Systems engineering (SE) approach is undergo-ing constant change and is already being used in many companies as part of product development. This approach, which offers many advantages in collaboration, efficiency and product quality, as well as cost, can meet the challenges of Industry 4.0. Various tools are needed to implement SE. These include a PLM system for collaboration during development, as well as various simulation en-vironments that are brought together to form a co-simu-lation. One way to enable communication for this is to use the OPC UA communication standard. The application of the SE approach will be illustrated using two application examples, namely a holistic simulation of a production plant with energy management and a teaching course.","PeriodicalId":262785,"journal":{"name":"Simul.

Based on two application examples, i.e. a DC-actuator and a brake pedal system, the analysis of this article demonstrates, which synergies can be achieved by applying system simulation. The first example, focussing on the simulation of the temperature behaviour of a DC-actuator to identy critical operating conditions, reveals an effort reduction by a factor of 4 in comparison to measurements. The second example, a brake pedal system, shows an approach of contact modeling between rigid bodies in Modelica, in order to analyse the kinematic movement of the pedal and its force-path characteristics. In this case, the original effort of model creation has been reduced by a factor of 10 s. Beside the increase of efficiency, the respective de-sign concepts could be optimized concerning the friction and temperature behaviour according to the specifications.","PeriodicalId":262785,"journal":{"name":"Simul.

A new robust and efficient formulation for stream-dominated thermal fluid systems has been de-veloped and published as open-source library.

{"title":"Modeling the Spread of Tree Pests after Aerial Pest Control with the Means of a Geo-Information System","authors":"Colja Krugmann, Jochen Wittmann","doi":"10.11128/sne.31.sn.10586","DOIUrl":"https://doi.org/10.11128/sne.31.sn.10586","url":null,"abstract":". As part of a student project for the module Environmental and Geoinformation Systems, this article takes up the discussion about aerial pest control in forests. A model based solely on publicly available data is created to identify the area in which the aerial application of insecticides is permitted. It further estimates the renewed spread of forest pests after the control measure using a simple dynamic model. The back-ground of this model is the fact that the insecticide is applied in compliance with protective zones around populated areas, as well as surface waters and forest edges. In those untreated areas of the forest, the pests survive and will spread anew. Assuming a certain duration for the propagation cycle of the pests as well as an average radius, the dynamic spread of the pest population over several propagation cycles can be simulated and displayed using simple onboard methods of a geoinformation system. The difficulty in determining these zones is the fact that the geodata of German forests is frequently intersected by small roads that are irrelevant to the aerial application of the insecticide. As a feasibility study, this paper proves that such a model can provide useful information. For the case of an actual aerial application of an insecticide, it provides a list of essential parameters for a practically oriented simulation.","PeriodicalId":262785,"journal":{"name":"Simul.

In the coming years, electromobility will be confronted with increasing demands regarding the reliability of electrical machines. In this paper a modeling methodology is presented, which allows to estimate the reliability and lifetime of the insulation system of electrical machines. Different statistical and physical modeling methods are presented, which are transformed for the later multiple regression. The methodology of Design of Experiments (DoE) is used to describe the insulation system. Since the effort for the experimental design of the DoE varies strongly with the number of effects to be investigated and the statistical accuracy, different experimental designs are presented, which can be considered for different numbers of factors. Depending on the research question, a suitable experimental design can be selected. For the calculation of the lifetime, Miner’s rule is used in addition to the multiple regression, so that the percentage lifetime consumption due to a load spectrum can also be calculated.","PeriodicalId":262785,"journal":{"name":"Simul.

Today’s operation of agricultural machines is still characterised by the use of fossil fuels. In the future, all-electric agricultural machines can be used, whose energy requirements must be covered by local renewable energies or the power grid. The occurrence of limit value violations in the power grid can slow down and hinder this change in agricultural operations. For this reason, this paper describes the modelling and simulation of all-electric agricultural machines, renewable energy systems and rural power grids and the evaluation of suitable energy supply strategies for the machines and needed in-vestments in the power grid.","PeriodicalId":262785,"journal":{"name":"Simul.

However, simulation in our area usually takes some time even if a preexisting model just needs to be parameterized; there is still the run time, which will usually take at least a few minutes if not hours. In our current case, a planner wanted to know for a given product mix situation and for an equipment group with specific characteristics how much he can utilize the equipment without violating flow factor targets. A question, which arises several times during a typical workday as new or-ders are coming in and the situation on the shop floor is continuously changing. Since the user is usually asking the same question just with different parameters we are able to solve the waiting time problem while still giving good decision support. Instead of simulating every scenario at the time the user actually needs these answers, we use data farming to generate a large set of data points that are then used to train a neural network. This neural network then substitutes for the simulation and responds to the user immediately.","PeriodicalId":262785,"journal":{"name":"Simul.

The RPDEVS (“Revised PDEVS”) formalism has been introduced to allow for a simple description of Mealy-type components that behave consistently. This made it necessary to change the way the simulator han-dles event chains. Using a simple example model we show that the proposed algorithm has serious problems with the resulting sequence of concurrent events. Therefore we introduce NSA-DEVS, a variant formalism that is inspired by ideas from non-standard analysis (NSA). It uses infinitesimal time delays to make a natural ordering of concurrent events easy, without the need to fix lots of additional parameters. As proof of concept we describe the example model in NSA-DEVS and implement it in a suitably twisted RPDEVS simulator.","PeriodicalId":262785,"journal":{"name":"Simul.
