Systems Engineering

• Include those that came into being through natural processes

  Natural System
• A phase that may involve both the customer and the producer


  Acquisition Phase
• Give at least 2 Effectiveness Factor


  1. cost or system effectiveness
  2. operational availability, readiness rate, dependability
  3. logistics support effectiveness
  4. mean time between maintenance (MTBM)
  5. failure rate
  6. maintenance downtime (MDT)
  7. facility utilization
  8. operator skill levels
  9. task accomplishment requirements
  10. personnel efficiency
• The systems engineering process generally commences with the identification of a ___ or ___ for something based on some ___ deficiency.


  "want"" , ""desire"" , ""real"""
• it is the definition of the operating characteristics or functions of the system such as size, weight, range, accuracy, bits, capacity, transportation, receive, etc.

  performance and physical parameters
• Give at least one Systems Engineering Process Model

  Waterfall Process Model

  Spiral Process Model

  VEE Process Model
• These are considered as the parts of a system


  Components
• First and most important phase of the system design and development process.

  Conceptual Design Phase
• These are the properties (characteristics, configuration, qualities and etc) of the components and of the system as a whole

  Attributes
• is that characteristic of design and installation that reflects the ease, accuracy, safety, and economy of performing maintenance actions

  Maintainability
• give me at least one in the hierarchy of sets of elements

  subsystems

  components

  subcomponents

  parts
• It is also known as static parts

  Structural Components
• A structured process or mechanism for determining customer requirements and translating them into relevant technical requirements that each functional area and organization level can understand and act upon.

  Quality Function Deployment(QFD)
• Materials, energy, and/or information that pass from the system to the environment.

  Outputs
• It is an iterative process of breaking requirements down from the system level to the subsystem.

  Functional Analysis
• Is the categorization of systems, such as the Solar System, State University System, and an Engineered Swimming Pool Recreation System, accurately aligned with the classifications of Natural System, Human-Made System, and Human-Modified System, respectively is correct?

  Yes, Correct
• this is the lower system, if two hierarchical levels are involved in a given system

  subsystem
• Translating the preliminary design to tangible components


  Detail Design and Development Phase
• The application of _ and _ tools enables the projection of many different design alternatives throughout the life cycle


  Computer Aided engineering (CAE) and Computer aided design (CAD)
• There are three types of system prototype development models, give atleast 1 of the model.


  - engineering models

  - service test models

  - prototype model
• It should be presented in specific qualitative and quantitative terms and in enough detail to justify progressing to the next step. It is essential that the process begin by defining a real problem and its importance


  Statement of the problem
• __ are those in which human beings have intervened through components, attributes, and relationships.

  Human-made system
• the degree to which a system's design or or code is difficult to understand because of numerous components or relationships among components

  COMPLEXITY
• It extends the translation of system level requirement into design requirements for the subsystem level. Also known as advance development.


  Preliminary Design Phase
• It consists of all components, attributes, and relationships needed to accomplish one or more objectives.

  Total System
• Risk driven approach for the development of products or system

  Spiral Process Model
• Model that is characterized as an extension of the waterfall model, begins with user needs on the upper left and concludes with a user-validated system on the upper right?

  "VEE"" Process Model"
• identification of the quantity of equipment, software, personnel, facilities, and so on, and the expected geographical location to include transportation and mobility requirements.

  Operational deployment or distribution
• Should be performed with the objective of translating a broadly defined want into a more specific system-level requirement.

  Need Analysis
• (True or False) The Waterfall process model was introduced by Royce in the year 1970 initially for software development.

  TRUE
• It is a risk driven approach for the development of products or system.

  Spiral Process Model
• In what year was the water process model introduced?

  1970
• Translate Customer Requirements into technical Requirements

  Product Planning
• Also know ln as advance development

  Preliminary Design Phase
• This system usually exhibit the characteristics of equilibrium resulting from internal rigidity that maintains the system in spite of influences from the environment.

  Closed Systems
• It exhibits behaviors because it combines structural components with operative and/or flow components

  Dynamic Systems
• The one whose states do not change because it has structural components but no operating or flow components as exemplified by a bridge


  Static Systems
• this exhibit the characteristics or steady state, where a dynamic interaction of system elements adjusts to changes in the environment

  Open Systems
• What is the Formula of MTBR, MTTF, and Failure Rate

  FR (%)= no. of failure/no. of operating time

  FR(n)=no. of failures/ ((total units tested*expected operating time)-(sum of non-operating time of failed units))

  MTTF or MTBF = no. of operating time/no. of failures
