As China's stock market goes through ups and downs, China Securities Regulatory Commission generally adopts a positive strategy. Therefore, to weaken the policy factors, 48 cases of IPO companies dated from January 2014 to February 2014 (before price guidance of 23x P/E ratio ceiling) are selected as samples and an approach of grey relational analysis is adopted to analyze the degree on which different factors are able to have an influence. The results show that in general, internal enterprise value factors are likely to play a more important role when compared with external environmental factors. More specifically, profitability, growth potential, operating efficiency, industry characteristics, solvency, capital scale and structure are factors that are more influencing on the offering price, while the market overview and individual stock overview are ones that play a less important role. Based on these results some policy suggestions with regard to IPO pricing are also offered.","PeriodicalId":425920,"journal":{"name":"2017 International Conference on Grey Systems and Intelligent Services (GSIS)","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115685587","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}

Based on the fresh agricultural supply chain, time limitation and information asymmetry has been considered. In order to improve the experience in the offline store, detailer takes investment, which is based on the hypothesis that investment could bring more guests in a way. The research indicates that the increase of investment could improve the best sales volume and maximum of supply chain profits when influence parameter exceeds the threshold. And when influence parameter stays much lower, the increase of cost is superior to the increase of profits, resulting in the decrease of maximum of supply chain profits, which implies a worse chance to invest a lot.","PeriodicalId":425920,"journal":{"name":"2017 International Conference on Grey Systems and Intelligent Services (GSIS)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116473803","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 host image is processed with one-level of discrete wavelet transform. The low frequency coefficients LL1 can be obtained from mentioned operation, and LL1 is divided into non-overlapping blocks whose size is same as watermarking. Secondly, through the gained coefficients of each block and the given random sequence, grey relational degrees which are preserved as training sample are acquired for each block. The largest singular value which can be found from singular value decomposition for each block is preserved as training target. Thus total training samples and corresponding training targets are obtained. Then, The LS_SVR model can be obtained through the training study. Next, through feeding the trained LS-SVR with the training samples to estimate the largest singular values, watermarking bits are embedded for adjusting the largest singular values. Finally, the watermarking is extracted by the reversing steps, and the extraction algorithm belongs to non-blind watermarking because the original host image is necessary. Experimental results show that the proposed scheme not only possesses good imperceptibility, but also has fine robustness against common signal processing.","PeriodicalId":425920,"journal":{"name":"2017 International Conference on Grey Systems and Intelligent Services (GSIS)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121879996","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}

We divided the period of economic growth of Chinese manufacturing into two stages; 2005–2010 and 2011–2014, and then calculated the contribution rates respectively. The results of both stages are then compared. Findings suggest, the contribution rate of university education to economic growth of Chinese manufacturing is on the rise during the year 2005–2014. This shows that the talent structure of Chinese manufacturing is reasonably increasing and China's traditional economic development pattern of manufacturing is transforming from extensive to intensive.","PeriodicalId":425920,"journal":{"name":"2017 International Conference on Grey Systems and Intelligent Services (GSIS)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116137910","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}

It is very hard or uneconomic to obtain enough failure samples of these equipment in reliability test. Although there are empirical information available, we cannot ignore the inaccurate or uncertainty of these information. In this context, a quantitative analysis model of reliability evaluation for equipment system is put forward in view of the few failure data of equipment life test. The multiple working states of the equipment system and random process of equipment state transition are presented by GERT network. Interval grey number is introduced to describe the uncertainty of the statistical data and experience information of GERT parameters. According to GERT matrix solving algorithm, the system equivalent transfer function can be obtained, and then the reliability evaluation of equipment system can be realized.
