Management direction to delivery maximum value for customer is in all valid management's conceptions. Porter described supply chain conception as instrument which recognize surplus value for customer. Lean's conception as lean production and it's accruement on value for customer. Added value as something more than difference between profits and costs. Utilities kinds in economy. Logistic's value creation: feature's problems.

An integrated supply chain is currently a decisive factor when it comes to remaining on increasingly demanding markets. Optimal organization of the supply chain is often a serious challenge for businesses that need to function in a more efficient way, and to provide products tailored to individual customers’ needs. The accuracy and precision at every stage are crucial, as well as shorter response time to changes in demand, customer tastes and economic conditions.

The purpose of this paper is to present intermodal transport as a part of the companies' supply chain in which rail transport is not a necessity but a value added element. The European Commission stated in its current "White Paper" as follows: "Railway is sometimes seen, particularly as far as freight transport is concerned, as an unattractive means of transport. However, certain examples of some Member States have shown that railway can offer high quality transport services". In fact, rail freight transport has undergone a large transformation in recent years. A growing number of shippers and forwarders have discovered rail transport as an economically viable and environmentally friendly alternative to road transport for the movement of cargoes.

Background: A trend to create groups of enterprises can be observed; whose model of operation makes use of assets of large, small and medium sized companies. It is a higher level of organisational changes. This trend is described as network organisation. It is based on the so called supply chain. The Authors of this paper proposed authors' analysis dynamic configuration of the supply chain and presents an example. The supply chain is a metastructure. It is an intermediate form between a single enterprise (microstructure/microsystem) and the global economy (macrostructure/macrosystem). The metastructure is characterized by a dynamic holarchy of mutually cooperating holons (enterprises). Methods: After a brief discussion of the nature of supply chain (metrastructure) and configuration of metastructures, authors present variable supply chains in the light of morphological analysis and presents an example. Results: The key benefits of this approach are: identifying the characteristics of a supply network and modeling the flow in the entire own supply chain metastructure and possible quick adaptations to new situations. Conclusions: Configuration of a supply chain with the use of a morphological analysis is a basic action, if its goal is to optimally model the flow of goods and implementation of quick adaptation to new situations.

In social studies, the human factor plays the dominant role and is the main topic of these studies. In the technical field the situation is somewhat different. The authors of this study have concentrated on the influence of the human component in reliable supply chains. A supply chain is treated as a complex technical-organizing system whose aim is to produce and supply a product that is readily available for use by the consumer. The aim of the article is to produce a critical analysis of the publications put forward a the ESReDA seminar, which was dedicated to the human component in technical systems as well as the referencing of publications with regards to the human component in supply chains.

Well-organized management of a supply chain involves the control of inventory levels and fast response to the changing customer demands. Enterprises cannot cope with this problem which contributes to the growing stock levels and therefore increases costs. The main goal of the article is to present a simulation approach to the problem of inventory management in a supply chain. The work shows the use of computer simulation techniques in order to emulate a supply chain system and its stochastic behaviour. The procedure for the usage of simulation modelling was described in a case study containing an analysis of an online store. The simulation results are presented using statistical parameters, which means that managers can get not only information concerning the expected value of the parameter looking decision-making, but also statistics to the characteristics of the risk associated with the decision associated with possible uncertainty.

The problem that is taken under consideration in the following article concerns the implementation, use and effectiveness of virtual work in the supply chain in e-economy. Any solution concerning employee mobility or the use of mobile technology are due to growing market competition and constant search for new solutions that may enable the companies in the supply chain to be more efficient than their competition. In the supply chain the e-business creates for the companies new challenges they have to face. One of the possibilities to improve your business in the supply chain is to use virtual work. The new challenge facing the e-economy needs to be met. The aim of the article is to refer the virtual work that is used by selected links in the supply chain to meet the e-economy requirements, identify the key factors that characterize e-economy and refer them to the possibilities and benefits of using virtual work in the supply chain.

The fundamental problem concerning development of supply chain strategies is not taking into consideration social and environmental dimensions. Companies and entire supply chains focus on financial issues. External pressures make an issue of Sustainable Supply Chain Management more and more important. Companies start to integrate their efforts to include sustainability in their supply chain strategies. The problem is lack of universal rules and widely accepted metrics of performance. The issue is also very important from a regional point of view because developing regional supply chains can be a threat for the environment and local societies.

Podstawowym problemem w zakresie rozwoju strategii łańcucha dostaw jest nieuwzględnianie wymiaru społecznego i środowiskowego. Firmy i całe łańcuchy dostaw skupiają się w większości przypadków na kwestiach finansowych. Jednak presja zewnętrzna w kwestii zrównoważonego zarządzania łańcuchami dostaw staje się coraz bardziej istotna. Firmy zaczynają integrować swoje wysiłki na rzecz włączenia zrównoważonego rozwoju w swoje strategie w łańcuchach dostaw. Problemem jest brak uniwersalnych reguł i powszechnie przyjętych wskaźników wydajności. Kwestia ta jest również bardzo ważna z regionalnego punktu widzenia, ponieważ rozwój regionalnych łańcuchów dostaw może stanowić zagrożenie dla środowiska i społeczności lokalnych.

Background: Today it is virtually impossible to operate alone on the international level in the logistics business. This promotes the establishment and development of new integrated business entities - logistic operators. However, such cooperation within a supply chain creates also many problems related to the supply chain reliability as well as the optimization of the supplies planning. The aim of this paper was to develop and formulate the mathematical model and algorithms to find the optimum plan of supplies by using economic criterion and the model for the probability evaluating of non-failure operation of supply chain. Methods: The mathematical model and algorithms to find the optimum plan of supplies were developed and formulated by using economic criterion and the model for the probability evaluating of non-failure operation of supply chain. Results and conclusions: The problem of ensuring failure-free performance of goods supply channel analyzed in the paper is characteristic of distributed network systems that make active use of business process outsourcing technologies. The complex planning problem occurring in such systems that requires taking into account the consumer's requirements for failure-free performance in terms of supply volumes and correctness can be reduced to a relatively simple linear programming problem through logical analysis of the structures. The sequence of the operations, which should be taken into account during the process of the supply planning with the supplier's functional reliability, was presented.

The main objective of the text is to try to carry out the analysis with the predominant objective to try and present in realistic way the factors influencing the choice between a service realised only with the use of a road transport and intermodal transport. The author of the analysis put particular stress on the costs of the carriage service, time of its realisation and CO2 emission. The analysis also aimed at showing which of the presented technologies of service providing is more friendly to natural environment. This is due to the fact that the market for intermodal transport and road transport in Poland, knowledge of the mechanisms of price formation and the costs are still low. It is often difficult to determine the unit price of transport modes or mechanisms of shaping them. This results primarily from difficulties with the calculation of the actual cost of transport, terminal operations, management and other issues occurring in road transport and intermodal logistics functions.

The article deals with some phenomena of internationalization of economic and social processes, especially in the context of more and more complex supply processes. They got even more complicated during the pandemic. It was emphasized that a very serious situation forces the use of even unconventional solutions or the search for alternative ways to replace what has been strained by the emerging crisis. In a fairly extensive ending, the prospects for a supply chain strategy have been presented.

Building entrepreneurial companies is associated with taking actions to enable their general development, leading to application of innovative solutions, both in technology and management. Modern economy and pervasive crisis force entrepreneurs to search for alternative means for supporting the progress in order to be able to fight for customers against ‘foreign countries of cheaper production’ and, at the same time, to not being forced to use "drastic" methods of reducing production costs. This paper presents the already existing solutions that are not fully used in Polish reality, which are the network structures (clusters) that have beneficial economic impact and build integrated supply chains. The author is taking a theoretical attempt to connect concept of supply chains and clusters. Consolidation will relieve the individual companies and thereby will create opportunities to take new - common – actions, which together will create entrepreneurial network structure and bring individual benefits.

The article shows that in the context of accelerating the processes of economic integration in aviation logistics at the micro, meso and macro levels, complicating the forms of business organization, the emergence of new forms of cooperation between companies and new ways of jointly creating added value, many organizational boundaries in the economy are becoming more blurred and dynamic. The use of the concept of “ecosystem” in research is growing. An attempt is made to consider the possibility of using the “ecosystem” design for economic analysis at the aggregated level and to highlight the elements of the aviation logistics ecosystem on which the attention of researchers will be focused. From the authors’ point of view, the aviation logistics ecosystem is a combination of aviation, logistics, transport and postal organizations, which provides goods express delivery supply chains with the system of interconnected technologies. In the framework of the article analysis of air cargo industry framework, synchronization and digitization of service operations in air cargo service supply chain, express delivery supply chains were represented. The authors proposed a mathematical model that allows logisticians to optimize the supply chain of special categories of goods, which is one of the priority tasks of the aviation logistics ecosystem.

Background: This paper is devoted to the issue of the spread of disturbances along processes in supply chains. Today, in a turbulent global environment, companies are exposed to an increasing number of internal and external risks. The adverse events may sometimes bring serious negative consequences and cause a domino effect of disruptions in the supply chain. In the context of business continuity and risk management concepts, it is interesting to observe what the direction (up or/and down supply chain) of disruptions and the sequence of disrupted processes is during a crisis situations. Methods: The conducted research was designed twofold. First, a systematic literature review of the domino effect in supply chains was conducted. Here, the desk research method was used. During the second stage, a survey was performed among 202 large manufacturing companies operating in Poland. The quantitative phase of the research used the Computer Assisted Telephone Interview (CATI) method. The sampling mainly used the "Rzeczpospolita" newspaper database “500 List”. Results: Data are gathered in several tables. The results supported the answering of four research questions. These concerned the most seriously disturbed processes in the supply chains of the researched companies in the last three years, the spread of disruptions along supply chain processes, process disruptions affecting clients and suppliers, and types of risks seriously disrupting supply chain processes. The processes were identified using GSCF model. Conclusions: A domino effect of disturbances occurred in 95% of researched supply chains, with each supply chain process having the possibility of becoming its epicentre. However, according to the researched companies, the production process was the most common site of serious disruption in the last three years, and most likely to interfere with other processes. Disturbances spread multidirectional along supply chains. The uncertainty of the external environment is the most problematic to manage, because a macro environment that negatively affected a company was the most common risk, disrupting supply chains and, particularly, supply logistics. Disruptions of purchasing and supplier relationship management affect the processes of suppliers and clients in the most serious way.

Wstęp: Artykuł poświęcony jest zagadnieniu zakłóceń rozchodzących się wzdłuż łańcuchów dostaw. W dzisiejszym turbulentnym otoczeniu, przedsiębiorstwa narażone są na wzrastającą liczbę wewnętrznych i zewnętrznych zagrożeń. Niepożądane zdarzenia mogą być przyczyną poważnych strat w procesach i powodować efekt domina. W kontekście ciągłości działania i zarządzania ryzykiem, interesujące jest zaobserwowanie jaki kierunek mają najczęstsze zakłócenia (w dół czy w górę łańcucha dostaw) oraz jaka jest sekwencja zakłócanych procesów w łańcuchach dostaw w sytuacji kryzysowej. Metody: Badanie zaprojektowano dwukierunkowo. W pierwszej kolejności przeprowadzono analizę literatury przedmiotu dotyczącą problematyki efektu domina w łańcuchach dostaw. Wykorzystano w tym celu metodę analizy źródeł wtórnych. W drugim etapie zrealizowano badanie ankietowe, które objęło 202 dużych przedsiębiorstw produkcyjnych funkcjonujących w Polsce. Operat losowania stanowiła baza największych polskich przedsiębiorstw z tzw. Listy 500 według „Rzeczpospolitej” oraz baza Bisnode. Rezultaty: Zebrane dane zaprezentowane zostały w kilku tabelach. Ich analiza pozwoliła odpowiedzieć na postawione pytania badawcze. Zidentyfikowano najpoważniej zakłócane procesy łańcuchów dostaw, kierunek rozchodzenia się zakłóceń, wpływ zakłóceń na procesy klientów i dostawców a także rodzaje ryzyka zaburzające poszczególne procesy najpoważniej. Procesy łańcucha dostaw określono wykorzystując model łańcucha dostaw GSCF. Wnioski: Efekt domina wystąpił w przypadku 95% analizowanych łańcuchów dostaw. Badania pokazują, że każdy proces łańcucha dostaw może stanowić epicentrum negatywnych skutków. Według respondentów, najpoważniejsze zakłócenia w ostatnich trzech latach dotyczyły bezpośrednio procesu produkcji. Zakłócenia te są też najczęściej bezpośrednim źródłem ryzyka dla skutecznego funkcjonowania innych procesów w przedsiębiorstwie. Zakłócenia rozprzestrzeniają się w łańcuchach dostaw wielokierunkowo. Niepewność otoczenia zewnętrznego jest dla firm szczególnie trudna do zarządzania. Zagrożenia pochodzące z makro otoczenia najczęściej bowiem w najpoważniejszy sposób zakłócały procesy badanych przedsiębiorstw, a w szczególności ich logistykę zaopatrzenia. Zakłócenia w zakupach i procesie zarządzania relacjami z dostawcami w najpoważniejszy sposób wpływają na procesy dostawców i klientów.

Often, in the course of doing business companies are forced to make decisions and activities at risk. One of these activities is to initiate cooperation within the supply chain to new entrants. Research shows that the way enabling reduction of this risk is to have appropriate certificates, markings and testimonials. These are factors of great importance for SMEs.
