Looking for Python help with My project.

Hi everyone, In short, my work foucus when there is a supplier serves one , and two customers (separately), over different time (R , day, week), and if the supplier doesn't achieve the the target of filling the demand he will get a penalty. What I have (2 formulas, for one customer, and two customers as well) with their codes. And I get the results. with X-axis (S which is stock level (the supplier stock the units)) with Y-axis with Cost (of the penalty). and you can see the attached. the notations in the codes: Vo(S) = the supplier penalty. S = stock level (from range 0 -20) D = demand (how much demand) h = holding cost = 1 R = the time (review period) day, week K = penalty (in the case one customer) K1, K2 = penalty for customer one and customer 2(in case two customers) Now, I need to set up the Vo(S0 (cost)) = 300 or around this number , and S = 12, and play randomly (every time put any number for penalty (K) to reach for the cost =300), over different R, with K. in the case of 2 customers (K = K1= K2) I have attached the details on the words file explain what I need which is easier, the codes for one and two customers, and example. I hope to discuss with someone over Skype, if it is required and understand clearly. I have explained everything on the Word file. I don't have more time please looking for someone is good.
