The article describes a workflow system implementation project in a production company. A modern enterprise must operate efficiently and effectively. Efficiency defines activities aimed at obtaining the best possible results with minimum investment. The introduction of a new solution in the area of document management allowed to increase efficiency by reducing the workload on creating documents. The concept of workflow was defined and the situation in the company was described. Based on the analyzes, a new solution in the area of document management was proposed by implementing the workflow system. Maps of new document management processes were developed. The effect of introducing the workflow system is primarily the automation of creating all types of documents and full control over the flow of documents.

Increasing the role of sustainable production benefits in transforming manufacturing towards the sustainable organisation. The proposed model integrates two dimensions, namely, the Sustainable Business Model (SBM) and the Enterprise Resource Planning (ERP) system, and defines it as the SBM-ERP. This paper focuses attention on determining SBM-ERP based on the literature research, Fuzzy Analytical Hierarchy Process (F-AHP) method and the results of the analysis on the experiences with the implementation of the ERP system in manufacturing. It was determined that the proprietary approach allows the company’s sustainable manufacturing activities to be organised and monitored, based on real-time data and information, as updated and included in the ERP system. We also emphasized the practicality of the proposed approach for managers of manufacturing companies with an implemented ERP system.

This paper attempts to conduct a comparative life cycle environmental analysis of alternative versions of a product that was manufactured with the use of additive technologies. The aim of the paper was to compare the environmental assessment of an additive-manufactured product using two approaches: a traditional one, based on the use of SimaPro software, and the authors’ own concept of a newly developed artificial intelligence (AI) based approach. The structure of the product was identical and the research experiments consisted in changing the materials used in additive manufacturing (from polylactic acid (PLA) to acrylonitrile butadiene styrene (ABS)). The effects of these changes on the environmental factors were observed and a direct comparison of the effects in the different factors was made. SimaPro software with implemented databases was used for the analysis. Missing information on the environmental impact of additive manufacturing of PLA and ABS parts was taken from the literature for the purpose of the study. The novelty of the work lies in the results of a developing concurrent approach based on AI. The results showed that the artificial intelligence approach can be an effective way to analyze life cycle assessment (LCA) even in such complex cases as a 3D printed medical exoskeleton. This approach, which is becoming increasingly useful as the complexity of manufactured products increases, will be developed in future studies.

The article presents contemporary challenges faced by tire manufacturers. General trends in the development of the tire industry are outlined. The negative impact of rubber waste on the environment was emphasized. The production process of radial tires used in passenger cars is presented. The basic constructions of tires and the components used for their production are discussed. The meaning and functions of the tire components are presented. The flow of the production process has been described, including all its stages. The possibilities of modern VMI MAXX tire assembling machines were commented, and the tire assembling process was characterized in detail. Methods of routine tire quality control used in mass production are discussed. The values describing the uniformity of tires were characterized. The division of tire defects used in the tire industry is presented. The tools and methods for detecting tire defects were characterized. Contemporary trends in the elimination of tire defects have been identified, especially emphasizing the potential of methods based on the use of artificial intelligence. It was noted that a solution to reduce the amount of tire waste due to exceeding the uniformity limits is needed. Authors noticed new opportunities thanks to the modern technologies used to register the tire assembling process.

Reviewing the current state of knowledge on sustainable production, this paper opens the Special Section entitled “Sustainability in production in the context of Industry 4.0”. The fourth industrial revolution (Industry 4.0), which embodies a vision for the future system of manufacturing (production), focuses on how to use contemporary methods (i.e. computerization, robotization, automation, new business models, etc.) to integrate all manufacturing industry systems to achieve sustainability. The idea was introduced in 2011 by the German government to promote automation in manufacturing. This paper shows the state of the art in the application of modern methods in sustainable manufacturing in the context of Industry 4.0. The authors review the past and current state of knowledge in this regard and describe the known limitations, directions for further research, and industrial applications of the most promising ideas and technologies.
