To achieve dynamic adjustment of the logistics network's route structure, including the closure or development of new routes, the aim is to minimize the number of routes affected by changes in cargo volume before and after the closure of DC9, while maintaining a balanced workload among the routes. Therefore, an Ant Colony Optimization (ACO) algorithm model is established, and MATLAB and SPSSPRO are utilized to solve the prepared table based on the ACO model. The obtained routes DC69→DC5, DC69→DC8, DC69→DC14, and DC69→DC62 have a cargo conformity rate of 97%, with an average route workload of around 7%. The remaining cargo across all routes is 11,280.7. This indicates that the overall results remain unaffected after deleting DC9 and adding the new route DC3→DC1, with no routes exceeding the required conformity, satisfying the practical requirements. Next, an evaluation is conducted to assess the importance of different logistics sites and routes within the network. Taking into account basic conditions, such as parcel quantities, transport frequencies, maximum transport capacities, transfer capacities, and other influencing factors, a TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution) analysis model is constructed. The processed table is used to analyze the network's robustness, determining appropriate settings for processing and transport capacities. The objective is to reduce the overall operating costs of the network while ensuring a more balanced distribution of network workload.","PeriodicalId":32534,"journal":{"name":"Journal of Electronics and Information Science","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135497339","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, due to its complex access structure, distributed database system naturally has a high demand for query optimization. This paper proposes a high-performance data processing method between distributed database and multi-core processors based on PSO (Particle Swarm Optimization) to solve the task scheduling problem between multi-core processors. Inertia weight is introduced, which is added to the speed of particle flight to adjust the global and local search ability of stationary particles. The research results show that this method reduces the error rate of database query, and the overall performance of database query method is better. The improved PSO algorithm improves the searching ability of particles by dynamically adjusting the inertia weight. Therefore, the improved PSO is a high-performance algorithm to solve the real-time task scheduling problem of multi-core processors.","PeriodicalId":32534,"journal":{"name":"Journal of Electronics and Information Science","volume":"177 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134981113","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}

A country with mature BD has a future, and many enterprises cannot compete without BD. For example, BD can accurately position people's hobbies, the sales industry or service industry can use BD for precision marketing, and the development trend of BD includes data resource, data science, and the establishment of data alliances. Data science is a specialized discipline, a discipline born in the era of BD. It is at the intersection of statistics, machine learning and domain knowledge, and is an obvious interdisciplinary discipline. With the development of BD, data science must also develop with it. How data science develops and in which scenarios it can be applied remains to be studied. Through the research on BD and its development trend, and the theoretical research and analysis of data science, this paper aims to explore the specific application of data science, a new discipline, and practice it. Experiments have shown that applying data science to filtering spam and malware has a filtering rate of up to 95%. When applied to the sales industry, the predicted results are almost identical to the actual results. It has been confirmed that data science can collect, process, analyze data, and make predictive inferences. Data science can be applied to personalized content, navigation, and other scenarios that require prediction of results.","PeriodicalId":32534,"journal":{"name":"Journal of Electronics and Information Science","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135496384","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}
