parallel sequence - scheduling operation

Hi,

when I was creating parallel sequence in routing I was faced with problem in scheduling operation.

After making a routing with parallel sequence, which are executing on the others work centers, system doesn’t take into consideration the fact that order is divided on for example two work centers ( parallel sequence ! ).

How to divide the time of operations for equal parts ( or different proportion ) in two work centers.

Please help me solvede this problem.
