The industry focuses on quality assurance processes. ABCtronics’ plant is facing the problem of downtime which is a matter of concern for semiconductor companies. By observation, the pattern follows Gamma distribution. Thus, the ion-implanter of the IC chips ought to be replaced. After calculations of Beta Distribution are done, it shows that the company’s original fabrication process is in good shape. The QRT has proposed a quality control policy Chip Testing Method (ICTM) to replace the existing policy Individual Lot Acceptance Testing Method (LATM). There are two types of distributions chosen, Hypergeometric and Beta Distribution. Both shows that the new manufacturing technology adopted by ICTM can effectively improve the accepted rate of chips. From observing our data, we know that the time before IC chip failure (in years) is exponentially distributed. There is a very high chance that ABCtronics will meet the expectations of PQRsystems for having a product lifetime of 6 years or higher. Multiple linear regression model has better explanatory power. We consider the industry overall is experiencing a medium level demand.","PeriodicalId":230625,"journal":{"name":"2021 International Conference on Computer, Blockchain and Financial Development (CBFD)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128441395","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}

Therefore, traffic congestion is becoming a major problem in cities around the world. These phenomena not only waste residents’ time and money, but also cause serious pollution to the environment. Therefore, traffic congestion monitoring is of great significance for analyzing the problem of traffic flow stability. To improve the prediction accuracy of urban road traffic congestion, this paper proposes a conges-tion discrimination model based on Pattern Mining according to relevant res. Then we combine a lot of data for data mining. Given the urban road traffic congestion real-time identification problem, we extract some key factors.

However, the uncertain volatility in the market is a drag to construct a certain portfolio. Based on several blue-chip stocks from S&P, this paper aims at constructing an optimal portfolio with risky assets. The autoregressive moving average (ARMA) model and the Mean-Variance model are selected for investigations. Specifically, the paper builds time series models and forecasts the future returns with a rolling window based on the ARMA model. Then, the predicted weekly returns are used to calculate the Efficient Frontier (EF) of every single period using Monte Carlo simulation. Furthermore, the optimal point with the highest Sharpe Ratio locates the upper-left area of the EF is adopted to set up and adjust the portfolio of each period. The back-test results show that the portfolio performed well compared to the S&P500 index. On top of that, the ARMA model selected performed well in predicting the future return of targeted stocks. Moreover, the Mean-Variance Model, abbreviated as MV model afterward, with maximized Sharpe ratio, also generates agreeable results. Specifically, the weight on new advanced industrial stocks and retail stocks are relatively high in the portfolio. This empirical process further proves two important facts in financial markets. (1) It is feasible to forecast future stock by returns in the past; (2) it is advisable to pay more attention to new advanced industrial stocks and retail stocks. Adding these kinds of stocks into the portfolio is more potential to gain high returns with correspondingly low volatility.","PeriodicalId":230625,"journal":{"name":"2021 International Conference on Computer, Blockchain and Financial Development (CBFD)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133994989","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 results show that digital finance can promote the innovation of private enterprises, and the conclusion is still valid after controlling endogenous and replacing variable indicators. Further research finds that digital finance can promote the innovative development of private enterprises on the GEM by alleviating the financing constraints. In addition, the influence of digital finance on the innovation of private enterprises has significant regional heterogeneity, and the promoting effect is stronger in the developed eastern regions. This study enriches the relevant research on the impact of digital finance on enterprise innovation, and concludes that the government should increase its support for private enterprises, establish and improve the risk control mechanism of digital finance, and coordinate the regional development of digital finance.","PeriodicalId":230625,"journal":{"name":"2021 International Conference on Computer, Blockchain and Financial Development (CBFD)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133776817","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}
