Hi all!

I built a feasible model in SG Navigator with 21 production plants and a detailed BOM per item and location. However, I must add constraints related to the total production per item and location during the period of analysis. 

I tried three ways but any of them worked: 

• Adding Minimum capacity and Force Open = 1 in the Production Sheet + Adding Minimum capacity per Location and Item in the Production Routing Sheet. Result = The model was infeasible 
• Adding Maximum capacity in the Production Sheet + Adding Minimum capacity per Location and Item in the Production Routing Sheet. Result = The model does not respect all of the constraints 
• Adding Minimum capacity and Maximum capacity (both of them with the same quantities) in the Production Sheet +  Production Routing Sheet. Result = The model was infeasible 

How should I model those constraints? 

Thanks!
