Sustainable production processes in industrial organizations require the maximal added value with minimal resource utilization. Rational use of energy and energy resources represents an increasing challenge for companies in Serbia and in the world, all with the aim of preserving the environment. Research on material and energy flows, their correlations and the formation of models that are flexible and applicable to different production and service activities, would provide enough information to design processes with resource savings and negative impact on the environment. This paper presents the energy management model for energy profile identification of industrial organizations in the food industry sector. The energy flow was identified in order to have full insight into all energy consumption users.

The importance of the automotive industry is significant in every country and economy. It affects the economic development of the country, and in the last decade, the number of vehicles has been increasing every day, and hundreds and millions of vehicles are now traveling around the world. As a consequence, motor vehicle insurance is one of the most important branches of insurance. In this paper, we consider a general risk management model of motor vehicle insurance that is actually in Serbia. We propose a change of this model and a modification in order to reduce the risk in car insurance, as well as to provide insurance to users with better service, in accordance with characteristics of vehicles. Modification of risk management model is based on the mathematical approach and appropriate data analysis.

The influence of Artificial Intelligence (AI) is spreading up rapidly in many areas of automated industrial systems. As automated industrial systems are becoming more complex, the demand for production without faults is growing and it starts to be a huge issue to solve complex problems with limited human resources and knowledge and within a limited time. The right solution is adopting AI in the process of making decisions in these problems. The potential of AI is growing in different aspects of manufacturing management and control of automated industrial systems. Edge computing on PLC gives the opportunity to put in practice the potential of AI, especially in fault prediction. In this paper are given recent trends in artificial intelligence for automated industrial systems.
Naftna Industrija Srbije j.s.c. has started the transformation from a focused traditional oil and gas company to a broad energy major. This equally applies to all of its vertically integrated businesses including motor fuel retail business in Serbia. Currently, the company is dominating the Serbian motor fuel retail market due to its crude oil refining facilities, own largest network of stations, strong brands, a wide variety of products and services, and familiarity with customer’s preferences. At the same time, the motor fuel retail market started experiencing pressure created by the threads of product substitutes – non-fossil fuels. Customers are increasingly attached to electric vehicles and hybrid electric vehicles, their number is increasing in the Serbian market. Entry into the electric vehicle charging market in Serbia with charging and battery swapping services would be a new strategic initiative of the company creating potential value for its businesses. This strategic initiative perfectly fits the company’s strategy, helps to fulfill its mission and meets the value proposition “drive more miles, enjoy a drive”. The strategic initiative also secures the competitive advantage of the company consisting of a combination of determinants of relatively low costs and differentiation.

Besides higher education activities, there is a complex range of services provided by the educational institutions in Serbia in the field of mechanical engineering. In order to provide a balance between core activities related to higher education and additional activities, in accordance with the national Law on higher education, good organization and synchronization of these activities is crucial. There are many tools and techniques that could be used to make this process more effective and easier. This paper considers the role and importance of standards implementation in educational institutions, especially related to the establishment of quality and laboratory management systems. The similarities, complementarity and differences of standards SRPS ISO 90001:2015 and SRPS ISO/IEC 17025:2017 are examined, together with challenges for their implementation.
