Opis:
Many manufacturing systems must operate under resource constraints. Simulation can help to improve the operation of such manufacturing systems. This paper presents a practical approach how to conduct a simulation project. A Flexible Manufacturing System (FMS) was chosen for the simulation. The targets for FMS improvement were given. A set of measures was proposed to meet the given targets. Design of Experiments (DoE) was used to minimise the number of simulation experiments. There were simulated and evaluated various measures and control strategies and their influence on the FMS characteristics. Rough cost analysis of each simulated variant was done. Future research targets are presented.

W artykule omawia się pewien zakres pola prac badawczych o silnym powiązaniu z praktycznymi zadaniami planowania przestrzennego. Planowanie przestrzenne postrzega się tu jako znajdowanie możliwie najlepszych form struktury definiowanej jako rozmieszczenie elementów oraz organizację połączeń między nimi, na potrzeby systemu, jaki tworzy aktualny stan naszej cywilizacji. Prezentuje się tu pewien wachlarz podejść wypróbowanych w kilkudziesięcioletniej aktywności Katedry Planowania Przestrzennego na Politechnice Wrocławskiej, akcentując szczególnie ujęcia ilościowe i techniki modelowania symulacyjnego. Z jednej strony bierze się pod uwagę obecność spontanicznie działających wielkoskalowych mechanizmów dążących do swych stanów równowagi. Z drugiej strony stara się analizować proces dochodzenia do określonych decyzji podejmowanych przez użytkownika systemu cywilizacyjnego, kontrolując jego założenia i dezyderaty z punktu widzenia ich obiektywnego uzasadnienia i realnego prawdopodobieństwa ich urzeczywistnienia.
The paper discusses a certain section of the field of research with strong links to the practical tasks of spatial planning. Spatial planning is seen here as finding the best possible forms of structure, defined as the distribution of elements and organization of connections between them for a system that forms our current civilization. We present here a range of approaches proven in decades of activity of the Spatial Planning Department at the Wrocław University of Science and Technology emphasizing especially the quantitative techniques of simulation modelling. On the one hand, it takes into account the presence of spontaneous large-scale operating mechanisms striving for their equilibrium states. On the other hand, it seeks to analyze the process of inquiry into certain decisions taken by the user of the civilization system controlling its foundation and desiderata from their objective justification point of view and the real probability of their realization.

The paper presents the analysis results of the fan system using hardware/software multi-technology language VHDL-AMS (IEEE 1076.1) and System Vision design platform. The analysis was performed in the time domain for the selected sweep values of the component parameters. The sensitivity analysis was used to vary selected, user-specified percentage of rated values . The parameters were arranged according to the effect on the selected waveforms. The further analysis was performed using statistic method Monte Carlo (MC) and Worst Case (WCA). Results of simulation are presented and the advantage of MC simulation over sensitivity analysis was emphasized. Post processing measurement tools of MC results and calculator with the standard mathematical operators and advanced statistic functions were used to picture the system performance versus run number and to determine correlations between devices parameters and system performance. The obtained characteristics enable the designer to evaluate the reliability of the system when manufactured in the large scale and to state the worst case limits for the project.

Opis:
In a previous work [Pasini L and Sabatini S 2016 TASK Quart. 20 (1) 9], we described a technique that allows a specific system of urban traffic to be associated to a description file system, called Model.dat. This file contains a list of data objects that are defined in the library [Pasini L and Feliziani S 2013 TASK Quart. 17 (3) 155] and that form the architecture model of a vehicular traffic system. This model turns out to be a network of queuing systems. In this work, we illustrate how we adapted the old procedure to study a new urban traffic system. Moreover, through a new tracking procedure, we illustrate how we developed a graphic simulation able to reinterpret the data from the simulation of the queuing networks model, in order to make it easier to check the effectiveness of the simulator and to have a graphical way to analyze the data.

Opis:
Mathematical models of activated sludge process are well recognised and widely implemented by researchers since 1980's. There is also numerous software available for modelling and simulation of activated sludge plants, but practical application of those tools is rather limited. One of the main reasons for such a situation is a difficult process of model calibration the requires extended data sets collected at investigated plant. Those data are usually not included in a standard plant monitoring plan. In the paper the problem of model calibration with the data sets derived from standard monitoring plan is discussed with a special regard to simulation objectives and data availability. The research was conducted with operational data from Białystok Wastewater Treatment Plant. The model of the plant was based on Activated Sludge Model No.3 developed by IWA Task Group and implemented in ASIM simulator. Calibration and validation of the model gave promising results, but further applications should be carefully considered, mainly due to uncertainties underlying input data.

Opis:
Demographic research of the world population shows that societies are ageing. The ongoing changes in the population structure will require appropriate quantitative and qualitative adjustments in health services to meet the needs of society. Simulation methods turn out to be helpful in these kinds of analyses. In this paper, the authors present a case study on using discrete event simulation (DES) to support decision-making in the field of hospital bed management in the light of demographic changes. The case study was elaborated for one of the Polish district hospitals. A DES model was built to simulate admissions to two hospital wards: paediatric and geriatric. A series of experiments were carried out as based on real data extracted from the hospital database and forecasted demographic trends elaborated by the Central Statistical Office of Poland (CSO). The influence of demographic changes on hospital admissions in the chosen age-gender cohorts was explored, examining different variants of hospital bed availability. The results of the experiments show that demographic trends significantly influence healthcare admission and bed utilisation. The reduction in the number of admissions to the paediatric ward by about 6% results in a change in average bed utilisation from 57.90% to 54.06%. With about 12% more admissions to the geriatric ward, the change is from 68.88% to 75.59%.

Opis:
The business structure and process development in many modern companies is assisted by architectures, frameworks, and a new generation of computer systems with a broad representation of methods and tools of design and modelling, i.e. object-oriented, event-oriented, activity-oriented, process-oriented, agent-oriented, communication-oriented, behaviour-oriented, etc. are recommended. The aim of this paper is to compare micro- vs. macro scope modelling and to investigate the relevance of micro- and/or macro simulation in the context of business process management (BPM) modelling for organizational design/redesign. The BPM modelling features and some specific issues of simulation modelling are discussed. Combined with BPM modelling methodologies, these issues are used to drive a concept for development of an integrated methodology for BPM models’ building and simulation approach in organizational BPM design/redesign projects.

Opis:
The enhancement of surgical simulation tools is an important research study, to assist in the assessment and feedback of medical training practice. In this research, the Spring Tensor Model (STEM) has been used for laparoscopic end-effector navigation through obstacles and high-risk areas. The modelling of the surgical trainer as part of the laparoscopic simulator seeks to emulate the physical environment as a virtualized representation in the integrated infrastructure. Combining sensor network framework paradigms to a surgical knowledge-based construct demonstrates how STEM can enhance medical practice. The architectural hybridisation of the training framework has enabled the adaptation of STEM modelling techniques for a simulated laparoscopic training methodology. The primary benefit of the architecture is that this integration strategy has resulted in a seamless transition of the heuristic framework to be applied to surgical training.

Opis:
The dairy industry faces many challenges when compared to other sectors. On the supply side, due to the nature of the raw material, large inventories are not applied; during the manufacturing process, continuous production is highly sensitive to any sort of unplanned disruption; on the demand side, the market dictates the bulk powder commodity prices. In response to the growth in competition, dairy organizations’ strategy must incorporate technology into their daily processes in order to become more efficient, profitable and sustainable. To achieve desired levels of improvement, Modelling and Simulation (M&S) has been increasing in popularity in the decision-making process. Using a dairy company as a case study, this paper has highlighted the potential for M&S to be used as a powerful strategic tool for decision-making processes.

Opis:
The article presents a method for determining the content and temperature on the basis of spectra from remote measurements. The technique uses measurements of a high resolution radiation spectrum that allows the visibility of the individual rotational lines of gases such as CO₂, used here in the range of 2470-2495 cm¯¹. At the same time a new algorithm is applied of pre-processing the spectrum, involving the use of multiple ratios of intensity at several wavenumbers as input to an inverse model based on neural networks. Due to it, the dimensionality of the input can significantly be reduced. Additionally, the data interpreted do not have to be measured in units of spectral radiance. Thus only the calibration of the sensitivity of the spectrometer at various wavelengths is required. The neural models were constructed on the basis of data from the simulation. The proposed method works with a uniform layer of radiating gas for determining the temperature and CO₂ content. For a non-uniform layer it is possible to determine the line-of-sight temperature profile and average gas content. The method can be extended to different spectral ranges and to other gases present in substantial quantities in the exhaust gases of various processes.
