With the increase of the number of users, online food ordering platforms are facing more and more challenges and pressures. The efficiency of order processing directly determines the customer satisfaction with the platform and the comprehensive competitiveness of the platform. In this paper, The Genetic Algorithm (GA) is applied to solve the TSP problem to optimize the delivery path of riders, so as to improve the delivery speed of orders. By comparing the efficiency of GA and Dynamic Programming (DP) algorithm in a simulation model of O2O system developed by SUMO, we found that the dynamic programming will not be applicable when the number of TSP nodes is beyond a threshold, i.e., 10 in this case. To improve the efficiency further, multiple genetic algorithms were run in a manner of parallel computing for the distribution strategy of takeout orders, which means that an independent genetic algorithm serves for processing the TSP route of an individual rider.","PeriodicalId":236797,"journal":{"name":"2020 13th International Symposium on Computational Intelligence and Design (ISCID)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125049024","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}

Existing studies have constructed fatigue analysis methods and indicators, but have not analyzed the causes of driver fatigue from the perspective of human factors engineering. This study sorted out the content of drivers' shift work system, and used t-test, one-way ANOVA, Pearson correlation analysis and other statistical analysis methods to analyze the correlation between drivers' sleep and fatigue according to their age, working section, technical level and lifestyle type. The results show that the sleep quality of rail transit drivers is significantly worse than that of average adults, and the degree of fatigue is higher, which is mainly reflected in mental fatigue and motivation weakening, and sleep quality has a direct effect on fatigue. Finally, according to the research results, the paper puts forward suggestions for improving the shift work system, which can provide reference for improving the safety level of rail transit operation and optimizing the personnel management strategy.","PeriodicalId":236797,"journal":{"name":"2020 13th International Symposium on Computational Intelligence and Design (ISCID)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127766612","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 deep learning (DL) based noise reduction technique for Raman spectroscopy. The proposed DL network is developed with several training and test sets of noisy Raman spectrum. The proposed technique is applied to denoise and compare the performance with different wavelet noise reduction methods. Output signal-to-noise ratio (SNR), root-mean-square error (RMSE) and mean absolute percentage error (MAPE) are the performance evaluation index. It is shown that output SNR of the proposed noise reduction technology is 10.24 dB greater than that of the wavelet noise reduction method while the RMSE and the MAPE are 292.63 and 10.09, which are much better than the proposed technique.","PeriodicalId":236797,"journal":{"name":"2020 13th International Symposium on Computational Intelligence and Design (ISCID)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127058275","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}
