[Lecture 3] Process flow measures Flashcards
1
Q
Flow time
A
The total time spent by a flow unit within process boundaries
2
Q
Flow rate
A
Number of flow units that flow through a specific point in the process per unit of time
3
Q
Inventory
A
total number of flow units present within process boundaries
4
Q
Stable process
A
avg inflow rate is the same as avg outflow rate –> all the flow units that go into the proess must come out at some point
- a process with unlimited ‘capacity’
5
Q
Throughput definition
A
the avg number of flow units that flow through the process per units of time
6
Q
Formula for Little’s Law
A
I = RT
Average inventory (I) = Throughput (R) x Avg flow time (T)
I : measured in units
T : hours
R : units/hr
7
Q
How to reduce flow time? (from a managerial pov)
A
Reduce inventory
