Abstract The concept of Reference Architectures is novel in the business world. However, many architects active creation complex systems frequently use term Architecture . Yet, these experienced do not collectively have a consistent notion what constitutes Architecture, value maintaining best approach to visualizing most appropriate level abstraction, and how should an architect make their work? This paper examines current driving forces behind development them come collective conclusion on...
Abstract Engineered solutions are becoming more complex and multi‐disciplinary in nature. This evolution requires new techniques to enhance design analysis tasks that incorporate data integration interoperability across various engineering tool suites spanning multiple domains at different abstraction levels. Semantic web technologies (SWT) offer benefits as well other opportunities reasoning knowledge represented disparate models. paper introduces the digital framework for (DEFII)...
Scientific community understanding of the variance in severity infectious disease like COVID-19 across patients is an important area focus. The article presents innovative voting ensemble GenoCare Prognosticator (GCP) model that incorporates XGBoost and Random Forest classifiers, two cutting-edge machine learning approaches. A large dataset medical covariates gender age along with biological WES (Whole Exome Sequencing) data was used to train these models. Five-fold stratified...
ABSTRACT The systems engineering and product development community can benefit from a methodology that significantly reduce the likelihood of rework when decisions are made within context moderate to high information uncertainty. This condition is predominant in concept design stage early lifecycle stages data scarce, model fidelity low, stakeholder needs requirements expected change. Several quantitative methods used develop, reason, narrow alternatives have been vulnerable requirement...
Abstract While much has been written about patterns in software engineering, little their application to systems architecting. This paper provides a discussion of and potential applicability complex system A historical introduction the concept is provided along with evolution from domain civil architecture other engineering disciplines domains. The relevance architecting then examined. Research regard developing pattern form for documenting presented, this demonstrated on command control...
This paper will propose to do as von Bertalanffy once did, and that is draw on the biological sciences, now hugely advanced beyond ever imagined by his peers, use its findings, architectures, emergent behaviors argue for a biology of system systems (SoS). We seek science approach we believe provide richer insight into SoS failure, "health" maintenance, repair, replication, growth, mutation-all those features evolution which constantly challenge us which, thus far, have only been able explain...
The purpose of this paper is to evaluate alternative networking concepts (standards and protocols), with a particular emphasis on comparing ARINC 664 network standard legacy avionics networks. conclusions comparison are reinforced an example solution for the architecture using Avionics Full- Duplex Switched Ethernet (AFDX) protocol. modules (hardware software) applications aircraft crucial, often new designs upgrades rely architectures. In past, such systems in defense have been successfully...
Abstract Systems engineers have always been concerned with the problems surrounding complex systems. An evolutionary class of systems called Complex Adaptive (CAS) is even more relevant today as we struggle to understand and cope often undesirable emergence effects some these systems, evidenced by recurring financial sociopolitical crises. A key characteristic CAS a large, diverse, sometimes unknown set interactions both internally across system boundary. For purpose managing this complexity...
Reliability, Maintainability and Supportability (R, M S) are the main drivers of system operational effectiveness (SOE). New procurement strategies have been developed by both public private sectors to focus on R, S characteristics inherent design a system. One such strategy known as Performance Based Logistics (PBL) has gained popularity due its success in improving In PBL contract customer buys performance, typically measured using metrics, instead contracting for specified collection...
Abstract In military, civil, and commercial systems there exists a need to affordably manage the operational effectiveness of system interest through acquisition stages its life cycle. Once design is baselined instantiated, then challenge during development, production, utilization cycle maintain currency physical baseline facilitate affordable support. essence, must adapt potentially frequent asynchronous obsolescence constituent elements, requirements growth (driven by environmental...
Identification of a need or deficiency triggers conceptual system design. The first step in design is to analyze and translate the into specific qualitative quantitative customer requirements. Design methods such as quality function deployment (QFD), parameter taxonomies input/output matrices provide useful framework for this translation. Well defined unambiguous requirements enhance communications can potentially reduce number 'detours' during subsequent development phases. However,...
Abstract Product development efforts now more than ever are in need of methodologies that can address the challenges increased system complexities, shortening time to market, demands mass customization, market instabilities, geographical barriers, improved innovation, and adaptability emerging technologies. To these most companies will make key decisions early product life‐cycle. In this phase there high levels information uncertainty ambiguity. Under circumstances many converge too a point...
The SARS-CoV-2 virus, which induces an acute respiratory illness commonly referred to as COVID-19, had been designated a pandemic by the World Health Organization due its highly infectious nature and associated public health risks it poses globally. Identifying critical factors for predicting mortality is essential improving patient therapy. Unlike other data types, such computed tomography scans, x-radiation, ultrasounds, basic blood test results are widely accessible can aid in mortality....
Do system requirements depend on each other? Or, do live in an isolated world of their own and act independently by being completely oblivious to the presence other requirements? Since a singular requirement does not convey entire story, it supports belief that other. If so, then dependant themselves converge into network, object satisfies systemic criteria? answer is affirmative, we assert relationships between (depicted as nodes network) must exist, so 'whole' emerges, may be considered...
The First International Conference in Systems and Network Medicine gathered together 200 global thought leaders, scientists, clinicians, academicians, industry government experts, medical graduate students, postdoctoral scholars policymakers. Held at Georgetown University Center Washington D.C. on September 11-13, 2019, the event featured a day of pre-conference lectures hands-on bioinformatic computational workshops followed by two days deep diverse scientific talks, panel discussions with...
:The ability to assess systems engineering effectiveness within organizations is receiving increasing emphasis. Most of the published research has been generic and domain independent. This article describes a technique (1) estimate cost schedule projects at an early concept phase, (2) determine efficiency using methods practices on large integration in information technology (IT) sector. A method based complexity point developed discussed. validated number IT projects. Resulting observations...
