有了这种欲望,玩着玩着就能把书读了,读着读着还能把钱赚了。中国有很多的企业家都很会读书,很善于读书,而且把读书用于     

改革语境下的电力发展

年关又至,盘点2012年的电力工业,可用波澜不惊形容。煤价下来了,发电企业的日子宽松了一些,有了更大的空间来调整优化资产结构;新能源不景气,但毕竟比例还小;供电没像去年一样出现电荒,经济下滑,用电量增幅小了,供电企业抽空上了几个关系国计民生的大项目,为电力行业争光不少。只是到了年底,一些关于改革的窃窃私语,让改来改去改了十年的电力人心里有了一丝忐忑。

城市过江通道交通流速度和密度关系研究

为确定城市过江通道交通流特性是否符合经典的速度-密度关系模型,研究了四川泸州市沱江一桥上的过江交通流。利用视频检测技术,获取了包含高峰期、平峰期等各种交通运行状态的交通流流量、速度数据,经过数据清洗、转换后,对速度和密度数据进行了回归分析和显著性检验,并计算得到了交通流特征参数自由流速度和阻塞密度。结果显示,城市过江通道的进城方向更适宜Greenshields的线性关系模型,出城方向更适宜Underwood的指数关系模型。桥头段和桥中段交通流特征参数的差异性,表明了桥头交织段规划、设计与管理对提高过江桥梁衔接段通行能力的重要性,相关部门应合理组织进城方向下游、出城方向上游的交通流,以改善区域交通运行质量。     

复杂耦合网络交通动力学模型研究

为了准确反映网络的交通行为,提出一种基于复杂耦合网络的改进交通动力学模型。对双层结构耦合网络的信息产生和传递情况进行分析,并探讨了复杂耦合网络信息交通过程的特征,引入层间控制参数和层内控制参数分别控制不同层之间信息传递的速度和路径选择,重点考虑了层间传递信息的损耗代价情况。在所提动力学模型的基础上,研究了耦合网络中信息交通过程涌现出的统计学特征。结果表明：提出的耦合网络交通动力学模型中所有节点都能够产生和传递信息,随着层内控制参数的增大,网络交通容量出现先增大后减小的变化趋势,当层内控制参数为3.8时,耦合网络交通容量达到最大。研究结果对交通网络中的拥塞问题的缓解具有指导意义,可以通过调整控制参数来增大网络的交通容量。

Urban wireless traffic evolution: The role of new devices and the effect of policy

The emergence of new wireless technologies, such as the Internet of Things, allows digitalizing new and diverse urban activities. Thus, wireless traffic grows in volume and complexity, making prediction, investment planning, and regulation increasingly difficult. This article characterizes urban wireless traffic evolution, supporting operators to drive mobile network evolution and policymakers to increase national and local competitiveness. We propose a holistic method that widens previous research scope, including new devices and the effect of policy from multiple government levels. We provide an analytical formulation that combines existing complementary methods on traffic evolution research and diverse data sources. Results for a centric area of Helsinki during 2020–2030 indicate that daily volumes increase, albeit a surprisingly large part of the traffic continues to be generated by smartphones. Machine traffic gains importance, driven by surveillance video cameras and connected cars. While camera traffic is sensitive to law enforcement policies and data regulation, car traffic is less affected by transport electrification policy. High-priority traffic remains small, even under encouraging autonomous vehicle policies. Based on peak hour results, we suggest that 5G small cells might be needed around 2025, albeit the utilization of novel radio technology and additional mid-band spectrum could delay this need until 2029. We argue that mobile network operators inevitably need to cooperate in constructing a single, shared small cell network to mitigate the high deployment costs of massively deploying small cells. We also provide guidance to local and national policymakers for IoT-enabled competitive gains via the mitigation of five bottlenecks. For example, local monopolies for mmWave connectivity should be facilitated on space-limited urban furniture or risk an eventual capacity crunch, slowing down digitalization.

International Telecom Settlements: Gaming Incentives, Carrier Alliances and Pareto-Superior Reform

Liberalized countries that allow competition in international telecommunications favor traffic re-routing practices as arbitrage against foreign monopolists. This view is seriously incomplete. Monopolists, allied with carriers in liberalized countries, can use these practices to reduce termination payments to nonalliance carriersöthereby harming also consumers in liberalized countriesöby gaming regulations that require equal termination rates at both ends and 'proportional return' (the monopolist's traffic is allocated among carriers in proportion to their shares of traffic to its country). We also present a simple bilateral settlements reform that eliminates gaming incentives and other proportional-return distortions, yet benefits both countries.     

Determination of the research of computer-based technologies for urban traffic systems some experiences in project organisation and management

Research and development activities concerning urban traffic systems are the subject of a long-standing program at the German Federal Ministry of Research and Technology. A fairly recent field of investigation is the deployment of computer-based technologies in urban traffic situations. The German Federal Ministry of Research and Technology has sponsored a study to determine a comprehensive middle-term research-program for these technologies.
The study contained the following steps of investigation:
(1) Determining possible areas of deployment for computer-based technologies.
(2) Selecting deployment areas from those generated.
(3) For the deployment areas selected, deriving the required research activities, coordinating and consolidating them into a research program.
Because of the comprehensive nature of urban traffic the know-how and results from many and diverse scientific disciplines had to be incorporated into the study.
As the study has significant real-life consequences for the direction and funding of urban traffic research by the Federal Ministry of Research and Technology it had to be ensured that its outcomes were operational.
To arrive at an operational research program, the study required inputs from areas, in addition to the scientific disciplines:
(a) politics (traffic policies in general, research and funding strategies etc.)
(b) industries (manufacturers of vehicles, electronic parts etc.) and traffic operating authorities.
Some experiences gained in managing the project are reported in this paper. They pertain to the study described. Hopefully, they can be put to use in some other projects of comparable structure and objectives.     

Inconvenience cost of mobile communication failure: The case of South Korea

Mobile communication failure can occur when mobile traffic exceeds the manageable level. This depends on frequency bandwidth. Mobile communication failure causes inconveniences in a user's daily life that lead to social and economic damage. To address this issue, mobile telecommunications companies deploy additional bandwidths and develop new technologies, but these are costly strategies. This study applies a spike model based on a contingent valuation method (CVM) to measure the inconvenience cost resulting from mobile communication failure. The mean monthly willingness-to-pay (WTP) to avoid communication failure per user is estimated to be KRW 898.14 (USD 0.80) over a period of five years in our study. The inconvenience cost borne by the population is estimated to be KRW 2.97 trillion (USD 2.61 billion). Users experiencing greater frequency of communication failure are found to be willing to pay more to avoid the inconvenience. When excluding respondents citing zero-WTP, the mean WTP per user was calculated to be KRW 3426.41 (USD 3.01). Data traffic usage and frequency at which communication failure is experienced are variables that exhibit statistically significant effects on WTP to avoid mobile communication failure. Overall, estimation results show that a price discrimination based on data traffic usage or quality can be considered by mobile telecommunications companies and regulators to address the issue of data traffic inducing mobile communication failure.
