Hi all,
I have a table that contains production and stops data of a machine:
Type_ap | DATE_TIME_START | DATE_TIME_END | TIME_ELAPSED | NET_TIME_ELAPSED |
Production | 06/07/2016 05:20 | 06/07/2016 10:57 | 5,6333333 | 5,633333334 |
Production | 06/07/2016 10:58 | 06/07/2016 12:58 | 2,0166667 | 2,016666667 |
Production | 06/07/2016 12:59 | 06/07/2016 13:39 | 0,6833333 | 0,683333333 |
Production | 06/07/2016 13:40 | 06/07/2016 17:00 | 3,35 | 3,35 |
Production | 06/07/2016 17:01 | 06/07/2016 21:59 | 4,9833333 | 2,983333334 |
Stop | 06/07/2016 17:01 | 06/07/2016 17:48 | 0,8 | |
Stop | 06/07/2016 18:00 | 06/07/2016 18:20 | 0,35 | |
Stop | 06/07/2016 20:00 | 06/07/2016 20:50 | 0,85 | |
Production | 06/07/2016 22:00 | 07/07/2016 05:19 | 7,3333333 | 6,61666666 |
Stop | 07/07/2016 01:00 | 07/07/2016 01:42 | 0,7166667 |
In Excel I am calculating using SUMIFS (example regarding first row)
=D2-SUMIFS($D$2:$D$11;$A$2:$A$11;"Stop";$B$2:$B$11;">="&B2;$C$2:$C$11;"<="&C2)
Which means that for each row I am subtracting STOP TIME_ELAPSED from PRODUCTION TIME_ELAPSED, but only if STOP START TIME is greater or equal than PRODUCTION START TIME and if STOP END TIME is lower or equal than PRODUCTION END TIME.
Stop time must be between production time to be subtracted and generated NET_TIME_ELAPSED.
Any suggestion on how to create NET_TIME_ELAPSED in Qlikview using Set Analysis?
Thanks
NET_TIME_ELAPSED was wrong. Instead of 4,9833333 should be 2,983333334 and instead of 7,3333333 should be 6,61666666
Production 06/07/2016 17:01 06/07/2016 21:59 4,9833333 4,983333334 Stop 06/07/2016 17:01 06/07/2016 17:48 0,8
How can one machine do both Production and Stop during the same time?
Hi ,
try this , But you have look in to your Date formats ..
SUM( {<Type_ap={"stop"},DATE_TIME_START={">=$(=max(DATE_TIME_START))"},
DATE_TIME_END={"<=$(=max(DATE_TIME_END))">} TIME_ELAPSED)
I agree with you.
But considering inputs are manuals, I will not change the logic of a whole factory if I can solve it in a simple way. Otherwise factory must hire more people just to be inputting every stop and restart.
That's fine, but I don't understand the logic. How is determined what should be subtracted from what? Unless you can give an exact algorithm for that I don't know how to create a solution.
I need to subtract all stopped time, that are inside a production interval.
In example, my production shift is from 9am to 5pm. This interval contains some stops that I also know begin and end. First stop from 10am to 11am due to machine maintenance. Then I have another stop from noon to 1pm for operator lunch. So my net production elapsed time is not 8 hours, but 6.
Did not worked. Field returned error.
My date and time formats:
SET DateFormat='DD/MM/YYYY';
SET TimestampFormat='DD/MM/YYYY hh:mm:ss[.fff]';
try this
SUM( {<Type_ap={"stop"},DATE_TIME_START={">=$(=date(max(DATE_TIME_START),'DD/MM/YYYY')"},
DATE_TIME_END={"<=$(=date(max(DATE_TIME_END),'DD/MM/YYYY')">} TIME_ELAPSED)
Perhaps something like this:
Data:
LOAD
DATE_TIME_START ,
DATE_TIME_END ,
TIME_ELAPSED
FROM
source_table
WHERE
Type_ap = 'Production'
;
JOIN (DATA)
LOAD
DATE_TIME_START as Stop_DATE_TIME_START,
DATE_TIME_END as Stop_DATE_TIME_END,
TIME_ELAPSED as Stop_TIME_ELAPSED
FROM
source_table
WHERE
Type_ap = 'Stop'
;
Temp1:
LOAD
DATE_TIME_START ,
DATE_TIME_END ,
TIME_ELAPSED - Stop_TIME_ELAPSED as NET_TIME_ELAPSED
RESIDENT
Data
WHERE
Stop_DATE_TIME_START >= DATE_TIME_START
AND Stop_DATE_TIME_END <= DATE_TIME_END
;
Temp2:
LOAD
DATE_TIME_START ,
DATE_TIME_END ,
TIME_ELAPSED
FROM
source_table
WHERE
Type_ap = 'Production'
;
JOIN (Temp2)
LOAD
DATE_TIME_START ,
DATE_TIME_END ,
TIME_ELAPSED ,
NET_TIME_ELAPSED
RESIDENT
Temp1
;
Result:
LOAD
DATE_TIME_START ,
DATE_TIME_END ,
TIME_ELAPSED ,
sum(NET_TIME_ELAPSED) as NET_TIME_ELAPSED
RESIDENT
Temp2
GROUP BY
DATE_TIME_START ,
DATE_TIME_END ,
TIME_ELAPSED
;
DROP TABLES Data, Temp1, Temp2;
Not worked.
My guess is that error is related to DATE_TIME_* fields are timestamp, and the result should by NET_TIME_ELAPSED for each production interval, and not for a day.
When we use DATE_TIME_START={">=$(=max(DATE_TIME_START))", considering we are only summing STOP, how will QV understands that (stop) DATE_TIME_START should be >= (production) DATE_TIME_START if both fields have the same name? Probably I will have to rename fields on loading.
We are getting closer.
