The methodological basis of the research is classical principles of egalitarianism in the theory of welfare, which allow, based on assessment of the transport and technological infrastructure of the network segment and tariff rates, to build mathematical models that are economically justified, customer-oriented and in demand in management of cargo transportation processes. An algorithm for solving a multi-criteria and multi-extremal problem of integer linear programming with a set of cost objective functions has been developed in the medium of the analytical computing system. The computational experiment is used as a guiding heuristic tool in finding the optimal level of organization and economic efficiency of the cargo transportation process.Optimal combinations of distributions of the number of departure routes per loading stations and related plans of transportation to the reloading stations were found with the help of the Pareto criterion. The obtained values of cost indicators provide the participants of the transportation process with the opportunity to choose competitive options in transportation schemes using small port transshipment stations of the Azov-Black Sea basin.","PeriodicalId":121504,"journal":{"name":"World of Transport and Transportation","volume":"2 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139269386","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 effective design of such systems has a positive impact on the socioeconomic component of any country. The quality of the transport system can be assessed through the population’s access to it. At present, one of the important problems of long-term development of the air transport system of the Russian Federation is definition of a universal indicator that allows assessing access to transport and its possible target standard.The article proposes an approach for assessing access to air travel using mathematical modelling. Two indicators are used as a criterion: a potential number of passengers in the gravitation zones of each airport and a passenger’s time being in the system. A methodology for determining the proposed indicators has been developed. The application of the approach of assessment of access to air travel is demonstrated on the 2019 network.An example of a target (simulated) network of domestic passenger air transportation is also given, which allows to significantly increase access to air travel. Based on the results obtained, the paper proposes target standards for the values of access to air travel for the Russian Federation.","PeriodicalId":121504,"journal":{"name":"World of Transport and Transportation","volume":"8 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139273945","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}

To solve this problem at one of the stages of the industrial process, which is production of road metal, an important material for road construction, it is proposed to develop autonomous power unit based on recuperation of the kinetic energy of dump trucks, namely a unloading and screening unit of crushing and screening plant with non-volatile drive of auxiliary equipment.A non-volatile unloading and screening unit separates the feedstock at the primary stage of production in a non-volatile operating mode, using recovery of the kinetic energy of trucks been unloaded. After loading rubble sandstone into the receiving hopper, the unit activates the process of material segregation into coarse and fine fractions. The respective fractions are fed to the appropriate feeders for subsequent technological processing. The advantage of the unit is the autonomy of the vibrator and feeders’ drives, which helps to raise the efficiency of the process of unloading and separation of the rubble sandstone and reduce energy costs for production of the finished product.The evaluation of the functional capabilities of the non-volatile hydraulic drive of the unloading and screening unit was carried out for hydraulic motors of the screening and conveying equipment. The apron feeder of KM PP-2–10–60B type providing a continuous and uniform supply of feedstock was assumed as the basic equipment, and the volume of working fluid in the hydraulic accumulator supplied by hydraulic jacks was calculated. The results showed that two hydraulic jacks with the specified parameters can provide the required flow and allowed determining the amount of energy stored in the accumulator during feedstock loading. The calculated power of the hydraulic motor allows its use in the feeder. The economic efficiency of the installation with an autonomous drive is estimated considering the mode of operation, the number of shifts and the tariff for electricity.","PeriodicalId":121504,"journal":{"name":"World of Transport and Transportation","volume":"65 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139276466","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 author used the methods of experimental research and survey for obtaining the criteria for assessing the technical condition of spur dikes.Based on the results of the survey of spur dikes, conclusions were drawn about low quality of construction, and the main types of defects were identified both in entire structures and in their elements. Experimental studies on hydrowave models were carried out to assess the beachholding capacity of the spur dikes and their resistance to wave action in the wave basin. It was proposed to divide the spur dikes into separate elements according to the degree of their significance, and the criteria for the technical condition by types of defects for each element of the structure under consideration were obtained.The technical condition criteria obtained from the results of surveys and experimental studies make it possible to assess the technical condition of spur dikes, which will increase railway operation safety.","PeriodicalId":121504,"journal":{"name":"World of Transport and Transportation","volume":"19 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139277769","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}
