Current information technologies and their subsequent applications in the industry enable a new view on already well-known processes, actions, phenomena and approaches, the realizations of which were very hard or not possible to accomplish nearly a decade ago due to difficult technical and economic conditions. This applies particularly to those areas of the processes industry, which are characterized...
This article deals with the creation of dynamic models in the form of transient characteristics obtained from the monitoring system boring machine-rock used in tunneling Branisko using the tunnel boring method (TBM). The rating system is the creation of statistical models and their approximation of the measured, respectively, monitored values. As a starting point a statistical model was used that...
KPIs (Key Performance Indicators-KPIs) are quantifiable values that reflect the critical success factors of operation, enterprise companies. Choice of these parameters depends on the type of system being examined. As an example of the technological process in finding the optimal mode, KPI respectively, is a process of rock disintegration. The theoretical basis is the energy of disintegration theory,...
Within technological processes of metallurgical and engineering production plants, the metal heating procedure is one of the most important operations having major impact on the production in terms of performance, quality and costs. By selecting a suitable annealing process control of steel coils we improve the quality of annealed batch and economic efficiency of furnace operation. When selecting...
Control of a system object or process requires knowledge on properties of the controlled technologies/objects, as well as knowledge of the control patterns, which means detailed knowledge of the impacts caused by the controlling intervention made in the process. It is obvious that precise and complete control has to follow the precise and complete information on the object's condition, mainly the...
The process of the disintegration of rocks, the mechanisms of mechanical disintegration and disconnecting tool wear has been studied for more than thirty years due to significant changes in the field of science and technology which cannot now remain without response. There were especially computers, sensors, monitoring and data archiving technologies, which have brought into this area of research...
Excavation of various underground structures, such as tunnels, caverns and linear mining structures using the tunnel boring machines (TBMs) has become an ultimate technology in underground construction in recent decades. Construction of TBMs has been improved over the years and still is being refined by introducing novel progressive materials. Technological processes of excavation have passed through...
Process optimization represents a search for the best solution at given limitations using a proper optimization method. An area for optimization is open only in case of having a chance for selection from several variants, while the individual variants are not equivalent usually. If the process cannot be optimized during the real-time operation or at experimental device, due to technological conditions...
