OpisLogistics 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.

OpisThe 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.

OpisDue to stricter CO2 emission limits, new competitors and imminent driving bans, electromobility has registered high growth rates in Austria. The rising number of electric vehicles not only has an impact on automobile production and its suppliers, but also on the after-sales business with the focus on the repair market. In order to meet these requirements, automotive workshops have to redesign and realign their organizational structures and they have to compensate their decreasing service-revenues. Electromobility requires additional qualification and training of employees and the expansion of technical equipment. Small workshops especially are facing this challenge. In order to obtain an answer to the current status of service companies, a qualitative study was carried out and the status was determined based on expert interviews. Recommendations for action can be derived as a result and it can be shown that there is a big difference between the independent and authorised workshops.

OpisThe paper presents the conceptual design of a database for the European Portal of Logistics Services (EPLOS) and its application. The database contains the data on logistics companies, the infrastructure for road, railway, inland, and air transport, as well as the data on the nodal elements of logistics infrastructure (warehouse facilities, seaports, transhipment terminals). Complete and verified information is the fundamental condition for rational decisions about the realization of logistics processes on a meso- and macroeconomic scale. Authors present the relations in the making of the EPLOS database, its assumed scope, and the potential benefits for the TSL market from accessing the EPLOS database.

OpisSmart devices and the corresponding new technologies have established themselves within our society. Since the release of the smartphone game Pokémon Go, the field of augmented reality (AR) - the enrichment of reality with information, realized by smart devices such as tablets, data glasses or smartphones - has been experiencing an upswing. Additionally, the industry is starting to integrate AR applications to increase efficiency. In this respect, HR managers play a key role in the implementation of such technology. They maintain direct contact with employees, have an overview of the entire company and thus are often responsible for change processes. The paper analyses the potential of AR within a company from a personalist’s point of view and discusses critical factors both in theory and practice. The paper validates the technological possibilities and shows results from a qualitative analysis from focus group discussions. The qualitative acceptance model displays factors influencing the implementation of AR.

OpisProduction lines can be designed by an analytical, semi-analytical, or numerical approach. This paper gives a brief introduction to the analytical approach of a single buffer line, the aggregation method, and the analytical approach of a multi-buffer line. An automotive paint shop production system will be used as a figurative example to compare the aggregation method and the recently developed analytical approach for a multi-buffer line. A discussion at the end will show the advantages and disadvantages of the analytical approach.

OpisWe are on the threshold of a technological revolution that fundamentally changes the way we live, work and communicate with each other. To some extent, scale and complexity, this transformation will be as fundamental to humanity as no other technological change in the past. We do not know how it will evolve, but one thing is clear: the response to it must be integrated and comprehensive, involving all stakeholders on a global basis, from the public to the private sector, to the academic community and to civil society. In the context of sustainable and efficient construction, traditional material bases such as wood are becoming increasingly prevalent and implemented in modern design processes and design solutions. The great potential of this building material is achieved due to developments in production as well as the actual construction of timber buildings. Possible ways of production and construction of wooden buildings are diverse. Especially through prefabricated and solid wood products, which are also cross-glued laminated timber products, modern timber construction represents an interesting and sustainable construction technology. The aim of this paper is to define the basic aspects of industrial building industry in the context of new trends and to introduce the possibilities of implementation of elements of industry 4.0 in the field of wood-based construction.

OpisAs already known, no proper control or process control parameter which absolutely guarantees a high level quality of joints made by electro-resistive welding has been established so far, especially when all possible parameters are taken into account during the welding process. Due to the process of butt-welding being very short-lived, ensuring quality of the joints is a difficult and under-researched problem. The application of non-destructive testing methods to the control interface joints is also not reliable. Therefore, further research in this area should concentrate on studying the influence of basic welding parameters, and calculating their direct or indirect impact can serve to achieve a highquality welded joint with for practice sufficient accuracy.

OpisPublic transport plays an increasingly important role in satisfying the transport needs. Travellers’ requirements regarding the quality of services are increasing. In addition to passenger comfort, other parameters are important (timetable and the state of transport infrastructure). Therefore, methods that determine the appropriate organization of public transport for an area should be sought. The purpose of the article is to present the most commonly used optimization methods and tools that have been applied to the chosen problems of organization of public transport mainly in Poland (described in the articles of mainly Polish scientists), but against the background of global research. The article characterizes the functioning of public transport in Poland. The selected problems of public transport functioning, which can be solved by using optimization methods and tools were discussed. The chosen methods that were used to formulate and solve the identified problems were indicated. The effects of this article will form part of the work on the POIR.01.01.01-00-0970/17-00 project "IT system for computer-aided public transport planning" financed by the National Centre for Research and Development.

OpisThis research aims to investigate the benefits of implementing the cloud computing system over the currently used IT system, as well the challenges of applying Cloud computing that companies in Egypt could face. This research applies mixed methods of research. Both qualitative and quantitative methods of research are used in the form of semi-structured interviews and questionnaires, respectively. The semi-structured interview was targeting the supply chain and IT managers of three different companies at Coca Cola Egypt, Nestle Egypt and Carrefour Egypt. A SWOT analysis was conducted to serve as a guide to many companies in Egypt that are willing to implement such a system and can then avoid the weakness points and the threats that they could be faced with during the implementation. The importance of this research adds to the literature by focusing on the application of IOT in Egypt in terms of the implementation of a cloud computing system in Egypt and it analyzes whether it could increase the efficiency of the companies in Egypt.
