关于客户
Comerica Incorporated 是一家总部位于达拉斯的金融服务公司。该公司为客户提供三个战略一致的业务部门：商业银行、零售银行以及财富和机构管理。该公司运营着一个由 500 多个分支机构、贷款和投资办事处组成的跨州网络。该公司运营的核心是 Comerica 在线文档 (COLD) 应用程序，这是一个供应商提供的系统，可以以电子方式归档、恢复和检索帐户报表和其他文档。该公司一直在主机磁盘驱动器上备份一个月的报表，而较旧的报表则备份在磁带上。为了缩短应用程序响应时间，Comerica 将一年的帐户报表从磁带移动到了主机磁盘驱动器。
挑战
Comerica Incorporated 是一家总部位于达拉斯的金融服务公司，为客户提供三个战略一致的业务部门：商业银行、零售银行以及财富和机构管理。在线文档系统备份账户和文档取款、存款和其他账户活动，对于拥有 500 多个分行、贷款和投资办事处的跨州网络来说，该系统必须高效运行。公司文档流程的核心是供应商提供的 Comerica 在线文档 (COLD) 应用程序，该应用程序以电子方式归档、恢复和检索这些类型的报告。最初安装此应用程序时，该公司开始在大型机磁盘驱动器上备份一个月的对账单。但是，任何超过一个月的账户对账单请求都备份在磁带上。为了提高应用程序的响应时间，Comerica 将一年的账户对账单从磁带移到大型机磁盘驱动器。该公司希望看到更好的响应时间，但事实并非如此。系统检索账户对账单所花的时间与 IT 团队实施更改之前相同。
解决方案
Reimann 的团队参加了现场 Compuware 课程，该课程演示了 Compuware Strobe 如何在 CICS 环境中测量在线活动。尽管 Comerica 已经在使用 Strobe 来测量批处理活动，但它尚未广泛用于在线环境。Strobe 能够深入 CICS 应用程序的多个层来测量实际的在线活动，这对 Reimann 的团队来说是一项宝贵的功能。使用 Strobe 配置文件报告，该团队深入研究了 SQL，以找出哪个程序语句消耗了过多的 CPU。在本例中，罪魁祸首在数据库中。仔细查看表结构后，会发现“报告日期”、“报告名称”序列与实际调用完全相反。使用 Strobe，Comerica 的 IT 团队能够节省 CPU 使用率。“Strobe 向我们展示了一个 SQL 语句占用了 60% 的 CPU 使用率，”Reimann 说。“修复问题后，我们发现 CPU 使用率降低了 25% 以上。”

Real-time In-vehicle Monitoring
The telematic solution provides this vital premium-adjusting information. The solution also helps detect and deter vehicle or trailer theft – as soon as a theft occurs, monitoring personnel can alert the appropriate authorities, providing an exact location.“With more and more insurance companies and major fleet operators interested in monitoring driver behaviour on the grounds of road safety, efficient logistics and costs, the market for this type of device and associated e-business services is growing rapidly within Italy and the rest of Europe,” says Franco.“The insurance companies are especially interested in the pay-per-use and pay-as-you-drive applications while other organisations employ the technology for road user charging.”“One million vehicles in Italy currently carry such devices and forecasts indicate that the European market will increase tenfold by 2014.However, for our technology to work effectively, we needed a highly reliable wireless data network to carry the information between the vehicles and monitoring stations.”

Safety First with Folksam
The competitiveness of the car insurance market is driving UBI growth as a means for insurance companies to differentiate their customer propositions as well as improving operational efficiency. An insurance model - usage-based insurance ("UBI") - offers possibilities for insurers to do more efficient market segmentation and accurate risk assessment and pricing. Insurers require an IoT solution for the purpose of data collection and performance analysis
Case Study
Smooth Transition to Energy Savings
The building was equipped with four end-of-life Trane water cooled chillers, located in the basement. Johnson Controls installed four York water cooled centrifugal chillers with unit mounted variable speed drives and a total installed cooling capacity of 6,8 MW. Each chiller has a capacity of 1,6 MW (variable to 1.9MW depending upon condenser water temperatures). Johnson Controls needed to design the equipment in such way that it would fit the dimensional constraints of the existing plant area and plant access route but also the specific performance requirements of the client. Morgan Stanley required the chiller plant to match the building load profile, turn down to match the low load requirement when needed and provide an improvement in the Energy Efficiency Ratio across the entire operating range. Other requirements were a reduction in the chiller noise level to improve the working environment in the plant room and a wide operating envelope coupled with intelligent controls to allow possible variation in both flow rate and temperature. The latter was needed to leverage increased capacity from a reduced number of machines during the different installation phases and allow future enhancement to a variable primary flow system.

Automated Pallet Labeling Solution for SPR Packaging
SPR Packaging, an American supplier of packaging solutions, was in search of an automated pallet labeling solution that could meet their immediate and future needs. They aimed to equip their lines with automatic printer applicators, but also required a solution that could interface with their accounting software. The challenge was to find a system that could read a 2D code on pallets at the stretch wrapper, track the pallet, and flag any pallets with unread barcodes for inspection. The pallets could be single or double stacked, and the system needed to be able to differentiate between the two. SPR Packaging sought a system integrator with extensive experience in advanced printing and tracking solutions to provide a complete traceability system.

Transforming insurance pricing while improving driver safety
The Internet of Things (IoT) is revolutionizing the car insurance industry on a scale not seen since the introduction of the car itself. For decades, premiums have been calculated using proxy-based risk assessment models and historical data. Today, a growing number of innovative companies such as Quebec-based Industrielle Alliance are moving to usage-based insurance (UBI) models, driven by the advancement of telematics technologies and smart tracking devices.

MasterCard Improves Customer Experience Through Self-Service Data Prep
Derek Madison, Leader of Business Financial Support at MasterCard, oversees the validation of transactions and cash between two systems, whether they’re MasterCard owned or not. He was charged with identifying new ways to increase efficiency and improve MasterCard processes. At the outset, the 13-person team had to manually reconcile system interfaces using reports that resided on the company’s mainframe. Their first order of business each day was to print 20-30 individual, multi-page reports. Using a ruler to keep their place within each report, they would then hand-key the relevant data, line by line, into Excel for validation. “We’re talking about a task that took 40-80 hours each week,” recalls Madison, “As a growing company with rapidly expanding product offerings, we had to find a better way to prepare this data for analysis.”
