  • In this paper, we consider a system working at both primary service and secondary service. A server can switch between the primary service and the secondary service or it can be assigned to secondary service as a dedicated server. A service policy is characterized by the number of servers dedicated to the secondary service and a rule for switching the remaining servers between two services. The primary service system is modelled as a Markovian queueing system and the throughput is a function of the number of servers, buffer capacity, and service policy. And the secondary service system has a service level requirement strategically determined to perform the service assigned. There is a revenue obtained from throughput and costs due to servers and buffers. We study the problem of simultaneously determining the optimal total number of servers, buffers, and service policy to maximize profit of the system subject to both an expected customer waiting time constraint of the primary service and a service level constraint of the secondary service and develop an algorithm which can be successfully applied with the small number of computations.

  • Purpose - This study focuses on "large-scale marts," which is a typical discount-based retail channel (hereinafter, DRC), and provides practical managerial implications by applying the KD-SQS service quality factor based on customers' experiential perspective by developing and applying existing service measures. Research design, data, and methodology - The research subjects include adults who have experienced "large-scale marts." The research involved SPSS 20.0 and AMOS 19.0 packages; path analysis is used to analyze structural relationships. Results - First, physical aspects, human interaction, and additional convenience aspects of service quality have statistically significant influence on service value. Second, physical aspects, human interaction, and policy have statistically influence on store loyalty. Third, service value influences store loyalty. Fourth, service guarantee adjusts the relationship between service quality, service value, and store loyalty in terms of human interaction and policy. Conclusion - Among service quality measures, improving service value through personal service needs to be prioritized, while we need to develop different methods for the service guarantee system to effectively influence service value and store loyalty.

  • Recently, firms which have offered a "free Internet service" to their customers, are considering a "charged Internet service" for increasing a company's profit. But they have doubts about the results, because consumers may fly away from their web-site easily and may discontinue using their services. The purpose of this study is to investigate which factors make consumers use the charged Internet services. To do this, the factors, which are ease of using the service, usefulness of the service, the reputation of the service provider, service cost, and the intention to use the service as a mediator, are analyzed. To achieve this research objective, a structural equation model was constructed and a field study method was used. The findings are summarized as follows: First, ease of using the service, usefulness of the service, and service cost have significant impacts on the charged Internet service usage through the intention to use. Especially, although service cost influences on the service usage largely, the usefulness of the service has a bigger impact on the charged Internet service usage than service cost. Second, the reputation of the service provider does not have any impact on the service usage. Third, consumers using only the free Internet service tend to hesitate about using the "charged Internet service" because they doubt its ease of use and usefulness in spite of the service cost.

  • Objective: This paper discussed the characteristics of service design process by comparing with product design process. Background: Service design has different design outcomes, project participants, and design constraints than product design. Method: The comparison took two perspectives: one was shorter-term, design process of a service, and the other was longer-term, process of service development. Results: It was discussed that service design process is similar in overall, but has four differences. First, the role of design is required earlier and longer in the process, which means service designers need to participate from the begging of the project to service operation. Thus service designers are required to have holistic viewpoint of the project. Second, service design requires many design expertise thus collaboration needs to be well defined and managed throughout the process. Third, since service provider has limited resources, regulations, and market competition, some service features cannot be provided. Service designers are required to know both customers' needs and functional constraints. Last, service design is highly coupled with service operation. Designing and providing service happens at the same time and evolves over time. Conclusion: Consequently it was asserted that the role of designers in service design is essential for success. In specific, the role of service design architect, who manages design process and design outcomes, is a new and important role in service design project.

  • Purpose - This study aimed to develop a new practical and universally applicable service quality model by improving the service quality measurement model proposed by many previous studies. Research design, data, and methodology - An in-depth analysis on what influences such service quality model had on the improvement effect of service quality, and Service Evaluation Model("SEM"), which was revised from the existing service quality measurement model, was developed. The model is divided into the two integrative categories: First, activity, that is the group of service-related activities. Next is item, the group of service-related objects. The level of service is evaluated for each category via survey questionnaire on service level evaluation. Based on the model, SEM has visibility by structuring the whole service industry. Results - For the application of the new service quality model, this study attempted to examine the appropriateness of the newly proposed service quality model by applying it to retail service field. Conclusions - As a result, the proposed service model would be a useful and applicable service quality measurement model required by many organizations. Service company can set up self check service levels. Through these results, they can look for the ways to provide better services to customers. Service users can ensure the objectivity of business plan based upon SEM.

  • This paper proposed a service satisfaction index in the service design. We utilize the service blueprint as the basic tool for the service process analysis, construct a service flow fishbone diagram which consists of the encounters representing the interaction between customer and service deliverer. To evaluate the service satisfactions of the service element a service satisfaction function is used. The service satisfaction function has the generic properties of the prospect theory with the probabilistic utility value in order to evaluate the service bundle which Is constructed by tangible and intangible service elements. A numerical example using the A/S service of Electronic Co. is presented for the verification.
