This study proposed a method to apply certain fuzzy-related Quality control concepts to design customer-oriented products considering user requirements and information starting with the product development stage. This approach showed how to define the importance level of design elements and how to Quantify complex subjective perception of products using the fuzzy linguistic rating method and quality function deployment concepts. Using this approach, various customer requirements could be interpreted and reflected on the early design phase of a new product. To validate the proposed method, an experiment was conducted for designing the shape of the beeper using 14 subjects and 10 commercial beeper products. Front area, width/length ratio, thickness, curve variance, weight, and display area were selected as design elements of the beeper. The results showed that among design elements, front area and weight are significantly related with the subjective perception of the products. Consequently, this study indicates that customer decision on product selection could be made by quantification of user perception for beeper products.

This paper considers service deployment and priority optimization for multiple service-oriented applications sharing reusable services, which are deployed as multiple instances in the cloud. In order to handle variations in the workloads of the multiple applications, service instances of the individual reusable services are dynamically provisioned in the cloud. Also service priorities for each application in a particular reusable service are dynamically adjusted. In this paper, we propose an analytic performance model, based on a queueing network model, to predict the expected sojourn times of multiple service-oriented applications, given the number of service instances and priority disciplines in individual reusable services. We also propose a simple heuristic algorithm to search an optimal number of service instances in the cloud and service priority disciplines for each application in individual reusable services. A numerical example is also presented to demonstrate the applicability of the proposed performance model and algorithm to the proposed optimal decision problem.

The purpose of this paper is to describe a new analytic method of capital budgeting projects that takes into account both customer wants and competitor's status and to give decision makers a tool for goal setting and planning for technology. This model, which is based on quality function deployment(QFD), has used the analytic hierarchy process(AHP) to determine the intensity of the relationship between the variables involved in each matrix of the model and the 0-1 integer programming to determine the allocation of funds to various technological projects. This paper also proposes how to calculate the new weight of columns to consider various strength levels of roof matrix, representing the correlation among the quality characteristics, using Lymsn's normalization procedure. To compare this model with Partovi's model, 1 adapt the same example which is suggested by Partovi and I show that the value of object function, has maximization problem, in this model is larger than that in Partovi's model.

It has been more recent trends in container trade to make bogger ship from shipowners that many more parties concerned are getting involved. Well, it is natural to swift these situations if we have looked into container trade market in present time, which a lot of trade volumes has increased in world economy. Thus, supply side of shipping service needs to employ more capacity in the shipping market, then newbuilding may be compulsory options, that is deployment of larger ships. To cope with market situations as able shipowner, some alternatives can be also adopted, such as newbuilding, chartering and securing the space by strategic alliance. But whatever he does, shipowner has to keep in mind to prepare for the future. This is much more important factor considered to make investment decision in case of newbuilding and then he can make more efficient decision as well. However, there has been a little problems arisen due to larger ship employed on the trade route, which is linked with seaport, shipping companies and freight rates as well. Although shipowner decides to build new larger vessel as one of corporate strategic decision, there are many questions to be considered in advance. Therefore, in order to take more efficient decision, shipowner has to take into an account various situations surrounded, and then it can lead truly thoughtful decision making process.

A Kano model was used to classify the quality attributes of the service robot function for actual deployment that can support and replace bank employees. Quality attributes for a total of 6 dimensions and 23 service elements were divided into bank employees and customer groups, and service priorities were derived after comparative analysis. The Decision tree model was used to supplement the excessive simplification of quality attributes by the modest number of Kano models and to classify and predict by segment market. Of the 23 services, 16 were classified into the same attributes in both groups. 6 services classified as combination attributes used a Decision tree to identify differences in perception of quality attributes among groups. In terms of basic financial services and professional financial services, it was confirmed that bank employees feel financial service robots more attractive than ordinary customers. In the design of IT convergence service, we propose a methodology for deriving quality attributes by combining a Kano model for classifying quality attributes of two groups and a Decision tree for forecasting subdivision markets.

클라우드 서비스 및 운영 방식이 다양해지면서 선택할 수 있는 클라우드 컴퓨팅의 종류가 많아지고 있는 만큼 금융회사에는 각 전산시스템에 적합한 클라우드를 선택할 수 있는 의사결정 방법이 필요한 상황이다. 본 연구에서는 기업의 비전 및 전략 수립을 위해 사용되는 BSC(Balanced Scorecard, 균형성과 관리) 프레임워크를 활용하여 금융회사에서 클라우드 도입을 위해 고려해야 할 요인들을 BSC의 4대 관점(재무, 고객, 내부 프로세스, 학습과 성장)에 따라 분류하고 최종 12개의 고려 요인을 선정하였으며, 다기준 의사결정 방법 중의 하나인 AHP(Analytic Hierarchy Process, 분석적 계층 프로세스) 기법에 따라 평가 항목들을 성과 평가 관점과 클라우드 고려 요인으로 계층화하여 최종 의사결정모형을 제안하였다. 나아가 금융회사의 시스템을 계정계, 정보계, 채널계 시스템으로 구분하고 금융회사 두 곳의 금융 전문가와 정보 기술 전문가의 의사 결정 결과를 취합하여 각 시스템 별 클라우드 도입 시 고려 요인에 대한 중요도 및 클라우드 운영 모델의 적합도에 대한 비교 분석을 수행하였다. 분석결과 모든 시스템에서 공통적으로 중요하게 평가된 일부 고려 요인도 있었지만 대부분의 고려 요인은 시스템 별 중요도가 매우 다르게 평가되었으며, 실제 시스템 별 적합한 클라우드 운영 모델은 서로 상이하였다. 이를 통해, 각 금융회사에서는 클라우드 컴퓨팅 도입 시 각 시스템 별 클라우드 고려요인을 평가하여 운영 모델을 선정해야 한다는 시사점을 주었으며, 더불어 본 연구에서 제시하는 일련의 절차와 방법론을 통하여 금융회사의 클라우드 컴퓨팅 도입에 대한 인식을 제고하고 클라우드 컴퓨팅 도입 확산에 기여할 것으로 기대한다.
