{"title":"The Study on the Optimization Model for Producing Olefin by Coupling Reaction of Ethanol Based on Clustering Analysis and Multiple Regression","authors":"Xingzou Liu, Siyuan Shang, Xinyu Zhao, Liguo Fang","doi":"10.1145/3547578.3547580","DOIUrl":"https://doi.org/10.1145/3547578.3547580","url":null,"abstract":"As a basic chemical raw material, olefins play a very important role in optimizing product structure and promoting economic development. In recent years, the olefin industry has faced unfavorable external environmental challenges such as low oil prices and the spread of the epidemic, and the uncertainty of industry development has greatly increased. Due to the huge demand, technological innovation in olefin production has become a top priority. Ethanol, which is the feedstock for C4 olefins, has an impact on the selectivity and yield of C4 olefins under different catalyst combinations and temperatures. Therefore, the study of ethanol-coupled preparation of C4 olefins under different conditios is conducive to improving the synthesis efficiency of C4 olefins and providing decision-making suggestions for the optimization and nconfiguration of chemicals. In this paper, 120 sets of experimental data are analyzed and processed, which provides a universal calculation step and solution for the parameter selection of ethanol-coupled to prepare C4 olefins under specific conditions. First, the by-product relationship was determined by cluster analysis in order to analyze the factors affecting ethanol utilization and C4 yield. Then, using multiple linear regression and partial least squares regression, the quantitative relationship between the variables was found, and the yield of C4 olefins at a temperature of 400 degrees, catalyst quality of 200 mg Co/SiO2-200 mg HAP, Co support of 1.1 Wt%, Co/SiO2 concentration of 1.06 wt%, and C4 olefin yield of 1.15 ml/min of ethanol concentration reached a maximum value of 77.21%. Finally, after error analysis and validity test, it is concluded that it is suitable for chemical reactions in most industrial production and can be used for efficient extraction of the target product in actual production. In the future, it will be optimized in a larger amount of experimental data, further optimized in combination with deep learning, to improve accuracy and accuracy.","PeriodicalId":381600,"journal":{"name":"Proceedings of the 14th International Conference on Computer Modeling and Simulation","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133926041","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}

Traditionally, cranes are modeled as multi-freedom robots and use robot path planning algorithms to plan path in continuous space. However, the paths planned by these methods are not smooth enough to operate. In addition, presently, most of proposed lifting path planning algorithms focus on static environments, requiring accurate environmental information to build maps, which is too computation expensive to meet the requirement of real-time path planning. In this paper, we propose a deep reinforcement learning-based lifting path planning algorithm for hybrid action spaces. The network structure is developed based on TD3. A new reward function is designed and hindsight experience replay is used to solve the reward sparsity problem in long distance path planning. The planning path is smooth and can achieve real-time path planning in unknown environments. The result of simulation experiments demonstrates the effectiveness of the proposed approach.","PeriodicalId":381600,"journal":{"name":"Proceedings of the 14th International Conference on Computer Modeling and Simulation","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121272205","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}

Different data format and coding of the data sources requires extract, transfer, load, or ETL operations to enterprise data warehouses. Fact and dimension tables are main data structures in typical data warehouses. A typical fact table relates to several dimension tables, one of which is a time dimension. A fact instance is based on a point in time. The time granularity depends on the users’ requirements. Dimension tables comprises several attributes, some of which may be time varying over periods of time. These dimensions with time-varying attributes are called slowly changing dimensions (SCD). SCD may cause incorrect analytic problems. Known proposed solutions still have deficiencies. This paper presents a temporal data warehouse. It is a data warehouse which allows multiple temporal attributes for each time varying dimension and solve the SCD-related problems. The proposed design can be implemented by using temporal relational database technology which is currently a part of the SQL standard. Thus, improves productivity, reduces development time, and ease application maintenance. Key temporal data warehouse operations using the temporal features of SQL:2011 are demonstrated.","PeriodicalId":381600,"journal":{"name":"Proceedings of the 14th International Conference on Computer Modeling and Simulation","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127290823","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}

Combined with the experiments, it is concluded that the stronger the inter-layer coupling, the shorter the information propagation period, the faster the peak and the higher the peak; when the inter-layer coupling is weak, the information propagation is fastest when the source is in the platform layer, and the period is smallest and the peak is highest when it is in the media layer.

In this paper, we model portfolio of bitcoin and gold based on the price trend data of bitcoin and gold in the last five years. After predicting the trading price trend, we build a psychological expectation investment model to quantify the investors' psychological expectations and get an investment plan with both return and protection.

An analysis model integrating multiple indexes, including essential operation, time, environment and safety was proposed using the benefit-cost analysis (BCA) method. A case study was carried out according to the actual data of the Beijing-Shanghai Expressway, comparing the diesel-driven and electric-driven self-driving freight lines with the conventional transportation scheme. The analysis result indicates that the diesel-driven self-driving freight line has obvious benefits compared with the conventional scheme. Still, the electric-driven self-driving freight line reflects increased cost on the contrary, which is limited by the current battery technology level.","PeriodicalId":381600,"journal":{"name":"Proceedings of the 14th International Conference on Computer Modeling and Simulation","volume":"1 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125761679","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 three-dimensional coordinates of the missile in the UCAV body coordinate system and the number of remaining decoys are taken as the input states. The joystick, throttle stick control stroke and the decoy launching pulse are taken as the output actions. The dense reward composed of relative situational parameters and flight parameters and the sparse reward constituted by the result of the decoy interference and the result of the engagement are designed. The soft actor critic (SAC) algorithm is improved to adapt to the action space of mixed continuous action and discrete action, and finally the end-to-end UCAV escape maneuver policy and decoy launching policy from state input to control output is obtained. Through simulation verification, the escape rates of the UCAV with and without the decoys are compared, and the results show that the escape rate with escape maneuver policy realized by the agent can reach 59.0%, and the escape rate combined with the decoy launching policy will increase by 6.7%, finally the UCAV escape rate can reach 65.7%.","PeriodicalId":381600,"journal":{"name":"Proceedings of the 14th International Conference on Computer Modeling and Simulation","volume":"151 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127762354","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 multi-objective optimization method based on evolutionary algorithm is devoted to improving the performance of multi-objective optimization and dealing with uncertainty disturbance, which is very suitable for the related problems to be studied in this paper. In this paper, a new multi-objective evolutionary optimization method is proposed for multi-objective optimization problems with uncertainty in decision space, which aims to find a set of robust optimal solutions and achieve the optimal balance between optimality and robustness. The proposed algorithm uses the idea of multi-tasking and knowledge transfer and uses one population to solve two optimization problems. In this paper, a vector archive updating strategy based on memory mechanism is proposed to maintain the robustness and optimality of Pareto solution set, measure the average and worst case of solutions under different disturbance degrees, and evaluate each solution comprehensively. Experiments show that the proposed robust multi-objective optimization method can obtain a set of robust Pareto optimal solutions in the presence of disturbances, and its robust performance is better than other algorithms in most test problems.","PeriodicalId":381600,"journal":{"name":"Proceedings of the 14th International Conference on Computer Modeling and Simulation","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130123114","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}
