基于多智能体的公交线网动态优化系统阐述

随着我国城市化建设不断加快,道路交通拥堵问题也日益严重。为解决城市交通问题,国家加大了城市公共交通发展力度。城市公交的快速发展虽在一定程度上缓解了交通压力,但也带来了多线路公交车运行区间重叠等问题。多线路公交车运行区间重叠易造成交通资源的浪费,也会使车辆碰撞等安全事故的发生几率上升。因此,在加大力度发展城市公共交通的同时,还需要寻求科学合理的公交线路调度方法,通过对相关技术手段与科技产品的运用提高公交车到站的准点率,有效降低重叠运行区间车辆串车率,为市民的出行提供方便。论文基于相关的理论、技术与经验提出一种基于多智能体的公交线网动态优化系统,对系统的原理、构成、功能等进行分析论述,以供参考。     

Examining the effects of robotic service on brand experience: the moderating role of hotel segment

This research investigates the effects of robotic service on guest evaluations of hotel brand experience, and examines the moderating effects of hotel segment via a 2 (service delivery video: human or robot) x 3 (hotel segment: budget, midscale, or luxury) between-subjects experimental design. The findings suggest higher levels of sensory and intellectual experience from robotic service but lower levels of affective experience. For behavioral experience, robotic service influenced a higher rating for midscale and budget hotels, but not for a luxury hotel. Overall, robotic service may not necessarily enhance brand experience as influenced by the moderating role of hotel segment.     

On the equivalence between the overlapping-generations model and cyclical general-equilibrium models

We show that equilibrium cycles in an overlapping-generations model are equivalent to asymmetric equilibria in a general-equilibrium model. We use this equivalence to find equilibrium cycles in the overlapping-generations model with two and three generations, respectively. For the example with two generations we show that for certain parameter values cycles of all periods occur.     

Optimal public policy with endogenous mortality

We analyze the welfare‐maximizing policy mix between explicit and implicit taxation, where the probability of survival of the young agents depends upon the share of government expenditure on health, education and infrastructure. We show that increases in the survival probability lead to an increase in the reliance on seigniorage as a welfare maximizing outcome. However, the seigniorage tax base must be large enough for the benevolent planner to use the inflation tax.     

供应商战略性细分管理研究

供应商对企业经营绩效具有重要作用。供应商管理历来是企业管理的重要组成部分。目前,结合企业实践对供应商管理的研究比较少。借鉴营销管理中的市场细分理论,本文提出从战略角度对供应商进行细分,并针对不同的细分供应商,应用不同的管理方式进行管理,以达到企业绩效最优。     

Intergenerational Altruism and the Environment

We construct an overlapping generations model of pollution externality in which individuals are altruistically linked to their offspring as in Barro (1974). It is shown that steady-state consumption may be a decreasing function of the intergenerational degree of altruism. Despite individuals' altruism, the competitive equilibrium is not optimal. We thus study the social optimum and show that it can be decentralized.

Multidimensional Competition and Corporate Disclosure

In this paper, we argue that the influence product market competition exerts on disclosure is defined by the combined effect of the incentives and disincentives to disclose raised by the multiple competition dimensions. We distinguish between firm‐ and industry‐level competition measures, and we hypothesize that the former raises agency and proprietary costs, whereas the latter creates incentives to disclose either to fulfil the owners’ need for information to monitor managers or to deter the entrance of new competitors in the industry. Our research design allows for non‐monotonic relationships between competition and disclosure as well as for interactions between competition dimensions. Using a sample of US manufacturing companies, we gather evidence that is consistent with our hypotheses. First, we find an inverted U‐shape relationship between corporate disclosure and a firm's abnormal profitability, which is suggestive of firms being reluctant to disclose when they are underperforming (outperforming) their rivals because of the fear of unveiling agency conflicts (raising proprietary costs). Second, we observe a U‐shape relationship between corporate disclosure and industry profitability, although this U design evolves to approximate a rising function as the protection provided by entry barriers increases.     

"三言二拍"中士、商互渗现象解读

"三言二拍"这部作品,在中国古代文学史上首次以大量的篇幅肯定了商人的经商活动,从多个层面展现了士与商,塑造了中国文学史上具有新特点的士人形象和商人形象,打破了古代文学在对士、商形象塑造上"脸谱化"的做法,给人耳目一新的感觉.无论是小说中所宣扬的崭新的价值观念,还是在新时期对商人形象的重塑,都实现了对传统文本的超越,具有鲜明的时代特征.

分部报告的会计难点分析

风险报酬法与管理法各有优缺点,我国应以行业或地区为标准,并结合内部组织制度和内部报告制度确定。报告分部一般可采用国际上10%和75%的标准,结合我国国情还应作进一步的考察。在披露内容上,注意分部收入和分部费用中一些非常项目和不能合理分摊的项目不宜进入分部报告,注意选择适当的分部报告方式。
