Generating Novel Options during Systems Architecting: Psychological Principles, Systems Thinking, and Computer-Based Aiding
Systems Architecting is a decision-intensive process that stands to benefit from access to historical architectural options and the ability to rapidly generate novel ones. Despite this recognition, option generation, and, more precisely, the process of ...
Leveraging Variability Modeling Techniques for Architecture Trade Studies and Analysis
Increasing complexity in modern systems, as well as cost and schedule constraints, require a new paradigm of Systems Engineering to fulfill stakeholder needs. Challenges facing efficient trade studies include poor tool interoperability, lack of ...
A Simulation-Based Approach in Support of Project Management Training for Systems Engineers
Project management is taught in most systems engineering graduate programs. Project management courses and training aids traditionally focus on aspects of project scope-for instance, scheduling and resource allocation methods-and tend to neglect product ...
Systems Integration: Key Perspectives, Experiences, and Challenges
As systems continue to grow in scale and complexity, systems integration SI has become a key concern. This is especially the case in defense and aerospace. SI involves interfacing and enabling the interactions of component elements to collectively ...
Experimental Research and Future Approach on Evaluating Service-Oriented Architecture SOA Challenges in a Hard Real-Time Combat System Environment
As the integration and interoperability demands among heterogeneous systems increase, Service-Oriented Architectures SOAs have provided a potential technical solution to integrate these complex systems within an enterprise framework. This paper presents ...
Functional and Spatial System Model for City Infrastructure Systems: A City.Net IES Case Study
City infrastructure systems have distinct functions but are not isolated from one another, with interactions existing between these systems. Modeling these systems requires a focus on the system functions and interdependencies. Most models focus on ...
System Security Requirements Analysis: A Smart Grid Case Study
One of the main concerns in development and operation of mission-critical systems is system security. It is of critical importance to properly specify and implement system security requirements. In this paper, we apply a system security requirements ...
Comparison of Risk Analysis Approaches and a Case Study of the Risk of Incorporating Solar Photovoltaic Systems into a Commercial Electric Power Grid
This paper compares two common risk-modeling approaches and then uses them to analyze the risk of incorporating solar photovoltaic PV systems into a commercial electric power grid. It uses procedures from both approaches such as Hierarchical Holographic ...
Systems Theory as the Foundation for Understanding Systems
As currently used, systems theory is lacking a universally agreed upon definition. The purpose of this paper is to offer a resolution by articulating a formal definition of systems theory. This definition is presented as a unified group of specific ...
