Opis:
The aim of the article is to analyze the impact of effective time management on the performance of workstations in the context of the conflict between maximizing workstation utilization and minimizing the number of items waiting in the queue. The article utilized the FlexSim program to build a simulation model of the workstation and conducted optimization using the built-in optimizer. The research demonstrated that effective time management has a positive impact on workstation performance by reducing the number of items waiting in the queue, leading to increased throughput and reduced delays in production processes. An important aspect of the analysis was the application of a multi-criteria optimization approach, which allowed for achieving a balance between maximizing workstation utilization and minimizing the number of items waiting. Multi-criteria optimization considers diverse goals and decision criteria, leading to a more comprehensive approach to optimizing production processes. As a result, effective time management on workstations, based on analysis and multi-criteria optimization, can significantly improve the efficiency and performance of production processes. This analysis can be a valuable tool for organizations seeking to optimize their processes and achieve a competitive advantage in the market. The analysis conducted in the article confirms that effective time management has a beneficial impact on workstation performance. The use of a multi-criteria approach in optimization enables achieving a balance between various decision factors. The presented simulation model and research results can be useful for decision-makers in the manufacturing field who aim to make more informed decisions regarding planning and optimizing production processes to enhance efficiency, effectiveness, and customer satisfaction.

Opis:
The paper presents results of simulation conducted as afirst step of 4-stroke spark ignition experimental engine testing. The simulations were performed in a KIVA-3Vsoftware, which is intended to carry out a 3-D simulations of engine's processes. The source code of the software has been modified in order to apply it for gas injection. Original version of the software has been designedto simulate liquid fuel injection only. The simulation of direct CNG injection and combustion has been done for stratified and homogenous modes in order to check the assumed injection, ignition and charging parameters. Important assumption is that the injector had only one nozzle with flow area equal to 2 mm2. Two different cases of fuel direct injection for stratified charge have been analysed. In the first case fuel jet was almost vertical. In the other one fuel jet was nearly horizontal. Further testing has been performed using one-cylinder motorcycle 4-stroke SUZUKI DR-Z400S engine adapted to CNG fuelling. Such an engine has a suitable high compression ratio for CNG fuelling. The simulation has confirmed assumed parameters and has shown that one nozzle injector doesn't provide required fuel stream dissipation and piston crown modification is needed to direct fuel stream in spark plug area. However doing simulation requires some effort this example has shown than this is very important step before conducting experimental tests which provides crucial information and helps to avoid expensive mistakes which can be made during experimental engine preparation.

Opis:
The paper considers the problem of the influence of constitutive model parameters on the results of FEM-based simulation of the orthogonal cutting process using C45 (AISI 1045) carbon steel and multilayer-coated carbide tool. The simulations were based on the power constitutive law (PL) with a special consideration of the temperature-related thermal influences. The sensitivity analysis performed concerns the models proposed by Özel and Kalhori and own data in the form of multi-regressive equations for the substrate and coating components that were applied. In particular, the values of n exponent were varied in order to assess the simulation results. The FEM simulations include the average interface temperature, the distribution of temperature on the rake face and within the wedge body, as well as cutting forces. By modifying the PL parameters, the prediction errors lower than 15% were obtained.

Opis:
The article deals with the modelling of the technological process at a quarry. The process modelling was carried out applying the simulation. The analysis of the operations performed within the technological process was used as the basis for the creation of the simulation model in the ExtendSim simulation software. The model simulation consisted of two parts. The first part represented the work cycle of a lorry – loading the lorry, a journey with the loaded material, emptying the load and a journey back to the loading station. The second part represented the work cycle of a loader that loads the material onto the lorry. The designed model was used to carry out several experiments. The article presents the results of two experiments. The simulation experiments were carried out for two different simulated times; the simulated time of 1 hour and the simulated time of 7.5 hours, representing 1 work shift. The results of the simulation comprised several parameters of time- and operation-related indicators. The presented simulation model is an appropriate accessory tool for the decision-making process when designing new systems or assessing the existing ones.

Opis:
Artykuł przedstawia wyznaczanie i modelowanie składowych sił szlifowania i na ich podstawie analizę zjawisk energetycznych towarzyszących szlifowaniu. Obecnie wiele mówi się o globalnej oszczędności energii. Ograniczenie wydatkowania energii w trakcie procesu szlifowania nawet w niewielkim procencie, w skali makro może przynieść bardzo wysokie korzyści. Z obszernej literatury dotyczącej tematu artykułu przeanalizowano publikacje znaczące dla rozwoju technologii obróbki ściernej, zwłaszcza dotyczące aspektów energetycznych tego procesu. Szczególny nacisk położono w artykule na procedury wyznaczania kontaktów ziaren podczas szlifowania, wynikiem czego jest pomiar sił w warunkach laboratoryjnych. Autorzy artykułu przedstawiają modele wyznaczania sił składowych szlifowania pojedynczym ziarnem ściernym oraz przedstawiają, wyznaczone metodami symulacji komputerowej, najefektywniejsze rozwiązania obniżenia energii w procesie szlifowania, przy zachowaniu znormalizowanej jakości wyrobu końcowego.
The paper presents the method of modeling and determining the components of grinding forces based on the analysis of energetic phenomena accompanying grinding. The global energy-saving manufacturing is the most important problem to be solved nowadays. Limitation of energy consumption during grinding process, even in a small percentage, could be highly profitable in macro scale. From among the numerous publications dealing with the subject of the paper there were selected and analyzed those concerning the development of grinding technology, especially describing energetic aspects of the process. The paper focuses on the detailed procedure of determining grain contact with the material machined, the result of which is possibility of measuring the grinding forces in a laboratory. The procedure of determining a single grain contact profile is described. The paper presents a new concept of the analytical procedure for calculating the grain load in the grinding zone by taking into account the process of ploughing and side pile-up formation on the lengthwise of the cut. The authors also took into consideration random character of the grain contact by introducing empirical coefficients defining the probability of chip formation. There are presented the models of calculating the single grain cutting force components and the most efficient solutions, determined from computer simulations, for reducing the energy consumption during grinding when keeping the final quality of the workpiece surface.

Opis:
The world around us is a very complex and multi-parametric system, like the weather, traffic, operation of machines, production processes, service processes, etc. Understanding of the characteristics, operation and behaviour of these systems and processes is not easy due to their complexity. The design of optimal production and service procedures is an essential task for planners. The target is the increasing of the efficiency of the production and service and analysis of the effect of parameter changing. There are lot of tools and sophisticated methods for design, analysis and improvement of logistical processes. The most often used analysis tool is the simulation in the production processes. Our aim in this article is to show that the simulation can be used efficiently in case of analysis of service processes, not only in case of production processes. The simulation is available for bottleneck analysis of service activities not only for production processes. In this study the simulation of a service process was realized by the AnyLogic software. The relevance of the simulation technique for analysis of complex service processes is proved by a case study of a service and maintenance activity of a multinational shopping centre.

Opis:
The simulation and modelling paradigms have significantly shifted in recent years under the influence of the Industry 4.0 concept. There is a requirement for a much higher level of detail and a lower level of abstraction within the simulation of a modelled system that continuously develops. Consequently, higher demands are placed on the construction of automated process models. Such a possibility is provided by automated process discovery techniques. Thus, the paper aims to investigate the performance of automated process discovery techniques within the controlled environment. The presented paper aims to benchmark the automated discovery techniques regarding realistic simulation models within the controlled environment and, more specifically, the logistics process of a manufacturing company. The study is based on a hybrid simulation of logistics in a manufacturing company that implemented the AnyLogic framework. The hybrid simulation is modelled using the BPMN notation using BIMP, the business process modelling software, to acquire data in the form of event logs. Next, five chosen automated process discovery techniques are applied to the event logs, and the results are evaluated. Based on the evaluation of benchmark results received using the chosen discovery algorithms, it is evident that the discovery algorithms have a better overall performance using more extensive event logs both in terms of fitness and precision. Nevertheless, the discovery techniques perform better in the case of smaller data sets, with less complex process models. Typically, automated discovery techniques have to address scalability issues due to the high amount of data present in the logs. However, as demonstrated, the process discovery techniques can also encounter issues of opposite nature. While discovery techniques typically have to address scalability issues due to large datasets, in the case of companies with long delivery cycles, long processing times and parallel production, which is common for the industrial sector, they have to address issues with incompleteness and lack of information in datasets. The management of business companies is becoming essential for companies to stay competitive through efficiency. The issues encountered within the simulation model will be amplified through both vertical and horizontal integration of the supply chain within the Industry 4.0. The impact of vertical integration in the BPMN model and the chosen case identifier is demonstrated. Without the assumption of smart manufacturing, it would be impossible to use a single case identifier throughout the entire simulation. The entire process would have to be divided into several subprocesses.

Opis:
The aim of this research is to improve a warehousing process. Its operations are characterized by deterministic and stochastic parameters. In such circumstances, the classical approaches based on deterministic methods leading to better performance of the process would not provide the expected results. Thus, the authors propose the methodology of process improvement. Introduction of a new technical equipment and reassignment of tasks to employees was proposed. The problem has been solved, providing significant improvement of the warehousing process. The proposed methodology of simulation-based process improvement has been proposed and verified. The process map created as the result of process analysis facilitates and accelerates the simulation model construction. The possibility to reflect random values brings the model closer to reality and increases the credibility of results.

Opis:
This paper adopts a probabilistic fuzzy analytic network process (PROFUZANP) approach in developing a sustainable manufacturing strategy. In this hybrid method, analytic network process handles the complexity of the problem structure under consideration, fuzzy set theory is used to describe vagueness in individual decision-making and probability theory is used to handle randomness in group decision-making. This holistic methodological approach addresses complexity and uncertainty both in individual and group decision-making which is useful in modeling group decisions such as developing a sustainable manufacturing strategy. In this work, an inclusive approach of integrating traditional manufacturing strategy concepts and sustainable manufacturing principles is proposed as a unifying decision model. The proposed decision structure adopts the hierarchical structure of manufacturing strategy and explores the presence of strategic responses and stakeholders’ interests as significant components of sustainability. Using PROFUZANP, the decision model identifies the content policies of sustainable manufacturing strategy. This content strategy is expected to address both competitiveness and sustainability of manufacturing firms. Results are reported in this paper along with insights and future work. The contribution of this work is the integration of manufacturing strategy and sustainability into a coherent decision framework that requires the use of PROFUZANP in dealing with complex and uncertain group decision-making problem.
