Study Notes
Module 1: Introduction
- An open system allows information, energy, and matter to cross its boundaries and interacts with its environment.
- A system is an assemblage or combination of functionally related elements or parts forming a unitary whole.
- Examples of systems include water systems and transportation systems.
System Elements
- Components: parts of a system.
- Attributes: properties of components and the system as a whole.
- Relationships: connections between components that result from engineering their attributes.
Physical and Conceptual Systems
- Physical systems manifest themselves in physical form and consume physical space.
- Conceptual systems consist of symbols, plans, ideas, and hypotheses that represent the attributes of components.
System of Systems (SOS)
- SOS is a group of related systems that are normally analyzed individually.
- Examples of SOS include a system of transportation systems or a system of water systems.
Dynamic System
- A dynamic system exhibits behaviors due to the combination of structural components with operating and/or flow components.
- Dynamic systems have functional purposes, achieve stated operational objectives, and have design momentum.
Module 4: Systems Engineering Process
- Concept development: an early phase in product development that lays out the general concept of a product.
- Problem definition and need identification: the first step in the systems engineering process.
System Design and Feasibility Analysis
- Advanced system planning and architecture development: bringing a new or improved capability to a system.
- System design involves developing system-level architecture and technical requirements.
Module 6: Detail Design and Development
- Typical engineering drawing categories include system specifications, development specifications, and product specifications.
- The integration of system elements involves allocating design requirements to the subsystem level.
- Basic design sequence with feedback involves design data review, parameter measurement, and evaluation.
Module 7: System Test, Evaluation, and Validation
- System requirements and evaluation relationships involve testing and evaluating system performance.
- System test, evaluation, and validation checklist includes system requirements, evaluation procedures, and test results.
- System evaluation and corrective action loop involves identifying and correcting system deficiencies.
Learn about the basics of systems, including open systems, and how they interact with their environment to achieve a steady state.
