The main goal of our research is to analyze and display causes of a bullwhip effect formation within a supply chain, as well as to provide the appropriate solutions to limit the occurrence of the bullwhip effect by using the proper information flow and partners’ cooperation within the supply chain. The bullwhip effect is one of the most important issues in the supply chain management and it is present in many companies. It preserves a character of invisibility because there are lots of causes for its formation and they are usually difficult to discern. The bullwhip effect is a phenomenon of an increase in the order variability within a supply chain. The higher we are within the supply chain, the higher is the order variability. The company encountered with the whip effect can successfully reduce its impact by improving the information flow, as well as improving partners’ cooperation within the supply chain. In this way the company can limit its negative repercussions and increase the profit. The article focuses on the overview of the bullwhip effect within a distribution chain, from its causes to suggestions and measures how to ease its negative repercussions on the organisation. Part of the causes could be found in the market demand variability and in the lack of communication about the actual marked demand within the supply chain. The rest of the causes are related to obstacles that emerge among different partners within the supply chain (role of culture). A qualitative analysis is applied on the basis of the selected cognitions from the supply chain management. The quantitative analysis is based on the theoretical research of the effective flow of information among the participants and its contribution to the reduction of the bullwhip impact. The article discusses two research questions: 1) The correct information flow within the supply chain and the improvement of the communication among partners can lead to the bullwhip effect reduction, and 2) A reduction of the bullwhip influence can lead to the increase of cooperation among partners. The results of the analysis can be used for further research.
The article analyzes possibilities of alternative routes of logistics chains between China and Europe. The new routes should shorten up the transportation time and alleviate the current flows through the big European ports, nevertheless, simultaneously, ensure to preserve other qualitative as well as economic parameters.

Logistics is defined as an interdisciplinary science, which deals with coordination, harmonization, connection and optimization of material, product and service flows including flows of information and finance. The main aim of logistics is to satisfy needs of the customer with importance of quality aspect and optimal costs. The paper is focused on practical logistic problems within the company, its suppliers and customers so overall supply chain is analyzed there. The aim of the paper is to provide practical simulation and calculation of selected logistic examples such as procurement, storage and distribution on case studies. These logistic aspects are analyzed in way, how are they explained to students in university educational process on school subjects that deal with logistics in some case. The simulation of storage process is done with specialized software called Byron, which is also used for educational purposes.

The development of the transport sector is a long-term and continual process. This leads to a gradual increase in economic performance, economic growth and a deeper integration of the EU countries into the global economic structures. This contribution is focused on the problem of usage of the east – west corridors for the freight transport in transit. There are proposed for the new transport connections between China and Europe. The aim of the new connections is speed up of transport process of good flows. When proposing new corridor routes and new options for interconnection of the European rail network, basic deterministic methods of network analysis - the critical path method of the CPM and the CCM critical chain can be used. The aim is also to offer new options for development of rail transportation.
Small and Medium Enterprises (SME‟s) was proven to increase the country economic condition due to its capability to retain the product and capital flow stay inside. SME‟s tend to be more creative than the large and traditional enterprises, though the profitability may vary across segment. The rise of technology has brought the customer to be more educated related to product due the ease of information dissemination. Web 2.0 was the basic of today’s social media communication in the context of logistics, enabling the society to directly interconnected one to another. Based on this reason, this study proposed an alternative to understand the SME’s owner in adopting the use of social media for business and logistics purposes including marketing, sales, product announcement, etc. This study involved 53 respondent around south east Kalimantan. The data was analyzed by using GSCA analysis due to its ability to explore the effect amongst variable while ensuring the consistencies. The results present that all exogenous variables show a positive and significant effect, though the only variable showing non-significant effect is the performance expectancies. The greatest effect is shown by the social factor on attitude towards the social commerce.
