Re: R: CAP100 (for Virgilio) -- BPCS-L

Virgilio,
 
Yes, your interpretation (below) regarding Input & Output Hours is absolutely 
correct. These statistics are tracked to ensure the hours are "flowing" through 
your workcenters as planned, and bottlenecks are managed.

Mike , 
So, if I have understood well, if it turns out that a wkc's actual output
hrs in a given period are much less than the actual input hrs in that same
period, that wkc may be a bottleneck unless some unexpected event has kept
it from working. The same holds true if the planned output hrs constantly
exceed planned input hrs. Is that correct?

Virgilio

Here is my understanding of Actual Input and Actual Output Hours for a 
workcenter:

The Actual Input hours "arrive" into a workcenter when the previous operation 
on a Shop Order is completed via nornal SFC or JIT reporting. If a workcenter 
is associated with the very first operation on the order, the Actual Input 
hours "arrive" the moment the Shop Order is created. See the brief example 
below:

Oper.# 10,   @ Workcenter# 100,   32 Hrs.    100 Pcs.
Oper.# 20,   @ Workcenter# 200,   60 Hrs.    100 Pcs.


*      
        Since Oper#10 is the first step on the Shop Order Routing, 32 Hours 
would arrive into Actual Input as soon as the Shop Order is created.
*      
        As production is reported against Oper.#10, those hours (at standard) 
become Actual Output from Workcenter # 100. Therefore, if 50 pcs were reported 
complete against Oper.# 10, then 16 hours would become credited as Actual 
Output. Even if the operator reported that it took 40 hours to complete those 
50 pcs, the workcenter still only gets credit for 16 Actual Ouput hours (the 
hrs. are pro-rated by actual quantity completed.)
*      
        As soon as the 50 Pcs. are reported compete at Oper.# 10, BPCS 
"assumes" they are now waiting at Oper.# 20. Therefore, the Actual Input Hours 
for Workcenter # 200 has increased by 30 Hours (half of the planned 60 hours).
*      
        Naturally, if the entire quantity is completed for Oper.# 10, the 
entire 32 Standard Hours become Actual Output for Workcenter# 100, and the 
entire 60 hours becomes Actual Input for Workcenter# 200. Everything is driven 
by the actual quantities reported.

Planned Input and Output is populated as a result of Planned Orders in MPS & 
MRP, plus hours on Shop Orders that haven't reached these Workcenters yet.

Virgillo, I hope this helps with your planning. Good Luck!

We still haven't been able to understand how Bcps calculates input and

subject: [BPCS-L] AVAILABLE CAPACITY

Available Capacity

The capacity hours available at this work center on this day. Available
Capacity of a work center is calculated as follows:

Available Capacity = Daily Capacity  x  Work center Average Efficiency  x
DLP
Daily Capacity =Machine Speed factor  x  Hrs./Day

Machine Speed factor = (Machine #1 Speed?W/C Std Speed) + (Machine #2
Speed ? W/C Std Speed) + (Machine #n Speed ? W/C Std Speed)

Hrs. per Day =# Shifts  x  Hrs. per Shift


Input is how many hours (load) you schedule a workcenter for on a daily
basis. (this value is determined by Routing)

Output is how many hrs worked.

Labor variance is determined by hrs worked vs standard
