As a result, modeling tools are now very specific to their respective domains and are growing more and more incongruous with each other. This calls for a way to integrate multiple modeling tools in the effort to create a single, large model capable of encapsulating data from multiple, different models. Thus, in this paper, different methods to perform an integration with Systems Modeling Language (SysML) and a simulation tool were identified, described and evaluated. Then, a new method was developed and discussed. Finally, the new method was demonstrated by developing a SysML executable model of a simple two-room house. Using the Functional Mock-up Interface (FMI) standard, the SysML model is integrated with a Modelica model, and a simulation is run in Simulink. Finally, a tradeoff analysis was performed for the purpose of design space exploration.","PeriodicalId":192753,"journal":{"name":"2018 IEEE International Systems Engineering Symposium (ISSE)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125192142","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}

Instead of having a redundant E/E-architecture we propose a dynamically reconfigurable one. With this paper we introduce two new simulation techniques on how to extract two important values for reconfiguration. The approach is based on an example for the loss of steering control functionality. The first value is the overall system reconfiguration time that is recognized by the human driver in case of a loss of steering control functionality. The second value is the maximum reconfiguration time possible to still perform a given maneuver. The results of both values are compared to a previous study. This leads to end-to-end reconfiguration times for future development of fail-operational self-reconfigurable real-time automotive embedded systems. A method for simulating loss of functionality and deriving specification relevant data is given to assist the automotive industry reaching fail-operational systems. It will also help in introducing dynamical reconfiguration for a fail-operational automotive E/E-architecture as the next step.","PeriodicalId":192753,"journal":{"name":"2018 IEEE International Systems Engineering Symposium (ISSE)","volume":"612 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113996371","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}

These innovations imply different changes in various engineering domains (i.e. product development, manufacturing systems and automated Production Systems). To cope with these changes, various approaches are developed within each domain. On the contrary, these domains are tightly coupled and thus, an integrated view often impedes successful management of changes. Building on the work of an interdisciplinary research collaboration, we present various methods and models addressing change management. Subsequently, we classify these approaches and explore how an interdisciplinary view can enrich integrated change management. Finally, we derive a representative use case, which will serve as demonstration case for the obtained scientific results and practical tool in the context of interdisciplinary change management for technical PSS.","PeriodicalId":192753,"journal":{"name":"2018 IEEE International Systems Engineering Symposium (ISSE)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126278606","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}

When machines are automated and utilized in system-of-systems, a thorough analysis of potential critical scenarios is necessary to derive appropriate design solutions that are safe as well. Hazard analysis methods like PHA, FTA or FMEA help to identify and follow up potential risks for the machine operators or bystanders and are well-established in the development process for safety critical machinery. However, safety certified individual machines can no way guarantee safety in the context of system-of-systems since their integration and interactions could bring forth newer hazards. Hence it is paramount to understand the application scenarios of the system-of-systems and to apply a structured method to identify all potential hazards. In this paper, we 1) provide an overview of proposed hazard analysis methods for system-of systems, 2) describe a case from construction equipment domain, and 3) apply the well-known System-Theoretic Process Analysis (STPA)f to our case. Our experiences during the case study and the analysis of results clearly point out certain inadequacies of STPA in the context of system-of-systems and underlines the need for the development of improved techniques for safety analysis of system-of-systems.","PeriodicalId":192753,"journal":{"name":"2018 IEEE International Systems Engineering Symposium (ISSE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129430586","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}

Necessitating organizations to respond on several fronts in order to effectively manage the application and adoption of cutting-edge technical standards and systems engineering. These challenges have been identified as forces that are shaping modern industries and defining the systems engineering roadmap. This paper sets out to describe and document this system engineering metamorphosis by leveraging its heritage, as well as past and present standards. It discusses the forces behind this evolution and introduces key SE standards and materials such as ISO/IEC/IEEE 15288 (life cycle processes), ISO/IEC/IEEE 29148 (requirements processes) and the INCOSE Systems Engineering handbook which explain the processes related to systems engineering. These specific standards provide an elaboration of processes that benefit enterprises dealing with products and services of high complexity. This paper also explains the key concepts and tools such as the ‘tailoring’ of processes through a framework and utilization of the input-process-output (IPO) diagram. By providing a snapshot of current challenges in society this paper also aims to provide insight of what can be expected for SE centred and steered design typically encountered in high-tech integrators/manufacturers. In conclusion, organizations, including those in the biomedical and healthcare sectors, that effectively leverage SE standards and the INCOSE SE Handbook can be better positioned to develop safe(r) and more effective products once these approaches become common practice.","PeriodicalId":192753,"journal":{"name":"2018 IEEE International Systems Engineering Symposium (ISSE)","volume":"164 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116297093","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}
