# 1. Calculation of Delay in a work using shif timing

Oct 16 2010 4:59 AM
Hi All,

I want to calculate delay time for any work/process. I have shifts timing table just like office timing and it may be 1st, 2nd, or 3rd shift in a day. In between the timing few minute breaks are there for lunch or tea break etc.

One work/Process may be finished within 1st shift or it may go to 2nd, 3rd shift also or work may go to next day any shift also. And I have  a standard time for the work/process to complete.

 ShiftTime ID Shift FromTime ToTime Descriptioin 1 1 05:55 07:55 10 mins tea break 2 1 08:05 09:55 30 min lunch break 3 1 10:25 12:30 10 min tea break 4 1 12:40 14:30 End of 1st Shift. 5 2 15:01 17:00 10 min tea break 6 2 17:10 19:30 30 min lunch break 7 2 20:00 21:50 10 min tea break 8 2 22:00 23:35 End of 2nd Shift.

StandaredTime

 ID Stage StageName StandardTime(MINUTE) 1 1 WELD 600 2 2 PAINT 800 3 1 ASSEMBLY 800 4 1 QC 200

So I have to calculate the delay time for one work/process.

Case 1 - Support Today there are only two shift. Process1 got started on  2nd shift at 18:30 and StandardTime is  10 Hours to complete the process and suppose it got finished next day 1st shift. So. Calculation would be something like this.

23:35(End of 2nd shift of first day) – 18:30 (Process starting time) –00:30 mins (Lunch break) – 00:10 (mins tea break) = 4:25 mins. Job is done. Next 5:30 mins job will be done on next day 1st shift. Next day calculation would be the same like.

5:55 am + 5:35 (hr job remain)  + 30 min (lunch break)  + 10 min (tea break). So the work should be finished by 12:00 AM afternoon.

And Holiday also I have to calculate. And I need to add to this holiday to calculate delay.

6        1                  2009-01-06 00:00:00.000

Note : NoOfShift 0 means holiday for that day.
