Following the events related to the pandemic and the war in Ukraine, increasing air traffic also increases turnaround agents' activity at airports. Turnaround operations are among the critical activities performed at airports, which must be characterized by punctuality and accuracy of the elementary handling operations. Lack of punctuality in ground handling causes delays in air traffic. On the other hand, a lack of accuracy can also cause disruptions that can turn into aviation incidents. Achieving punctuality and accuracy in aircraft handling is possible by minimizing the resulting disruptions during such handling. The safety management system (SMS) assumes activities to reduce the causes of potential incidents. In the turnaround process, the human factor, the technical aspect, and compliance with existing procedures are significant. The authors have extensively analyzed the disruptions arising during ground handling, learning its causes and effects, which will help avoid adverse events. Occurring disruptions can cause delays in the execution of flight operations but can also cause aviation incidents. Therefore, the authors focused on ground-handling disruptions that can cause adverse aviation incidents. The article presents the interference analysis results as an Ishikawa diagram. Using the FRAM method, an analysis of possible disruptions during the baggage handling process was carried out.

Purpose: The research article is an extension of the concept related to logistics coordination in distribution networks. The concept of logistics coordination extends the flow mechanisms of network governance presented in the literature so far. The aim of the article is to conceptualize logistics coordination as a set of network coordination flow mechanisms that are to strengthen the resilience of the distribution network. Disruptions analysis was used to assess the resilience of the distribution network. Design/methodology/approach: The first stage of the research was to identify the gap in the research on network governance. The assumptions of logistic coordination indicated in the literature research were the basis for the methodology of empirical research. The research was carried out in the distribution network of household appliances/electronics. The resilience of the distribution network to disruptions was assessed. Disruptions and deviations in the implemented processes were identified on the measurement cards. In assessing the resilience of the network, indicators of timeliness, completeness and orders without damage were used. Subsequently, a cause and effect analysis and FMEA were carried out. The conducted research was completed with recommendations for the coordinator of flows in the distribution network. Findings: Recommendations for the coordinator of the household appliances/electronics distribution network include mechanisms for logistics coordination that strengthen the resilience of the network. Other mechanisms that the coordinator is already using have also been identified. Among the identified mechanisms are both proactive and reactive actions. The set of mechanisms, in accordance with the proposed concept of logistics coordination, includes mechanisms focused on flexible resources, redundancy of partners in the network, redundancy of stocks at the material distribution point, extraordinary transport and forecasting for the entire network. Originality/value: The indicated mechanisms, both those used by the coordinator and those proposed to be used to increase the resilience of the distribution network, go beyond the flow mechanisms proposed in network coordination. Thus, it makes sense to extend the flow mechanisms to include logistics coordination in the broadest sense, which aims to synchronise flows, ensure the continuity of the processes carried out and the coherence of the activities of the network nodes.

We are currently dealing with disruptions in supply chains. They come from faulty production systems, in poor organization of distribution processes or are related to external factors, often unseen. Consequently, it is necessary to build resistant chains. This article discusses this topic in the context of the basic types of supply chains, i.e. agile, lean and green. The aim of the study was to assess the types of chains in which the tested production entities are embedded and check if the proposed models of building resilience take this into account. The reason this should be investigated further, is to indicate relationships in areas that are rarely captured in research models. Both quantitative and qualitative methods were used in the work. Interviews were conducted in over seventy subjects and a critical analysis of the literature on model of resilient supply chains was performed. As a result of the work undertaken, it can be concluded, inter alia, that in the economic reality, there are hybrid chains in which the characteristics of pro-saving chains prevail. It was also established that the proposed research models for resilient chains should take into account, to greater extent, accents compatible with the nature of the chains occurring an economic reality. It is also necessary to extend their content to include pro-environmental components. At the same time, it is not unequivocal that the chains with the advantage of agility-related attributes are more resistant than the chains in which the greater concentration is attributed to the attributes of lean or green chains. Determining this requires further research.

In the present conditions, the concept of security takes on a special meaning both in the social and economic aspect. The aim of the work is to indicate the key components affecting safety as well as the areas and elements of improving actions taken in supply chains. Achieving the work goal requires identifying the essence of supply chains and key areas of their security. The paper indicates the key areas affecting the security of supply chains and the elements of improving the actions taken in the management of supply chains. The research method used was the analysis of the literature on the subject of supply chain management and security. In addition, the opinions of specialists and business analysts as well as logistics practitioners were taken into account. One of their key challenges for supply chains, due to their role in the economy, is to ensure continuity and reliability of performed tasks, which is closely related to the concept of security. They relate both to the fulfillment of social needs as well as the goals of economic entities and other organizations. The effects of disruptions may concern both the provision of necessary goods to the population as well as the functioning of the entire economy. Their importance was particularly felt in the functioning of supply chains and individual companies during the disruptions caused by the COVID-19 pandemic, which forced enterprises to make significant and quick decisions in order to minimize them and ensure business continuity. The economic impact of disrupting global supply chains has proven to be very negative for many organizations. Important activities related to possible threats include, among others, the development and implementation of a supply chain risk management strategy and ensuring business continuity, building strong relationships with key suppliers, implementing systems ensuring the visibility of the supply network, and the use of new technologies to reduce the risk associated with operating in unstable business environment, preparation and adaptation to new ways of working to ensure business continuity, analysis of the impact of various elements on the entire supply chain.

Background: Along with the development of Industry 4.0, the concept of Logistics 4.0 is also developing in parallel. Some researchers emphasize that the fourth industrial revolution in the area of logistics concerns in particular warehouse services. New technologies related to automatic data identification and autonomous vehicles are increasingly appearing in warehouse processes. In particular, the implementation of autonomous vehicles in processes carried out so far by people generates significant challenges related to the proper preparation of the entire system, but also its coordination with processes carried out in the enterprise. The aim of the article is to present the results of the analysis of disturbances occurring in the first stage of the implementation of autonomous vehicles in the process of feeding material production lines in a surveyed company from the automotive industry. Methods: The article presents the implementation assumptions for the use of autonomous robots in the process of materials feeding. The scope of the required safety analyzes was presented as well as the time measurements carried out regarding the implementation of the process of servicing power supplies for assembly lines. The research used direct observations in the assessed enterprise and unstructured interviews with persons responsible for the implementation. Results: The results show the deviations from the adopted assumptions, both in the area of vehicle safety and the deviations in the time of material supply operations. It is worth noting that both positive and negative deviations from the adopted standard were recorded in the measurements. Based on the analyzes of the causes and effects of the deviations, guidelines have been developed for the changes to the functioning of autonomous vehicles. Conclusions: The results of the presented research allowed to identify potential adverse events that may occur in the process of implementing autonomous solutions in logistics service processes. The basic rules for the implementation of autonomous solutions in logistic operations, which are carried out in anthropotechnical systems, were also indicated.

Intermodal transport networks, as examples of business networks created in supply chains, are differentiated not only due to types of key resources in the organization, but also due to such things as network structure, the nature of the organizations involved, the types of relations they have, and the roles of individual actors in the network. The business network is understood as a dynamic system whose configuration depends on the fulfilment of particular tasks and the competencies of the organizations which form them. Such networks are inherently temporary, because a new task can initiate the creation of completely new inter-organizational bonds or change the type of pre-existing relations between network nodes. The cooperation of enterprises in a freight transport network compels one to look at the problem of knowledge management in a wider context. The paper focuses on the first stage of knowledge management, which is knowledge acquisition in an organization and its environment. The paper presents the idea of gathering knowledge, and identification of the sources of disruptions in an intermodal network.

The resistance of network supply chains to disruptions is the very important exploratory area. Moreover, from the perspective of individual chain links forming a network supply chain, an essential issue is the skill of adapting itself to variable conditions of the environment and changes in the structure of the chain itself. The article took into consideration both of the exploratory areas: the resistance of network supply chains to disruptions and adaptive strategies of chain links in a supply chain.

Due to their growing global and complex nature, supply chains are increasingly vulnerable to natural and man-made disasters that disrupt the flow of goods. Today, recovering from disruptions represents a major challenge for supply chain professionals. In literature, most recovery methods are based on redundancy and flexibility. Their drawbacks are high inventory and coordination costs. The companies analyzed in this paper took another approach: they recovered by collaborating with their network partners, especially by temporarily sharing resources. Based on the relational view theory, this paper aims to describe whether and how companies can gain competitive advantage by relying on collaboration during the recovery process. A multiple case study with companies from the automotive and electronics industries is conducted. Six cases are analyzed with regard to the recovery characteristics and enabler. Seven propositions are derived that give potential for further research on this promising recovery method.

Recent publications from the area of the risk management in the supply chain propose all sorts combinations of determined factors with name of the disruption (strategies of the risk management: mitigating, compensation, diversification ). These strategies aren't appropriate to the strategy of improving the resistance of the supply chain. A concept was indicated in the article of measurement of disruptions in the process of the completion of an order. The identification of disruptions enables to define risk factors in the processes of order : "make to order". The research on the frequency and forces of the influence of disruptions on material flows were conducted in the supply chain of smelting products.
