Thanks for all the ideas.. The easiest way is to do parallel routing. The
posting will be doing the actual reporting..

Eriq,

I guess I'm having trouble with the word simultaneous as it's used in your
scenario. Webster defines simultaneous as 'existing or occurring at the
same time, exactly coincident. Ex. The two events were simultaneously
scheduled to start at 10 AM.' This sounds more like parallel than what you
are describing below. What you describe is overlap or send ahead - that is
if I understand your example below correctly.

What I understand you want is:
Operation 1 - starts day 1, hour 1, minute 1 Operation 2 - starts day 1,
hour 1, minute 2 (or whatever time it takes to complete the first unit) The
way BPCS handles this is with negative move and/or queue. However, the
smallest increment of move and queue that can be entered is a single decimal
of days - which means 1/10 of a day.
I think another reply asked about what basis code you are using on the
routing. Using the 'P' basis code may be of some help. You say you can
produce 261 unit in a day. You could translate that into pieces per hour
and try negative .1 day of queue and see what happens.
As far as capacity, if you say you can product 32.62 pieces per hour using
basis code 'P' (this equates roughly to 261 pieces in an 8 hour day) and if
you're capacity is 8 hrs, then if you have an order for 270, BPCS should
schedule the completion the following day.

Eriq states:
Please see below for the scenario I am trying to reconcile:

I have 5 operations which are machine dependent. This will be a continuous
process that means after the first unit on the first operation, it will go
to the second machine/operation and the first machine will process the next
unit. This will be going up to the fifth operation.

If the 5 operation/machine can finish 261 units in a day, that means the
shop order will schedule it in a day. The problem with the -1 move days, it
does parallel scheduling for 5 machines/operation. It means that it will run
the operation at same time and not simultaneously. And if I have more than
the capacity per day of that 5 operation which is more than 261, for example
270 units. It will still schedule the shop order in a day since the
operations are running at same time and it does not compute for the
simultaneous operation time.
Does anyone have idea on defining the routing simultaneously?

The total hours required is correct. The costing will account for all
the time.

Are you trying to schedule start date / completion date?
There is a move time field. You can use < move > to overlap
operations. Problem this is a fixed number of time not PPH.

Does anybody knows how to route 5 operations/machines simultaneously?

If all 5 happen simultaneously like in a cell / continues flow.
You could create a work center that represents the cell (all 5 steps).
Then adjust the number of operators to calculate labor hours.

If all happen in a flow do you really want to report at each step?

Eriq,
I haven't had a chance to deeply look at your particular scenario in LX yet,
but there isn't anything in BPCS that keeps track of each individual Unit of
a shop order. You basically just report what has been completed.
So you can report on any of the operations some quantity completed. When
the total quantity for an operation has been completed you mark that
operation complete. The next operation is still open and the difference
between the Needed vs Finished is the outstanding - obviously. So it
would look something like this....

SO creation - No work completed yet.
OP1 - Req = 261 Fin = 0
OP2 - Req = 261 Fin = 0
OP3 - Req = 261 Fin = 0
OP4 - Req = 261 Fin = 0
OP5 - Req = 261 Fin = 0

First piece on OP1 completed.
OP1 - Req = 261 Fin = 1
OP2 - Req = 261 Fin = 0
OP3 - Req = 261 Fin = 0
OP4 - Req = 261 Fin = 0
OP5 - Req = 261 Fin = 0

Second piece on OP1 completed.
OP1 - Req = 261 Fin = 2
OP2 - Req = 261 Fin = 1
OP3 - Req = 261 Fin = 0
OP4 - Req = 261 Fin = 0
OP5 - Req = 261 Fin = 0

Third piece on OP1 completed.
OP1 - Req = 261 Fin = 3
OP2 - Req = 261 Fin = 2
OP3 - Req = 261 Fin = 1
OP4 - Req = 261 Fin = 0
OP5 - Req = 261 Fin = 0

Fourth piece on OP1 completed.
OP1 - Req = 261 Fin = 4
OP2 - Req = 261 Fin = 3
OP3 - Req = 261 Fin = 2
OP4 - Req = 261 Fin = 1
OP5 - Req = 261 Fin = 0

Fifth piece on OP1 completed.
OP1 - Req = 261 Fin = 5
OP2 - Req = 261 Fin = 4
OP3 - Req = 261 Fin = 3
OP4 - Req = 261 Fin = 2
OP5 - Req = 261 Fin = 1

There isn't anything to keep you from starting on the next operations just

because the first one hasn't been completed for the total quantity.

[BPCS-L] Routing Logic

Hi,

I am new in the manufacturing concept and we are trying to reconcile the
routing of our client.
Does anybody knows how to route 5 operations/machines simultaneously.

Example we have 261 units as orders and we will route it in 5
operations/machines. The problem is we can't route it simultaneously in
ERPLX where after the first operation for the first unit, it will go
directly to next operation. It should run one after the other. And the first
machine should get the next unit.

On the set up we have, the first operation finish first the 261 units before
it goes to the next.

Regards,
Eriq

Eriq,

Bryce is correct regarding the 'reporting of production'. However, your
question asks 'how to route 5 operations/machines simultaneously'. This
suggests you are trying to figure out a way to perform parallel scheduling
of the 5 operations. You do provide information in the 2nd paragraph
referencing first operation for the first unit, going directly to next
operation - which would contradict parallel scheduling and be more like
overlap scheduling, also referred to as send ahead. I have created a kind
of white paper on some findings regarding BPCS work center scheduling logic
that I'd be happy to forward directly to you as an attachment if requested.

The net is that normal BPCS scheduling logic for start and due date
calculations for use in capacity planning and work center scheduling uses
linear scheduling - meaning operation 1, then operation 2, then operation 3,
and so on. If you want operation 2 to start before operation 1 finishes
(overlap or send ahead) the use of some combination of negative queue and/or
move time allows this to be accomplished from a scheduling perspective.
Likewise, parallel scheduling (operation 1 and operation 2 start on the same
date and complete on the same date) can also be accomplished using negative
queue and/or move.

The calculation of start and end dates using any of the 3 methods (linear,
overlap, parallel) don't prevent you from reporting hours/quantities as they
are completed as Bryce indicates.

Hope this helps.
