“…Taking into account changes such as globalization, growing environmental dynamics, hyper-competition, supply chain disruptions [6], distribution evolution [7] or information technologies development, and significant progress in science, new paradigms [8], useful in the changing and complex conditions of the operation of modern organizations, are needed. Hence, the authors point to the concept of sustainable manufacturing as the approach that responds to contemporary challenges and follows legal regulations.…”

Sustainable manufacturing involves executing manufacturing processes in a way that follows the sustainable development principles, striving to combine economic, ecologic and social goals. The expected benefits of sustainable manufacturing are a lower cost and an improved environmental impact and well-being of employees. The main goal of the research was to identify barriers to the implementation of sustainable manufacturing principles. Achieving the main goal required the implementation of partial goals: (G1) designing the research tool based on the specific features of sustainable manufacturing identified based on the literature research; (G2) identifying of barriers that limit and/or prevent the implementation of sustainable manufacturing; and (G3) assessing the significance of individual factors limiting (preventing) implementation. The research was conducted in the agricultural transport sector and the subjects of the research were manufacturers of parts and subassemblies for agricultural transport. The ranking of limitations and barriers enables the definition of recommendations for companies willing to implement sustainable manufacturing concepts.

“…Thus, it is a complex problem that occurs in all transport areas [12,13,24,22,27]. According to the literature, the subjects of research are, among others, the efficiency of supplies [11], their reliability [10] or efficiency [28]. Due to the complexity of these problems, decision-making tools play an important role in modern railway traffic organization.…”

Some aspects of heuristic algorithms and their application in decision support tools for freight railway traffic organization. SOME ASPECTS OF HEURISTIC ALGORITHMS AND THEIR APPLICATION IN DECISION SUPPORT TOOLS FOR FREIGHT RAILWAY TRAFFIC ORGANIZATIONSummary. Rail traffic organization is a multifactorial decision-making problem. To achieve the best results and reduce the risk of error when deciding on its implementation, appropriate algorithms should be identified and implemented in the form of computer tools, allowing for the optimal solution to be obtained. This paper discusses the process of organizing freight traffic on the rail network. The algorithm of relocating loaded cars in a compact and dispersed system is discussed. In turn, it is been indicated that the movement of empty and loaded cars must follow a strictly defined timetable. A heuristic algorithm supporting decision-making in the area of rail freight traffic management is presented, divided between the concept development stage, the timetable design stage for the developed concept, and its implementation in the form of specialized tools. An example of how the application works is also presented.

Nash Equilibrium and Stackelberg Approach for Traffic Flow Optimization in Road Transportation Networks—A Case Study of Warsaw

et al. 2023

The article discusses the issue of modelling traffic flows and the transport network. Faced with an increase in the number of vehicles in road networks, the problem of congestion and the need to optimise traffic and adapt the transport infrastructure to changing demand are growing, especially in large cities. With this in mind, the authors of this publication developed a model of the road network in the north-eastern part of the Warsaw agglomeration based on the proposed algorithm. Two methods were used to optimise the distribution of traffic flows: the Nash equilibrium and the Stackelberg approach. The Nash equilibrium assumes the aim of achieving equal average times on all roads for each origin–destination (O-D) pair. This describes the state pursued by a decentralised system guided by the individual benefits of the traffic users. On the contrary, the Stackelberg approach aims to achieve optimal travel times for the entire system. The study was carried out for three scenarios that differed in the assumed traffic demand on the road network. The basic scenario assumed the average hourly traffic demand during the morning peak hour based on traffic measurements. On the other hand, the two alternative scenarios were developed as a 10% variation in traffic volumes from the baseline scenario. On the basis of the results, it was concluded that an increase in traffic volumes for all O-D pairs could result in a decrease in traffic volumes on some links of the road network. This means that the transport network is a complex system and any change in parameters can cause significant and difficult to predict changes. Therefore, the proposed approach is useful in terms of traffic forecasting for road networks under conditions of changing traffic flow volumes. Additionally, the total travel time for the entire system differed for each scenario by a percentage difference of 0.67–1.07% between the optimal solution according to the Nash equilibrium and the Stackelberg approach.
