False

Smart phones, automobiles, and laptops are all examples of systems were reliability sequential qualification testing can be used.

True

Reliability must be a technical performance measure and allocated to lower level requirements.

True

Probability refers to the interfaces that are measured to assess operational performance of an event.

False

Which are examples of stress-strength analysis?

  Transportation vibration analysis

  Packaging moisture analysis

  High-impact drop analysis

Which of the following determines all opportunities or chances where a failure can occur?

FMECA

Maintenance and support analysis utilize results from:

Reliability predictions

Under _________, the overall system reliability is shown to depend on the reliability of its lower-levels or subsystems.

 Component selection and application

Chapter 13+14

Under the _______ method, assemblies requiring maintenance are either maintained or disposed of.

Reliability centered maintenance

___________________ is defined as the “ability of a system to be maintained”.

Maintainability

A probability measure of Maintainability can be that maintenance is not needed in a system being operated properly more than a set amount of times in a defined time period.

True

Corrective maintenance is the type of maintenance that is scheduled in order to keep a system performing at defined performance levels.

False

____________________ takes place when changes are made to respond to changing requirements.

Adaptive maintenance

_____________ is the ability to perform the job intended and meet the operational demand.

System effectiveness

______________ involves decision-making where one either repairs or removes the item requiring maintenance.

Level-of-repair analysis

The Maintainability Demonstration takes place in the later parts of detail design and development in an environment very similar to the true real environment.

True

Maintenance task analysis (MTA) is used in production manufacturing to enhance productivity and lower costs.

False

Maintainability efforts begin in the conceptual phase.

True

What is the order in which human factors are broken down?

Task elements make up subtasks which make up tasks which make up duties which make up job operations.

________________ deal with dimensions of the human body

Anthropometric Factors

Which of the following can cause stressful environments?

Physiological Factors

The mental wellbeing of personnel, including how we process data, is covered under:

Psychological Factors

Which of the following are types of efficiency measures for operation and maintenance in human factors engineering? Select all that apply.

How many employees a system uses

The cost of on-the-job education

How long it takes to complete job functions

Humans can commit errors by either not doing a required duty or by doing a subtask incorrectly

True

Operator task analysis is an approach to study human factors which evaluates the flow of information flow from the beginning to the end.

False

Design for usability refers to non-human factors in systems such as hardware and software.

False

Chapter 15

Like other system design activities, logistics activities require early and continuous focus during the systems design life cycle.

True

Past efforts in logistics and supportability were involved with the management of material goods but were much more concerned with electronic data and information than in current efforts. 

False

___________ refers to managing the activities that make goods, information, funds and services available between all the entities involved from initial procurement to operational use.

Supply Chain Management

_________________ uses techniques and results from other analysis tools to resolve issues with the goal of defining required logistics and maintenance support resources.

Supportability Analysis

____________can be defined as the activities of planning, implementation and control of goods, services, and information between starting and consumption points in customer needs.

Logistics

Which are examples of business logistics activities? Select all that apply.

Moving goods from a supplier to a distributor

Defining how long produced parts will be in inventory before being delivered A sub-supplier’s packaging of products that will be delivered to major suppliers

The people, resources, documentation and locations involved with providing personnel with required know-how and abilities is known as:

Training and training support

A building used to store products is an example of:

Maintenance support facilities and utilities

Chapter 16

___________________ is a concept that deals with reducing the effects that systems and their processes have on the environment.

Environmentally Conscious Design and Manufacturing

Processing a metal to keep it from corroding is an example of __________.

Properties modification

______________ includes activities like using less parts during manufacturing and taking apart or disassembling a system to dispose and/or recycle its sub-components.
