|
|
upside down triangles |
waits, queues, storage (also known as a buffer) |
|
|
diamonds |
decisions point (ex. change given to a customer) |
|
|
process capacity= |
=minimum (capacity of resource n |
|
|
the throughput of a process is the minimum |
-supply -demand -capacity |
|
|
throughput |
the rate at which the system generates money through sales |
|
|
inventory |
all the money the system has invested in things which intends to sell |
|
|
operational expense |
all the money the system has to spend in order to turn inventory into throughput |
|
|
how do we make money? |
increase throughput while simultaneously decreasing inventory and operational expenses
throughput is KEY. want to make changes that increase throughput |
|
|
bottleneck |
anything that limits throughput |
|
|
2 things that limit throughput |
system capacity market capacity |
|
|
capacity of the system |
the number of units the system is capable of producing in a given unit of time |
|
|
operation time= |
set up time+run time |
|
|
flow time (throughput time)= |
average time for a unit to move through the system (including waiting time) |
|
|
cycle time |
average time between completion of successful units in a process |
|
|
relative measures (3) |
utilization=time activated/time available productivity=output/input efficiency=actual output/standard output |
|
|
little's law |
the flow of items through a production process. inventory=throughput rates x flow time
|
|
|
what is a batch |
number of units processed at a resource before an additional setup is needed
single production line can be used to produce
ex. bakery, sports shoes, paint, ink |
