Abstract: The paper deals with problems of modelling technological processes in cases when the available data sample is of small size and contains outliers. The essence of the method used in the paper lies in robust quantitative characteristics. [..] Read more

Abstract: The paper presents the identification and analysis of the most important conditions for logistics in the selected company, particularly, taking into account the field of procurement, production and storage, distribution and sales, transport and costs. The empirical studies covered one of the Silesian metallurgical companies. [..] Read more

Abstract: Stable process can be called a process in which variability is the result of many accidental causes, resulting in minor changes, not a specified number of reasons, resulting in significant changes in the parameter values. In the article the map of process stability, which is a result of process stability (X axis) and product quality (Y axis), was used. [..] Read more

Abstract: The paper refers to a general idea of the multi-agent method for modeling the logistics system in the steel industry. The advantage of the use of the agent-based approach as decision making system in transport, is that the agent-based systems are efficient (asynchronous independent operation), reliable (failure of one agent does not cause failure of the entire system), flexible (can adapt the system to a larger size by adding new agents without impact on existing) and have an ability to respond to changes occurring in the environment.

Abstract: Research and Development is believed to be a major source of innovations, which are increasingly driving modern economic growth. Although we are convinced that investments in R&D and other innovation assets are desirable they are difficult to measure from business perspective. [..] Read more

Abstract: Production is concerned with short throughput times and high schedule reliability in order to on the one hand, fulfill customer demands and on the other hand, increase planning reliability. However, from the business perspective, it is preferred that the available production equipment is highly utilized and that there is the lowest possible WIP (Work in Process) level. [..] Read more

Abstract: Strong competition on the market has led to increased customer's requirements according to manufactured products. Customers expect unique products that meet their individual needs; low prices and a very good quality service. [..] Read more

Abstract: Nowadays one of the most important global issues in the heavy industry and specially in metallurgical sector is the allocation of carbon dioxide emission allowances. The equity in allocation of emission allowances is discussed offend with this problematic. [..] Read more

Abstract: The high cost of inputs and their continual change, efforts to retain core employees, unrealistic environmental standards, limits, taxes, levies and fees are increasing at the Czech metallurgical companies fixed costs and making them less competitive. This makes diagnosis costs in metallurgical companies, records any changes to the cost, consistently looks for the causes of changes including conservation point of view of an individual approach, even more important than before.

Abstract: A new original model of access to welded structures economic production; Design - Material - Technology - Quality model is here presented, explained and demonstrated on the practical case of GMAW (gas metal arc welding) fillet welding 4 mm steel sheets. Together 7 various methods of producing this type of joint were used. [..] Read more

Abstract: A new control method is proposed for controlling cooling temperature in steel plate production process. The proposed method is based on a locally weighted regression model, which is a type of Just-In-Time models. [..] Read more

Abstract: Polish metallurgical enterprises spend significantly less on R&D and innovation than their regional peers. The income and productivity growth in the last 20 years has been much faster than that of its neighbors. [..] Read more

Abstract: Optimal control systems is still relevant topic. In industries (especially in the range of metallurgy) that are primarily dependent on energy there are desirable either changes in technology and changes in existing technologies or changes of traditional materials for substituting ones or to explore possibilities for energy savings. [..] Read more

Abstract: The paper deals with the influence of important macroeconomic parameters on development of ironworks production prices. Macroeconomic factors and their effect on final prices (and pig nod foundry charge iron) are often undervalued next to closer surrounding forces inside industrial branch. [..] Read more

Abstract: Although profitability of reverse logistics can have its roots in rather diverse areas, most of them can be attached to how and how well reverse flows are managed. Specific character of reverse flows requires planning and innovative approach as well as some level of managers´ understanding and commitment, there are also several drivers for companies which make them to be involved in reverse logistics management. [..] Read more

Abstract: A steel industry was, like all other market sectors, struck by financial and economic crises whose impacts are noticeable even a couple years after, in 2015. In such an uncertain and unstable environment, it is severely crucial to achieve the maximum efficiency of business processes. [..] Read more

Abstract: Quality is one of the basic elements influencing the final shape of the chosen logistic strategy. Low level of quality is one of the most visible indicators of efficiency of supply chain. [..] Read more

Abstract: The influence of cerium addition on solidification structure of the low-carbon 42CrMo4 steel was investigated. Alloys were prepared by means of a centrifugal casting. [..] Read more

Abstract: Special designs of nozzles or tuyeres are used in high-temperature units treating metal scrap for blowing gaseous technological media into the melt below the bath level. The higher technology utilisation of media is achieved by the blowing of media into the melt below the bath level. [..] Read more

Abstract: Outdated machine for continuous casting of steel (CCM) has often fail to meet the requirements for production of the desired high quality carbon or stainless steel blank. Their control system acts as a so-called Black Box System, which provides operators the possibility of the system as needed to adjust and tune in order to achieve the required quality of steel produced.
