SOA(Service Oriented Architecture)는 시스템 통합 프레임워크로서 그 중요성이 날로 커지고 있다. SOA 프레임워크를 통해 애플리케이션이나 기업 시스템은 보다 융통성 있게 통합될 수 있으며, 사용자들은 보다 다양한 비즈니스 모델을 구성할 수 있다. 하지만, SOA가 현실적으로 폭넓게 기업현실에 적용되기 위해서는 SOA 서비스 수준의 관리가 절실하다. 이러한 측면에서, 최근 IT 서비스 부문의 표준 관리체계로 각광받고 있는 ITSM을 활용하여, SOA의 서비스 품질을 일정 수준 이상으로 유지할 수 있도록 하는 방안에 대한 연구가 필요하다. 본 논문에서는 SOA의 구현체계로서 웹 서비스 시스템을 채택하여, 필요한 품질 항목들을 ITSM의 관리영역에서 살펴보고, 품질 항목의 수준을 일관성 있게 유지하기 위해 필요한 새로운 관리체계와 SLA 방법론에 의한 협상/계약 체결에 대해서도 방안을 제시하고자 한다.

An interesting problem in capacitated supply chains is how to guarantee customer service levels with limited resources. One of the common approaches to solve the problem is differentiating service depending on customer classes. High-priority customers receive a better service at the cost of low-priority customers' service level. One of common criteria to determine a customer's priority in practice is whether he has made a reservation before arrival or not. Customers with a reservation usually receive service based on the time the reservation was made. We examine the effect this advance information of customer arrival has on customer service levels. We show the trade-offs between the leadtime and other system characteristics such as the proportion of high-priority customers. when the service level is high. We also suggest how to differentiate service using the asymptotic ratio of the service levels for both types of customers.

This study try to find the service quality factors of internet-based lecture and in-class lecture on the university level. The service quality factors of internet-based lecture are information quality and system quality factors which affect education service value, and customer satisfaction. This affects the service performance. The service quality factors of in-class lecture are tangibility, reliability, responsibility, assurance and empathy factors also affect education service value and customer satisfaction. This leads to service performance. This result will be helpful to enhance the service quality of university level lectures.

본 연구는 위기관리체제 구성원들의 테러대비에 관한 인식수준을 분석함으로써 소방 업무를 담당하는 자치단체 위기관리 담당 공무원과 소방공무원들의 테러에 대한 인식차이를 도출함으로써 예방의식수준을 제고할 수 있는 기초자료를 제공하기 위한 목적으로 수행되었다. 이를 위해 위기관리 담당공무원의 전문성, 위기대비체제수준, 위기관리체제간의 협력 등에 대한 우선순위를 설문조사를 통하여 측정하였다. 분석결과 테러대비의 측정변수에 대한 우선순위에 대해서는 응답수준의 차이는 있지만 구성원들 모두 그 중요성에 대하여 인식하고 있는 것으로 나타났다.

The purpose of this study is to investigate the intention to utilize u-healthcare services in Korea. Specifically, this study attempted to identify the relationships among the intention to use u-healthcare, consumer's demographic characteristics, and personal information technology level. We conducted telephone interview and collected data from 406 householders 20 years old or older. The results showed significant differences in use intention of u-healthcare service by innovation, gender, and their interaction term. Residence area and average time of internet use had significant effect on the use intention of u-healthcare service. Also, the interaction term between innovation and education level had a significant effect on use intention. Based on the results we concluded that the consumer's characteristics and information technology level had a significant effect on the use intention of u-healthcare service.

This study examines the effects of competency and service orientation of imported fashion luxury brands salespersons on the organizational commitment and service delivery level. Questionnaire data from 162 salespersons of imported fashion luxury brands were analyzed. The results were summarized as follows. First, self-management ability, professional executive ability, and the friendly attitude of six competency factors had significant effects on organizational commitment. Second, professional executive ability, self-management ability, and friendly attitude of the six competency factors had significant effects on service delivery level. Third, all factors of service orientation had significant influences on organizational commitment. Finally, special treatment/awareness of needs and instant response/communicative skill of three service orientation factors had significant influences on the service delivery level.

The current trend toward the utilization of the Internet as a common means for the offer of heterogeneous services imposes to address the issues related to end-to-end service assurance in the inter-domain scenario. In this paper, we first present an architecture for service management in networks based on service level specifications (SLS). The architecture is designed to be independent both of the specific network technology adopted and of the high level service semantics. Then, we focus on a specific functionality of the proposed architecture: Resource allocation in the multi-domain scenario. A distributed admission control algorithm is introduced, its complexity is evaluated and a comparison with related solutions is provided.

The main objective of this research is to develop a model to select the optimal input service level for a distribution center-multi branch inventory distribution system. With the continuous review policy, the distribution center places an order for specific order quantity to an outside supplier, and the order quantity is replenished after a certain lead time Also, each branch places an order for particular order quantity to the distribution center to satisfy the customer demands, and receives the replenishment after a lead time. When an out of stock condition occurs during an order cycle, a backorder is placed to the upper level to fill the unfilled demands. With these situation, variable demand and variable lead time are used for better industrial practice. Further, actual lead times with a generic lead time distribution are used in developing the control model. Under the actual lead time model, the customer service measures actually attained for the distribution center and each branch are explained as the effective customer service measures. Thus, throughout the optimal control (using computer search procedures), we can select the optimal input service levels for the distribution center and each branch to attain the effective service levels for each branch which is consistent with the goal level of service for each branch. At the same time, the entire distribution system keeps minimum inventories.

This paper proposes an approach to analyzing the relationship between technology and services, and to identifying promising service areas for technology-based firms with the analysis of business model (BM) patents. First, BM patents and technology patents are collected and classified into their relevant categories, respectively. Second, patent citation analysis is conducted to analyze the linkage and impacts between each technology and service field at macro level. Third, as a micro level analysis, patent co-classification analysis is employed to identify the interrelationships among specific technology and service areas. Finally, the promising service areas for technology-based firms seeking service areas for diversification is investigated with portfolio analysis. The working of the proposed approach is provided with the help of a case study of IT and mobile services. The proposed approach could guide and help managers of technology-based firms to discover the opportunity of the diversification to new areas in emerging service fields.

Supply chain management is a total systems approach to delivering manufactured products to the end customer. Using information technology to coordinate all elements of the supply chain from parts suppliers to retailers achieves a level of integration that is a competitive advantage not available in traditional logistics systems. On the other hand, service chain management is an analogous systems approach that is especially suitable for delivering mobile services such as parcel delivery, cable installation, and home health care. The key elements that distinguish service supply chain management from supply chain management are bidirectional optimization, management of productive capacity, and management of perishability. The purpose of this study is to maintain the construction of service chain management by proving that service quality in after-sales service can be improved through service chain management. First of all, supply chain management, service quality, and service chain management were introduced in theoretical research. In empirical research, it was selected the domestic enterprise that produce electronic appliances with after-sales service, and some customers using the enterprise's after-sales service in the metropolitan area were selected as a sample by convenience sampling method and examined.
