This research was conducted through a survey of 74 construction experts and engineers undertaking different roles in the project (state management agencies, investors, consultants, contractors, etc.). As a result, 29 variables (divided into 06 groups of factors), were established and analysed using Superdecision software. The study shows that option 01 (intersection renovation and expansion) has the highest score; and was proposed to invest and implement in practice.","PeriodicalId":512924,"journal":{"name":"Journal of Transportation Science and Technology","volume":"48 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140526852","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 study proposes a set of 16 criteria based on an extensive analysis of previous studies and inputs from multidisciplinary experts. The criteria reflect the economic, social, and infrastructural challenges characteristic of Ho Chi Minh City, including population density, accessibility, traffic conditions, and flooding. Notably, the criteria set emphasizes the importance of healthcare service provision, human resources, and environmental and social impacts when constructing a new hospital. The research outcome is a hospital site selection criteria set tailored for Ho Chi Minh City, laying the foundation for experts and scientists to apply computational and multi-criteria analysis methods to determine suitable locations. The criteria can also be adapted for areas similar to Ho Chi Minh City.","PeriodicalId":512924,"journal":{"name":"Journal of Transportation Science and Technology","volume":"40 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140525489","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}

Meanwhile, the controller is built using Matlab/Simulink software. The controller and control object communicate with each other using the Modbus TCP/IP protocol with a physical Ethernet link. Besides, the proposed model also fully includes the main turbulence components of the environment affecting the ship that many previous studies on ship trajectory control have ignored.

This study introduces a theoretical framework designed to improve the efficiency of selecting and routing hub islands in an inter-island logistics network by utilizing the hub-and-spoke model. The process of identifying potential hub islands involves an initial assessment of several criteria, encompassing geographical, economic, and equipment-related factors. The utilization of Floyd's algorithm was employed in the computation of the shortest distance matrices between islands, with consideration given to the avoidance of ship collisions. The identification of the required hubs is determined by employing a location set covering model, which includes a constraint on the maximum distance for service provision. The p-Median model was employed to ascertain the most efficient hub locations to minimize transportation expenses. The framework provides a quantitative approach to designing efficient logistics networks for inter-island transportation. It considers important factors, such as shipping routes, hub locations, and collision avoidance. The utilization of this methodology holds promise for augmenting connectivity and streamlining resource accessibility in geographically isolated island areas with limited infrastructure.","PeriodicalId":512924,"journal":{"name":"Journal of Transportation Science and Technology","volume":"6 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140523109","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}

Therefore, this study proposes a fuzzy-logic-based method to model ship collision risks in an area considering human factors. This method utilizes a hierarchical fuzzy system consisting of two fuzzy systems, fuzzy system 1 and fuzzy system 2, which are used to calculate the temporary risks and human factors, respectively. Aggregating the risks from both subsystems produces the overall collision risk index. This approach streamlines on-board risk appraisal, thereby reducing the navigator workload. While the current study delineates the risk modeling methodology, succeeding works validate the framework through simulated experiments. With adequate verification, this hierarchical fuzzy approach can assist next-generation risk-regulated navigation practices and enrich maritime agencies' traffic risk management.","PeriodicalId":512924,"journal":{"name":"Journal of Transportation Science and Technology","volume":"77 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140526457","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 data set used in the study includes 267 experimental samples, each sample includes input factors such as sand amount, aggregate size, water-cement ratio, and aggregate-cement ratio, and the output factor is the permeability of concrete. We applied the Operon model, one of the most effective symbolic regression models based on genetic programming, to construct a function to predict the permeability of previous concrete. This function achieves high accuracy when compared to one of the best black-box models, PSO-XGB.

The manufacturing of non-shrink self-flowing mortar requires the use of many different types of additives. In addition, it is difficult to combine them to meet both technical and economic requirements. This article presents the results of research on producing non-shrink self-flowing dry mortar using fine blast furnace slag with a compressive strength after 28 days of over 80MPa. The input materials were all selected in dry powder form. The water/mortar ratio was 0,13. The fine blast furnace slag contents used were 15%, 20%, and 25%, and the powdered polycarboxylate superplasticizer was used at a content of 0.23% compared to the binder. In practice, the amount of water and superplasticizer must be chosen to maintain stability for the workability of dry mortar. The experimental results on flow, compressive strength, flexural tensile strength, and shrinkage show that the non-shrink self-flowing dry mortar meets the requirements of packaged dry mortar.","PeriodicalId":512924,"journal":{"name":"Journal of Transportation Science and Technology","volume":"67 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140526484","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}
