The Internet enables businesses to acquire a great deal of information, including prices in the open markets. In this study, we investigate what the value of reference price information is to a company in the market and how the company can make use of such information. Using business analytics, we were able to estimate prices of used cars for a rent-a-car company. The results show that a smart pricing information system is useful for collecting online reference price information and for estimating future prices of used cars and rental prices.

Congestion is a growing concern of many global cities and the demands on Infrastructure services within a locale coupled by the rising expectations from the growing population places stress on these cities. This entails the ability to build a sustainable community that requires an understanding and recognition of Population growth, changing demographics and the ever changing urban development on both a macro and micro level. Infrastructure is an integral part of Australian economy, particularly the 'Infrastructure Assets Management' which highlights the importance towards the development of sustainable communities for Melbourne's future. Melbourne 2030 is a comprehensive representation of government's response to a wide-ranging population growth within Melbourne metropolitan and surrounding areas. Urban plan and specific Infrastructure Assets Planning needs not only to provide sufficient Infrastructure to a community, but it must also be efficient and innovative so that it produces an optimised management system. A system that incorporates engineering techniques that will be sustainable for decades to come by maintaining an acceptable level of services to its intended community in an effective manner, which also strengthens service delivery. The fundamental challenges for optimization of Infrastructure with the Melbourne urban plan is, the ability to manage and sustain maintenance of Infrastructure to provide the acceptable level of service required by the community in a most effective manner which also strengthens service delivery to contribute towards Melbourne 2030. This paper particularly investigates some of the fundamental issues within the Melbourne urban plan such as Infrastructure Asset Management, AusLink and the Australian Road Management Act 2004, which the Governments at all levels must deal with to provide an economically viable solution to the changing Infrastructure so it may suits the needs and services the strategies of a metropolis.

Datawebhouse consists of both web log analysis used for customer management and datawarehouse used for decision support. However, datawebhouse needs complex operations for management in order to transform and integrate data from heterogeneous data sources and distributed systems. We propose a metadata schema in order to enable data integration and data management which are essential in datawebhouse environments. We show that our proposed schema supports datawebhouse development and enables integrated asset management of business information. With ETL metadata for web log extract, we can improve the data processing time of web log.

Most of the national critical key infrastructure, such as power, piped gas and water supply facilities, or the high-speed railroad, is run on the SCADA system. Recently, concerns have been raised about the possibility of these facilities being attacked by cyber terrorists, hacking, or viruses. Thus, it is time to adopt the relevant security management techniques. This paper attempts to propose such security management techniques, including information protection measures and troubleshooting, based on a risk analysis process concerning assets, threats/vulnerability, and hazards, and to examine the security management status of critical key infrastructure in the U.S. and Japan.

Using the 2007 Fund Investors Survey, we investigated (1) the differences in economic status in terms of household income, consumption, saving, assets and debts, (2) the differences in financial management behavior, (3) and the differences in confidence in economic status after retirement between households conducting and not-conducting financial preparation for retirement. The major study findings were as follows. First, only 46.4% of the households were financially preparing for retirement. The levels of income, consumption, and saving were higher among households conducting financial preparation for retirement than among those not-conducting such financial preparation. Second, households conducting financial preparation for retirement had a relatively high propensity to save. Their financial asset portfolio had a higher weight in safety assets and investment assets than in retirement assets. Due to their lack of confidence in their economic status after retirement, their demand for financial preparation for retirement remained. Third, the households which did not conduct financial preparation for retirement tended to have a relatively heavy debt burden and not to implement general household financial management practices. Fourth, among the three-pillar retirement income system, the second pillar, of individual retirement account was not well established. Based on these results, various implications were suggested.

Nowadays, SCM(supply chain management) is recognized as a efficient way to overcome the limits of asset and capability of one fun through the synergy effects comes from strategic alliance. Traditionally material management and logistics are recognized as a simple functional activity. But as the importance and needs of customer service are increased, gradually these activities are given to strategic role of cutting off the cost and increasing the sales. But unlike traditional alliance, for example technology alliance or holding facility in common, SCM has many difficulties in action because of differences in organization structure and management system between two firms. So in this paper, I will review literatures about the concept and constructing factor of SCM, the conditions for effective doing and strategic implications.

Information System is a critical success factor for overcoming the limitations of asset and capacity of Small and Medium Enterprises (SME), and for acquiring competitiveness. Although, the rate of adopting information system by SME has grown, the rate of its utilization has been stagnant. The purpose of this study is to identify the influencing factors that increase SME's information system utilization. We identify perception of strategic value, supplier's support capacity, and organizational characteristic by examining previous researches on information system utilization by SMEs, and verify their the influencing relationship with the information system utilization. This study verifies the research model and hypothesis using structural model. A date-set of 1209 samples from a survey on employees in charge of information system of SME was applied in verifying the research hypothesis. The result of this study shows that the information system utilization influences perception of strategic value and support of supply company, and partly, the structural characteristics. This study presents directions to establish strategy and policy making, and theoretically presents core factors of SME's information system utilization.

The product lifecycle of a marine vessel can be classified into the design-production, operation-maintenance, and disposal phases. During the operation and maintenance phase, status data should be gathered from the major machinery and instruments installed on the marine vessel in order to perform efficient maintenance work. Although a PLM (product lifecycle management) system can manage the product information during the design and assembly stage, a PLM based on asset management technology is more appropriate for product information management during the operation stage. Product embedded information devices (PEIDs) are suggested for gathering real-time maintenance information during the operation and maintenance lifecycle. A PEID allows PLM to provide the capability of offering active information exchange between the lifecycle management system and equipment. This study designed a PEID to effectively obtain information and interact with a PLM system. It consists of sensors, wireless communication, and a micro-processor, which allow it to accumulate status data on the PLM system. The embedded information device and PLM enable the seamless information flow, tracking, and updating of MRO (maintenance repair and overhaul) information for a product throughout the middle of the product lifecycle.

The application of spatial information has drawn significant attention from a wide range of industries. Railway spatial information facilitates the cooperation among related parties and improves the efficiency of asset management and operations. This study proposes the structure of Railway Object IDentifier(ROID) on railway spatial information. Current facility management and train operation are based on relative positioning system. Despite many advantages, relative positioning system causes serious problems such as the entire reconfiguration of positioning in the case of line change. Another major concern is the interface compatibility between individual facilities with different relative positioning. ROID based on absolute positioning addresses these issues, allowing the information exchange and convergence between independent parties. This study proposes ROID based on OID standard with object IDentifier and service object-oriented reference system. Our ROID employs the absolute positioning and the unique identifier, maintaining the compatibility with existing management system.
