Abstract:
Abstract The simulation of electrical networks is very important before development and servicing of electrical networks and grids can occur. There are software that can simulate the behaviour of electrical grids under different operating conditions, but these simulation environments cannot be used in a single cloud-based project, because they are not GNU-licensed software products. In this paper, an integrated framework was proposed that models and simulates communication networks. The design and operation of the simulation environment are investigated and a model of electrical components is proposed. After simulation, the simulation results were compared to manual computed results.

Abstract:
Abstract This paper presents an integration mechanism for online communication between a discrete event simulation (DES) software and a system dynamics (SD) software. The integration between them allowed executing a hybrid and broader simulation, in which the complexity of the systems and their multi-faceted relationships may demand the combination of different simulation methods and the synergies between the techniques. The Ururau free and open-source software (FOSS) was applied to implement the DES model. In order to build the dynamic model, we used the software for mechanical design called CAD 3D Software Inventor®. Besides, we also employed the DES model in the test step of a control system in real time. The results of that mechanism implementation enabled the evaluation of different aspects of a typical manufacturing system. Furthermore, the integration between the control system and the DES model allowed validating the logic of the programmable logic controller (PLC). Highlights Mechanism for online communication between a discrete event simulation (DES) software and a system dynamics (SD) software. A free and open-source software (FOSS) was applied to implement the DES model.

Full text
Abstract:
This thesis is aimed at studying the open pit truck- shovel haulage systems using computer simulation approach. The main goal of the study is to enhance the analysis and comparison of heuristic truck dispatching policies currently available and search for an adaptive rule applicable to open pit mines. For this purpose, a stochastic truck dispatching and production simulation program is developed for a medium size open pit mine consisting of several production faces and a single dump site using GPSS/H software. Eight basic rules are modeled in separate program files. The program considers all components of truck cycle and normal distribution is used to model all these variables. The program asks the user to enter the number of trucks initially assigned to each shovel site. Full-factorial simulation experiments are made to investigate the effects of several factors including the dispatching rules, the number of trucks operating, the number of shovels operating, the variability in truck loading, hauling and return times, the distance between shovels and dump site, and availability of shovel and truck resources. The breakdown of shovel and trucks are modeled using exponential distribution. Three performance measures are selected as truck production, overall shovel utilization and overall truck utilizations. Statistical analysis of the simulation experiments is done using ANOVA method with Minitab software. Regression analysis gives coefficient of determination values, R2, of 56.7 %, 84.1 %, and 79.6 % for the three performance measures, respectively. Also, Tukey&rsquo
s method of mean comparison test is carried out to compare the basic dispatching rules. From the results of statistical analysis, it is concluded that the effects of basic truck dispatching rules on the system performance are not significant. But, the main factors affecting the performances are the number of trucks, the number of shovels, the distance between the shovels and dump site, finally the availability of shovel and truck resources. Also, there are significant interaction effects between these main factors. Finally, an adaptive rule using the standardized utilization of shovels and trucks is developed.

Abstract:
The loading cycle in an Open Pit mine is a critical stage in the production process that needs to be controlled in detail for performance optimization. A comprehensive Alert System designed to notify supervisors of cycle times that are below the required performance standards is proposed. The system gives an alert message when one or several trucks are idle or the time of completing production tasks are over a predefined value. This alert is identified by the system and compared with pre-established Key Performance Indicators (KPIs) in order to determine corrective actions. The goal is to determine the strategies that help the production supervisor to optimize the haulage cycle model. A discrete-event simulator has been built in order to analyze different scenarios for route design and queue analysis. A methodology that utilizes different algorithms has been developed in order to identify the least productive times of the fleet. These results are displayed every time the simulation has finished. This research focuses on the optimization of haulage. However, the system is intended for implementation in subsequent stages of the production process, and the resulting improvement could impact mine planning and management as well. Topographic and drilling exploration data from a mine located hypothetically in the state of Arizona, were used to build a block model and to design an open pit; an Arena-based simulation was used to generate operating cycles that represent actual operations (As-Is model). Once the Alert System is implemented, adjustments were applied, and a new simulation was performed taking into consideration these adjustments (To-Be model), including comparative analysis and statistical results.

This dissertation examines the impact of the cost accumulation over the time on the selection of appropriate measures to improve and increase the efficiency of production processes. This effect has been put into the context of lean production and value stream mapping, but there is also examines the impact of job shop schenduling on cost-time investment. As a result of research and original scientific contribution of this thesis two coefficients are proposed: coefficient of investment and coefficient of measure efficiency that can be used in the first place for the selection of appropriate measure for the improvement, and then to define the priorities for implementing the improvement measures.

Abstract:
Computer simulation is becoming increasingly popular among computer network researchers for performance modeling and evaluation of computer and telecommunication networks. This popularity is due to the availability of various sophisticated and powerful simulators, and also because of the flexibility in model construction and validation offered by simulation. While various network simulators (both open source and commercial) exist for modeling and performance evaluation of communication networks, OPNET is becoming popular network simulator as the package is available to academic institutions at no cost, especially OPNET IT Guru. This chapter aims to provide a tutorial on OPNET focusing on the simulation and performance modeling of IEEE 802.11 wireless local area networks (WLANs). Results obtained show that OPNET provides credible simulation results close to a real system.

Abstract:
Communication is a very important area of research in the present era. Expansion of globalization and reduction in the cost of electronic devices has made communication very effective. A large number of researchers from academics and industries are involved in the research on communication and networks. Any novel idea has to be verified on the simulator. A number of simulators are available for network simulations such as Network Simulator (NS2 and NS3), OPNET, NetSim, OMNeT++, REAL, J-Sim and QualNet. NS is an open-source simulation tool that runs on Linux. It is a discreet event simulator for networking research and provides substantial support for simulation of routing, multicast and IP protocols. This chapter provides an overview of NS in a much simpler way. At the completion of this chapter readers will be able to write tcl script to simulate a scenario of network. Every simulation on NS generates a huge trace file; the study of this can be done with the help of AWK script.

Abstract:
Industrial/business processes are an evident example of discrete-event systems which are subject to evolution during life-cycle. The design and management of dynamic workflows need adequate formal models and support tools to handle in sound way possible changes occurring during workflow operation. The known, well-established workflow’s models, among which Petri nets play a central role, are lacking in features for representing evolution. We propose a recent Petri net-based reflective layout, called Reflective Petri nets, as a formal model for dynamic workflows. A localized open problem is considered: how to determine what tasks should be redone and which ones do not when transferring a workflow instance from an old to a new template. The problem is efficiently but rather empirically addressed in a workflow management system. Our approach is formal, may be generalized, and is based on the preservation of classical Petri nets structural properties, which permit an efficient characterization of workflow’s soundness.

Abstract:
Game-based learning and simulation is a powerful mode of learning, used by industries as diverse as aviation and health sciences. While there are many generic Virtual Learning Environments available to further education and higher education in the United Kingdom, there is no widely available open-source Web-based simulation environment for professional learning. The SIMPLE (SIMulated Professional Learning Environment) project has designed, created, implemented and is in the process of evaluating such an environment in a range of disciplinary settings. The simulations that are being created place both undergraduates and postgraduates in a professional context where their work is, as it will be in the workplace, distributed between tools, colleagues, resources, anticipated, and unanticipated problems. One of the key tools that staff will use to create simulations is the “narrative event diagram”, a design tool as well as a means by which the narrative of the simulation is constructed. This chapter will describe the tool, its design history and context, its current use, and next design iteration. In particular it will show the interdisciplinary genesis of the tool’s design, arising from the confluence of computer science, information science, and narrative theory, and its power in designing professional educational simulations.

Abstract:
Abstract Smart Manufacturing advances have recently emerged, focused on the integration of Digital Thread (DTh) and Digital Twin (DT). DTh-DT has been explored in additive manufacturing, aircraft production, and weapons. However, there is still an area of opportunity to explore DTh-DT in collaborative manufacturing cells, layouts, and specifically, in the creation of a system to make an intelligent robotic cell. This work provides a novel approach of a DTh-DT developed to function within a manufacturing robotic cell. A discrete event simulation (DES) was created with open-source programming software, representing the cell. Information is collected from the physical process and sent to a cloud service. The DES request the data from the cloud is executed and the results are received by a database, which works with a Server (Ignition 8.0). The Server receives data and displays results, working as the link between the DT and the Product Lifecycle. This work presents a quick look at a DTh applied to a robotic cell, an approach to a DT, and the use of different types of communications and platforms. The potential benefits of applying this type of configuration in an Industry 4.0 environment are described and critically reviewed.

Abstract:
Abstract In this study, we investigate how the interruptions and non-deterministic operational behavior at the base port affect the installation time and resource utilization. Scenarios such as equipment breakdown are examples of interruption occurrences. The work provides a detailed study of realistic port tasks and scenarios. The operations at the base port and those between the port and the offshore site include fabrication, assembly, load-out, ballasting tasks of the floater, turbine assembly, integrated floater-turbine towing, and hook-up operations. The reference floating substructure, adopted in this study, is an innovative submersible platform concept, developed by CENER for the INNWIND 10MW wind turbine. SimPy, an open-source Python-based package is used to model critical port and installation procedure operations using Discrete Event Simulation. The results are obtained for a range of disruption frequency from 0.0005 to 0.01 (hr−1) and repair times of 8 and 16 (hrs). Results showed an increase in the installation time when disruption frequency and repair time increased. The predicted delay in the installation operations was significant in case of higher disruption frequencies and could reach 21%, compared to the reference case without any failure. Moreover, the utilization of fabrication machines decreased by increasing the disruption rate and repair time. For example, utilization of welding machines for pontoons fabrication reduced by 19% for a high disruption frequency of 0.01 (hr−1), compared to the reference case.
