Generalized centrifugal force model is selected to simulate the pedestrians passing through bottlenecks. The bottleneck width and the number of pedestrians are considered to measure their impact on the traffic efficiency on the bottleneck. Linear relation between flow and bottleneck width is observed and the number of pedestrians show no significant impact on the flow. With the increasing bottleneck width, the density in the front of the bottleneck entrance decreases. More pedestrians result into higher density in the measurement area. The findings can help researchers have a deeper understanding on the pedestrians’ movement and bring some guidance to design the buildings.","PeriodicalId":397312,"journal":{"name":"Proceedings of the 5th International Conference on Management Engineering, Software Engineering and Service Sciences","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122709545","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}

Using content analysis method, 33 business environment policies promulgated by the central government from 2015 to 2019 will be coded and counted, and will be studied in combination with the business environment report issued by the World Bank. The research shows that China has comprehensively used three different business environment policy tools, and environmental policy tools are the main means to optimize and innovate the business environment. It is suggested that the government should pay more attention to supply-side innovation, pay more attention to taxation and talents, and enhance the implementation of policies and government credit to improve the level of business environment in China.","PeriodicalId":397312,"journal":{"name":"Proceedings of the 5th International Conference on Management Engineering, Software Engineering and Service Sciences","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115360104","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 development of BSP (bus signal priority) system can effectively alleviate the traffic congestion problem and accelerate the construction of new smart city. The BSP system based on GNSS (Global Navigation Satellite System) electronic fence can effectively realize the function of bus signal priority application. It sets the virtual trigger area of traffic signal at traffic junction by using GNSS electronic fence technology, innovatively proposes a trigger judgment algorithm improved by the ray method for the bus entering the intersection electronic fence, and aiming at the problem of packet loss and floating point of bus real – time information, the method of judging the correctness of the electronic fence entry strategy is proposed, which ensures the high accuracy rate of the bus priority system. The system has been formally applied in Nanjing, China. Through the statistical analysis of data from the feedback operating data, bus priority effect is significant. Based on the electronic fence technology, the BSP system can be used in the original urban traffic system software upgrades. It is a more economical, convenient and efficient bus priority solution.","PeriodicalId":397312,"journal":{"name":"Proceedings of the 5th International Conference on Management Engineering, Software Engineering and Service Sciences","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129512675","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}

However, these services have high requirements for network delay and bandwidth. In addition, Facing the future and the \"post epidemic era\", aiming at the problem of multimedia application on the network, If we use the usual unicast communication, it will inevitably lead to a serious waste of bandwidth, and greatly increase the burden of the server, which is obviously a pair of contradictions with precious resources; if we use multicast communication, we can reduce this contradiction. This paper introduces multicast technology firstly. Secondly, it puts forward the multicast idea of campus network multimedia system: deploy IGMP snooping protocol in switching Ethernet, and combine VLAN technology. Thirdly, it provides a framework of multimedia multicast system on the campus based on MVC pattern. Then it describes the designing solution particularly and development method of the difficulty. By experiment, this system has good maintainability and expandability. In the multicast communication mode, the network traffic does not increase with the increase of the traffic, and obtains a good subjective quality evaluation. Audio / video transfers fluency, the flux of network reduces, and has a shorter transmission delay.","PeriodicalId":397312,"journal":{"name":"Proceedings of the 5th International Conference on Management Engineering, Software Engineering and Service Sciences","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131766908","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}

This paper proposes a method of customer demand classification and its importance determination for express service enterprise. First at all, Kano model and K-means clustering were used to objectively classify the customer demands. Secondly, considering the influence of customer satisfaction on the determination of demand importance degrees, classification fitting function was established to correct the initial importance degrees for different customer demand. Finally, Z express company is selected as an empirical study, which proves the rationality and operability of the proposed method in this paper. This method can be further applied to other service-oriented customer demand analysis and has a broad application prospect.","PeriodicalId":397312,"journal":{"name":"Proceedings of the 5th International Conference on Management Engineering, Software Engineering and Service Sciences","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115401282","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}
