The high-tech equipment industry brings complex industrial products to the market with high speed, enhanced functionality, a better cost-performance ratio, and greater integration into customer workflows. Driven by digitalization, the complexity of these systems continues to grow steeply. To manage this complexity, continuous innovation in systems engineering methodologies is needed. TNO-ESI targets to 1) create impactful and industrially applicable systems engineering methodologies and 2) provide innovation support to the industry to get these applied in an industrial context. The ESI research program is defined through a roadmapping process that follows two tracks: a roadmap that maps industry needs and related research and development requirements and a roadmap that describes the developments in the expertise areas necessary for addressing these industry needs. In this paper, we describe the ESI mission, our way of working and activities, and explain the roadmapping process and the roadmaps.

高科技设备行业将复杂的工业产品以高速、增强的功能、更好的性价比和更大的集成到客户工作流程中推向市场。在数字化的推动下,这些系统的复杂性继续急剧增长。为了管理这种复杂性,需要在系统工程方法中不断创新。TNO-ESI的目标是:1)创建有影响力的、工业上适用的系统工程方法;2)为行业提供创新支持,使这些方法在工业环境中得到应用。ESI研究计划是通过一个路线图过程来定义的,该路线图遵循两条轨道:一个路线图描绘了行业需求和相关研发需求,一个路线图描述了解决这些行业需求所需的专业领域的发展。在本文中,我们描述了ESI的使命,我们的工作方式和活动,并解释了路线图的制定过程和路线图。

The research and development activities performed by the DLR Institute of Systems Engineering for Future Mobility (DLR-SE) are organized via so-called assets. We present a scenario-based verification and validation process and relate selected research activities.

Verification and validation approaches of automated transportation systems based on driving a certain number of kilometers are infeasible. Therefore, the DLR-SE asset “Scenario-based Verification and Validation of Automated Transportation Systems” investigates methods and prototyping tools for verifying and validating automated transportation systems employing scenarios as the main structuring element to capture complex traffic evolutions. While there are many different approaches, our focus is formally specifying relevant abstract scenarios that are readable by humans while also being machine-readable. This allows us to automatize the verification and validation process, which increases confidence in, for example, the safety of the systems due to a dramatically increased number of executed tests while reducing the manual effort from humans.

由DLR未来移动系统工程研究所(DLR- se)执行的研究和开发活动是通过所谓的资产组织起来的。我们提出了一个基于场景的验证和验证过程,并将选定的研究活动联系起来。以行驶一定公里数为基础的自动运输系统的验证和验证方法是不可行的。因此,DLR-SE资产“基于场景的自动化运输系统的验证和确认”研究了验证和确认自动化运输系统的方法和原型工具,使用场景作为捕获复杂交通演变的主要结构元素。虽然有许多不同的方法,但我们的重点是正式指定相关的抽象场景,这些场景既可以被人类阅读,也可以被机器阅读。这使我们能够自动化验证和确认过程,这增加了对系统安全性的信心,例如,由于执行的测试数量急剧增加,同时减少了人类的手工工作。

As industrial cyber-physical systems grow ever more complex, their software grows naturally and changes continuously. In order to make risk-free changes to their software, it is crucial to understand how the system behaves, and how software changes have an impact on system behavior. We propose a generic two-fold approach to infer state machine models capturing system behavior, and to compare these models to determine and visualize the impact of software changes on system behavior, in a way to make them easily understandable for engineers. Our approach has been applied in the industry at ASML to help prevent software regression problems during critical software redesigns. In that, our approach has been shown to reduce risk and to be valuable.

随着工业信息物理系统变得越来越复杂,它们的软件也在自然发展和不断变化。为了对他们的软件进行无风险的更改,理解系统的行为方式以及软件更改对系统行为的影响是至关重要的。我们提出了一种通用的双重方法来推断捕获系统行为的状态机模型,并比较这些模型以确定和可视化软件更改对系统行为的影响,以一种使工程师易于理解的方式。我们的方法已经在ASML的行业中应用,以帮助防止在关键的软件重新设计期间出现软件回归问题。在这方面,我们的方法已被证明可以降低风险,而且是有价值的。

This paper discusses how digital signoffs can enable new operational paradigms for business operations, digital engineering reviews, and contracts. The paper explains what digital signoffs are in the context of their use with model-based systems engineering methods, which is how this concept and construct has evolved. The paper discusses how they are created in the current toolset. This paper explains the benefits of why digital signoffs are valuable, in addition to where they can be placed within models, and when they might be used. Finally, we discuss how digital signoffs might evolve as add-on capabilities for digital engineering more broadly.

The introduction of automation into technical systems promises many benefits, including performance increase, improved resource economy, and fewer harmful accidents. In particular, in the automotive sector, automated driving is seen as one key element in Vision Zero by eliminating common accident causes such as driving under the influence, reckless behavior, or distracted drivers. However, this is contrasted by new failure modes and hazards from the latest technologies. In this article, we address the problems of finding common sources of criticality for specific application classes and identifying and quantitatively assessing new sources of harm within particular automated driving systems.

将自动化引入技术系统有很多好处,包括提高性能、改善资源经济性和减少有害事故。特别是在汽车领域,自动驾驶消除了酒后驾驶、鲁莽驾驶、分心驾驶等常见事故原因,被视为“零愿景”的关键要素。然而,这与最新技术带来的新失效模式和危害形成了鲜明对比。在本文中,我们解决了寻找特定应用类别的常见临界源以及识别和定量评估特定自动驾驶系统中新的危害源的问题。

Ever-increasing system complexity is challenging for development engineers and service personnel troubleshooting system failures in the field. This paper presents a systematic, scalable approach to attain a diagnostic model. Automatic transformation into computational models is used 1) at design time to improve the diagnosability of the system, and 2) during operation for guided root cause analysis by calculating the most probable failures and suggesting diagnostic procedures based on available data and observations. The approach combines nicely with model-based systems engineering, showing the added value of using diagnostic models both during the design of a system and during operation when the system needs to be diagnosed.

随着系统复杂性的不断增加,开发工程师和服务人员在现场处理系统故障时面临着巨大的挑战。本文提出了一种系统的、可扩展的方法来获得诊断模型。1)在设计时使用自动转换为计算模型来提高系统的可诊断性,2)在运行期间通过计算最可能的故障并根据可用数据和观察建议诊断程序来指导根本原因分析。该方法与基于模型的系统工程很好地结合在一起,显示了在系统设计期间和系统需要诊断时使用诊断模型的附加价值。

The new DLR Institute of Systems Engineering for Future Mobility (DLR SE) opened its doors at the beginning of 2022. As the new DLR institute emerged from the former OFFIS Division Transportation, it can draw on more than 30 years of experience in the research field on safety critical systems. With the transition to the German Aerospace Center (DLR), the institute has developed a new research roadmap focusing on technical trustworthiness for highly automated and autonomous systems, as described in the article “DLR Institute of Systems Engineering for Future Mobility – Technical Trustworthiness as a Basis for Highly Automated and Autonomous Systems” in this journal. In this paper, we describe how the Group Human Centered Engineering (HCE) contributes to this roadmap with our methods of “virtual test drivers” and “virtual co-drivers.”

新的DLR未来移动系统工程研究所(DLR SE)于2022年初开放。由于新的DLR研究所是由前OFFIS运输部门成立的,它可以借鉴30多年来在安全关键系统研究领域的经验。随着向德国航空航天中心(DLR)的过渡,该研究所制定了一项新的研究路线图,重点关注高度自动化和自主系统的技术可信度,如该期刊上的文章“DLR未来移动系统工程研究所-技术可信度作为高度自动化和自主系统的基础”所述。在本文中,我们描述了小组以人为中心的工程(HCE)如何用我们的“虚拟测试驱动程序”和“虚拟辅助驱动程序”的方法为这个路线图做出贡献。

TECoSA – a university-based research center in collaboration with industry – was established early in 2020, focusing on Trustworthy Edge Computing Systems and Applications. This article summarizes and assesses the current trends and drivers regarding edge computing. In our analysis, edge computing provided by mobile network operators will be the initial dominating form of this new computing paradigm for the coming decade. These insights form the basis for the research agenda of the TECoSA center, highlighting more advanced use cases, including AR/VR/Cognitive Assistance, cyber-physical systems, and distributed machine learning. The article further elaborates on the identified strategic directions given these trends, emphasizing testbeds and collaborative multidisciplinary research.
