Speed up the assembly line transfer mechanism

If the sum of the task times required to produce a product is 45 minutes and the cycle time for the same product is 10 minutes, the theoretical minimum number of the workstations is 5 using the assembly-line balancing procedure.

True

Which of the basic types of production layout formats is one which similar equipment or functions are grouped together?

Workcenter layout

Using the assembly-line balancing procedure, which of the following is the required cycle time if the production time in minutes per day is 1440 and the required output per day in units is 2000?

0.72

Using the assembly-line balancing procedure, which is the theoretical minimum number of workstations if the task times for the six tasks the make up the jobs are 4, 6, 7, 2, 6, and 5 minutes, and the cycle time is 10 minutes?

3

A job shop makes many different products in batches, each batch or job requiring the same set or sequence of processing steps.

False

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.

False

The percentage of the idle time in an assembly line is called cycle time.

False

You have just determined the actual number of workstations that will be used on an assembly line to be 8 using the assembly-line balancing procedure. The cycle time of the line is 10 minutes and the sum of all the tasks required on the line is 60 minutes. Which is the correct value for the resulting line's efficiency?

0.750

You have just determined the actual number of workstations that will be used on an assembly line to be 6 using the assembly-line balancing procedure. The cycle time of the line is 5 minutes and the sum of all the tasks required on the line is 25 minutes. Which is the correct value of the resulting line's efficiency?

0.833
