#### As the number of components rises, system dependability for series-connected components deteriorates.

Correct! Wrong!

As the number of components rises, so does the reliability of the system for those kept in series. The system reliability in this instance is always lower than the lowest reliability value of any component.

#### Which of the following expressions, among Ohno's seven categories of waste, refers to the waiting period between two processes ending?

Correct! Wrong!

Waiting is the act of waiting for one process to start while another completes. The flow of operations must be constant and seamless.

#### A system consists of four interconnected components, two of which are reliable at 0.9 and the other two at 0.8 at the end of a year. At the end of a year, how reliable is the system?

Correct! Wrong!

After a year, the system's reliability is determined by R(s)=R1*R2*R3*R4. So, R(s)=0.9*0.9*0.8*0.8=0.5184.

#### As the number of components rises, system reliability for parallel-running components decreases.

Correct! Wrong!

As the number of components rises, so does the reliability of the system for components maintained in parallel. The system dependability in this instance is consistently higher than the highest reliability rating of any component.

#### The whole system's dependability is referred to as .

Correct! Wrong!

System reliability is the dependability of the overall system. A system is a grouping of objects like components, units, blocks, subsystems, etc.

#### The entire system will malfunction in a parallel configuration with five components if .

Correct! Wrong!

If any one of the five components in a parallel setup fails, the system as a whole will also fail. In the event that any one of the parallel components fails, the system will still function satisfactorily.

#### What does the "bathtub curve" graph indicate?

Correct! Wrong!

Failure rate v/s time is shown by the "bathtub curve." The debugging phase, chance-failure phase, and wear-out phase are its three separate phases.

#### When a predetermined number of failures occur in the sample, the life-test sample plans are .

Correct! Wrong!

The life-test sample plans are failure-terminated when the sample experiences a certain number of failures. Sequential testing and time-terminated tests make up the remaining categories.

#### Which of the following does not fall within Ohno's seven categories for waste?

Correct! Wrong!

The seven categories of wastes established by Ohno include inappropriate processing, surplus inventory, and wasteful motion. The seven different categories of trash established by Ohno include defects as well.

#### The entire system will malfunction in a series configuration with five components if .

Correct! Wrong!

If any one of the five components in a series setup fails, the entire system will malfunction. Only if every component operates flawlessly will the system as a whole function satisfactorily.

#### Which of the following is a system of visual and/or auditory communication that signals when assistance or attention is required in a process?

Correct! Wrong!

Andon is a system of visual and/or auditory communication that signals when assistance or attention is required in an activity. It might be a rope, a lamp, or a flag.

#### Testing for safety and inspection are two instances of Muda.

Correct! Wrong!

Muda Type 1 includes, for instance, inspection and safety testing. Despite having little value to add to the finished product, they are necessary for the client.

#### Which of the following expressions, among Ohno's seven categories of waste, views the transfer of goods between manufacturing processes as a costly, non-value-adding job that may also harm the product?

Correct! Wrong!

Transport refers to the expensive, no-value-added activity of moving a product between production processes. It can also result in product damage. It should be kept as far away from as feasible.

#### The Toyota Production System (TPS) was founded by who?

Correct! Wrong!

Ohno is credited as founding the Toyota Production System. In North America, the Toyota Production System idea is frequently referred to as Lean Manufacturing.

#### What is the individual dependability of five robots in a production line if the system reliability is 0.95?

Correct! Wrong!

Five robots in a production line have a 0.95 system dependability rating. R(s)=R1*R2*R3*R4*R5 determines the system's dependability. R(x)=0.9897 since R(x)5=0.95 or 0.95.

#### Five robots work on a production line on a daily basis. What is the overall system reliability if each robot has a dependability of 0.95?

Correct! Wrong!

Given by R(s)=R1*R2*R3*R4*R5, the system's dependability can be calculated. R(s) = 0.95 * 0.95 * 0.95 * 0.95, or 0.7737.
