Efficiency change in cycletime
Hi Nina,
In ED, one way to model variation of cycletime depending on #tasks performed is as follows:
1. Define a global variable (called "v_Efficiency", for example)
2. Each time a part enters the server, check to see if this variable should be updated. This decision would depend on your threshold for # tasks in which the efficiency is improved. An example of this is:
IF( INPUT(C) < 100, {If the operator has processed less than 100 parts}
v_EFFICIENCY := 0.80,
IF( INPUT(C) >= 100, {If the operator has processed 100 parts or more}
v_EFFICIENCY := 0.95,
IF( INPUT(C) >= 200, {If the operator has processed 200 parts or more}
v_EFFICIENCY := 1.00
)
)
)
3. In the cycletime field of that server, assuming the fastest time is 30 seconds, you would type in:
30/v_EFFICIENCY
I would assume a similar approach will also work in Arena.
Good luck!
Eric
