Q

What is logistics engineering?

A

Logistics engineering (Blanchard and Fabrycky, 2011), which may also be referred to as product support engineering, is the engineering discipline concerned with the identification, acquisition, procurement, and provisioning of all support resources required to sustain operation and maintenance of a system.

Q

What is value engineering?

A

VE uses a systematic process (e.g., a formal job plan), VE-certified facilitators/ team leads, and a multidisciplinary team approach to identify and evaluate solutions to complex problems in the life cycle of a project, process, or system. The objective is to achieve the essential functions at the lowest LCC consistent with required performance, reliability, availability, quality, and safety. VE is not a cost reduction activity but a function-oriented method to improve the value of a product. There is no limit to the field in which VE may be applied.

Q

What is LCC analysis?

A
  • Refers to the total cost incurred by a system, or product, throughout its life
  • “Total” cost varies by circumstances, the stakeholders’ points of view, and the product
  • Similar to Total Cost of Ownership (TCO) or Total Ownership Cost (TOC), but many times, these measures only include costs once the systems is purchased or acquired.
  • Prepare as accurate cost estimates as possible and assign risk as required.
  • LCC analysis can be used in affordability and system cost-effectiveness assessments.

Q

What is Reliability Engineering?

A

–The specialized engineering discipline that addresses the reliability of a system during its total life cycle.
–Used as collective term for the engineering discipline concerned with the RAM of a system

19
Q

What are the objectives of Reliability Engineering?

A

–To apply engineering knowledge and specialist techniques to prevent or to reduce the likelihood or frequency of failures
–To identify and correct the causes of failures that do occur, despite the efforts to prevent them
–To determine ways of coping with failures that do occur, if their causes have not been corrected
–To apply methods for estimating the likely reliability of new designs and for analyzing reliability data

20
Q

What does the Reliability Program Plan do?

A

Formally integrates Reliability Engineering with other SE technical processes

A
  • Engineering Analyses and Tests
  • Failure Analyses
22
Q

A

Defined as probability that a system, when used under stated conditions, will operate satisfactorily at any point in time as required

23
Q

What are the 3 types of availability?

A
  • Inherent - considers system only
  • Achieved - similar to inherent availability, except that preventive (i.e., scheduled) maintenance is included.
  • Operational - assumes an actual operational environment and therefore includes logistics delay time and administrative delay time
24

27
Q

What is the system safety order of precedence is used to define the order followed for implementing system safety requirements to reduce the mishap risk.

A
  1. Eliminate hazards through design selection.
  2. Reduce risk through design alteration.
  3. Incorporate safety devices.
  4. Provide warning devices.
  5. Develop procedures and training.
28
Q

How are system safety requirements V&V’d?

A

–Provide input to all tests, demonstrations, models, and inspections to verify compliance of the system with the identified system safety requirements
–Witness verification/validation activities for those hazards that were categorized as catastrophic and critical
–Review results from all test activities performed to validate/verify system safety requirements
–Capture test results and the test and evaluation reports in the Hazard Tracking System (HTS).

29
Q

What is done in assessing system safety risk?

A

–Identifies all safety features of the hardware, software, and system design.
–Identifies procedural, hardware, and software related hazards that may be present in the system at each milestone, test, or operation activity
–Identifies specific procedural controls and precautions for those hazards still present in the system.
–Identifies and documents hazardous materials used in the design, operation, or maintenance of the system as well as those that will be generated by the system
–Develop and document assessment as to why non- or less - hazardous materials could not be used

30
Q

What’s diff. between resilience engineering and system security engineering?

A

Just my opinion, but system security engineering seems more about preventing the threat from happening, whilst resilience engineering is assuming the threat has happened and limiting the damage thence.

31
Q

What is relationship between system engineer and system security engineer?

A

System security engineer is specialized in stuff like hardware assurance, anti-tamper, info assurance, supply chain risk management, etc. The systems engineer leverages these skills to obtain security recommendations, and jointly works with the SSE to develop a number of security plans (standard plans you’d expect but also deployment plan and disaster recovery/continuity plan).

32
Q

What are system security considerations for ACQ and SUP?

A
  • Enabling systems, supply chain, and all aspects of assembling a solution must be protected
  • Request for Proposal: include System Security analysis, evaluation, protection implementation, and updates
  • Vulnerability assessments must be made and updated throughout the life cycle.
  • COTS products
    • May have limited assurance that malicious insertion has not occurred
    • Used outside the SOI, may allow vulnerability discovery that could be exploited
    • Select only system elements that have secure supply chains
33
Q

What does training needs analysis address?

A

–Initial and follow-on training necessary to execute required tasks associated with system use and maintenance
–Understand the concept documents and the requirements for the SOI
–Identify specific list of functions or tasks from these sources and represent them as learning objectives for operators, maintainers, administrators, and other system users.
–Learning objectives then determine the design and development of the training modules and their means of delivery.

34
Q

What is the classroom environment being replaced with?

A

–Simulators,
–Computer-based training,
–Internet-based distance delivery,
–In-systems electronic support

35
Q

What is the primary objective of HSI?

A

Ensure that human capabilities and limitations are treated as critical system elements

36
Q

What are 2 key methods of HSI?

A
  • Analyses (especially requirements analysis)
  • Trade studies (include human related issues)
37

What is value in Value Engineering?

A

•Fair return or the equivalent in goods, services, or money for something exchanged
•Based on “what you get” relative to “what it cost.”
•Represented by the relationship:
Value = function/cost

A
  • The Basic Function is typically the deliverable or end state of the effort.
  • The Higher Order Function is the ultimate goal and is “why” the Basic Function is performed.
43
