Recently business enterprises have forced to face in fierce competition in today's global markets due to the short life cycles of products and the higher expectation of customers. Together with continuing advances in communications and transportation technologies, these environments have motivated the continuous evolution of the supply chain and the management techniques. This paper consider three-echelon inventory system which consist of one manufacturer, one distributor and N retailers for a single product under assumption of constant demand. This paper propose the inventory replenishment period using heuristic method and order policy through coordination of inventory replenishment period. The simulation results show that decrease the total cost of the three-echelon inventory system.

The purpose of this study is to present HACCP management method for improving customer satisfaction in bakery industry. As a study method, literature review on HACCP and customer satisfaction and developing questionnaires through model design were done. Then, a survey was done to 209 customers who had experiences of visiting small size bakeries in Seoul or the national capital region. It was then statistically analyzed and examined. In conclusion, even though the respondents showed positive expectation that the certification of HACCP will have an effect on the factors of customer satisfaction like brand image, quality of product and service, facility and physical environment and so on, but as we proved in the course of study model's hypothesis confirmation, actually, current promoting efforts and strategies of the government or related institutions to spread recognition of HACCP don't have an meaningful effect on the factors of customer satisfaction.

The research objective is to empirically investigate the compensation packages maximizing the utilities of internal customers by applying the market segmentation theory. Data was collected from four Korean hospitals in Seoul, Busan and Gyunggi-do. The research is designed to seek the compensation package maximizing the utility of doctors by mixture regression model, which has been applied as latent structure and other type of finite mixture models from various academic fields since early 1980s. The mixture regression model shows the optimal segments number and fuzzy classification for each observation by EM(expectation-maximization algorism). The finite mixture regression model is to unmix the sample, to identify the groups, and to estimate the parameters of the density function underlying the observed data within each group. The doctors were segmented into 5 groups by their preference for the compensation package. The results of this study imply that the utility of doctors increases with differentiated compensation package segmented by their preference.

The service offer expectation and the desire of customers to a large-sized rate influence store also increase as a result of such environmental change. the counter where research of a book was upgraded from differentiation pursuit by competition between business condition in business condition in the case of the domestic rate influence store which has put the focus on service strengthening The work shrine which cannot reach here the competition predominance in the domestic market it will be hard coming to secure, when environmental change of inside large-sized rate influence store industry is taken into consideration The research which tried to receive customer service failure recovery carried out actual proof analysis in the influence to which fair nature lateness of a customer attains to the re-purchase intention to this store of customer satisfaction and future by service recovery process for an object in the customer who held service failure recovery experience in the domestic large-sized rate influence store.

Recently, it is not sufficient that contemporary firms satisfy customers to be really successful, they must create new value. To do so, many firms focus on the blue ocean strategy. The blue ocean strategy proposed the strategic canvas as a main tool for identifying the opportunities for value differentiation. It is easy to understand and for the use, but has weakness that is a unclear procedure to make it done. To complement its weak point, this study proposes a refined strategic canvas based on the concept of the business evolution that comes from a discontinuous evolution trend of 5 stages known as customer expectation.

This research addresses examining the service recovery process in Airline service. A service recovery framework is suggested and tested empirically. The framework includes several factors such as service recovery expectations, service recovery achievements, recovery performance, post-recovery satisfaction, and post-recovery behavioral intents. The relationships among these factors are hypothesized and proved empirically. Consequently the results suggest that recovery expectation impacts on recovery performance significantly. Also the higher the recovery performance, the higher post-recovery satisfaction, then it increases customers' purchase intent and words of mouth. Finally, this paper suggests the need for new service recovery strategies.

A design needs various experience and design knowledge through a whole design process. Despite of all efforts and time, it is not easy to introduce a product that meets all customer's needs and expectation in time. To achieve the product goal, designers need a set of sequential process to find appropriate design parameters and ensure customers' needs and requirements. In this research we propose a design methodology for the initial design of an excavator front group with existing QFD(Quality Function Deployment) and Axiomatic Design to satisfy customer's requirements. It turns out that the proposed methodology can support designers more effectively, objectively, and systematically.

본 연구의 목적은 미국 의류점포의 판매규정과 고객의 점포에 대한 기대가 판매원과 소매점에 대한 만족과 평가에 미치는 영향을 조사하는 것이다 미국에 거주하는 한국 소비자들을 대상으로 먼저 시각적으로 분위기가 다른 두 점포에 따른 고객의 서비스에 대한 기대를 측정하기 위해 슬라이드를 보여주고 의류업체의 판매규정에 따른 의류에 관련된 문제상황을 설명해주는 시나리오(판매원 노력에 의한 문제 해결 또는 소비자 노력에 의한 문제해결)를 읽게 한 후 설문지를 작성하게 하였다 그 결과 업체의 판매규정이 판매원의 서비스에 대한 만족도와 평가 의류점포서비스에 대한 만족도와 평가에 영향을 미치는 것으로 나타났다.

The purpose of this study is to prioritize the importance of urban railway service quality through statistical analysis. This was done to maximize customer satisfaction by providing customers of urban railway services (including LRT), operated by the local government, with a better customized service quality. It was hoped that this project would boost the need for public transportation by increasing customer satisfaction, which would eventually lead to more profitable revenue. The results of validity certification of expectations and perceptions before and after the use of government funded urban railway and private sector invested urban railways show that there are gaps for 18 items for the government funded urban rail projects (p<.01), while there is no significant difference for 2 items between expectation and perception (p>.05); private sector invested urban railway projects show differences for all 20 items (p<.001). Therefore, IPA analysis is conducted to improve the service quality; this should lead to a remedy that focuses on service quality. The findings of this study will contribute to providing management strategies for boosting customer satisfaction and creating revenue through customized service quality in the urban railway operating industry (including LRT), which is currently suffering from chronic deficits.

I-Business providers and customers have chosen the service availability as the most important technical parameter which should be included in their SLA to succeed in their business. This means that web Service availability management is crucial to the web-based service providers. Application availability is originally defined as a measure of the fraction of time during a defined period when the service provided is deemed to be better than user expectation of service performance. But, because most web service availability measurement tools simply monitor disconnected state, they do not satisfy user's expectation of extended availability concept. In this paper, We propose the web service availability measurement method which supports extended availability concept. It takes account of performance degradation of web service based on response time, and determines what is the cause of unavailability of the service. We developed a measurement tool, WebSerAvail.
