Abstract: The article discusses the CA systems use and the application of the modularity principles in the design new, or modernizing existing production systems. This paper describes the principle of modularity as a tool for streamlining design. Design of system with the help of computers and assisted by programs. These allow creating 3D model design before the actual implementation. It is also possible to compile a control circuit simulation and detect and eliminate deficiencies still in design stage. In paper conclusion is illustrated design, automation of existing painting line for the varnish handles. Described principles have been applied, as well as CA systems, CATIA and FluidSim.

Abstract: "If you don't innovate, you will not survive. This statement has been especially true over the last century. The most critical factor is the speed of implementation of the particular innovation. High demands on the quality of process control, more and more require the use of supporting tools that enable us to get complex and detailed analysis of the process. For this reason attention is being paid to computer-aided simulation tools. Use of computer-aided simulation is still not as widespread as might be expected nowadays. However, expanded use of this tool is only a matter of time. This statement is confirmed by experience from many innovation projects, where the application of such computer-aided simulation tools was not only advantageous, but even necessary. This article deals with the application of computer-aided simulation in the field of process innovation. The particular case study shows the benefits of computer-aided simulation and the necessity of the connection and integration with the traditional methods (descriptive or analytical). It describes concisely the innovation process for an example of a JIT assembly (Just in Time). The traditional methods (ABC analysis and analysis of the activities that do not add value - Non Business Value) only partially solved the task of the project. To complete it and find the right solution, it was necessary to use dynamic analysis using computer-aided simulation. In conclusion, further opportunities to use computer-aided simulation in this field are being outlined.

Abstract: The main focus when improving business processes is on the analysis of material flow. Thorough analysis of the information flow and associated information systems is still undervalued. Working with inaccurate and/or obsolete data leads to incorrect outputs that negatively affect the entire control process. Analysis of the state of material has to go hand in hand with the information analysis. A mini audit of the information flow and information system can be carried out, which follows the classic principles of VSM (Value stream mapping), in order to make an initial analysis of the information flow and information system. Information about the current state of the process together with a measure how well it is represented by the model in the information system can be obtained thanks to this mini-audit. This article focuses on this mini-audit and briefly describes the auditing process. The details of how to create VSM maps is discussed with the main focus on an information flow where the key elements are the inputs and the outputs of the job orders for planning and production management. Attention is also focused on the form of delays in discrete-event recording in the production process which appear in the information system.

Abstract: Application of agent based approaches is frequent in systems with artificial intelligence. This method has been used in simulations as well, however application in this field is rather novel. The paper surveys formation possibilities of agent based structures in the simulation of an example material flow systems. Further, considerations are also presented, how these models can be made adaptive, which makes them capable of continuously modify their features to the modeled physical system. Finally a framework for a proposed modeling problem is introduced.

Abstract: Machining of different materials brings increasing of productivity, economical effectivity and quality of work piece. Constant development of Robotics and information systems brings new views of using robots in a process of production. Instead of using robots for a purpose of manipulation with work pieces, it is possible to use a robot directly for machining. Robotics machining technology has its advantage in application, which represents an adequate alternative in machining of metals on tradition of machine systems. The aim of the suggested plan of the experiment is to identify the optimal approach and combinations of each parameter during milling.

Abstract: Design solution of material flows planning in manufacturing systems belongs to key aspects that the project engineers must resolute. The conception and technical material flow realisation considerable define the dependability, promptness, consistence and next needed flows of work in the material flow. These necessary material flow functions influence the production quality, the amounts of production costs and the producer profitability. Follow up is starting to use the simulation methods at material flow designs and innovations. These methods are used in verification of new designs of material flows or in validation of just realised material flows. There is possibility of verification and validation usage by software Witness. Witness software simulation offers an optimal solution of problems by means. It enables to simulate working environment as well as material flows. The result is the higher efficiency of whole process and elimination of problems.

Abstract: The paper presents an analysis of the materials flow in the company on the example of the production process of the selected product. The analysis was carried out in three stages. This division has enabled to take into account many factors that have a significant impact on the internal transport during production. The first step in the analysis was to determine the current situation of the flow of materials. In the second stage, the obtained data were used to develop a detailed program of internal transport, associated with the production of the considered product, and the last stage of the analysis was to identify opportunities for rationalization actions. The rationalization concerned the machine tools spatial location, the choice of handling equipment and transport tasks.

Abstract: Production engineering is currently characterized with continuously changing and expanding, producers have to be flexible in this regard. It means that need to offer production possibilities, which can respond to the quick change. Engineering product development is focused on supporting CAD software; such systems are mainly used for product design. The integration of flexible manufacturing systems and subunits together with product design and of engineering is a possible solution for this issue. Product designers use different types of CAD systems that are incompatible with each other. To enter a new product, it is necessary to transform CAD data and re-enter into the production system used by the manufacturer. The solution is to generate NC data directly from a CAD model and transform the data uploading to control system of flexible manufacturing system. The integration of flexible manufacturing systems and subunits together with product design in CAD and of engineering is a possible solution for this issue. Integration is possible through the implementation of CIM systems. Such an explanation and finding a connection between CAD and production system ICIM 3000 from Festo Co. is engaged in the research project and this contribution.

Abstract: The purpose of this article is not only to get new knowledge but also shown on the automation and robotics at Slovak University of Technology - Department of production devices and systems in Trnava. The automation and robotics are oriented to different devices, but I will focus to intelligent assembly cell. In this contribution, the assembly workspace of this cell is solved. I will focus to hardware equipment such are sensory devices and their allocation in this assembly workspace.

Abstract: The goal of this work was to use the process of knowledge discovery in planning and control of production processes. This work is focused on the prediction of the system behavior from the data of production process. The classification was used as a task of data mining. Some predictive models were created and the predictions of the production process behavior were realized by varying the input parameters using selected methods and techniques of data mining. It can be confirmed that the selected input parameters will lead to the fulfillment of the declared objectives of the process. The process of knowledge discovery has been implemented in the program STATISTICA Data Miner.
