Currently, the manufacturing management board applies technologies in line with the concept of Industry 4.0. Cyber-physical production systems (CPSs) mean integrating computational processes with the corresponding physical ones, i.e., allowing work at the operational level and at the strategic level to run side by side. This paper proposes a framework to collect data and information from a production process, namely, the burnishing one, in order to monitor real-time deviations from the correct course of the process and thus reduce the number of defective products within the manufacturing process. The proposed new solutions consist of (i) the data and information of the production process, acquired from sensors, (ii) a predictive model, based on the Hellwig method for errors in the production process, relying on indications of a machine status, and (iii) an information layer system, integrating the process data acquired in real time with the model for predicting errors within the production process in an enterprise resource planning (ERP) system, that is, the business intelligence module. The possibilities of using the results of research in managerial practice are demonstrated through the application of an actual burnishing process. This new framework can be treated as a solution which will help managers to monitor the production flow and respond, in real time, to interruptions.

In the era of smart manufacturing and Industry 4.0, the rapid development of modelling in production processes results in the implementation of new techniques, such as additive manufacturing (AM) technologies. However, large investments in the devices in the field of AM technologies require prior analysis to identify the possibilities of improving the production process flow. This paper proposes a new approach to determine and optimize the production process flow with improvements made by the AM technologies through the application of the Petri net theory. The existing production process is specified by a Petri net model and optimized by AM technology. The modified version of the system is verified and validated by the set of analytic methods safeguarding against the formal errors, deadlocks, or unreachable states. The proposed idea is illustrated by an example of a real-life production process.

Risk analysis is a tool supporting and allowing to determine the level of risk and the effects that may cause potential threats. Based on the results obtained, during the analysis of hazards in the chocolate production process, it was possible to assess the existing hazards and assign them a specific weight, which translates into risk levels that have a potential impact on the health safety of dark chocolates. Dark chocolate has been shown to be a relatively safe product. Many stages in the technological cycle allow for the elimination of hazards from raw materials and earlier processing stages, which is supported by properly designed quality systems.

Purpose: Critical defects are of great significance when evaluating the production process effectiveness, especially in the automotive branch. It is important to analyse these defects and distinguish the crucial ones. In this article, the authors have identified critical defects in the process of brake master cylinders production using quality management tools, and proposed improvement actions. Design/methodology/approach: The aim of the article was to analyse defects and the reasons for their occurrence, and improve the production process of master cylinder with special attention to critical defects. In order to improve this process, critical flaws had to be identified and eliminated from the entire set, which was the engineering problem to be solved. Then the causes of their occurrence as well as the factors causing process disturbances affecting the final occurrence of the defect were identified, and actions eliminating or limiting their occurrence were proposed. In the project, they were used to analyse the tools and principles, i.e. process diagram, Pareto-Lorenz diagram, cause-effect diagram, and to improve the Poka-Yoke process. Findings: Based on the examined causes of defects, improvements were proposed, i.e. guides for applying the body, a program stopping the piston assembly station to control the oil level, purchase of caps from sealed material and the need to work in long-sleeved work clothing, moving the body type verification camera from the final to first station, pallet spacers to protect against piston damage, change of supplier, especially of body castings. Research limitations/implications: The major limitation of the paper is that it is based on one case of an organization. In the future, it will be necessary to conduct studies in more organizations so as to find out if the same result can be achieved. Originality/value: Until now, no quality management tools have been used to analyse and organize the formation of defects in production processes.

The aim of the study is to use the 8D methodology to solve the production problem, which was the incorrect installation of the rings in the piston designed for excavators. The idea of the method used is to correctly identify the causes of the problem and implement corrective actions to prevent recurrence of the problem. In order to detect as many potential causes of non-compliance as possible, the working team conducted brainstorming sessions and then developed the Ishikawa diagram. Team members found that the most common source of the problem was human error. In order to eliminate it, it was decided to carry out a series of training courses and to additionally equip assembly stations. The presented methodology of solving quality problems can be implied in every production company.

The article presents the analysis of the implementation of selected elements of car transport in the aspect of ecology. The basic issue that affects the protection of the environment (ecology) is the value of energy intensity in the manufacture of products. The elements made in the production process of plastic mouldings were compared. The amount of energy in kJ needed to produce 1 kg of a given product was estimated. Next, the dependencies between the value of computational energy intensity and the emission of gases affecting the environment of CO2, SO2, NOx were presented. As a conversion factor according to GUS data, it was assumed that 1kWh production in Poland causes emission of 800 g CO2, 7 g SO2 and 3 g NOx.
