Operational Research in Engineering Sciences: Theory and Applications

There is a need for increasing the application of standards that define the way of managing quality, safety at work, risk, and many others. One such organisation is the Serbian Army, a complex centralised system that requires integrating these standards, and often stricter, in all fields of its activities. The current situation in the world, and therefore in Serbia, is sufficient motivation for the project provided by this paper. This project aims to show the integration of risk management systems and occupational safety systems, through the level of protection and exposure of members of the army to the virus infection COVID-19 during the implementation of emergency tasks, by defining risks and proposing additional measures to reduce the level of risk and increase the protection of military personnel.

The methodology shows how a country and relevant institutions should address complexities in the waste management sector. Waste management is a critical issue globally, which heavily impacts the economic development of a country, including the general quality of life within a society. The designed simulation generates different scenarios of the Serbian municipal waste system for reaching the 2035 recycling rate targets. Methodologies such as the theory of constraints, fragility analysis, and systems dynamics were implemented in the model. The scenarios and fragility modelling were conducted with the system dynamics modelling methodology in the Ventity simulation environment. The designed model has elements of discrete event simulations, system dynamics, and agent-based modelling. Importantly, real-world data for the period of five years (from the year 2016 to 2020...

Hence, digital transformation becomes a pillar of industrial policy, known in Europe as “Industry 4.0,” in China as “made in China 2025,” in Asia as “Smart Cities,” in Japan as “Society 5.0,” and in North America as “Industrial Internet.” These transformations will change the industrial landscape, toward Quality 4.0 and therefore, our lives. The presented research was conducted on quality management employees in Portugal and it aims to analyze if such employees have the perception of the impact of Industry 4.0 in the quality management profession and the required and needed skills. After analyzing the answered questionnaires, 90 results were considered valid. This is the sample of our study. Simultaneously, the goal of this research is also to review and analyze the main topics in progress related to quality management for the fourth industrial revolution and how quality emerges of th...

In such circumstances, it is necessary to impact these criteria in order to maximize this difference. The selling products’ price, in modern market conditions, is a category which may not be significantly affected. So organizations have one option, which is the production cost reduction. This is the motive for business organizations and the imperative of each organization. The key parameters that influence the costs of production and therefore influence the competitiveness of organizations are the parameters of production machines and processes used to create products. To define optimal parameter values for production machines and processes that will reduce production costs and increase competitiveness of production organizations, the authors have developed a new mathematical model. The model is based on appli...

On the way to achieving this goal, a very successful approach is the employment of quality improvement projects. This chapter proposes a model for evaluation of projects for business process quality improvement. The performances of the treated type of projects are analyzed in the scope of standard ISO 215000:2015 and the results of good practice. An arranged pair (relative importance, value) is associated to each performance. The relative importance of project performances is assessed on the basis of experts’ judgments from the manufacturing industry and they are introduced by linguistic expressions which are close to human thinking. The values of project performances are determined by measurement or they are based on assessment by a project management team. Modeling of linguistic expressions is performed by fuzzy sets theory. The relative importance of each pair of business processes and project performances is determined on the level of the treated specimen of enterprises. The total score of the project is determined by using fuzzy logic . The model for evaluation of projects for business process quality improvement is verified through a case study example.

The most important characteristics and benefits of distant learning are time and place independence with individual studying pace of learning educational materials. Very important aspect of education especially in engineering and science is practical laboratory work where students gain very important practical experience about real world systems, their behaviour, laboratory and measurement equipment that is necessary for complete education of the future engineer or scientist. While e-learning is very convenient for independent studying of theoretical materials in any educational area, there is a problem how to do the laboratory work at distance. Possible solutions are simulations of the laboratory conditions, and remote access to real laboratory equipment, not simulations. This paper deals with rem...

This part of energy recovering depends on many different factors related to the broad and local aspects of ELV recycling. The ELV recycling process is consuming energy from different energy sources (electrical, fossil), however, this consumption is lower in relation to energy consumption during the production of new vehicle parts from the very beginning. This article attempts to promote an integrated approach in the analysis of the problem of energy recovery through ELV recycling. Authors aim to analyze the ELV recycling process as an energy generator and to present possibilities for its energy recovery. The research analyses are based on the empirical investigation of ELV recycling in the Republic of Serbia, as a developing country, and on defined statistical model presenting the impact of ELV recycling on energy generation, spending, and conservation during one-year intervals...

Universities, as key provider of knowledge, and industry, as its largest consumer, are two pillows of this vision. Academic Institutions has a double role in provisioning of knowledge: "research" for creation of new knowledge and "education" as dissemination of current knowledge. In this investigation, a four-year cross-border collaboration is described, including strategy, mechanisms and tools adopted for supporting a wider cooperation between universities and industry. Background, challenges and concepts of long-term sustainability are also presented. Furthermore, a general overview of technical outcomes and advances, provided by a research and development joint action, thanks to this international cooperation, is illustrated. A deeper description regarding these technical investigations is proposed in the following articles o...
