Industrial companies are linked with affiliated firms, suppliers and customers through the supply chains. Such chains operate within large-scale networks directly related to distribution and warehousing. In order to meet the market demands and customer new expectations, the various components of the supply chains have to be developed i.a. through implementation of the innovative vehicles, green and blue technologies. Moreover, modernization processes of transport and logistics system need to be resistant to crucial mistakes related to innovative solutions implementation in order to exclude domino effect occurrence. The authors attempt to build topology-based approach to the modernization of transport and logistics systems. It is assumed that each innovation application is the independent element-based coalition, possessing linked object structure. The results of multi-year researches demonstrate the offered approach as a useful tool to analyze innovative changes for obsolete transport and logistics system as hybrid structure. The ways of system structure transformation, as well as possible innovative effects are considered. The preliminary results have been obtained for compositions on meso-level for the case of marine propulsion modernisation. The paper is illustrated by various examples.

In The Beginning

The main topic of the submitted paper is intelligent logistics and its integration into production systems. In the beginning, the problem that lies in the inadequate knowledge of the internal state has been defined. The new society-wide trends that will originate in a few years are also outlined. Those trends will affect factories and their logistics systems on a large scale. Therefore, it is necessary to have a strategy that takes these new trends into consideration. In this manuscript, is described a strategy for intelligent production systems, as well as technologies for different types of production-logistic strategies. Many of these technologies can be applied together with the Digital Twin. The Digital Twin is a new concept in the field of designing production and logistics systems in the factory. Finally, we provide a description of the implementation of the Digital Twin into the production and logistics system.

The article discusses the development of transport and logistics systems based on integrated digital platforms, discusses the logistics of sustainable development based on the use of modern digital technologies. The article analyzes modern global initiatives in the field of “green” logistics, which have a significant impact on the efficiency and competitiveness of supply chains. Digital platforms that play a key role as system integrators of sustainable development in logistics are studied, and a forecast of their use in the EEU space is provided. A model of an integrated transport and logistics system based on interaction, competition, collaboration and cooperation has been formed.

The Difference

The article considers the need to develop the transport and logistics system of Ukraine, identifies the importance of transport and logistics infrastructure of the country for its geopolitical position and socio-economic development, the role of transport retrospectively, demonstrates the close relationship between transport innovation and change in geospace and geopolitics. The relevance of Gartland's theory of G. Mackinder and «land-sea» dichometry is confirmed, which determines the difference of resource potential of territories, their geography and, accordingly, features of transport and logistics systems that can be created in these territories. The possibilities of the transport and logistics system as the main leader and consolidator of the goals and objectives of globalization, glocation and the concept of sustainable development are determined. It is proved that transport and logistics systems are an important factor in stable and dynamic development of the country's economy, can positively affect living standards through employment, environmental protection, innovative tools, training, etc., is a successful prerequisite for integration into the world political and economic space. The analysis of the level of logistics development in Ukraine on the basis of the logistics efficiency index allowed, despite a certain subjective nature of the methodology for calculating the indicator to identify urgent problems of transport and logistics infrastructure and ways to improve its level. The relevance and significance of the study is to identify areas for improvement of the transport and logistics system of Ukraine for socio-economic development and its full and effective integration into the network of international transport corridors through the development of transport and logistics infrastructure in the region. The need for state support of the transport and logistics system as a subsystem of the national economy through the creation and regulation of a favorable investment and innovation field, by developing a strategy and concept for the development of national transport and logistics infrastructure, large-scale programs for their financing.

Abstract Top-down attention, controlled by frontal cortical areas, is a key component of cognitive operations. How different neurotransmitters and neuromodulators flexibly change the cellular and network interactions with attention demands remains poorly understood. While acetylcholine and dopamine are critically involved, glutamatergic receptors have been proposed to play important roles. To understand their contribution to attentional signals, we investigated how ionotropic glutamatergic receptors in the frontal eye field (FEF) of male macaques contribute to neuronal excitability and attentional control signals in different cell types. Broad-spiking and narrow-spiking cells both required N-methyl-D-aspartic acid and α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor activation for normal excitability, thereby affecting ongoing or stimulus-driven activity. However, attentional control signals were not dependent on either glutamatergic receptor type in broad- or narrow-spiking cells. A further subdivision of cell types into different functional types using cluster-analysis based on spike waveforms and spiking characteristics did not change the conclusions. This can be explained by a model where local blockade of specific ionotropic receptors is compensated by cell embedding in large-scale networks. It sets the glutamatergic system apart from the cholinergic system in FEF and demonstrates that a reduction in excitability is not sufficient to induce a reduction in attentional control signals.

The Relationship

AbstractThe relationship between a firm and its supply chain has been well studied, however, the association between the position of firms in complex supply chain networks and their performance has not been adequately investigated. This is primarily due to insufficient availability of empirical data on large-scale networks. To addresses this gap in the literature, we investigate the relationship between embeddedness patterns of individual firms in a supply network and their performance using empirical data from the automotive industry. In this study, we devise three measures that characterize the embeddedness of individual firms in a supply network. These are namely: centrality, tier position, and triads. Our findings caution us that centrality impacts individual performance through a diminishing returns relationship. The second measure, tier position, allows us to investigate the concept of tiers in supply networks because we find that as networks emerge, the boundaries between tiers become unclear. Performance of suppliers degrade as they move away from the focal firm (i.e., Toyota). The final measure, triads, investigates the effect of buying and selling to firms that supply the same customer, portraying the level of competition and cooperation in a supplier’s network. We find that increased coopetition (i.e., cooperative competition) is a performance enhancer, however, excessive complexity resulting from being involved in both upstream and downstream coopetition results in diminishing performance. These original insights help understand the drivers of firm performance from a network perspective and provide a basis for further research.
