The purpose of this paper is to improve the service tree analysis introduced recently by Geum et al. [15]. Service tree analysis structures the service based on the customer participation perspective and provides a qualitative analysis method categorizing the service elements on the basis of its impact to top service. This paper attempts to apply the concept of reliability importance to the service tree analysis as a perspective of quantitative analysis, which is considered little in Geum et al. [15]. Reliability importance is a measure of the structural impact of the components that make up the system on the system lifetime in reliability engineering field and often used in fault tree analysis. We transform the reliability importance into service importance in accordance with service tree analysis, so that the influence of service elements on the service can be judged and compared. The service importance is defined as the amount of change of the service according to the change of the service element, therefore, it can be utilized as an index for determining a service element for service improvement. In addition, as an index for paired service elements, the relationship between the two service components can be measured by joint service importance. This paper introduces conceptual changes in the process of applying reliability importance to service analysis, and shows how to use the service importance for identifying the priority of service element for the final service and improving customer satisfaction through an example. By using the service importance and joint service importance in service tree analysis, it is possible to make efficient decision making in the process of determining the service elements for analyzing and improving the service.

We performed an importance analysis of In-Service Testing (157) components for Ulchin Unit 3 using the integrated evaluation method for categorizing component safety significance developed in this study. The developed method is basically aimed at having a PSA expert perform an importance analysis using PSA and its related information. The importance analysis using the developed method is initiated by ranking the component importance using quantitative PSA information. The importance analysis of the IST components not modeled in the PSA is performed through the engineering judgment, based on the expertise of PSA, and the quantitative and qualitative information for the 157 components. The PSA scope for importance analysis includes not only Level 1 and 2 internal PSA but also Level 1 external and shutdown/low power operation PSA. The importance analysis results of valves show that 167 (26.55%) of the 629 IST valves are HSSCs and 462 (73.45%) are LSSCs. Those of pumps also show that 28 (70%)of the 40157 pumps are HSSCs and 12 (30%) are LSSCs.

With the advancement of technology, the market size of online bookstores is constantly increasing in Korea. Despite the importance of the quality of services provided by online bookstores as many customers use online bookstores, many existing studies have approached only from a linear perspective that satisfying service quality factors will lead to customer satisfaction. In addition, the service quality of online bookstores has only been addressed in general and universal service situations, such as SERVQUAL and e-SERVQUAL and WebQual, or online situations. This study was conducted to consider the specificity of online bookstores and to establish specific strategies for improving service quality. In this study, we present six higher dimensions of service quality for online bookstores and 25 lower dimensions to measure it, and we confirm strategic direction for service quality elements through IPA analysis. As a result of the analysis, a total of 12 factors were included in the first quadrant, which required maintenance of service quality due to the high importance and satisfaction perceived by customers. Next, the importance of customers is high, but their satisfaction is low, so the second quadrant that should be improved first had a total of two factors. Third, the third quadrant was an area where customers perceived low importance and satisfaction, and a total of nine factors were involved. Finally, the fourth quadrant was an area where the customer was satisfied but perceived low importance, with a total of two factors. The results of this study can be used as basic data for strategic use of online service quality factors.
