Geographically distributed agile development may experience a high failure rate due to communication issues, which has a negative influence on project performance. One suggested solution in the literature is to enhance both communication and project performance by implementing agile enterprise architecture. However, the empirical evidence that supports this claim is still scarce. To address this gap, this study empirically explores the role of agile enterprise architecture as an artifact in distributed agile development. The findings of an in‐depth qualitative case study from a dispersed agile development organization that involves teams distributed over three locations are used in this work. Over 2 months, data was gathered by interviewing 12 key members of the team and watching three Sprint sessions of agile software development. Text analysis qualitative approach was used to analyze the data. The findings imply that agile enterprise architecture has a positive effect on distributed agile software development communication, quality, and functionality. Agile enterprise architecture may also support on‐time completion, but a trade‐off with on‐budget may be necessary. These findings provide valuable insights, frameworks, and best practices that support organizations in achieving greater agility, collaboration, and success in their distributed software development initiatives. As this is one of the first studies to look at the influence of agile enterprise architecture on distributed agile software development communication and performance, further research is needed to confirm and expand on the conclusions of this study.

Requirements form the backbone of contracting in acquisition programs. Requirements define the problem boundaries within which contractors try to find acceptable solutions (design systems). At the same time, requirements are the criteria by which a customer measures the extent that their contract has been fulfilled by the supplier. In this context, the quality of a requirement set is determined by the level of contractual safety that it yields. Unfortunately, textual requirements do not provide acceptable levels of contractual safety, as they remain a major source of problems in acquisition programs. Model‐based requirements have been proposed as an alternative to textual requirements, although this promise has not been demonstrated yet. This paper addresses the main question of whether using model‐based requirements improves the contractual safety of acquisition programs compared to using textual requirements. The level of adequate applicability, bounding, necessity, and completeness achieved by model‐based requirements are empirically measured using an experimental study with aerospace engineering and industrial and systems engineering students on a space system application. The results show that model‐based requirements outperform textual requirements in these four variables.

The proliferation of drones in civil and military applications has brought about new challenges in the context of safety and security considerations of operational aspects. The use of small‐ and medium‐sized drones in civilian airspaces even with regulatory approval may not provide guarantees of safety and security. Detection of drones is the first step towards providing a mitigating mechanism for challenges posed by mal‐intentioned drones. Sensors and their characteristics affecting the detection process are discussed. A figure of merit is proposed to compare systems employing these sensors. The key focus of the paper is the examination of the spectrum of drone detection systems (DDS) using a systems‐based approach applied to scenarios. In order to make an equitable comparison between systems, two scenarios are utilized to discuss system characteristics. Next, a survey of DDS in each of these scenarios is performed. Artifacts are analyzed, culling information using the systems model. An approach is proposed to perform evaluation of these artifacts using a scoring mechanism. Simple yet novel measures to assess the information content pertaining to DDS are presented. This approach enables researchers, system architects, system designers, solution providers, and system integrators to be aware of various challenges at the system and subsystem level. The proposed method helps to provide pointers to the literature where information about challenges and specific solutions can be obtained.

Abstract We propose and present a parallelized metric framework for evaluating human‐machine teams that draws upon current knowledge of human‐systems interfacing and integration but is rooted in team‐centric concepts. Humans and machines working together as a team involves interactions that will only increase in complexity as machines become more intelligent, capable teammates. Assessing such teams will require explicit focus on not just the human‐machine interfacing but the full spectrum of interactions between and among agents. As opposed to focusing on isolated qualities, capabilities, and performance contributions of individual team members, the proposed framework emphasizes the collective team as the fundamental unit of analysis and the interactions of the team as the key evaluation targets, with individual human and machine metrics still vital but secondary. With teammate interaction as the organizing diagnostic concept, the resulting framework arrives at a parallel assessment of the humans and machines, analyzing their individual capabilities less with respect to purely human or machine qualities and more through the prism of contributions to the team as a whole. This treatment reflects the increased machine capabilities and will allow for continued relevance as machines develop to exercise more authority and responsibility. This framework allows for identification of features specific to human‐machine teaming that influence team performance and efficiency, and it provides a basis for operationalizing in specific scenarios. Potential applications of this research include test and evaluation of complex systems that rely on human‐system interaction, including—though not limited to—autonomous vehicles, command and control systems, and pilot control systems.

Abstract Electromagnetic Interference and Compatibility (EMI–EMC) are a serious problem in Microelectromechanical Systems (MEMS), and specially in powered by wireless energy transfer MEMS. Most MEMS have dimensions in the order of 1 mm or less, thus, most of the suitable electromagnetic radiation sources have wavelengths larger than this, making isolation of electromagnetic effects very difficult. Model‐Based Systems Engineering (MBSE) can be an excellent tool to deal with EMI—EMC in MEMS during early design phases. In this work, we present a problem‐solving procedure and integration of EMI—EMC in MEMS from a Model‐Based Systems Engineering perspective. This approach is described in detail by a real example using a procedure based on nine steps fully integrated with the proposed systems engineering methodology. For example, the use of context diagrams (IBDs) and N SQUARE charts to describe EMC interactions is explained in detail. The system is formed by a Wireless Power Transfer (WPT) subsystem working near 2.45 or 4.5 GHz coupled to an electromagnetic micromotor. This micromotor contains copper microcoils which can receive electromagnetic radiation directly at the same time that the WPT subsystem. The greatest difficulty is, then, to power the WPT while isolating the micromotor, and optimizing the coupling interface. A summary of the most important EMC concepts and tools are reviewed from the systems engineer perspective and possible problems during the design and testing phases are discussed in detail using the example.

Abstract Developing new mobility services such as electric vehicles and autonomous vehicles services requires not only the interaction and interoperation of independent systems such as electric vehicles, electric infrastructure, or off‐board servers, but also the collaboration of independent business partners, namely, car manufacturers, energy providers, and service providers, developing, managing and operating these systems. Such services show both Product Service Systems and Systems of Systems characteristics and, as such, can be defined as Product‐Service Systems of Systems. While extensive literature exists on developing and managing PSS product and service elements and SoS constituent systems, little research explicitly focuses on PSSoS stakeholders. In particular, the analysis of PSSoS stakeholder business partnerships and involvement in PSSoS development. PSSoS development is seen as the development, operation, and management of constituent systems. This paper contributes to addressing this gap and proposes an approach to manage stakeholder participation in the PSSoS business partnership and PSSoS development.

Abstract Local cities in Japan are struggling with aging and decreasing populations. Elderly people and parents with young children are uniquely challenged when accessing public transportation, a key to increasing their community engagement and improving local cities' sustainability. This research investigates the introduction of new transportation modes and fares on community engagement of both elderly people and parents of young children. An urban systems model which integrates mobility and civic functions is evaluated by agent‐based simulation to analyze various policies’ impacts on community engagement and financial performance. The model is applied to Odawara City, a typical local city of nearly 200,000 people in Japan. For this case study, two policies which strongly subsidize a community bus and partially subsidize a door‐to‐door van were predicted to generate 10% or greater engagement for the elderly without a financial loss compared to the current baseline case. More specifically, community engagement of elderly people and parents with young children are predicted to increase by 11% with positive (0.25 M yen) net present value per person when the fare of community buses is 100 yen and that of door‐to‐door vans is 300 yen. However, no synergistic effect driven by policies favoring elderly people and those favoring parents is found. Still, the measures to support elderly people's transportation accessibility do not harm the parents’ behavior but rather support their daily activities. The method is demonstrated to be useful for designing new mobility policy in light of a specific population with demographic residential distribution and existing transportation network.

Abstract In this work, by constructing a principal‐agent model, we analyze the intrinsic causes of collusion between the government and enterprises, particularly through the central and local governments and resource‐based enterprises. The analysis has been conducted by introducing the public as a third‐party monitoring body to explore the positive role of public participation in preventing collusion between the government and enterprises, and henceforth entailing model analysis and validation with certain examples. The green transformation of resource‐based enterprises is an effective way for their sustainable development, besides being an inevitable requirement for China's high‐quality economic development and ecological civilization construction in the new era. In this perspective, our study reveals that: (1) Government‐enterprise collusion is motivated by the central government's improper assessment and incentive mechanism, besides the information deficit between the central government and the colluding parties. (2) The conditions for government‐enterprise collusion in development remain on the resource‐based enterprises and local governments that face fewer expected penalties than expected benefits, thus resulting in lower collusion risks. (3) Public participation in monitoring can effectively combat the willingness of the local governments and resource‐based enterprises to collude and significantly increase the level of effort of both parties in the green transition. (4) Public monitoring increases the probability of collusion detection, and prompt detection improves the timeliness and effectiveness of punishment. The findings from this study can provide a scientific basis for improving the regulatory system, thus improving public participation and strengthening the penal system.

Abstract A general guide how to implement process safety management (PSM) is missing in the literature. This article provides general procedure to implement PSM which any industry in underdeveloped, developing and developed countries can adopt to start PSM implementation. PSM implementation can be initiated through the proposed framework consisting of four steps: (1) PSM introduction, (2) Assigning departmental wise PSM duties, (3) Trainings and (4) Audits and improvements. Trainings include process hazard analysis (PHA) using Integrated What‐If/HAZOP analysis, quantitative risk assessments using ALOHA or equivalent software, PSM forms developments and other trainings. In a case study, ammonia release is estimated and quantified using ALOHA. Nine various forms for PSM are required to be developed for industry implementing PSM. Various trainings should be arranged including specific learning outcomes and few examples are discussed in this article. An audit scheme is proposed for any new industry implementing PSM. PSM elements implementation sequence is discussed. New established industries can adopt this procedure to implement PSM following suggested forms and sequences, which can help engineers in understanding PSM implementation. This PSM implementation proposed framework is being implemented in the fertilizer industry and caustic industry.

Abstract Pilots use their senses and training to generate situational awareness (SA). They then use this SA to make sound aeronautical decisions. Autonomous vehicles, by contrast, cannot rely on pilot expertise in off‐nominal situations. They must rely on their onboard sensors to build SA of the environment. As these sensors degrade, it is hypothesized that a point exists where the SA generated by these sensors is inadequate to allow the autonomous vehicle to make sound aeronautical decisions. In previous work, a point was defined based on broad assumptions within a modeling and simulation environment (i.e., the error within each sensor was known and not random). This research used a larger data set that contained random errors within the sensors. The data was then used to build predictive equations through a Monte Carlo simulation in the same simulation environment as previous work. While the data showed there was a statistically significant relationship between the error values in each sensor and the fused distance value, the resulting predictive equations were not able to provide adequate SA to make sound aeronautical decisions. This research highlights multiple issues the test and evaluation community will face when trying to develop new techniques for the verification and validation of autonomous systems.

This research highlights multiple issues the test and evaluation community will face when trying to develop new techniques for the verification and validation of autonomous systems.","PeriodicalId":54439,"journal":{"name":"Systems Engineering","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135461887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
