One of these methods is to make use of meta-heuristic algorithms in control systems. There are some limitations of using a PID controller as a classical construct. However, it is thought that more successful results will be obtained by optimizing its parameters through meta-heuristic algorithms. Initially, the mathematical model of the vehicle was created in MATLAB/Simulink. Then, genetic algorithms (GA), artificial bee colony (ABC), particle swarm optimization (PSO) and firefly algorithms (FA) were determined respectively as optimization methods. And these optimization methods used to determine the PID control parameters are applied to the developed mathematical model in the MATLAB/Simulink environment. In addition, the performances of the optimization methods are evaluated according to the comparison criteria. As a result of the comparison carried out according to ITAE (Integral Time Absolute Error) fitness criteria, ABC (1.2% - 4.4%) in terms of altitude, FA (4% - 13%) in terms of roll angle, GA (13% - %21) in terms of pitch angle, and PSO (4% - %15) in terms of yaw angle has been more successful than other methods.","PeriodicalId":49443,"journal":{"name":"Tehnicki Vjesnik-Technical Gazette","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78670421","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there is a lack of relevant studies on how to scientifically evaluate the resource integration performance of port enterprises. To comprehensively evaluate the actual effect of port enterprises in process of resource integration, a performance evaluation system of port enterprises resource integration covering 19 secondary indicators from the four dimensions of financial integration, operational efficiency, technological innovation, and realized benefit was built, fuzzy analytic hierarchy process (FAHP) was used to determine weights of various indicators and port enterprises in Zhejiang, Jiangsu, Liaoning, Shandong and Guangdong provinces of China were taken as samples, and fuzzy comprehensive evaluation (FCE) was used to evaluate its resource integration performance. Results show that technological innovation is the primary performance indicator, followed by financial integration indicators, and the impact of realization efficiency and operational efficiency indicators is relatively weak. Resource integration performances of port enterprises in Zhejiang, Jiangsu, Liaoning, Shandong, and Guangdong are generally good. Evaluation results of sample ports reflect the actual integration of ports, and the model can effectively evaluate the performance of port enterprise resource integration. Conclusions obtained from this study provide theoretical support for the scientific performance evaluation of port enterprise resource integration.","PeriodicalId":49443,"journal":{"name":"Tehnicki Vjesnik-Technical Gazette","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81200499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
