However, previous studies seldom investigate about the important factors that customer needs in scenery restaurants. In this study, scenery restaurants were been focused to explore the relationship among service quality, customer satisfaction, and customer loyalty. The subjects recruited in this study were customers who have ever been to the scenery restaurant in central Taiwan. Each dimension of service quality and related important items of customer satisfaction and customer loyalty will be analyzed by the grey relational grade (GRG). The result of the study will be expected the weight of each evaluating factor including the marketing mix, the satisfaction of the service quality, the view of scenery, and the degree of what customers emphasize on in one specific scenery restaurant. The implication of the results in this study hopes to provide suitable assistance for the owners of the scenery restaurant to manage their business smoothly and exist permanently.","PeriodicalId":50187,"journal":{"name":"Journal of Grey System","volume":"12 1","pages":"147-151"},"PeriodicalIF":1.6,"publicationDate":"2009-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70058393","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Subjects applied in this study consist of the sales revenues of 7-ELEVEn and FamilyMart. This research is designed to examine the comparison analysis on these two convenience chain stores by means of such data-analysis methods as GM (1,1), RGM(superscript +) (1,1) , RGM(superscript −) (1, 1), Nonlinear Bernoulli Module, GM (1, 1) revised by Tan, and Multiple Regression Analysis. With the assistance of data analysis, this study has made it positive to prove that the pre-test results under different module applications are perceived as remained. Accordingly, under the application of top-five modules, the pre-test outcome indicates that the growth rate of 7-ELEVEn in next five years is more than 1.04% and less than 4.82%. Meanwhile, that of FamilyMart in next five years is more than 6.63% and less than 8.01%.

However, physical illness or whether there's any growth of bone lesions and the disease can only be found when the patients feel pain and go to the hospital for examination and scanning. Therefore, the purpose of this study was to combine AR Model and grey relational grade to analyze image of the thoracic cavity and spinal bone. It compares the spinal bone's spur lesions development and offers a more precise reference for doctors and patients’ family members. First of all, this paper removes the noise to highlight the clarity of spinal bones image. Further, it makes grey relational grade of AR-Model toward the spinal bones image classification model. Then, it compares and determines the spinal bone spur lesion with the model and acts as an inference and prevention toward spinal bone spur disease. So, this paper proposes to do AR-Model spectrum analysis toward medical images and makes each row's image into 256 gray level predictions by means of grey relational grade. According to this, spinal bone prediction model can make a comparison and identify the spinal bone image more effectively. After being simulated and verified, the design of this paper can actually provide a clearer spinal bone form and offer an effective image comparison warning.","PeriodicalId":50187,"journal":{"name":"Journal of Grey System","volume":"12 1","pages":"15-21"},"PeriodicalIF":1.6,"publicationDate":"2009-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70057359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
