This document discusses software modeling from a system perspective. It defines key concepts such as a system, system element, and block. A system is composed of interacting elements organized to achieve a purpose. A system element may itself be a system or an atomic entity. The document recommends using unified modeling concepts like "block" to represent a system, subsystem, component or other entity. It presents different modeling views including context, services, structure and behavior, and discusses modeling techniques like use case diagrams, activity diagrams and more.

This document discusses the challenges of software engineering education and proposes ways to improve it. It suggests extending the sustainability range from employment to career development; extending practice from programming and design to business and management; extending the software lifecycle from design-code-test to deploy-validate-maintain-reuse; extending scope from software to entire systems; and extending the profession from software engineering to software-intensive systems engineering. It emphasizes incorporating more real-world experience, career development, business skills, and systems thinking into software engineering education to better prepare students and address industry needs.
This document discusses how software affects system development from the perspective of software-intensive systems engineering. It begins by explaining that most systems today have software as an essential component, as software contributes to their design, construction, operation, and evolution. It then provides examples of how software influences system operation through its unique mathematical properties and vulnerability, as well as impacting system design through different development lifecycles and challenges of bring your own device integration. The document concludes by arguing that systems engineering and software engineering must work together through common standards, modeling languages, lifecycle models, and education.

This document provides an introduction to embedded systems architecture. Chapter 1 defines an embedded system and introduces a systems engineering design process. It describes embedded systems as computer systems with dedicated functions that are often subject to strict reliability requirements. The chapter then discusses the importance of defining an embedded system's architecture and introduces a layered model with hardware, system software, and application layers. It emphasizes that understanding an architecture allows designers to address challenges like cost, integrity, and functionality.
System engineering involves determining operational requirements and modeling relationships between elements like hardware, software, and people to accomplish goals. It can focus on business processes or product development. The engineering process follows a hierarchy from overall objectives to domain specifications to element implementations. It is iterative to adapt to changing needs. Business process engineering derives data, application, and technology architectures, while product engineering defines architectures and infrastructure for software, hardware, data, and people components.

The document discusses prototypes and the spiral model of software development. It defines a prototype as a working model built to test design aspects. The spiral model combines prototyping and the waterfall model, with software development occurring in iterative loops or spirals of planning, risk analysis, engineering, and evaluation. Each spiral builds upon the previous one with increasing requirements, reduced risks, and additional features developed. The spiral model is useful for large, risky projects where requirements are unclear.

Availability Assessment of Software Systems Architecture Using Formal ModelsEditor IJCATR
There has been a significant effort to analyze, design and implement the information systems to process the information and data, and solve various problems. On the one hand, complexity of the contemporary systems, and eye-catching increase in the variety and volume of information has led to great number of the components and elements, and more complex structure and organization of the information systems. On the other hand, it is necessary to develop the systems which meet all of the stakeholders' functional and non-functional requirements. Considering the fact that evaluation and assessment of the aforementioned requirements - prior to the design and implementation phases - will consume less time and reduce costs, the best time to measure the evaluable behavior of the system is when its software architecture is provided. One of the ways to evaluate the architecture of software is creation of an executable model of architecture.
The present research used availability assessment and took repair, maintenance and accident time parameters into consideration. Failures of software and hardware components have been considered in the architecture of software systems. To describe the architecture easily, the authors used Unified Modeling Language (UML). However, due to the informality of UML, they utilized Colored Petri Nets (CPN) for assessment too. Eventually, the researchers evaluated a CPN-based executable model of architecture through CPN-Tools.

Track 3 Session 1 Moderator: Matthew Hause
Capturing stakeholder needs with MBSE and using the System of Systems VEE™ model for evaluating control, communications, and threat and vulnerability assessment.
Mark Walker- Paper 1: Process and Methods: A fundamental premise of this presentation is that capturing stakeholder needs and the initial development of Systems Engineering documents and architecture models, with top level capability needs/requirements, in a well written rational Concept Document (OCD). This needs to be developed during the first stages of a development which is absolutely critical for the entire life cycle of the system development. With this information in the OCD, written substantially in the stakeholder’s operational terminology, and with Systems Modeling Language (SysMLTM) architecture views, this set of integrated products provide the foundation for all future stages of a development and the system’s operational life. The primary emphasis is the critical importance of the “System” Use Case Diagrams (SysUCD), their associated Scenarios and Sequence Diagrams and how essential it is to develop these with the operational customer in this first stage. This is accomplished by applying the Stakeholder Needs Analysis process using the recommended Object Oriented Systems Engineering Method (OOSEM) and translating the information into well-defined stakeholder and systems engineering products and architecture views/models
Software testing and introduction to qualityDhanashriAmbre
The document provides an overview of software testing and quality assurance. It defines software testing as a process to investigate quality and find defects between expected and actual results. Testing is necessary to ensure software is defect-free per customer specifications and increases reliability. The document then discusses types of errors like ambiguous specifications, misunderstood specifications, and logic/coding errors. It outlines the software development life cycle including phases like planning, analysis, design, coding, testing, implementation, and maintenance. Each phase is described in 1-2 sentences.
The document proposes modifications to the Essence kernel to better represent systems engineering concepts. It suggests splitting the current "System" alpha into separate "System Definition" and "System Realization" alphas to distinguish between defining system requirements, architecture, and design, and realizing the physical system. "System Definition" would have requirements, architecture, and design as sub-alphas. It also discusses representing systems engineering frameworks and modeling languages as part of the "Way of Working" alpha. The proposal aims to capture systems engineering concepts like the V-model life cycle and better align the Essence kernel with standards like ISO 15926 and ISO 42010.

The objective of this paper is to provide an insight preview into various
agent oriented methodologies by using an enhanced comparison
framework based on criteria like process related criteria, steps and
techniques related criteria, steps and usability criteria, model related or
“concepts” related criteria, comparison regarding model related criteria
and comparison regarding supportive related criteria. The result also
constitutes inputs collected from the users of the agent oriented
methodologies through a questionnaire based survey.
A Review of Feature Model Position in the Software Product Line and Its Extra...CSCJournals
The software has become a modern asset and competitive product. The product line that has long been used in manufacturing and construction industries nowadays has attracted a lot of attention in software industry. Most importance of product line engineering approach is in cost and time issues involved in marketing. Feature model is one of the most important methods of documenting variability in product line that shows product features and their dependencies. Because of the magnitude and complexity of the product line, build and maintain feature models are complex and time-consuming work. In this article feature model importance and position in product line is discussed and feature model extraction methods are reviewed and compared.
The document discusses the Unified Modeling Language (UML) and use case modeling. UML was developed to provide modeling languages for software design including use case diagrams, class diagrams, and other diagrams. It describes the typical phases of system development like requirements analysis, design, implementation, and testing. It then focuses on use case modeling, explaining what a use case is, how to identify actors and use cases, and how to describe use cases. Examples of use case diagrams are provided for different systems like an ATM machine and counseling.
This document provides an introduction to software engineering and object-oriented concepts. It defines key terms like program, documentation, software characteristics. It describes various software engineering methodologies like Coad and Yourdon, Booch, Rumbaugh, and Jacobson. It also discusses object-oriented modeling, the Unified Modeling Language (UML), and compares traditional vs. object-oriented approaches.
