Rapid technical progress in technology and its impact on production will put increasing pressure on both its structure and process distinctiveness. In addition to the positive aspects of this revolution, there are also negative ones, leading to a dramatic change in the functioning of individual units in any organization. In order to keep up with the changes, the company must demonstrate a capacity for digitization of its economic activity. This predetermines the purpose of the article, namely to examine the level of digitization of logistics activities in small and medium-sized enterprises in the North-East Region.

Nowadays almost all accounting and production project information are collected into long electronic spreadsheets that are easily accessible for the production managers so they can extract the data and analyze it according to their needs. In every work project, especially in long project production, IT or manufacturing, there is the need to perform an elaborated risk management, just because there is a gap of uncertainty from the process of planning to the final workflow cost. One main task that often causes problems is the quantitative risk analysis. In this article we will show how to use a well-known standard product, that is easily accessible even to micro entrepreneur – Microsoft Office/Excel. With the help of MS-Excel it will be cost effective and easy to extract the data and create standard risk simulations, which will help managers to take decisions and reduce their risk exposition.

Rapid technical progress in the field of industrial and information technology and its impact on ... more Rapid technical progress in the field of industrial and information technology and its impact on production systems will put more and more pressure on both their structure and the distinctive features of this process. The boundaries will become more and more distorted and the structure of production will change substantially. The pursuit of a complex improvement of technological, auxiliary and information activities will increasingly become a major factor in the development of modern production. And this means that on the basis of new communication and computer achievements, nanotechnologies and other technical solutions, the manufacturing structure will change globally. The future production will be considered as a whole, including techniques, technology, and information processes, and functionally integrated manufacturing components such as logistics. The purpose of this report is to analyze the impact of technologies on the stability of integrated logistics information throughout the supply chain.

This is particularly necessary and highly relevant today with the transition from a conventional way of production and successful adjustment to smart manufacturing. Thence, all logistics activities should be designed and organised in such a way that they would comply exactly with the requirements of the smart systems. At present, the information systems of the participants in the logistics chain are for the most part incompatible, which, in turn, creates problems with overcoming the places where these interconnections occur. The purpose of the article is to propose effective solutions for creating conditions necessary to ensure possible interaction and faster performance of this process subject to the requirements of the cyberspace. The integration of the participants in the logistics process on the basis of digitization is one way to create the conditions and the respective possibilities for effectuating an electronic exchange, implementing processing and analysis of mutual information. Basically, these are the essential conditions that apply to the use of digital dimensions in the execution of smart production processes and logistics.

It analyses the characteristics of the business process life cycles and offers a solution on how to make management more efficient and more competitive. It is proved that management of business processes has to be realized to its full cycle, and then identify those of them that can be automated. Means for automated business process management in industrial enterprises are proposed.

The distinctive features of enterprises with such a type of production are becoming increasingly blurred by the growing tendency for global industrial development. They become heavily dependent on the pace of development of automation, industrial technologies, communications and ever more determined by the factors that most affect and shape the trends of that development. It is therefore of utmost importance to carefully define the distinctive features of modern logistics processes that form the foundation of the respective digital development policies, which is also the primary objective of the proposed paper. These policies are undoubtedly enforced by the very evolution of technology and are likely to define the new directions of cyber development.

When designing a modern information system, each organization must anticipate the huge opportunities for constantly increasing the number of automation objects in business processes and expanding the composition of functions and the number of tasks performed by them. Defining the different stages of creating an information system, i.e. the selection of priority tasks has a significant impact on the future development not only of the logistics information system as a whole, but also on its efficient and effective functioning. The purpose of this report is to investigate the development and scope of information logistics under the influence of new technical requirements. On this basis, proposals for the scope of decisions should be made.

Therefore, this new knowledge society will be based on new knowledge generating new products and technologies and new forms of governance in economy, manufacturing, ecology, humanitarian and social processes. This report looks at the possibility of turning knowledge into innovation and innovation into an effective product concept.
