Questions and Answers

What is the primary purpose of Manufacturability/Producibility Analysis?

  • To overlook the capability to manufacture or produce a system
  • To increase the complexity of the production process
  • To enable production in a responsible and cost-effective manner (correct)
  • To encourage unnecessary costs and project delays

    • Why is the capability to manufacture or produce a system considered essential?

  • To limit the type and number of systems being produced
  • To increase project delays and cost overruns
  • To prevent unnecessary costs and rework (correct)
  • To ensure that production takes place on-site

    • In what way do producibility considerations differ depending on the type and number of systems being produced?

  • They don't differ at all, regardless of the type and number of systems being produced
  • The considerations are only relevant for high production runs, such as mobile phones
  • The considerations vary based on the type and number of systems being produced (correct)
  • The considerations only depend on whether the production takes place in a factory or on-site

    Study Notes

    • A maintainability engineering plan is used to capture activities related to maintainability, including quantitative modeling and simulation, system maintenance concept, level of repair analysis, diagnostic capabilities, and preventive maintenance.
    • Maintainability engineering is closely related to logistics engineering.
    • testability is an important aspect of maintainability, which includes built-in test capability, diagnostic test equipment, and support software.
    • Service providers may use Over-the-Air (OTA) technology to remotely provide maintenance.
    • Maintainability requirements should be derived from system availability requirements.
    • Mean Time to Repair (MTTR) is a commonly used maintainability metric to measure the elapsed time to perform maintenance activities.
    • MTTR refers to the mean time of the underlying probability distribution and maintenance times are often lognormally distributed.
    • Reliability engineering, safety engineering, logistics engineering, affordability, resilience engineering, and reusability of products in a product line are related engineering disciplines to maintainability.
    • The life cycle cost of a system is highly dependent on reliability and maintainability.
    • Resilience engineering is an approach to provide required capability when facing adversity and it applies to cyber-physical, organizational, and conceptual systems.
    • The objectives of resilience are avoiding, withstanding, and recovering from adversity.
    • Resilience in engineering systems is the ability to provide required capability when facing adversity.
    • Identifying the capabilities required of the system, adverse conditions under which it is required to deliver those capabilities, and the architecture and design that will ensure the system can provide the required capabilities is part of resilience engineering.
    • Providing the required capability, not necessarily maintaining the architecture or composition of the system, is the goal of resilience.
    • System continuity and adaptability are approaches to achieving resilience.
    • Resilience engineering applies to all sources and types of adversity, including environmental and human sources, and system failure.
