Operation priority scheduling as per capacity utilization.

Question

Hi friends
Our client wants  to set operation wise priority.In our case there is only one operation  in that worcenter.
Routing master data is set like that. we had given overlapping-. continous prodction and Minahead qty 1 PC.
Iif there are  more  production orders using  same workcenter, now he want set capacity utilisation like this.
                            WC1             WC2           WC3        
Order A               40%                                 50%
Order B               30%              40%
Order C               40%              60%            50%
After this system has to schedule the orders/operations  accordingly ..
This is for schedulig Planning purpose as per the demand.
we are using MTS and in MRP lead time scheduling.
One more thing
If there are three orders starting on same date  using same workcenter 
when we are checking the orders system has scheduled for three orders -operations staring on same time
Order A Operation 0010 WC1- start 7:00 hrs
Order B Operation 0010 WC1 start 7:00 hrs
Order C Operation 0010 WC1 start 7:00 hrs
If i am checking capacity icon system has given available capacity for this workcenter
How come all orders start at same time even capacities are available.

Srihari,
How come all orders start at same time even capacities are available.
You have only mentioned MRP.  MRP is not intended to schedule orders according to capacity, it only plans for making materials available at the required times.  In order to plan for capacity consumption, you need to carry out capacity planning.

To answer your question, it is sometimes desirable to have many orders start at the same time in a specific work center, even after capacity planning has been done.  This is dependent upon the client's business requirements and the structure of his manufacturing operations.
If you have never implemented capacity management before, I suggest that you speak to a senior PP consultant on your team, who should be able to show you how to get basic CRP set up and running.
