Question 29

Little's law states that supply chain processes can be regarded as unrelated and thus treated and analyzed separately.

Question 30

In balancing an assembly line,workstation cycle time has to be less than the time between successive units coming off the end of the line.

Question 31

C)9.6
D)480
E)Cannot be determined from the information above

Question 37

The efficiency of an assembly-line is found by a ratio of the sum of all task times divided by the cycle time.

Question 38

high-level map or diagram of a supply chain process can be useful to understand how material flows and where inventory is held.

Question 39

Little's law can be thought of as a relationship between units and time.
