Background and Purpose: Business process simulation (BPS) model is based on real-life data form sources like databases, observations and interviews. It acts as “as-is” business scenario can used for reengineering. The main challenge is to gather relevant data and to develop simulation model. Research aims to elaborate BPS model and to systematically assess how close to reality it is. Design/Methodology/Approach: The research has been performed in Polish telecommunications company. Authors investigate technical process of expanding cellular network. After elaborating “as-is” model, authors use ADONIS simulation tool to run a series simulations and confront simulation results with actual historical events. After this, assessment whether computer simulation model can precisely map real-life business process - and consequently act as credible basis for process improvement - is made. Results: The simulation model has been constructed with data from the WfMS database, observations, staff knowledge and their experience. Fully equipped simulation model is found to allow reconstructing the historical execution of business activity with low margin for error. Some limitation were identified and discussed. Conclusion: BPS is not a popular approach for process reengineering and improvement yet. Data collection issues for BPS that require adopting process mining techniques and additional information sources are among the reasons for that. In our study, computer simulation outputs are compatible with historical events. Hence the model reflects the business reality and can be taken as a reference model while redesigning the process.

APEX (Airborne Prism EXperiment) is a high spectral and spatial resolution hyperspectral sensor developed by a Swiss-Belgian consortium on behalf of the European Space Agency. Since the acceptance of the instrument in 2010, it has been operated jointly by the Flemish Institute for Technological Research (VITO, Mol, Belgium) and the Remote Sensing Laboratories (RSL, Zurich, Switzerland). During this period, several flight campaigns have been performed across Europe, gathering over 4 Terabytes of raw data. Following radiometric, geometric and atmospheric processing, this data has been provided to a multitude of Belgian and European researchers, institutes and agencies, including the European Space Agency (ESA), the European Facility for Airborne Research (EUFAR) and the Belgian Science Policy Office (BelSPO). The applications of APEX data span a wide range of research topics, e.g. landcover mapping (mountainous, coastal, countryside and urban regions), the assessment of important structural and (bio)physical characteristics of vegetative and non-vegetative species, the tracing of atmospheric gases, and water content analysis (chlorophyll, suspended matter). Recurrent instrument calibration, accurate flight planning and preparation, and experienced pilots and instrument operators are crucial to successful data acquisition campaigns. In this paper, we highlight in detail these practical aspects of a typical APEX data acquisition campaign.

This paper examines various components of Syriusz – the computer system used by public employment services in Poland – in terms of the possibility of using it for the evaluation of gross and net active labour market programmes efficiency. The construction of the system has been described, its analytical limitations have been indicated, and recommendations on the required modifications formulated. Additionally, tools and methodology of supplementing the information with survey data have been presented.

The implementation of the HMI (Human-Machine Interface) operator panel on the production line is a new stage of the digital transformation of a paints and varnishes manufacturer in the SMEs sector. As part of an innovation plan, the process of production data acquisition was restructured, by means of IT (Information Technology), into an ERP (Enterprise Resource Planning) system. The introduction of an HMI panel made it possible to digitalize data acquisition and operation reporting to the ERP system. The digital transformation of the SME 4.0 company was modelled on the Industry 4.0 trend solutions. The specialized model, developed according to RAMI 4.0 (Reference Architecture Model Industry 4.0), effected change of a partial and local nature in the enterprise. The data is now entered directly into the production area by the employees on the technological line, once they have logged in to the ERP system. Access to digital production data obtained from a SSOT (single source of truth) benefited all those who used the ERP system. A postimplementation analysis of a two-year application of the restructured data acquisition process indicates the business areas which profit from digital operational data acquisition and higher quality production reporting.

Celem artykułu jest ukazanie transformacji cyfrowej przedsiębiorstwa produkcyjnego, prowadzonej według modelu referencyjnego architektury przemysłu czwartej generacji RAMI 4.0, w zakresie akwizycji danych produkcyjnych, z zastosowaniem panelu operatorskiego HMI. Zagadnienia te zostaną omówione na przykładzie przedsiębiorstwa produkcji farb i lakierów sektora MŚP, w którym autor artykułu podczas stażu wdrożył rozwiązanie akwizycji danych produkcyjnych, dotychczas dostarczanych w technologii papierowej. Cyfrowa transformacja danych w przedsiębiorstwie MŚP 4.0 została zamodelowana według aktualnych trendów Przemysłu 4.0. Model wdrożeniowy opracowano według modelu referencyjnego RAMI 4.0. W artykule zostaną przedstawione inicjatywy i skutki transformacji cyfrowej według modelu referencyjnego RAMI 4.0. Akwizycję danych i raportowanie do systemu ERP bezpośrednio z linii produkcyjnej umożliwił panel operatorski HMI. Analiza powdrożeniowa z dwuletniej eksploatacji przebudowanych procesów akwizycji danych pozwoliła określić obszary biznesowe korzystające z niej i wyższej jakości raportowania produkcji. Wskazano efekty ożywienia rytmów funkcjonowania przedsiębiorstwa na skutek dostępu do danych produkcyjnych wszystkich podmiotów czerpiących z jednego źródła danych SSOT w ramach systemu ERP.
