Abstract: Based on the collaborative management theory of green supply chain, the aim of this paper is to establish the evaluation index system of coordination effect of steel enterprise green supply chain management from two aspects of economic performance and green performance. It selects Baosteel as the research object, evaluates the collaborative management of green supply chain by means of catastrophe progression method and coupling coordination degree model, and analyses the relevant data of enterprises from 2010 to 2019 Management level and the synergistic effect of green performance development.

Abstract: The transition of the most developed countries’ societies to a new phase based primarily on the creation, dissemination and use of knowledge, i.e. innovative development, has become a typical feature of modern economies. [..] Read more

Abstract: The article presents a statistical approach to the results of non-conformities of steel round bars over 12 months. Basic statistical measures, Pareto-Lorenz diagram, histograms, box plot, picture charts as well as correlation analysis were used to present the distribution of data regarding the number of non-conformities and dependencies in the analyzed data in a system according to the type of non-conformities found and in the time system - according to the examined months.

Abstract: Blast furnace process is the basic process of pig iron production. This kind of device has a very large volume, so every day it produces significant quantities of the products. [..] Read more

Abstract: The article presents the results of a study of project managers involved in improving teams at an international industrial enterprise. The enterprise mass produces and customises metal parts for the transportation industry. [..] Read more

Abstract: In the paper customer preferences regarding copper wires were determined, special attention to the technical characteristics of wires were focused, that would meet customer expectations. To build a quality house, information from direct production employees as well as technologists and constructors were used. [..] Read more

Abstract: The purpose of the conducted tests was to apply an integrally configured method of quality control of the condition of modified helicopter gearbox housing castings. The use of this innovative method (consisting of the following techniques: Pareto-Lorenz diagram, Ishikawa diagram and 5WHY method?). [..] Read more

Abstract: Jigless robot welding is one of the most demanding disciplines in the automation industry. Jigless processes offer significant benefits by reducing the cost of custom tooling and providing flexibility to process part variations with low batch sizes but make high demands on robotics and the know-how of suppliers and users. [..] Read more

Abstract: Electronic information transfer has existed for decades, and the many advantages of this type of communication are employed by large companies where quick, flawless and secure data transfer is essential. Many companies use advanced information systems internally, hence most of their documents are created in electronic format. [..] Read more

Abstract: Titanium, invariably for decades, is the most promising metallic material used in medicine (implantology). And its suitability is primarily determined by biotolerance, which depends on the preparation of the surface of the elements. [..] Read more

Abstract: One of the most commonly used methods of quality management in manufacturing and industrial enterprises is the Pareto-Lorenz analysis. This method is currently one of the most frequently used conventional tools for the improvement the product quality and processes. [..] Read more

Abstract: The aim of the study is to identify the causes of non-compliance of castings and ultimately, using quality management tools (5W2H I diagram Ishikawa), to reduce or eliminate the number of such non-compliance. The research was carried out using visual, luminescence and metallographic tests and the product was a diesel engine piston casting. [..] Read more

Abstract: The introduction of a high degree of automation, such as robotic manipulation in metallurgical processes is no longer a difficult discipline with limited use although these processes are characterized by a specific environment that sets high demands on automation. Forging is a manufacturing process involving the shaping of metal using localized compressive forces where robot manipulates step by step through the forging process until the finished workpiece is removed from a forging press.

Abstract: The investments affect the development of enterprises. In the perspective of Industry 4.0, if there were no impact of the COVID-19 pandemic on economies, enterprises would continue to realize strong investment strategies. [..] Read more

Abstract: The resilient supplier management is a crucial part of the resilient supply chain management. The topic becomes very urgent due to the increasing number of disruptions, which appears in today’s global and turbulent business environment. [..] Read more

Abstract: Due to the constant growth of the copper industry, the increase in production costs and complexity in the composition of the feed of the production processes that make up the industry, the analysis of alternatives that improve efficiency by studying the dynamics of the processes represents a significant cost reduction. Then, the generation of analytical models that represent the dynamic behaviour of production processes has the potential to contribute to generating a better understanding of the operating parameters that have a greater impact on the response (s), in addition to identifying operating restrictions and optimal levels of operation.

Abstract: The aim of the paper is to analyze and describe recent application of management tools in the enterprises worldwide including their utilization and trends in timeline compared to industrial companies in Olomouc region, Czech Republic. The main data source for presented paper is the research performed by Bain & Company, Inc. [..] Read more

Abstract: A possible alternative to the established press hardening steel 22MnB5 are hot formed martensitic chromium steels. Both strength and ductility of the martensitic chromium steels can reach very high values with appropriate heat treatments. [..] Read more

Abstract: Moroccan clay ghassoul (GHA) was used in preparation process of electrically conductive nanocomposite contained polypyrrole (PPy/GHA). Based on our previous studies on electrically conductive nanocomposites, the calcination may lead to formation of graphite and few-layer graphene. [..] Read more

Abstract: This review paper focuses on semiconductor quantum dots (QDs) embedded inside semiconductor heterostructures prepared by Metalorganic Vapor Phase Epitaxy (MOVPE) technology and based on our contribution in [1]. Semiconductor direct-bandgap materials have much higher energy conversion efficiency than the light emission from atoms/molecules in a glass matrix or from most other light sources, but they have a broad band or multimode light emission spectra.
