Recently, governments used this approach to determine the evolution of the COVID-19 pandemic. In this context, M&S tools that consider geographical information can improve the quality of the simulations. This research presents a methodology that allows modelers to prototype disease spread models that include geographical information. The model can be easily parameterized for other geographical regions and diseases.

This paper presents a systematic way of modeling and simulating prescribed fire ignition techniques. An ignition plan specification is developed to formally specify the ignition activities and schedules of prescribed burning events. The ignition plan specification is used by ignition agents, which transform an ignition plan into detailed tasks and carry out the ignition tasks while coupling with a fire spread simulation model. Simulation results of six ignition scenarios corresponding to six basic ignition techniques are provided. The simulation results demonstrate the effectiveness of the developed modeling approach and show that different ignition techniques can result in different fire growth patterns for prescribed fires.","PeriodicalId":6782,"journal":{"name":"2021 Annual Modeling and Simulation Conference (ANNSIM)","volume":"287 1","pages":"1-12"},"PeriodicalIF":0.0,"publicationDate":"2021-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75335042","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Providing accurate Channel State Information (CSI) is vital for optimizing m-MIMO communication systems. The complexity of channel reconstruction grows exponentially with the number of antennas, causing traditional methods to become increasingly complicated. Machine-learning techniques can be a useful alternative for channel reconstruction using partial CSI feedback. This paper presents the results of a simulation study built using the MATLAB 5G Toolbox and a neural network trained using the simulated data. The simulator emulates a 5G channel to generate its path delays and gains, and the realistic CSI feedback. This data was used to train and test a neural network to estimate the dominant path gains and delays. The models showed promising results while operating on limited CSI data.","PeriodicalId":6782,"journal":{"name":"2021 Annual Modeling and Simulation Conference (ANNSIM)","volume":"8 1","pages":"1-11"},"PeriodicalIF":0.0,"publicationDate":"2021-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75588848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To fill the gap, this research analyzes landscape change by considering the tele-coupling effects at the local scale between Owyhee county and Treasure Valley in Idaho, United States. The spatial distribution of recreational activities in Owyhee county are modeled by Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST). Land use and cover change (LUCC) are simulated using Multi-Layer Perceptron Neural Network (MLPNN). Results show that the tele-coupling effects have significant impacts on the nature-based recreation in Owyhee county. With the tele-coupling effects, MLPNN has achieved a high overall accuracy and kappa coefficient in LUCC. The findings suggest that the tele-coupling effects should be incorporated into the modeling of landscape change and SES. This study also provides policy implications for land management and stakeholder involvement in accommodating landscape change.","PeriodicalId":6782,"journal":{"name":"2021 Annual Modeling and Simulation Conference (ANNSIM)","volume":"10 1","pages":"1-12"},"PeriodicalIF":0.0,"publicationDate":"2021-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80277048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accurate forecasts of baseline loads are essential for DR programs. In the era of big data, machine learning-based approaches present a unique opportunity for baseline load forecasting. Thus, this paper presents a machine learning-based approach using a relatively less explored algorithm, Gaussian process regression (GPR), to forecast aggregate baseline loads. As such, a dataset was generated using a set of EnergyPlus simulations. Using the generated dataset, a GPR-based forecasting model was developed. In addition, support vector regression (SVR)-, artificial neural network (ANN)-, and averaging-based models were developed as baseline models for comparison. These models were compared in terms of accuracy, simplicity, and integrity. The prediction performance of the models showed that the GPR-based model is more accurate and reliable than the others. Such high performance shows the potential of the GPR in baseline load forecasting. GPR, therefore, can be used for DR applications.","PeriodicalId":6782,"journal":{"name":"2021 Annual Modeling and Simulation Conference (ANNSIM)","volume":"1 1","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2021-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82870455","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the development of artificial intelligence, Multi-Agent Reinforcement Learning (MARL) has shown positive potential in robot control, autonomous driving, and human-machine battles as its powerful learning capability for making intelligent decisions. There are many challenges in applying MARL directly to ABS, and there is no unified framework that integrates them. The paper proposed the Multi-Agent Discrete Event Simulation (MADES) framework based on several DEVS atomic models to construct the multi-agent system, which has advantages for representing various MARL architectures. A predator-prey system simulation with a mainstream MARL algorithm is built under our framework, the training curves and event transition time figure have verified the learning and the simulation performance of the framework.","PeriodicalId":6782,"journal":{"name":"2021 Annual Modeling and Simulation Conference (ANNSIM)","volume":"13 1","pages":"1-12"},"PeriodicalIF":0.0,"publicationDate":"2021-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79556694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the operational semantics of DEVS models is well defined, and it exists some attempt to characterize their behavior using temporal logics, there is no attempt to define their denotational semantics. The meaning of a DEVS model is the set of possible coupled input, output and state trajectories. Therefore, denotational semantics is a mapping from DEVS models onto an algebra of trajectories. In this paper, we use category theory to define this algebra. This algebra, called Dyn, is made of trajectories as objects, and the DEVS behavior and structure specifications are mapped onto morphisms between trajectories, exhibiting their coupling. This result opens the way to algebraic manipulations of DEVS models, as well as the access to the results and proof mechanisms available in category theory.","PeriodicalId":6782,"journal":{"name":"2021 Annual Modeling and Simulation Conference (ANNSIM)","volume":"32 1","pages":"1-12"},"PeriodicalIF":0.0,"publicationDate":"2021-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83540331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The tool automates the simulation of Cellular Discrete Event Simulation models of Carbon Dioxide dispersion indoors.
