In this paper, a multi-objective model aiming to minimize both distribution cost and cargo damage cost is constructed to study the vehicle routing problem (VRP) with multi-type vehicles in the cold chain logistics system. Since VRP is an NP-hard problem, the optimal solutions cannot be obtained in a short time with exact algorithms as the scale increases. The genetic algorithms based on two decoding methods giving the priority to capacity and cargo damage are designed to solve the problem. The algorithm is applied to solve the distribution problem of H logistics company and the results obtained with two decoding methods are compared.
本文建立了以配送成本和货损成本同时最小化为目标的多目标模型,研究了冷链物流系统中多类型车辆的车辆路径问题。由于VRP是np困难问题,随着规模的增大,用精确的算法无法在短时间内得到最优解。针对这一问题,设计了基于两种解码方法的遗传算法,分别优先考虑货物容量和货物损坏。将该算法应用于H物流公司的配送问题,比较了两种解码方法的解码结果。

The success of Nongfu Spring is inseparable from its innovative and diversified advertising methods in the era of “Internet +”. Through experiments and scientific analysis of Nongfu Spring's advertising marketing, some advertising strategies for the beverage consumer market can be summarized. Firstly, enterprises should learn to use advertising psychological strategies. Secondly, when design advertising words enterprises should aim at the consumer's inner demand to give consumers hints in the streamlined statement. At the same time, combining with its own strategy, enterprises could use framing effect to set price. In addition, various enterprise can also use the advantages of Internet, and combine with the market position of their own brands to host joint activities to achieve better brand publicity.
农夫山泉的成功,与其在“互联网+”时代创新、多元化的广告方式密不可分。通过对农夫山泉广告营销的实验和科学分析,可以总结出一些针对饮料消费市场的广告策略。首先,企业要学会运用广告心理策略。其次,企业在设计广告词时,要瞄准消费者的内心需求,在流线型的语句中给予消费者暗示。同时,企业可以结合自身的战略,利用框架效应进行定价。此外,各企业还可以利用互联网的优势,结合自身品牌的市场地位,举办联合活动,达到更好的品牌宣传效果。

The study of urban and regional networks in the context of flow space is the research frontier and hotspot of urban geography at home and abroad. Foreign studies mostly use information flow and air flow as the main means of studying urban and regional networks. It is of great theoretical and practical significance to explore the study of urban and regional networks that are in line with China's economic and social development. This paper uses the measured data of Beijing-Tianjin-Hebei highway freight to fit the Beijing-Tianjin-Hebei highway freight network, and uses social network analysis method to analyze the highway freight network structure in Beijing-Tianjin-Hebei region; and uses the coupled coordination model to analyze the relationship between highway freight and industrial structure. Research shows: ➀ The main highway freight contact directions of Beijing-Tianjin-Hebei are Beijing and Tangshan. ➁ The vertical grade of highway freight flow in Beijing-Tianjin-Hebei is dominant, and geographical contact group is remarkable. ➂ The network of Beijing-Tianjin-Hebei Highway freight flow tends to industrial system.

Sharing bicycle industry has been booming recently and the bicycles have irresistibly occupied the streets and lanes. At the same time, many operational problems have also been exposed. From the perspective of the macro-control of the number of sharing bicycle, this paper uses the actual operating data of the Divvy Bikes sharing bike companies in the 2013-2017 periods in Chicago to establish a regression model for the supply and demand of sharing bicycles. This paper analyzes the factors affecting supply and demand of sharing bicycle with actual data and linear regression models to derive the regression equations for supply and demand. Then, we use this regression equation in combination with a cobweb model to describe the entire supply and demand system for sharing bicycles of a brand in Chicago. Finally, we discuss the relationship between supply and demand in different population. According to research, we explore the integration applicability of linear regression and cobweb model in sharing bicycle field. Results provide a partial basis and reference method for enterprises to decide the total number of sharing bicycles in operation management. The model is tested and remedied, and then the supply and demand are utilized to establish the cobweb model, which helps dynamically analyze the supply and demand relationship of the company's shared bicycles. Then the cobweb model leads to obtain a steady state of supply and demand, which provides a basis for the company's decision-making process from a macro perspective.
共享单车行业近年来蓬勃发展,自行车已经不可抗拒地占据了街道和车道。与此同时,许多操作问题也暴露出来。本文从共享单车数量宏观调控的角度出发,利用Divvy Bikes共享单车公司2013-2017年在芝加哥的实际运营数据,建立了共享单车供需的回归模型。本文利用实际数据和线性回归模型对影响共享单车供需的因素进行分析,推导出供需的回归方程。然后,我们将此回归方程与蛛网模型相结合,描述了芝加哥某品牌共享单车的整个供需系统。最后,讨论了不同人群的供给与需求关系。通过研究,探讨了线性回归与蛛网模型在共享单车领域的集成适用性。研究结果为企业在运营管理中确定共享单车的投放总量提供了部分依据和参考方法。对模型进行检验和修正,然后利用供需关系建立蛛网模型,动态分析公司共享单车的供需关系。然后通过蛛网模型得到一个稳定的供需状态,从宏观角度为公司的决策过程提供依据。

Research on the Interaction of Information Disclosure and Channel Selection Strategies 信息披露与渠道选择策略互动研究
Pub Date : 2019-07-01 DOI: 10.1109/ICSSSM.2019.8887729

In this paper, we use a game-theoretic approach to investigate quality disclosure strategies for a dual channel manufacturer facing a potential market entry. We develop a dual-channel supply chain model consisting of an incumbent manufacturer(F1), an incursive manufacturer(F2) and a retailer. In the first stage, F1 decides whether to disclose its quality information and F2 decides whether to sell products through a retailer. In the next stage, manufacturers decide the selling prices, or they decide the wholesale prices and the retailer decides the selling prices. We derive the optimal disclosure strategies of the incumbent and channel selection of the entrant. We show that in equilibrium F1 will disclose the quality within the disclosure threshold which depends on product similarity and disclosure cost. We compare thresholds in three cases and find that F1 has the strongest will to disclose quality when F2 invades from the online channel. Moreover, we derive the results on how the optimal selling prices, wholesale prices, manufacturers' profits change when the product similarity changes, and generate managerial insights of the research findings.
本文运用博弈论的方法研究了面对潜在市场进入的双渠道制造商的质量披露策略。我们开发了一个由现有制造商(F1)、入侵制造商(F2)和零售商组成的双渠道供应链模型。在第一阶段,F1决定是否披露其质量信息,F2决定是否通过零售商销售产品。在下一阶段,制造商决定销售价格,或者他们决定批发价格,零售商决定销售价格。我们推导出了在位者的最优披露策略和进入者的渠道选择。结果表明,在均衡状态下,F1将在披露阈值内披露质量,而披露阈值取决于产品相似度和披露成本。我们比较了三种情况的阈值,发现当F2从在线渠道入侵时,F1披露质量的意愿最强。在此基础上,推导出产品相似度变化时最优销售价格、批发价格、制造商利润的变化规律,并对研究结果产生管理见解。

Short-sellers' Private Information Research: Based on the Perspective of Earnings Announcement 卖空者的私人信息研究:基于盈余公告的视角
Pub Date : 2019-07-01 DOI: 10.1109/ICSSSM.2019.8887757
Yan Zhou, H. Ding, Jia Hao
This paper selects relevant quarterly date from September 2013 to June 2016, and analyzes the relationship between short-seller's information and earning announcement. The results shows that short-selling activities increased significantly before negative earnings announcement, and there is a statistically significant negative correlation between them and post announcement stock returns. According to the empirical results and theoretical analysis, this paper argues that China's short-sellers are informed traders having negative private information, mainly conducting short-selling activity based on them, which makes negative information quickly enter the stock price, thus improving the pricing efficiency of stock.
本文选取2013年9月至2016年6月的相关季度日期,分析卖空者信息与盈余公告之间的关系。结果表明,在负收益公告前,卖空活动显著增加,且与负收益公告后的股票收益呈显著负相关。根据实证结果和理论分析,本文认为中国的卖空者是拥有负面私人信息的知情交易者,主要根据这些信息进行卖空活动,这使得负面信息快速进入股票价格,从而提高了股票的定价效率。

Pricing Strategies with Buy-Online-and-Pickup-in-Store 网上购买和实体取货的定价策略
Pub Date : 2019-07-01 DOI: 10.1109/ICSSSM.2019.8887663

Buy online and pick up in store (BOPS) is recently adopted by many retailers to attract customers to the store. We study the impact of this strategy on prices and profits of retailers. We build a model based on a Hotelling line where a retailer manages both the store and online channel in the presence of customers' strategic shopping behavior. We use customers' expectation utility to classify their choices. After BOPS is implemented, customers may choose to buy online directly, buy in the store directly or buy online pickup in store. For customers is uncertain whether the product is a good match, a part of customers who buy online directly will return it. When customers return the product, there is a loss to the retailer. We prove that BOPS can help the retailer gain higher profits under certain conditions. Then a revenue-sharing mechanism is proposed to allocate profits of the decentralized channels with BOPS. Besides, the loss of product returns may be reduced after the coordination is achieved. In a word, BOPS is a good way for retailers to draw customers to the store and make more profits. Even in a decentralized retail system where store and online channels are managed separately, a revenue-sharing mechanism can be designed to share the revenue across channels to mitigate channel conflicts and increase the profit of the whole supply chain.
最近,许多零售商采用了“网上购物,到店提货”(BOPS)来吸引顾客到店。我们研究了这一策略对零售商价格和利润的影响。我们建立了一个基于Hotelling线的模型,在这个模型中,零售商同时管理实体店和在线渠道,同时考虑到顾客的战略购物行为。我们使用客户的期望效用来对他们的选择进行分类。BOPS实施后,客户可以选择网上直接购买、到店直接购买或到店在线提货。对于不确定产品是否匹配的顾客,一部分直接在网上购买的顾客会退货。当顾客退货时,零售商就蒙受了损失。我们证明了在一定条件下,BOPS可以帮助零售商获得更高的利润。在此基础上,提出了一种收益共享机制来实现分散渠道的利润分配。此外,协调后的产品退货损失可能会减少。总之,BOPS是一个很好的方式,为零售商吸引顾客到商店,赚取更多的利润。即使在分散的零售系统中,在实体店和线上渠道分开管理的情况下,也可以设计一种收益共享机制,实现跨渠道的收益共享,以减轻渠道冲突,增加整个供应链的利润。

The assets pricing is one of the hot topics which are a debate zone of financial markets in emerging economies, and the appropriate pricing model has always been a focus of attention. The investment, market and profitability premium influence the portfolio return with alternative three factor model. This study conduct to the equity returns of Pakistan's companies. We are using half-yearly data for 2002- 2014 of one hundred non-financial listed firms at KSE. We do a regression analysis to investigate the impact of three factors (IP, MP and PP) on equity return. Finally, we do investigation and the investment and profitability premiums have a positive and significant impact on portfolio returns. The study also exposes that the alternative three factor model is an appropriate model aimed at the valuation of equities. The CNZ alternative Three Factor Model clarifies 60% −73% the portfolio returns and its explanatory power assortments. Therefore, investors, fund managers and decision makers should be account carefully for investments and profitability factors in their decisions regarding investment, financing and valuation.
资产定价是新兴经济体金融市场的热门话题之一,合理的资产定价模型一直是人们关注的焦点。采用可选三因素模型分析了投资、市场和盈利溢价对组合收益的影响。本研究针对巴基斯坦公司的股权收益进行研究。我们使用的是2002- 2014年KSE 100家非金融上市公司的半年数据。我们做了回归分析,探讨三个因素(IP, MP和PP)对股权回报的影响。最后,我们进行了调查,发现投资溢价和盈利溢价对投资组合收益有显著的正向影响。研究还表明,替代三因素模型是一种适用于股票估值的模型。CNZ替代三因素模型澄清了60% ~ 73%的投资组合收益及其解释能力分类。因此,投资者、基金经理和决策者在进行投资、融资和估值决策时,应仔细考虑投资和盈利因素。

With the frequent occurrence of financing platform problems, the supervision of financing platform is imminent. This paper chooses the evolutionary game method and considers the game model composed of government and financing platform. The research finds that the decision-making of government and financing platform affects each other, but it is difficult to control the risk of platform only depending on the constraints of platform itself. To some extent, the government's supervision of the platform can reduce the risks caused by platform auditing.

随着融资平台问题的频繁发生,对融资平台的监管迫在眉睫。本文选择演化博弈方法,考虑由政府和融资平台组成的博弈模型。研究发现,政府和融资平台的决策是相互影响的,但仅依靠平台自身的约束很难控制平台的风险。在一定程度上,政府对平台的监管可以降低平台审计带来的风险。这个电子文档是一个“活的”模板,它已经在样式表中定义了论文的组成部分[标题,正文,标题等]。

Open education data is one of the important measures to ensure education equity and promote lifelong learning. The UK government's practice of open education data is at the forefront of the world, which can be used as reference for China's implementation of the “Education Informatization 2.0 Action Plan.”. This paper introduces the UK government's open education data by means of network survey, literature analysis and comparative analysis, including concept definition, type distribution and typical application. The development of open education data in the UK has been quite in-depth and extensive, and has achieved practical results. China has a big gap in terms of open scope, data quality, data standard, development and application, and should refer to and learn from international advanced experience and practices.
开放教育数据是保障教育公平、促进终身学习的重要措施之一。英国政府开放教育数据的实践走在世界前列,可为中国实施“教育信息化2.0行动计划”提供借鉴。本文通过网络调查、文献分析、比较分析等方法,介绍了英国政府的开放教育数据,包括概念定义、类型分布和典型应用。英国开放教育数据的开发已经相当深入和广泛,并取得了实际成果。中国在开放范围、数据质量、数据标准、数据开发和应用等方面都存在较大差距,应借鉴和学习国际先进经验和做法。
