The paper presents the problem of distribution route planning with dynamic information about sudden customers' needs. Particular attention was paid to dynamic vehicle route planning and its influence on the distance covered by a distribution vehicle. In the article, authors assume that the quick information about customers’ sudden needs is transferred from the EPLOS tool data base. Authors analyze the available literature on transport route optimization and propose a solution to the problem of distribution among customers with sudden needs. In order to present the impact of quick information influence on the distribution route minimization, a simulation model of the vehicle routing problem was generated in the FlexSim environment.

The article presents issues related to database design for problems of planning transport of cargoes by intermodal transport using road and air transport. The main aim of this paper is to develop the structure of the database used in the problems of planning transport of cargoes by intermodal transport. The issue of intermodal transport is a complex decision problem which requires taking into account many technical, economic and qualitative aspects of various modes of transport. The multitude of these aspects contributes to the processing of a large amount of input data used by advanced calculation algorithms developed to determine the optimal routes of cargo transportation. Designing database architecture depends on the number of modules responsible for the final determination of transport plans. It is assumed that the database is responsible not only for collecting input data about air, road infrastructure, processing of information necessary for transport but also for saving results generated by calculation modules. In the article, to understand the problem of the issue, a mathematical model of transporting loads by intermodal transport was included, and for its solution an ant algorithm was proposed. The developed structure of the database with the presented modules is a newly approach in problems of planning transport of cargoes by intermodal transport.

The article defines the database structure used in the issue of the assignment of air transport operators to commissioned transport tasks. The purpose of the work is to develop a database structure that fulfills the function of recording information, presenting results and processing calculated data. Presenting the database in a modular manner is a new concept of data flow management in the problem of the assignment of air transport operators to tasks. The issue of the assignment of air service operators to tasks is a complex optimization problem. The complexity of the database architecture used in the assignment of operators to tasks depends on the number of modules responsible for individual functions implemented in the process of determining the assignment of operators to tasks. In addition, the paper presents a mathematical model of the assignment of operators to tasks, includes basic data entered into the model and collected in the database, describes the assignment restrictions and the criterion function. In order to solve the problem, an optimization algorithm concept has been proposed to solve the analyzed problem. The problem of the assignment has been presented in the multi-criteria aspect.

The article presents the issues of a container train loading at the land intermodal terminal. This issue was considered from the point of view of the distance covered by the loading devices and the duration of loading works, which was influenced by the arrangement of containers on the storage yard and the configuration of pins on the wagons. The conducted research was dictated by the small number of publications on loading an intermodal train, especially from the point of view of pin configuration on wagons. The vast majority of the literature is devoted in this field to marine intermodal terminals, which operating characteristics are different from inland terminals. The importance of this problem resulting from the growing turnover of containers transported by rail transport was also pointed out. The systematic increase of this type of transport and the depletion of the intermodal services' operating capability makes it necessary to improve the train loading process. For the purposes of the research, the issues of containers of various sizes loading onto wagons planning with various pin configurations were presented. A literature review was carried out in the field of train loading methods and strategies. A mathematical model was developed for the decision situation under consideration. The equations defining the most important elements of the considered problem were presented in the general form. This model was implemented in the FlexSim simulation environment. The constructed simulation model was used to develop 12 variants of the approach to an intermodal train loading. The train loading tests were performed both for the random arrangement of containers on the storage yard and for the random arrangement of pins on the wagons. The obtained results made it possible to determine how the knowledge of the arrangement of pins on the wagons influences the planning of train loading and increases the efficiency of loading devices.

Logistics companies are currently differently using IT tools to assist the planning of their operational activity. The functionalities of tools are also different. The paper presents the results of a research on the use of automated solutions to obtain the data necessary for logistics processes planning. It also presents a review of IT solutions used by TSL (transport, shipping, logistics) companies and the functionality of these tools. This allowed for the assessment of the potential of the EPLOS system to be used in TSL companies, as well as the benefits of implementing this system. In the paper, the selected results of a survey made in companies about the crucial data needed for efficient operating were presented. The summary indicates the main features that software should have in the era of the Industry 4.0 revolution.
