  • Dynamic Simulation for Optimisation Solution of Manufacturing Processes
    MATEC Web of Conferences 244, 01010 (2018) https://doi.org/10.1051/matecconf/201824401010 ITEP’18 Dynamic simulation for optimisation solution of manufacturing processes Vladimíra Schindlerová1,*, Ivana Šajdlerová1, Dominika Lehocká2 1VŠB - Technical University of Ostrava, Faculty of Mechanical Engineering, 17. listopadu 2172/15, 708 33, Ostrava - Poruba, Czech Republic 2Technical University of Kosice, Faculty of Manufacturing Technologies with a seat in Presov, Bayerova 1, 080 01 Presov, Slovak Republic Abstract. One way how to study the real behaviour of industrial processes or systems in practice is to use computer simulations. We can simulate different conditions and find optimal parameters without increased risk. The right application of these parameters in practice can produce the desired results. The advantage is not only the safe verification of various variants of the simulated parameters, but also the possibility of their use in different areas of industrial practice. This article deals with an example of the use of simulation in the production of the selected automobile cooling system component. The simulation model was created to design the correct number of Kanban circuits to shorten production lead time and to reduce inter-operational supplies. The suitability of using computer simulations to optimize the production processes and systems in practice can be confirmed based on comparison of the results from the computer simulation with results achieved in practice. Keywords: Dynamic Simulation, Optimisation, Manufacturing Processes, Kanban 1 Introduction Evaluating the quality of delivered products or provided services by customers depends on the degree of fulfilment of the expected requirements whether it is the ability to deliver products or services corresponding to the customers´ ideas as for the appearance and design, correct amount, agreed delivery times or required quality at reasonable prices.

  • Modeling Data Heritage with Sybase Powerdesigner®
    MODELING DATA HERITAGE WITH SYBASE POWERDESIGNER® THE ENTERPRISE. UNWIRED. WHITE PAPER Knowing where our data came from and where it is going is one of the most challenging aspects of managing today’s data center. As our systems become more integrated and interdependent, through replication, ware- housing and system integration efforts, the impact of a change on any data element can be huge. Having the ability to document, and then report on, data heritage, allows users to more effectively and efficiently predict the impact of a change, as well as streamline its implementation. Managing Data Heritage, the sources and targets of data, require a 21st century modeling tool like Sybase PowerDesigner. REQUIREMENTS FOR MANAGING DATA HERITAGE When managing data heritage, it is important to be able to clearly document the data elements (aliases, format, statistics and other quality indicators), document the sourcing information and target data systems information (including transformation rules), and stewardship information (who created and modified the data elements, security and access rights and history). Starting with the processes, users need to be able to trace to all data elements (and any interim elements) to all final implementation points. To achieve this, users need to document: ■ All data processes with business definitions and requirements ■ All data items at a conceptual level with business definitions and stewardship details ■ All physical data (Tables/Columns) with version history ■ All dependencies between source and target tables and columns A TOOLSET AND A SOLUTION: BUILDING BLOCKS FOR DATA HERITAGE To address these needs, PowerDesigner offers rich process modeling, data analysis and design techniques that capture and manage the dependency metadata needed to document data heritage.
