As one of the most effective way for improving food quality and safety, how to promote logistics ability of the Cold-Chain enterprise has become an emergency issue. This paper aims to build a performance evaluation system for the cold-chain company based on the Chinese agri-food industry to analyze its strengths and weaknesses for improving its competitiveness. Improved Analytic Hierarchy Process (AHP) and Fuzzy Comprehensive Evaluation methods are blended to evaluate the performance of the target company in three steps. In the first step, rely on the AHP, with the literature review and the theory of the balanced score card method, the determination of evaluation criteria and the hierarchical structure of the evaluation index system are done. In the second step, the weights of each criterion are obtained through improved AHP and then an agri-food cold-chain logistics enterprises performance evaluation index system will be built. And, in the third step, the Fuzzy Comprehensive Evaluation method is used to evaluate the performance of the target company with the performance evaluation index system. Finally, a demonstration of the numerical example in Chinese agri-food industry is presented for better understanding. The proposed performance evaluation index system can assist managers to comprehensive comprehend the strengths and weaknesses of their agri-food cold-chain companies and could continuously improve the relevant cold-chain performance factors from the practice.","PeriodicalId":211783,"journal":{"name":"2015 12th International Conference on Service Systems and Service Management (ICSSSM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129947001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

How to utilize these unstructured data effectively is a challenging topic. In the background of A share T+0 and stock option promoting in the China security market, we present a model to recognize the risk and investment opportunity according to the massive online financial textual information. Since the key word vector is in extremely high dimension space and critical in influencing the performance of our forecast models, a manifold learning method is firstly applied to reduce its dimension while keeping essential features. By utilizing financial event study, we secondly apply support vector machines to predict the news type and sentiment value. The model can achieve the intelligent and instant match between textual news and the reactions of stock market. Our results provide prompt supports for financial practitioners to make investment decisions no matter they are in long or in short positions in the market.","PeriodicalId":211783,"journal":{"name":"2015 12th International Conference on Service Systems and Service Management (ICSSSM)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129277232","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly, the paper reviews some former studies about inflation forecasting and predicting methodology, finding that SVM is a nonlinear adaptive data-driven model with strong approximation and generalization ability, which can be applied to complex forecasting tasks. Secondly, the paper establishes a SVM model and discusses the selection of kernel functions. Thirdly, the Particle Swarm Optimization (PSO) and the Genetic Algorithm (GA) are introduced to optimize the models. Then the SVM-based models (Fixed-SVM, PSO-SVM, GA-SVM) together with a BP neural network are employed to forecast Chinese inflation rate. The results show that the PSO-SVM performs better than BP and any other SVM-based model since its MSE of testing group is 0.006 and its absolute errors between predictions and real values are all below 0.02. It reveals that the final PSO-SVM model is promising in short-term inflation forecast.","PeriodicalId":211783,"journal":{"name":"2015 12th International Conference on Service Systems and Service Management (ICSSSM)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126109185","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The occlusion is generally endowed a little weight to weaken its influence on recognition performance. On the basis of this idea, many existing algorithms used the reconstruction error or projection error as the probability estimation for occlusion image. These methods require iterative computation, which may lead to the difficulty of threshold selection and high time complexity. To solve these problems, this paper proposed a novel method for occlusion face recognition by using an error detection method. First, a face image is divided into four regions and we extract feature and detect error for each region. Second, we use the logarithmic transform error operator to calculate the weight value of each region. The experiments based on the AR database demonstrate that the proposed algorithm for occlusion face recognition achieves high efficiency and good robustness and outperforms the existing methods for certain occlusion recognition.","PeriodicalId":211783,"journal":{"name":"2015 12th International Conference on Service Systems and Service Management (ICSSSM)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122639334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
