Recent power industries are to be progressed as moving into horizontal markets and expanding of competitive systems through promoting SmartGrid. In these environments, the information on power consumers leads to establish a part of power markets through active and real-time participations instead of participating it as a passive manner presented by a vertical integration. Also, such information should be established as a way that effectively reflects changes and market behaviors occurred in power market participants. Therefore, in this study, a method that develops consumer information models, performs integrated managements, implements registration and distribution, and forms integrated management centers is presented to commonly use the consumer information according to the change in the environment of power industries.

The study on the user-centered interior design of trains consists of the practice of sensitive technology for the management of customer's emotions and its harmonical use on design and it aims on the embodiment of new ergonomics design. In the center, it has analyzed the criteria and characteristics for the 'User First Design' and has concluded the design direction and components to a concrete idea and proposed prototypes, which may becomes a good example for train interior design later on. And not at least it proposes a direction which may become a guideline of ergonomic design to secure competition capacity.

최근 들어 CRM이 확산됨에 따라 고객과의 접점에서 업무를 담당하는 콜센터의 중요성이 커지고 있으며, 정보기술이 발전함에 따라 콜센터 본연의 업무를 넘어서 콜센터에 새로운 역할이 부가되고 있다. 지금까지 콜센터에는 기계와의 커뮤니케이션에서 발생하는 거부감, 과다한 대기시간, 새로운 통신수단들로 인한 콜센터의 기능약화, 적절한 정보의 적시 사용의 어려움, 기술투자 선행작업의 미약 등의 문제점이 지적되었다. 하지만 무엇보다도 가장 큰 문제점은 명확하게 수립된 경영전략과 운영전략이 없었다는 것이다. 이에, 고객, 서비스 전략, 인적 자원, 프로세스, 정보기술 등 다섯 가지 영역으로 나누어 다른 기업과의 차별화를 달성할 수 있는 콜센터의 경영전략을 수립해야 한다. 고객의 측면에서는 만족되지 않고 있던 고객욕구를 경쟁기업보다 앞서 제공해야 하고, 서비스 전략 측면에서는 고객과의 거래비용을 줄여줄 수 있는 전략이 필요하다. 인적자원 측면에서는 보다 전문적인 서비스를 제공할 수 있는 능력을 보유한 종업원을 콜센터에 배치해야 하며, 프로세스 측면에서는 콜센터를 통해 업무창구를 일원화하는 방향으로 업무 프로세스를 리엔지니어링 해야 한다. 끝으로 정보기술 측면에서는 인터넷과 콜센터를 통합할 수 있는 방안을 모색해야 한다. 그리고 이상과 같은 경영전략 하에 구축된 콜센터의 성과를 극대화하기 위해서 필요한 8가지 운영전략을 도출하였다.

DSTC(Defense Systems Test Center) in ADD(Agency for Defense Development) performs a test for various kinds of weapon system. In order to provide accurate test measurement data relating to the weapon system's performance with customer, A reliable test process and an objective analysis of the measurement data are required. DSTC is trying to apply CMMI(Capability Maturity Model Integration) Ver 1.2 in a test process. In this paper, we present the result of CMMI Engineering Process Area Modelling of Test Process.

The Purpose of carrier tracking and tracing is to achieve more information over shipments via carrying in mobile business .At multimodes, especially consignor wants to be aware of the exact situation and position of goods. As an innovate business model, we present CGPS(Carrier Global Positioning System) scheme usiug LEO(Low Earth Orbital) satellite. The LEO collects the data periodically and sends to the web server, and eventually customer's PC or PDA. This provides shipping company or freight forwarder with more robust information such as door status, container inside condition, etc.

Initial reliability prediction done by calculation would be more practical if support by evidence from customer usage profile and field failure data to improve the prediction. Thus, the consistency of the design and the product would be practically validated. In this paper, it will address rationale and method to decide on Acceleration Factor (AF) to be used in Accelerated Life Test (ALT) through usage profile and field failure. The case study of tractor transmission is used to demonstrate the method which data obtained from surveys done on farmers, field visits and field failure data from service center. By considering all the elements, it will determine more relevant AF which indicates the real use conditions of the component.

This paper deals with ordering policies of consumable goods which have large demand rates in a multi-level distribution system. The system we are concerned consists of one Central Distribution Center(CDC) and N non-identical Regional Distribution Centers(RDCs) which have different demand rates, minimum fillrates, leadtimes, etc. The customer demand on the RDC is stationary poisson and the RDCs demand on the CDC is superposition of Q-stage Erlang distributions. We approximate the RDCs and CDC demand distribution to nomal in order to enhance the efficiency of algorithm. The relevant costs include a fixed ordering cost and inventory holding cost, and backorder cost. The objective is to find a continuous-review ordering policy that minimizes the expected average costs under constraints of minimum fill rates of RDCs and maximum allowable mean delay of CDC. We developed an algorithm for determining the optimal ordering policies of the CDC and the RDCs. We verified and compared the performance of the algorithm through the simulation using the algorithm result as the input parameters.

Especially, MTO(Make-To-Order) companies take collaborative approaches with their partner companies to make low-price products and/or technologically low intensive products. The collaborative approach to manufacturing requires collaboration with partner companies for inventory review, production plan, and manufacturing to fulfill customer's orders. However, frequent changes of partnerships binder partner companies from sharing production information in effective ways since their information systems have different data architectures and platforms. Therefore, it is required flexible and standardized system integration approach fir effective information sharing. This research studies current status and problems of collaborative production system, proposes an architecture for collaborative production systems based on Web Services which is a standard information technology, and discusses expected effects and the vision of Web Services.

A telecooperation system supports synchronous cooperation among all the product development partners and enables compensation of deficits concerning traditional information/communication technologies. By analyzing the product development processes and communication scenarios of a company manufacturing automobile parts, the specifications for the suitable telecooperation system were defined. An integrated telecooperation platform that combines the commercial softwares with the new developed modules for customer-oriented functionalities was created as a product development guideline. Future work is strongly required in order to define the best way to improve the integrated platform, based on the functionality of ERP and PDM systems.

This paper presents a decision support system (DSS) for selecting the best delivery policy at an internet general shopping mall with its own distribution center and many outside enterprises linked up with the mall. The DSS provides the decision maker with the performance information of three delivery policies (individual delivery, collective delivery, mixed delivery) for the given service level, customer order pattern, direct/indirect delivery ratio, unit costs of various delivery modes, upper level of goods characteristic index for collective delivery poller, etc. Furthermore, the DSS allows the decision maker to perform the sensitivity analyses of three delivery policies for their major parameters and unit costs of delivery modes. The DSS is developed with AweSim simulation 1anguage and Visual Basic programming 1anguage.
