The intensity of technology development that we have witnessed in recent years has changed the expectations and attitudes of customers, as well as their understanding of value, and is becoming the new leading factor in the development of the industry. A retrospective of industrial production shows that all stages of change and development that it has gone through are stimulated precisely by the desire to meet the demand, expectations and needs of customers. In this sense, industrial enterprises around the world are clearly aware of the need for change. They should review their current production and sales strategies and focus their attention and efforts on building dynamic production models that will allow them to continue to operate successfully in a highly competitive market environment and changing customer requirements. Digitalization plays a key role in this new scenario in which industrial enterprises must fit in today. Digital technologies and the opportunities they create are the main driving force for the necessary radical change, which companies must rely on in order to increase their efficiency and, respectively, to maintain their competitiveness. This publication presents a conceptual model for assessing the digital maturity of the production system of the industrial enterprise.

The paper theoretically substantiates and practically implements mathematical methods of modeling production systems, proves the adequacy of mathematical models and optimization methods, as well as selected rational optimization methods and created software that implements the selected methods in practice. The analysis of methods of modeling and optimization of production technological systems is performed, the most effective methods of solving these problems for discrete production are selected. The main provisions of infinite-valued logic and ordinal determinants, on which the structural-logical approach to the study of complex systems, which include production systems in instrument making, are considered.

The article offers an approach for training of students from qualification degree ‘Master’ in the specialty of ‘Industrial engineering’. It represents analyses of suitable expert systems which are used throughout the process of computer-based designing and diagnostics of mechanical products. We have created a scheme of an expert system for gear transmission designing as well as algorithms based on rules of production for the purpose of investigation of stress concentrators and change of the geometry of segments from a gear or a shaft. We have also rationalized the usage of appropriate methods for engineering analysis and the usage of software products for simulation modeling and investigation of designed objects’ behavior through the use of a Frequency Analysis. The latter also includes searching for collisions that take place during the generation of the designed objects’ assembled unit. The results are useful for the purpose of acquisition of skills and knowledge in the field of expert systems application; they would help in the process of searching for creative solutions within the stages of computer-based designing of technical objects, and in the process of diagnostics of their exploitation.

This paper deals with the safety, modeling, simulation and the possibility of automation of a production warehouse as a key component on CIM systems. The manufacturing has been changed significantly by using information systems. Using electronic data processing in the production systems and beyond, automatic protocols are derived and flow both on confirmation of the order and in economic aspect of the raw material. Also, information systems are used in planning and controlling the production, including machines, equipments and entire production process, as well as a lot more opportunities have been provided for the operator. But, security of the production systems is one of the concerns which are elaborated in this paper. Production systems play an important role in industrial and economic development of a country. Recent years, there was a tremendous change in the technology of production systems. Such changes happened as a result of advances in the field of hardware and software technology, which are directly or indirectly related to modeling and simulation of production systems. In this paper, we will investigate the possibility of automation of a production warehouse as one of the key components of CIM technology. Simulations are new and very attractive area. Nowadays they have become indispensable engineering tools for solving engineering tasks, leaving behind the traditional analytical methods. They include design, analytical and optimisation tasks of complex production systems, computer architecture, biological and military systems etc. This is made possible, because of failure to gain good results by the analytical methods, which is the case also for simple systems too. In the group of traditional methods are distinguished: arrays method (querying theory), different heuristic mathematical methods etc.This paper also deals with modelling and simulation of flexible system for electrical machine assembling by ARENA software.
