Question

Q. Under a mass production paradigm, setup time was viewed as:

-A value-add to the customer in the form of an additional quality check

-A necessary operation to ensure the complicated machinery was sufficiently calibrated

-A mechanism to reduce cycle stocks

-A fraction of the total time and hence was not deemed important

Q. The existence of setup time in a production process results in all of the following except:

-Increases raw material, WIP, and finished goods inventories

-Decreases scrap rates

-Increases the average and variance of flow times

-Impedes responsiveness to customer requirements

Answer 1

Here, correct answer is “A necessary operation to ensure the complicated machinery was sufficiently calibrated”

Explanation:

Under a mass production paradigm, we will spend time in set up as we want to calibrate the machinery in a way, so, we could ensure smoothness of operations. Hence, correct answer is “A necessary operation to ensure the complicated machinery was sufficiently calibrated”. Other options are not relevant, so other options are eliminated.

Here, correct answer is “Increases the average and variance of flow times”

Explanation:

We consider set up as to decrease scrape rates and to improve various inventories like raw material, WIP, and finished goods, using such set up time, it could also impede responsiveness to customer requirements. As it added time to cycle time of each part production, using set up time, we could also minimize the average and variance of flow times. Hence, correct answer is “Increases the average and variance of flow times” as this statement is wrong.
