Scheduling Issue

[Former Member]

Hi Friends, 

Your advice is solicited for the below issue.

Shift per day- 2 (1st shift 6am to 2pm, 2pm to 10pm, 3rd shift non working)

Finished Material - A

Routing of A has 4 operation for lot size 500000 pcs

Operation 1- granulation --- time required for 500000 pcs 4hr

Operation 2- encapsulation --- time required for 500000 pcs 130hr

Operation 3- coating  --- time required for 500000 pcs 7hr

Operation 4- drying  --- time required for 500000 pcs 4hr

Resource for encapsulation is a container, on which we can load components maximum for 50000 pcs and take 13hrs to complete. Operator only starts the machine encapsulation only when there is 13hr is available in resource capacity, that means if he starts today morning at 6am one lot so he will complete this lot by 7pm, and after 7pm he will keep the encapsulation machine idle for next 3hr of 2nd shift.

Please suggest a solution for scheduling.

Dear,

Please create a new shift start at 6:00 hrs and end at 19:00 Hrs as assign it to encapsulation work center only as you keep this machine Idle after that also you start encapsulation machine next day 6:00 Hrs.

Could you please try this and come back.

Hi Brahmakar,

Not all meterial will behave the same way as material "A" , means material B will need 16 hour to complete a lot(part of a process order). Actually the constraints are : 1) Orders might be splitted into several lots as per machines capacity(capacity varies material to material).  2) If user start one lot in a machine it should be completed in that day itself.

Dear,

I don't think it is possible to map this in standard SAP. Better to have 16 Hrs as available capacity.

Product A will have 13 Hrs of machine time and Product B will have 16 Hrs of machine time in routing.

Yo can do the capacity planning in CM25 and dispatch the particular operation as per the constraints. You can keep machine idle by dispatching further operation on next day.

Hope it will help you.
