However, manned vehicles are still needed to transport materials and personnel in the tunnels, which requires practices that may diminish autonomy benefits. Thus, both fleets shall be efficiently mixed to maximize the autonomy potential. In addition, sufficient safety shall be demonstrated for operations approval. This paper proposes a strategy to populate a GSN (Goal Structuring Notation) structure to argue for the sufficient safety of mixed traffic operations in underground mining. Our strategy considers SoS (System of Systems) concepts to describe the operations baseline and the initial argumentation line, i.e., risk reduction mitigation strategies for existing SoS components. Such a strategy is further detailed with risk reduction mitigation arguments for control systems. Mitigation strategies at both levels are derived from safety analysis supported by STPA (System-Theoretic Process Analysis), a safety analysis technique that aligns well with the SoS perspective. We also incorporate regulatory frameworks addressing machinery to align the arguments with mandatory statements of the machinery directive. Our strategy combines SoS concepts with analysis techniques and regulatory frameworks to facilitate safety case argumentation for operations approval in the European mining context.","PeriodicalId":181642,"journal":{"name":"2023 18th Annual System of Systems Engineering Conference (SoSe)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130464487","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}

{"title":"Complexity in the delivery of product passports: a system of systems approach to passport lifecycles","authors":"Paul D. Timms, M. King","doi":"10.1109/SoSE59841.2023.10178575","DOIUrl":"https://doi.org/10.1109/SoSE59841.2023.10178575","url":null,"abstract":"Product passports are an emerging data innovation positioned as an information tool to enable sustainable and circular futures, where such futures are delivered through increased and more precise information about resources, products, and processes across the “product lifecycle”. But this is a complex problem space where traditional linear product lifecycles do not reflect the nature and lifespan of articulated passport information types. This is because passports are not records of products per se (as the name would suggest) but descriptions of the lifecycle activities associated with those individual product assets, collating data points throughout engineering, use, re-use, and end-of-life processes. Unfortunately, this distinction is often overlooked, given the limited attention to the life of a product passport after manufacture and the differences between product passports and product passport systems. This paper presents a generic ‘lifecycle model for a passport’ as an information system of systems comprised of nine constituent lifecycle viewpoints. It builds upon recent research developing the idea of a digital product passport ‘ecosystem’, focusing on the specific application of the battery passport. Each lifecycle viewpoint is framed as a distinct ‘information system of systems' within a broader information ecosystem. Established concepts within the systems discipline are used to show inherent differences in each viewpoint's spatial and temporal focus and explain the relationships between each lifecycle viewpoint, thus articulating the parent-child relationships of different datasets and the necessary interoperability between information domains and engineering activities. The resultant model highlights the likely evolution of data requirements over an individual passport's lifespan, thus contributing to a possible future vision for an interoperable battery passport ecosystem. Furthermore, it is suggested that this lifecycle model can inform the evaluation and discussion of “completeness” for any passport-type system, given its adoption of interdisciplinary systems domain techniques and concepts, helping shape future exploration of the circular economy capability space.","PeriodicalId":181642,"journal":{"name":"2023 18th Annual System of Systems Engineering Conference (SoSe)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115146300","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 challenge addressed in this paper pertains to the development and implementation of effective governance for this complex SoS. Governance, in this context, refers to the comprehensive set of rules, policies, and criteria that organize and drive decision-making processes to achieve the Depollution Network's missions and objectives. The proposed organizational and governance model is inspired by the principles underlying both system of systems management and business modelling. These principles are tailored specifically to the unique context of a business network engaged in depollution and dismantling efforts. By integrating these perspectives, this paper aims to offer a more relevant and robust approach to governing Depollution Network (DN) in order to enhance efficiency and overall performance.","PeriodicalId":181642,"journal":{"name":"2023 18th Annual System of Systems Engineering Conference (SoSe)","volume":"2003 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128680180","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 assist, the INCOSE Complex Systems Working Group seeks to create and develop a useful set of SysE heuristics that can provide guidance. Analysis of an initial set of heuristics, identified using complex(ity) search terms across an INCOSE database, indicated that they did not sufficiently cover the wider system of interest and culture aspects and required further independent review and usage to become established. This paper addresses these concerns by using additional search terms across the INCOSE database and reporting the findings of an independent SysE team review of the original and newly identified heuristics. Using this approach, an additional 15 heuristics have been added, and modifications to both sets have been identified and agree with an independent focus group. It is concluded that the heuristics identified are useful and have resolved the breadth issues. However, to ensure the heuristics are more useful, additional work is required to rationalize the set from 33 heuristics, explain the rationale for the additional heuristics, and new methods need to be explored to aid the recall of the right heuristic, such as categorisation.","PeriodicalId":181642,"journal":{"name":"2023 18th Annual System of Systems Engineering Conference (SoSe)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132848521","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}

Starting from the raw data which were daily extracted from sensors, an analysis of the collected signals is performed to help decision-making concerning its maintenance. In the case study related to a door system in a bus, the proposed method can recognize the different damage states analysing the input parameters: temperature, pressure, and humidity of door systems.

Hafid","doi":"10.1109/SoSE59841.2023.10178665","DOIUrl":"https://doi.org/10.1109/SoSE59841.2023.10178665","url":null,"abstract":"“System of Systems” (SoS) refers to a collection of individual systems that work together to achieve a common goal. SoS often involve complex interactions and interdependencies between systems, and as a result, they can be challenging to design, manage, and maintain. Resilience is the ability of a system to withstand and recover from disruptive events. When considering a system of systems, resilience becomes a key factor as disruptions in one system may have a cascading effect on the other systems. To ensure resilience in such complex environment, constraint programming (CP) can be used to model and optimize the system's behavior, and to find the optimal configuration that satisfies all constraints. This approach can help identify the best reconfiguration options that meet specific objectives, such as maximizing system performance, minimizing costs, or minimizing risks. Compared to previous works that primarily performs SoS reconfiguration by moving the failed system into a degraded operating mode to maintain acceptable functioning, this work focuses on a type of system failure, so that degraded mode is not possible. A constraint-based reconfiguration approach is developed, allowing the system to continue operating efficiently in the face of unexpected events.

The main goal of the proposed model is to avoid overlapping flight zones of aircraft on approach for takeoff or landing.","PeriodicalId":181642,"journal":{"name":"2023 18th Annual System of Systems Engineering Conference (SoSe)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127126670","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}

Unfortunately, the security of an SoS cannot be guaranteed by separately addressing the security of each CS. Security must also be addressed at the SoS level. This paper reviews some of the most prominent cybersecurity risks within the SoS research field and combines this with the cyber and information security economics perspective. This sets the scene for a structured assessment of how various cyber risks can be addressed in different SoS architectures. More precisely, the paper discusses the effectiveness and appropriateness of five cybersecurity policy options in each of the four assessed SoS archetypes and concludes that cybersecurity risks should be addressed using both traditional design-focused and more novel policy-oriented tools.","PeriodicalId":181642,"journal":{"name":"2023 18th Annual System of Systems Engineering Conference (SoSe)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125362777","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 meet these challenges, many are turning to Industry 4.0 technology to be more resilient, sustainable and efficient. However, there is a risk of mass adoption failure due to products being developed in silos that impact product usability, availability, interoperability and adaptability. The financial viability of Industry 4.0 technology adoption is also challenging for many crops. This is due to the high variety of activities being required for only short periods of time during the growing season. This paper proposes a Horticulture System of Systems (SoS) approach, that goes beyond data interoperability, to promote the collaboration of individual constituent systems into an equitable, affordable, optimised ecosystem. The paper utilises systems thinking to identify inter-dependencies and potential opportunities (use cases) to leverage Industry 4.0 technology within the kiwifruit industry in New Zealand. A Modular Agritech Systems for Horticulture (MAS-H) concept is proposed focusing on re-usable sensing, image recognition, robotics hardware and software on-orchard, along with an industry-good data gateway and digital twin. The paper concludes with the implementation of two case studies: Kiwifruit Human Assisted Harvesting and Labour Decision Support (flower bud thinning). Future research will focus on the validation of the MAS-H concept within the kiwifruit industry, including application in other use cases and the addition of a sustainable support system. In parallel, the potential application of SoS across the wider horticulture industry will be investigated.","PeriodicalId":181642,"journal":{"name":"2023 18th Annual System of Systems Engineering Conference (SoSe)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125006768","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}

Another growing challenge for military platforms is achieving interoperability within a system of systems context, as they are becoming more distributed and delivering new and expanded capabilities. To address these engineering and integration issues, an approach gaining popularity over the last decades, is a move toward standardization delivered through Open Architectures as part of the information structure of these complex systems. This paper presents a synthesis of Open Architecture standards to help readers understand how this approach has been applied over the years and the current practice. Over 80 standards or associated initiatives have been identified and analyzed from multiple domains (land, maritime, air), various nations, and consortia. Analysis shows there are similar and overlapping initiatives, but also discontinuities in some programs, which may reduce the credibility of the approach and hinder the adoption of open architecture standards if the implementation is not adequately addressed and contextualized. Thus, this paper presents the initial findings of ongoing research on the principles of implementing open architectures, to provide programme managers with the information and parameters required to select or tailor the most appropriate approach for their needs.","PeriodicalId":181642,"journal":{"name":"2023 18th Annual System of Systems Engineering Conference (SoSe)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125388035","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}
