Hi Rashid,

There are two methods to define your resources and having same results. The first method is to use the resource shift calendar and the second methods is create two resources.

"If we have an activity that needs 20 hours of work i.e. a day and a night and for example a resource such as fitters vary in number during the day and night shift, 10 in day and 5 at night. How will we model this situation?"

First you need to create a calendar say “2shift calendar” under Enterprise-> Calendar and click Add. Define the working hours - Click modify then select detail work hours per day. Highlight Mon-Sat and select 6:00 to 23:00 and click work. Select again 0:00-2:00 and click work. Select 3:00-5:00 and click non work. Now you have a 20hrs/day calendar Mon-Sat. Assign this calendar to your task/ activity that requiring shifting.

1st method:
a)     Create a resource shift calendar – Select Enterprise-> Resources shifts on your menu
b)     Enter any name say “2-shifts operation” and click modify
c)     Click Add and enter the start hour say: 6:00, then click add again and enter 16:00, then click add again and enter 2:00. You should have 24 hours total on 3 shifts i.e. 4, 10 & 10. Remember the shift number because you’re going to used it when defining the resource.
d)     Create a resource say i.e. fitter – Select Enterprise-> Resources.
e)     Click add icon on the right and Enter Fitter as Resource Id and Fitter as Resource Name.
f)     Click Unit & Prices tab and click shift calendar. Select the new resource shift calendar created “2-shift operation”
g)     Delete the first shift shown on the effective date. (I assume shift 1 = 4 hours)
h)     Click shift up to 2 and change 100/day (EQ to 10 fitter per day assuming this is day shift as define on your resource shift)
i)     Click shift up to 3 and change 50/day (EQ to 5 fitter per day assuming this is nightshift as define on your resource shift)
j)     Click Detail tab and change 10/d on your Default Unit/ Time and change calendar to “2-shift operations”
k)     Now assign these resources to your activity and you should have a 15fitter/d or 150hr/d on your resources through out the duration of your activity.

2nd Method:
Assuming you already define “2shift calendar” attached to your task/ activity.
a)     Define two more calendar say: “Day shift” and set the working time mon-sat 6:00-16:00 and “Night Shift” set working time mon-sat 16:00-2:00.
b)     Define two resources say fitter1 & fitter2.
c)     On fitter1 set your max units/time by 100/d under unit & prices tab and change the calendar to “Day shift” and change Default units/ time to 10/d under Detail tab.
d)     On fitter2 set your max units/time by 50/d under unit & prices tab and change the calendar to “Night shift” and change Default units/ time to 10/d under Detail tab.
e)     Assign both resources to your task/ activity and you should have 100/d & 50/d shown on your resources assignment through out the duration of your activity.

Both of them having same result but shown differently on your resource assignment.
Cheers,
Rodel

VERY IMPORTANT

The Primavera resource hierachy is designed for named user resources so duplicates are not allowed e.g.

Location1.fitter
Location2.fitter

Is NOT allowed, as you have used "fitter" twice in position 2 of the hierarchy.

SO, you need to call the resources

Loc2-fitter
Loc1-fitter

as only the "Dot" character is recognised as the hierarchy delimiter. The above two IDs use 11 characters of the 20 allowed in each position.

Have fun!

We do this here. Multiple offshore oil platforms where they all have fitters, and we can hardly hire a fleet of helicopters so that they can all be used interchangably.

There is no way out of using a different resource ID for each location’s pool of tradesmen. They ARE seperate resources after all, because they cannot be shared- I don’t see any problem with this.

All the various resources e.g. Fitter-loc1, Fitter-loc2 share a "role" of Fitter, and resource codes for location, so an "all fitter" resource report, or manning levels by location are easy.
