Q

Flow-blocking delay vs lack-of-work

Definitely on the exam

A

delays occur when a work center completes a unit but cannot release it because the in-process storage at the next stage is full

delays occur whenever one stage completes work and no units from the previous stage are awaiting processing.

Q

The purpose of the assembly line balancing:

A

the purpose is have keep workers to have the same amount of work so there isn’t any delays

Q

We need to know three types of information to balance an assembly line:

A
  1. the set of tasks to be performed and the time required to perform each task
  2. the precedence relations among the tasks
  3. the desired output rate or demand forecast for the assembly line

16
Q

Throughput is measured in:

A

units

17
Q

________ throughput increase cycle time

A

Decrease

18
Q

_______ throughput decrease cycle time

A

Increase

19
Q

Decrease throughput ______ cycle time

A

increase

20
Q

Increase throughput ______ cycle time

A

decrease

21
Q

The longest cycle time is what?

A

the sum of the task times (past times)

22
Q

The longest cycle time will give you what?

A

you the lowest throughput (output)

23
Q

The shortest cycle time is what?

A

the longest past time that will give you the highest throughput

24
Q

Flow Time

A

is the average time to complete one cycle of a process (time/unit).

25
Q

Cycle Time

A

is the interval between two successive outputs (time/unit).

26
Q

How is throughput and cycle time related?

A

It is inversely related

27
Q

Can your assembly time be 100% balanced when you have 1.6 work stations?

A

No, it cannot be as it has to be an exact integer (1, 2, etc). It can’t have a fraction. If it has a fraction there will be idle time.

28
Q

What is the inefficiency time?

A

the total idle time

29
Q

Why do you want a longest task time first?

test question

A

because shortest task time is easier to fit in a line

30
Q

Why do you want a shortest task time first?

test question

A

so that the idle time is minimized

31
Q

Make sure you go over the math questions and practice the problems on the slides as it’s going to be on the test
(test)
