Date sector is a considerate sector worldwide with an estimated trade value equivalent to about 3.72 billion Saudi Riyals (SR) in 2013. Enhancing marketing efficiency of dates becomes imperative to nations that date sector has a special status in their economies and social heritage such that of the Kingdom of Saudi Arabia. This research paper is targeted to estimate the marketing efficiency of dates at different marketing channels qualitatively using a typical five level LIKERT scale and quantitatively using the Two-Stage Data Envelopment Analysis (2s DEA), to estimate the potential economic impact of improving marketing efficiency on the date marketing channels and on the national economy, and to introduce a set of policies and mechanisms that enhance the competitiveness of the Saudi dates at the local and international markets. The estimated results showed that the total market value of the Saudi dates is about 22.65 billion SR annually, and there is a great potential to improve date marketing efficiency to achieve an additional 30 per cent of value added to traders and the national economy, equivalent to about 6.88 billion SR annually. The research paper concluded with a set of policies and mechanisms to enhance the marketing efficiency and the competitiveness of the Saudi dates at the local and international markets.
枣行业是全球范围内的一个体贴的行业,2013年估计贸易价值相当于37.2亿沙特里亚尔(SR)。对于枣业在其经济和社会遗产中具有特殊地位的国家(如沙特阿拉伯王国)来说,提高枣业的营销效率势在必行。本文旨在利用典型的五层LIKERT量表对枣在不同营销渠道的营销效率进行定性评估,利用两阶段数据包络分析(2s DEA)对枣在不同营销渠道的营销效率进行定量评估,以评估提高营销效率对枣营销渠道和国民经济的潜在经济影响。并引入一系列政策和机制,以提高沙特枣在当地和国际市场上的竞争力。估计结果表明,沙特枣的总市场价值每年约为226.5亿里亚尔,提高枣的营销效率有很大的潜力,可以为贸易商和国民经济增加30%的额外价值,相当于每年约68.8亿里亚尔。研究报告最后提出了一套政策和机制,以提高沙特枣在当地和国际市场上的营销效率和竞争力。

To improve operational flexibility, throughput capacity, and responsiveness in order fulfillment operations, several distribution centers are implementing autonomous vehicle-based storage and retrieval (AVS/R) system in their high-density storage areas. In such systems, vehicles are self-powered to travel in horizontal directions (x- and y-axes), and use lifts or conveyors for vertical motion (z-axis). In this research, we propose a multi-tier queuing modeling framework for the performance analysis of such vehicle-based warehouse systems. We develop an embedded Markov chain based analysis approach to estimate the first and second moment of inter-departure times from the load-dependent station within a semi-open queuing network. The linking solution approach uses traffic process approximations to analyze the performance of sub-models corresponding to individual tiers (semi-open queues) and the vertical transfer units (open queues). These sub-models are linked to form an integrated queuing network model, which is solved using an iterative algorithm. Performance estimates such as expected transaction cycle times and resource (vehicle and vertical transfer unit) utilization are determined using this algorithm, and can be used to evaluate a variety of design configurations during the conceptualization phase.
为了提高订单履行操作的灵活性、吞吐量和响应能力,一些配送中心正在其高密度存储区域实施基于自动车辆的存储和检索(AVS/R)系统。在这种系统中,车辆在水平方向(x轴和y轴)上行驶是自供电的,在垂直方向(z轴)上使用升降机或传送带。在这项研究中,我们提出了一个多层排队建模框架,用于这种基于车辆的仓库系统的性能分析。我们开发了一种基于嵌入式马尔可夫链的分析方法来估计半开放排队网络中与负荷相关的车站的间隔时间的第一和第二时刻。链接解决方案方法使用流量过程近似来分析对应于各个层(半开放队列)和垂直传输单元(开放队列)的子模型的性能。将这些子模型连接起来,形成一个综合的排队网络模型,该模型采用迭代算法求解。使用该算法确定诸如预期事务周期时间和资源(车辆和垂直传输单元)利用率等性能估计,并可用于评估概念化阶段的各种设计配置。

Refining Advertising Regulation 完善广告规例
Pub Date : 2016-02-12 DOI: 10.2139/SSRN.2731940
D. A. Friedman
Why did the Federal Trade Commission (FTC) aggressively pursue Volkswagen’s claims about “clean-diesel” technology, while ignoring widespread practices like deceptive discount pricing? Why did the FTC offer formal guidance to industry about “native advertising,” but only casual guidance to consumers about widely-used, peer-review aggregators like Yelp! and Fandango? For decades, the FTC has only loosely employed a cost-benefit-analysis approach toward prioritizing enforcement of advertising regulation. I contend that federal regulators can best refine enforcement priorities by looking to the information economics literature for an established framework for classifying advertising claims. This Article shows that classifying advertising into search claims, experience claims, and credence claims offers a structure for more rigorous cost-benefit analysis of enforcement opportunities. Expressly incorporating this search-experience-credence claim framework into regulatory decision making and prioritization will lead to improved stewardship of FTC resources.
为什么美国联邦贸易委员会(FTC)积极追究大众汽车(Volkswagen)关于“清洁柴油”技术的主张,却对诸如欺骗性折扣定价等普遍存在的做法视而不见?为什么联邦贸易委员会对“原生广告”行业提供了正式的指导,而对消费者提供了关于Yelp等广泛使用的同行评审聚合器的非正式指导?和胡闹吗?几十年来,联邦贸易委员会只是松散地采用成本效益分析方法来优先执行广告法规。我认为,联邦监管机构可以通过查看信息经济学文献,寻找一个已建立的广告索赔分类框架,来最好地优化执法优先事项。本文表明,将广告分类为搜索声明、体验声明和信誉声明提供了一种结构,可以对执行机会进行更严格的成本效益分析。明确地将这种搜索-经验-可信度索赔框架纳入监管决策和优先排序将改善联邦贸易委员会资源的管理。

Challenges Posed by Big Data to European Data Protection Law 大数据对欧洲数据保护法的挑战
Pub Date : 2016-02-06 DOI: 10.2139/SSRN.2728624
C. Manning
The cost of storing and processing vast quantities of digital data has dropped significantly in recent years. Cloud computing services, such as those provided by Amazon, have commodified data processing so that applications that once required supercomputers are now available to anyone with an internet connection and a credit card. When the Data Protection Directive was issued in 1995 the World Wide Web as we understand it today barely existed. The scale and scope of data gathering on citizens could not have been foreseen and so the existing legal framework is challenged by the widespread collection of data on individuals as they surf the web and when they interact with businesses in the real world. Despite the confidence of the Article 29 Working Party established to monitor the effectiveness of the Directive, big data poses challenges that may prove unsurmountable for the existing legal framework.
近年来,存储和处理大量数字数据的成本大幅下降。亚马逊(Amazon)等公司提供的云计算服务使数据处理变得商品化,因此,曾经需要超级计算机才能使用的应用程序,现在只要有互联网连接和信用卡,任何人都可以使用。当1995年数据保护指令发布时,我们今天所理解的万维网几乎不存在。收集公民数据的规模和范围是无法预见的,因此,在个人上网和在现实世界中与企业互动时广泛收集个人数据,对现有的法律框架构成了挑战。尽管为监督该指令的有效性而建立的第29条工作组充满信心,但大数据带来的挑战可能对现有法律框架来说是无法克服的。

When Less is More: Data and Power in Advertising Experiments 当少即是多:广告实验中的数据和力量
Pub Date : 2015-12-29 DOI: 10.2139/ssrn.2683621
Garrett A. Johnson, Randall A. Lewis, David H. Reiley
Yahoo! Research partnered with a nationwide retailer to study the effects of online display advertising on both online and in-store purchases. We use a randomized field experiment on 3 million Yahoo! users who are also past customers of the retailer. We find statistically significant evidence that the retailer ads increase sales 3.6% relative to the control group. We show that control ads boost measurement precision by identifying and removing the half of in-campaign sales data that is unaffected by the ads. Less data gives us 31% more precision in our estimates — equivalent to increasing our sample to 5.3 million users. By contrast, we only improve precision by 5% when we include additional covariate data to reduce the residual variance in our experimental regression. The covariate-adjustment strategy disappoints despite exceptional consumer-level data including demographics, ad exposure levels, and two years’ worth of past purchase history.
雅虎Research与一家全国性的零售商合作,研究在线展示广告对在线和店内购物的影响。我们对300万雅虎用户进行了随机现场实验。同时也是零售商的老客户的用户。我们发现统计上显著的证据表明,零售商广告相对于对照组增加了3.6%的销售额。我们发现,控制广告通过识别和删除一半不受广告影响的广告内销售数据来提高测量精度。更少的数据使我们的估计精度提高了31%——相当于将样本增加到530万用户。相比之下,当我们在实验回归中加入额外的协变量数据以减少残差方差时,我们仅将精度提高了5%。协变量调整策略令人失望,尽管特殊的消费者层面的数据,包括人口统计,广告曝光水平,和过去两年的购买历史。

A Case Study on Application of DMAIC to Improve Delivery Efficiency 应用DMAIC提高配送效率的案例研究
Pub Date : 2015-12-22 DOI: 10.2139/ssrn.2706992

In this era of globalization, as competition intensifies, providing on timely delivered products and services has become a competitive advantage and a need to ensure survival. The Six Sigma’s problem solving methodology DMAIC has been one of the several techniques used by organizations to improve the deliveries of their products and services. This paper is based on an application of Six Sigma and DMAIC to improve on time deliveries within a MDF boards manufacturing organization in Sri Lanka. The paper follows the DMAIC methodology to systematically investigate the root causes of delivery failures and provide a solution to improve them. It begins with the past data analysis of the problem to find out major causes for delivery failures and after finding major causes further analysis is done to find out sub critical causes. Then reasons are analyzed for these sub causes and for these analyses Pareto charts, Brainstorming, Fish bone diagrams and verification sheets are used as tools and techniques. Finally to find out key root causes 5Y analysis is used and solutions have been proposed to overcome these issues. Product quality issues and Plant availability issues were the most problematic cause for delivery failures. Further analysis noted, Shives, Crack marks and Rough surface were the most problematic quality defects and to loss plant availability several mechanical and production related plant down time issues were caused. Metering belt broken, Doffing rolls drive chain broken and fibers leaking from gland packing at refiner 01 were the most significant causes identified as mechanical related plant down times and out feed board blockage, refiner 01 blow line blockage and forming line scalper exhaust line blockage were the most significant production related plant down time causes. This paper can be used as a guiding reference for managers and engineers to undertake specific product and process improvement projects, in their organizations, similar to the one presented in this paper. This study presents an industrial case which demonstrates how the application of Six Sigma and DMAIC can help manufacturing organizations to achieve product quality and plant availability improvements in their companies and thus contribute to their search for improvement of on time deliveries.
在这个全球化的时代,随着竞争的加剧,提供及时交付的产品和服务已经成为一种竞争优势和确保生存的需要。六西格玛的问题解决方法DMAIC已经成为组织用来改进产品和服务交付的几种技术之一。本文是基于六西格玛和DMAIC的应用,以提高在斯里兰卡的中密度纤维板制造组织的交货时间。本文采用DMAIC方法系统地研究了交付失败的根本原因,并提出了改进的解决方案。它从过去的问题数据分析开始,找出交货失败的主要原因,在找到主要原因后,进一步分析,找出次关键原因。然后分析了这些子原因的原因,并使用了帕累托图、头脑风暴、鱼骨图和验证表作为工具和技术。最后通过5Y分析找出了问题的根本原因,并提出了解决方案。产品质量问题和工厂可用性问题是导致交货失败的最主要原因。进一步分析指出,裂痕、裂纹痕迹和粗糙表面是最具问题的质量缺陷,并造成了一些机械和生产相关的工厂停机时间问题。1号精炼厂计量带断裂、落纱辊传动链断裂和压盖填料纤维泄漏是确定的与机械相关的停机时间和出料板堵塞最重要的原因,1号精炼厂吹炼线堵塞和成型线黄牛排气线堵塞是与生产相关的最重要的停机时间原因。本文可以作为管理者和工程师在他们的组织中进行类似于本文所提出的具体产品和过程改进项目的指导性参考。本研究提出了一个工业案例,展示了六西格玛和DMAIC的应用如何帮助制造组织在他们的公司中实现产品质量和工厂可用性的改进,从而有助于他们寻找准时交货的改进。

Advertising Budgets and Multinational Companies: The Nigerian Experience 广告预算与跨国公司:尼日利亚的经验
Pub Date : 2015-12-19 DOI: 10.2139/ssrn.2705744

Every business organization has an objective which is profit maximization and market growth. Manufacturers will always want to get to the final consumer and this can best be achieved through rigorous advertising processes. This study sought to find out the methods and techniques adopted by multinational companies like; the Nigeria Breweries Plc. Guinness Nigeria Plc, Nigerian Bottling Company Plc, Nestle Plc. and Cadbury Nigeria Plc, in the making of their advertising budgets on sales so as to achieve, profitability and increased market shares. In carrying out this study, literature in related areas were reviewed, questionnaire issued to the companies’ executives. The sample was 10% of the population and the technique was purposively based on positions and responsibilities. The study revealed that advertising appropriations, in the companies studied, were not made on speculations and hunches; but along the line of known conventional methods. The calculation revealed that at 5% level of confidence, x2 critical (3.8428) was less than x2 calculated (6.56) thereby upholding the hypothesis proposed, that multinational companies in Nigeria draw up their budgets through conventional budgetary methods. Based on the findings, we recommend that the most reasonable way of making appropriations is by a combination of various methods which if applied and appropriate media should be used so as to reach the actual consumers as this will reduce budget and most likely increase profitability.
每一个商业组织都有一个目标,那就是利润最大化和市场增长。制造商总是希望接触到最终消费者,这可以通过严格的广告流程来实现。本研究试图找出跨国公司采用的方法和技术,如;尼日利亚啤酒公司吉尼斯尼日利亚有限公司,尼日利亚装瓶公司,雀巢有限公司。和吉百利尼日利亚公司,在制定他们的广告预算的销售,从而实现,盈利能力和增加的市场份额。在进行本研究时,回顾了相关领域的文献,并向公司高管发放了问卷。样本是人口的10%,该技术是有目的地基于职位和职责。这项研究表明,在被研究的公司中,广告拨款并不是基于猜测和直觉;而是按照已知的常规方法。计算表明,在5%的置信水平下,x2临界值(3.8428)小于x2计算值(6.56),从而支持所提出的假设,即尼日利亚的跨国公司通过常规预算方法制定预算。根据调查结果,我们建议最合理的拨款方式是将各种方法结合起来,如果采用适当的媒体,则应使用适当的媒体,以达到实际的消费者,因为这将减少预算并最有可能增加盈利能力。

The calculation revealed that at 5% level of confidence, x2 critical (3.8428) was less than x2 calculated (6.56) thereby upholding the hypothesis proposed, that multinational companies in Nigeria draw up their budgets through conventional budgetary methods. Based on the findings, we recommend that the most reasonable way of making appropriations is by a combination of various methods which if applied and appropriate media should be used so as to reach the actual consumers as this will reduce budget and most likely increase profitability.","PeriodicalId":414091,"journal":{"name":"Innovation & Management Science eJournal","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124723496","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A model is built in order to study the impact of variance of demand on the supply chain inventory and also to identify the best combination of the inventory policy across the supply chain. Inventory management at independent entities is to either prevent stock out or for having lowest funds locked up. This might result in the either higher inventory holding or stock out across the supply chain. Simulation study was undertaken on four echelon supply chain. With the demand varying from 10% to 70%, the best combination inventory policy had a supply chain inventory SD varying from 11.5% to 18.9% respectively. Demand flow policy at retailer, manufacturer and supplier with s,Q policy at wholesaler would result in the least standard deviation of inventory across the supply chain for low demand variance product. Similarly, s,Q policy at retailer, supplier and s,S policy at wholesaler and demand flow policy at manufacturer is the optimum set for having least standard deviation of inventory across the supply chain for high demand variance product.
为了研究需求方差对供应链库存的影响,并确定跨供应链库存政策的最佳组合,建立了模型。独立实体的库存管理是为了防止缺货或锁定最低的资金。这可能导致更高的库存持有或整个供应链的库存。对四梯次供应链进行了仿真研究。当需求在10% ~ 70%范围内变化时,最佳组合库存策略的供应链库存SD分别在11.5% ~ 18.9%之间变化。零售商、制造商和供应商的需求流策略与批发商的s,Q策略将导致低需求方差产品在整个供应链中库存的标准偏差最小。同样,零售商、供应商的s,Q策略和批发商的s, s策略以及制造商的需求流策略是高需求方差产品在整个供应链中库存标准差最小的最优集合。

Operational Model of China's Express Services Industry: A Case Study of SF-Express 中国快递服务业的运营模式——以顺丰快递为例
Pub Date : 2015-10-21 DOI: 10.16980/JITC.11.5.201510.43

China has a very suitable environment for the development of the express industry. The growth rate of online stores in the world has exceeded the GDP growth of China and other countries. In the past five years, the express service market of China had expanded rapidly, reaching an annual growth rate of over 35%. Enterprises are engaged in this industry mainly because of the high profits, low entry requirement and great growth potential in the domestic market. This paper, through literature review, provided a case study of SF-Express, an outstanding privately operated express company in China. It analyzed the operational model of SF-Express to find out the effective means for enterprises to hone their core competitiveness for rapid development. It then used SWOT analysis to match opportunities, threats, strengths and weaknesses. This was vital for reaching optional strategic schemes for enterprises. Finally, it proposes some referential suggestions on the operational model of express companies.
中国有一个非常适合快递业发展的环境。全球网上商店的增长速度已经超过了中国和其他国家的GDP增长速度。在过去的五年中,中国的快递服务市场迅速扩大,年增长率超过35%。企业从事这一行业的主要原因是利润高,进入门槛低,国内市场有很大的增长潜力。本文通过文献综述的方法,以中国优秀的民营快递企业顺丰快递为案例进行研究。通过对顺丰快递运营模式的分析,找出企业磨练核心竞争力,实现快速发展的有效手段。然后使用SWOT分析来匹配机会、威胁、优势和劣势。这对于达成企业的备选战略计划至关重要。最后,对快递公司的运营模式提出了一些可借鉴的建议。
