“…A U.S. Department of Defense study in 2008 divides the spectrum of SoS types into four categories based on the relationships between the SoS's constituent systems. From loosely coupled to tightly coupled, the SoS categories are 16–18 : Virtual: constituent systems lack a central management authority and a centrally agreed upon purpose, Collaborative: constituent systems interact more or less voluntarily to fulfill agreed upon central purposes, Acknowledged: constituent systems have recognized objectives, a designated manager, and resources; and retain their independent ownership, objectives, funding, development, and sustainment approaches, Directed: constituent systems form an integrated SoS built and centrally managed to fulfill specific purposes. …”

Assessing the impact of natural disasters and manmade incidents against critical infrastructure systems is important and challenging. As critical infrastructure sectors become more interdependent, a method is needed to assess how disruptions to one sector affect other sectors. This need is particularly significant in the case of critical national supply chains which have not received the same attention as other critical infrastructure systems. This research develops a methodology for performing supply chain impact assessments by integrating model‐based systems engineering (MBSE) with discrete event simulation (DES). SysML models capture the supply chain structure and critical infrastructure interdependencies. Simulation of the supply chain model subjected to external constraints identifies the impacts from critical infrastructure disruptions. This approach enables researchers and public policy planners to assess critical supply chain risks associated with current infrastructure implementations, and to conduct what‐if analyses on alternative solutions. Application of this methodology to assess the natural disaster impacts on an urban food supply system demonstrates the effectiveness of modeling and simulation for evaluating the impacts of critical infrastructure disruptions on a wide range of critical supply chains. Future research should apply this methodology to different national supply chains and investigate additional critical infrastructure interdependency linkage mechanisms.

“…26 Starting with the USS VIRGINIA, as a result of political, economic and performance considerations these independent systems were converged into the SWFTS SoS. 27 During this convergence both the SoS as a whole and many of the constituent systems have incorporated open systems architecture principles and business practices. 28 In the SoS taxonomy, 13 SWFTS is an Acknowledged SoS.…”

The Submarine Warfare Federated Tactical Systems (SWFTS) is a rapidly evolving combat system of systems (SoS) product family. Managing the annual baseline updates requires processing thousands of baseline change requests, then coordinating and verifying their implementation. The complexity of this effort, which involves well over ten million source-lines-of-code (SLOC) as well as Commercial-Off-the-Shelf (COTS) and military-unique hardware, is compounded by being deployed in ten variants.After a feasibility study in 2010 the SWFTS systems engineering and integration program started a transition from traditional requirements database and documentcentric systems engineering (DCSE) to a model-based systems engineering (MBSE) process. At that time there was little solid evidence in the literature for a positive Return on Investment (ROI) for moving from DCSE to MBSE.Applying MBSE to this program has resulted in measurable monetary and operational benefits. We 1) summarize the DCSE to MBSE transition, 2) describe the accomplishments and observations to date, 3) define the metrics collected, and 4) quantify the achieved ROI. Background on the systems engineering and integration (SE&I) process and an apples-to-apples comparison of SE quality and efficiency are provided. The raw SE&I efficiencies of the DCSE and MBSE approaches are documented, along with conclusions showing that the MBSE approach delivers a positive ROI through higher quality SE products at significantly less cost-per-change, enables managing more baselines and SoS complexity using constant resources, and reduces the cost of the downstream integration effort.

“…Roadmaps connect an organizations’ vision, values, and objectives with concrete actions that can be taken to ensure their fulfillment (Geum and Park, 2012). According to Collins et al (2017), roadmaps have a positive influence on technology implementation, while Ghazisaeidi et al (2014) and Safdari et al (2015) believed them to be of critical importance. Thus, this study proposed the following hypothesis:…”

In the modern world, the amount of information stored in modern technology has been exponentially increasing. Access to vast amounts of information has changed how governments, institutions, organizations, and individuals conduct their business and record keeping. The increased use of cloud computing in conjunction with information and communication technologies (ICT), office automation, and digitalization has altered how electronic records are generated. Organizations should embrace this emerging environment to ensure competent operations and regulatory compliance well into the future. The absence of framework makes it difficult to implement the Electronic Records Management System (ERMS). Thus, this study proposed a framework for ERMS implementation and identified the most critical factors that are related to the ERMS characteristics and cloud characteristics. The ERMS implementation will improve Yemeni public sector educational institution competency and such implementation will be facilitated by the proposed framework. The study uses the Technology Acceptance Model 3 (TAM3) to implement a cloud Electronic Records Management System (ERMS). In addition to that, the study used a quantitative approach method and distributed questionnaires to 350 academicians and managers in the Yemeni public education sector. Variable relationships were identified using Partial Least Square-Structural Equation Modelling (PLS-SEM) through a second-order analysis method. All the identified factors were found to be essential and have a significant relationship with the behavioral intention to implement ERMS. The findings also revealed that ERMS plays a substantial and vital role in the competency of educational organizations. In other words, the study results demonstrated the importance of ERMS and Cloud dimension to ERMS implementation as well as the significant effect of ERMS implementation on public sector educational competency. These findings of the study have the potential to assist in shaping the direction of theory and empirical studies concerning the ERMS, particularly in its implementation to support the competency of educational institutions.
