Modeling tools can be used to capture the variety of diagrams and maintain the consistency of elements across the different structural and behavioral representations of the system. Current research is investigating using the XML Metadata Interchange (XMI) standard to convert the diagrammatic information captured in SysML into a format that can be used to produce software code that can then be simulated to ensure conformance with system requirements. The XMI standard can be used as an interim format to migrate the content from a diagrammatic representation, where system elements are sorted by the diagram that contains them, to an object approach, where all elements related to an entity reside in a tree structure below that element. This paper presents a method to ensure the consistency of the XMI representation regardless of whether a functional or physical system engineering approach is used for the design process. This has implications in maintaining the consistency of the XMI file when system development is initiated from a high level of abstraction, followed by iterative addition of detail. The goal is to ensure that XMI file maintains an authoritative representation of the modeled system.","PeriodicalId":384949,"journal":{"name":"2021 IEEE International Systems Conference (SysCon)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117001973","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}

A tractable set of heuristics for handling complexity that can mitigate this risk is consequently highly sought. However, conventional experience-based approaches for identifying complexity handling advice tend to lead to informed but complicated constructs that may be considered over-prescriptive and burdensome for handling complex problems, especially when the need for this support is acute. Further the cacophony of advice, with their tailored lexicons, can cause organizational confusion. This paper explores the development of a simple set of heuristics using an inductive approach that seeks to reduce the decision space and add insight without being overly prescriptive or complicated. An initial set of Heuristics are developed using first-principles. These are then tested and proven by comparison with the dominant discourse in a literature search, to assess if they are simplifying and contributing to established practice, and assessed in a survey to determine if they are useful compared to other similar sets. It is concluded that the proposed set are more useful than similar sets, and that the simplified set of seven heuristics should be developed further to complement other approaches that aim to inform decision-makers in projects, organizations, and society as they seek to handle complexity effectively.","PeriodicalId":384949,"journal":{"name":"2021 IEEE International Systems Conference (SysCon)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124403060","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}

As a new challenge, autonomous systems are developed to be working in a fleet to provide production workflows. Developing such a system-of-systems requires utilizing various software tools to manage the complexity. One task in developing safety-critical products, in general, is to analyze if the applied tools can introduce failures into the final product. Today’s functional safety standards consider only single software tools for analysis. In our industrial work, we can observe a trend towards supporting product lines. A common configurable platform is developed to support a range of different products. Developing such a platform and supporting variability, a toolchain is created where software tools are glued together using scripts to support product lines and automatically generate compiled code. The current functional safety standards do not straight forward support this. This paper discusses how software tools need to support functional safety and show limitations by providing an industrial case. We provide a model-based approach to describe a toolchain and show its application to an industrial case. To analyze potential failures in the toolchain, we utilize the HAZOP method and show its application.","PeriodicalId":384949,"journal":{"name":"2021 IEEE International Systems Conference (SysCon)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131294357","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}

In the teaching process of “electronic circuits”, we have clearly realized that with the rapid development of electronic circuit technology, electronic equipment has become increasingly integrated, electronic design automation (EDA) and the rapid development of various circuit simulation software have greatly simplified the complex circuit analysis and calculations. Because the world is analog, the signals in nature are analog signals, and analog circuits are inseparable from real life. Therefore, we have proposed a comparative teaching strategy of electronic circuit technology with “analogous thinking method”. The so-called analogy thinking refers to the logical reasoning method that transfers the knowledge of one special thing to another special thing based on the similarity or similarity in some aspects between two or two kinds of things. When two types of things are the same or similar in one or some aspects, analogy thinking can be used.

Integration of these activities is advocated by Model-Based Systems Design (MBSD), where a core system model can be enriched with additional capabilities, such as performance analysis or decision-making. The Systems Modeling Language (SysML) is a standard language to utilize model-based design of SoS and create system models, specifying requirements and system constraints. In this work, we focus on integrating decision-making capabilities into SysML to enable system designers to explore alternative solutions that fit the requirements described in SysML. The system model is transformed to a decision model, whose results are automatically incorporated back into the system model. The proposed approach runs iteratively on any typical SysML model and facilitates the designer to explore alternative design solutions, minimizing the manual effort needed to achieve them. As a case study, the approach is applied in the design of a remote patient monitoring system, namely the Remote Elderly Monitoring System (REMS), where the designer decides on a system configuration that covers the needs of the patients.","PeriodicalId":384949,"journal":{"name":"2021 IEEE International Systems Conference (SysCon)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127403168","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}

Recently Machine Learning (ML) techniques have been used to design viable packet classification solutions. However, due to the complexity and dynamic feature of internet traffic, efficient packet classification is still challenging for various machine learning algorithms. In this paper, we propose the adoption of feature selection methods through dimensionality reduction to enhance the classifiers' performance. We evaluated the performance of four well-known classifiers, including K-nearest neighbour (KNN), Support Vector Machines (SVM), Decision Trees (DT), and Logistic Regression (LR) with and without feature selection. We used two feature selection methods, including principal component analysis and Autoencoder. Experimental analysis is performed on real network traffic datasets with binary and multi-class categories. We assessed each classifier's performance using precision, recall, f-score, accuracy, and ROC. Experimental results show that the Precision, Recall, and F-score for the Multi-class problem are improved by 4.7 %, 6%, and 9%, respectively, after adopting either PCA or Autoencoder methods. The classification accuracy is also improved by up to 13%. We can also conclude that Autoencoder performed better for the KNN and LR, while PCA achieved comparable results for both the SVM and DT classifiers.","PeriodicalId":384949,"journal":{"name":"2021 IEEE International Systems Conference (SysCon)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131955174","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}

There is a need to explore the adoption of virtual computer-based training mediums which will enable new nurses and others to be trained in safe and efficient procedures involving patients during this pandemic period. In this paper, the design of a VR-based simulator based on Human-Centered Computing (HCC) principles are discussed. The role of HCC factors such as affordance and cognitive load on the comprehension and scene understanding of nurses during training and the acquisition of knowledge of safety procedures and detailed steps (pertaining to nasal sample collection and use of ventilators on patients) has been studied with the involvement of nurse and nurse trainee participants. Adoption of a participatory design approach involving experts (nurses, doctors involved in covid-19 testing and treatment) has provided a foundational basis for the design of the training environments and assessment activities. Formal information-centric process models of the nasal swabbing procedures and ventilator hookup tasks were created using the engineering Enterprise Modeling Language (eEML).
