Companies in the high-tech equipment industry are continuously looking for ways to optimize their business. A notoriously difficult part of optimizing is the R&D activities, as risks and uncertainties are inherent. In our experience, creating and using a reference architecture for a product or portfolio to guide future developments is a good way to improve R&D effectiveness and efficiency. But developing a reference architecture by capturing the relevant information and establishing the structure, the models and their interrelations, the tools, and secondly, getting clarity on how to use such reference is not easy. In this article, we describe a method to ‘distill’ a reference architecture using the knowledge built-up in years of developing products and using the customer and business values to capture the key architectural decisions for future products. We explain the purpose and usage of a reference architecture and how to organize it. The experiences obtained in Thermo Fisher Scientific have proven the importance and practicality of this approach.

高科技设备行业的公司一直在寻找优化业务的方法。众所周知,优化中最困难的部分是研发活动,因为风险和不确定性是固有的。根据我们的经验,为产品或投资组合创建和使用参考体系结构来指导未来的开发是提高研发有效性和效率的好方法。但是,通过获取相关信息和建立结构、模型及其相互关系、工具,以及其次,明确如何使用这些参考来开发参考体系结构并不容易。在本文中,我们描述了一种“提炼”参考体系结构的方法,该方法使用多年来开发产品积累的知识,并使用客户和业务价值来捕获未来产品的关键体系结构决策。我们解释了参考体系结构的目的和用法,以及如何组织它。赛默飞世尔的经验证明了这种方法的重要性和实用性。

Network softwarization has revolutionized the architecture of cellular wireless networks. State-of-the-art container based virtual radio access networks (vRAN) provide enormous flexibility and reduced life-cycle management costs, but they also come with prohibitive energy consumption. We argue that for future AI-native wireless networks to be flexible and energy efficient, there is a need for a new abstraction in network softwarization that caters for neural network type of workloads and allows a large degree of service composability. In this paper we present the NeuroRAN architecture, which leverages stateful function as a user facing execution model, and is complemented with virtualized resources and decentralized resource management. We show that neural network based implementations of common transceiver functional blocks fit the proposed architecture, and we discuss key research challenges related to compilation and code generation, resource management, reliability and security.

网络软件化已经彻底改变了蜂窝无线网络的架构。最先进的基于容器的虚拟无线接入网络(vRAN)提供了巨大的灵活性,降低了生命周期管理成本,但它们也带来了令人难以承受的能源消耗。我们认为,为了使未来的人工智能原生无线网络更加灵活和节能,需要在网络软件化中引入新的抽象,以满足神经网络类型的工作负载,并允许很大程度的服务可组合性。在本文中,我们提出了NeuroRAN架构,它利用有状态功能作为面向用户的执行模型,并辅以虚拟化资源和分散的资源管理。我们展示了基于神经网络的通用收发器功能块的实现符合所提出的架构,并讨论了与编译和代码生成,资源管理,可靠性和安全性相关的关键研究挑战。

Over the past five years, with funding from the US Air Force and the US Space Force, SERC researchers at the University of Southern California's Information Sciences Institute have undertaken a series of case studies that have focused on the introduction of agile and DevSecOps practices into a space-based software-only acquisition environment. These studies have identified best practices and revealed useful lessons learned. While the initial baseline DoDI 5000.02 project was entirely waterfall-based, subsequent projects have introduced agile/DevSecOps methods in progressively increasing levels, with the second project consisting of a roughly a 50/50 hybrid agile/waterfall mix and with the current project consisting of an approximately 70/30 hybrid agile/waterfall mix effort. All projects exhibit similar code complexity and size.

在过去的五年中,在美国空军和美国太空部队的资助下,南加州大学信息科学研究所的SERC研究人员进行了一系列案例研究,重点是将敏捷和DevSecOps实践引入天基软件采办环境。这些研究确定了最佳做法,并揭示了从中吸取的有益经验教训。虽然最初的基线DoDI 5000.02项目完全是基于瀑布的,但随后的项目逐渐增加了敏捷/DevSecOps方法的级别,第二个项目由大约50/50的敏捷/瀑布混合组成,而当前的项目由大约70/30的敏捷/瀑布混合组成。所有项目都表现出相似的代码复杂度和大小。

Modern engineered systems, and learning-based systems, in particular, provide unprecedented complexity that requires advancement in our methods to achieve confidence in mission success through test and evaluation (T&E). We define learning-based systems as engineered systems that incorporate a learning algorithm (artificial intelligence) component of the overall system. A part of the unparalleled complexity is the rate at which learning-based systems change over traditional engineered systems. Where traditional systems are expected to steadily decline (change) in performance due to time (aging), learning-based systems undergo a constant change which must be better understood to achieve high confidence in mission success. To this end, we propose pairing Bayesian methods with systems theory to quantify changes in operational conditions, changes in adversarial actions, resultant changes in the learning-based system structure, and resultant confidence measures in mission success. We provide insights, in this article, into our overall goal and progress toward developing a framework for evaluation through an understanding of equivalence of testing.

现代工程系统,特别是基于学习的系统,提供了前所未有的复杂性,需要我们在方法上取得进步,通过测试和评估来实现任务成功的信心(T&E)。我们将基于学习的系统定义为包含整个系统的学习算法(人工智能)组件的工程系统。这种无与伦比的复杂性的一部分是基于学习的系统相对于传统工程系统的变化速度。由于时间(老化),传统系统的性能预计会稳步下降(变化),而基于学习的系统则会经历不断的变化,必须更好地了解这种变化,才能对任务的成功抱有高度的信心。为此,我们提出将贝叶斯方法与系统理论相结合,量化作战条件的变化、对抗行动的变化、基于学习的系统结构的由此变化,以及由此产生的任务成功信心措施。在这篇文章中,我们提供了对我们的总体目标的见解,以及通过理解测试的等价性来开发评估框架的进展。

Kara Pepe, Nicole Hutchison

Artificial intelligence (AI) and machine learning (ML) technology are becoming increasingly critical in systems: both to provide new capabilities and in the practice of systems engineering itself, especially as digital transformation improves the automation of many routine engineering tasks. The application of AI, ML, and autonomy to complex and critical systems encourage the development of new systems engineering methods, processes, and tools. This article highlights a series of workshops conducted jointly by the US Army Combat Capabilities Development Command Armaments Center (CCDC AC) Systems Engineering Directorate and the Systems Engineering Research Center (SERC). These workshops focus on the relationships between AI and systems engineering and elicit input from hundreds of stakeholders across government, industry, and academia. They also provide critical direction to the SERC's research roadmap on AI/autonomy as it looks towards the long-term outcome of “human-machine co-learning.” Though the workshops are US-centric, the lessons and insights gained are applicable globally.

人工智能(AI)和机器学习(ML)技术在系统中变得越来越重要:无论是提供新功能还是在系统工程本身的实践中,特别是随着数字化转型提高了许多常规工程任务的自动化程度。人工智能、机器学习和自主性在复杂和关键系统中的应用鼓励了新的系统工程方法、过程和工具的发展。本文重点介绍了由美国陆军作战能力发展指挥军备中心(CCDC AC)系统工程理事会和系统工程研究中心(SERC)联合举办的一系列研讨会。这些研讨会关注于人工智能和系统工程之间的关系,并从政府、工业和学术界的数百个利益相关者那里获得输入。它们还为SERC的人工智能/自主研究路线图提供了关键方向,因为它着眼于“人机共同学习”的长期成果。虽然这些研讨会以美国为中心,但所获得的经验和见解适用于全球。

The newly established Institute of Systems Engineering for Future Mobility within the German Aerospace Center opened its doors at the beginning of 2022. Emerging from the former OFFIS Division Transportation after a two-year transition phase, the new institute can draw on more than thirty years of experience in the research field of safety-critical systems. With the transition to the DLR, the institute's new research roadmap focuses on technical trustworthiness for highly automated and autonomous systems. Within this field, the institute will develop new concepts, methods, and tools to support the integration and assurance of technical trustworthiness for automated and autonomous systems during their whole lifecycle – from the early development through verification, validation, and operation to updates of the systems in the field.

在德国航空航天中心新成立的未来移动系统工程研究所于2022年初开业。经过两年的过渡阶段,新的研究所从前OFFIS部门运输中脱颖而出,可以借鉴在安全关键系统研究领域三十多年的经验。随着向DLR的过渡,该研究所的新研究路线图侧重于高度自动化和自主系统的技术可信度。在该领域,该研究所将开发新的概念、方法和工具,以支持自动化和自主系统在其整个生命周期中的集成和技术可靠性保证——从早期开发到验证、确认和操作,再到该领域系统的更新。

Automotive software is undergoing a rapid change toward artificial intelligence and towards more and more connectedness with other systems. For both, an incremental design paradigm is desired, where the car's software is frequently updated after production but still can guarantee the highest automotive safety standards. We present a design flow and tool framework enabling a DevOps paradigm for automotive software development. DevOps means that software is developed in a continuous loop of development, deployment, usage in the field, collection of runtime data and feedback to the developers for the next design iteration. The software developers get support in defining, developing, and verifying new software functions based on the data gathered in the field by the previous software generation. The software developers can define contracts describing the time and resource assumptions on the integration environment and guarantees for other dependent software components in the system. These contracts allow a composition of software components and proof obligations to be discharged at design time through virtual integration testing and runtime through continuous monitoring of assumptions and guarantees on the software component's interfaces. An update package, consisting of the software component and its contracts, is then automatically created, transferred over the air, and deployed in the car. Monitors derived from the contracts allow for supervising the system's behavior, detecting failures at runtime, and annotating the situation to be included in a data collection, fueling the next design iteration.

汽车软件正经历着向人工智能和越来越多地与其他系统连接的快速变化。对于两者来说,都需要一种渐进式的设计范式,即汽车的软件在生产后经常更新,但仍然可以保证最高的汽车安全标准。我们提出了一个设计流程和工具框架,使汽车软件开发的DevOps范式成为可能。DevOps意味着软件是在开发、部署、现场使用、收集运行时数据和向开发人员反馈下一次设计迭代的连续循环中开发的。软件开发人员在定义、开发和验证基于上一代软件在该领域收集的数据的新软件功能方面得到支持。软件开发人员可以定义契约,描述对集成环境的时间和资源假设,以及对系统中其他相关软件组件的保证。这些契约允许软件组件的组合和证明义务在设计时通过虚拟集成测试和运行时通过对软件组件接口上的假设和保证的持续监控来实现。然后,由软件组件及其契约组成的更新包被自动创建,通过空中传输,并部署在汽车中。来自合同的监视器允许监督系统的行为,在运行时检测故障,并注释要包含在数据集合中的情况,为下一个设计迭代提供动力。

Monitors derived from the contracts allow for supervising the system's behavior, detecting failures at runtime, and annotating the situation to be included in a data collection, fueling the next design iteration.</p>\u0000 </div>","PeriodicalId":13956,"journal":{"name":"Insight","volume":"25 4","pages":"85-88"},"PeriodicalIF":1.1,"publicationDate":"2023-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86465900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
