Hello, I contact you because I have some concerns about the calculation of an optimal coefficient. I join you the document opposite because it seems to me that it will be for you simpler to follow my concern in this way.

I explain you: CARPmax;Pmax and CARPmin;Pmin are two couple of points which form me a line of affine of equation :

CAR=(((CARPmax-CARPmin)*(P-Pmax))/(Pmax-Pmin))+CARPmax. So for a given power P, I naturally have my CAR.

I now want to know how to distribute this power on two identical machines to obtain the best global CAR for a given power requirement Pnéc.

So we will have a first machine with a Power Distribution 1 with a Power equal to x*P with x a coefficient between 0 and 1.

On the other hand, we have the second machine which works in addition with a power Distribution Power 2 equal to (1-x)*P.

Each machine has therefore at this given power, a CAR that corresponds to it (calculated with the affine function seen previously).

I am looking for the optimal value of x to have the maximum CAR which is calculated as follows:

(CAR distribution P1*DistributionP1+CAR distribution P2*Distribution P2)/Pnéc and I don't know how to do it :(

I thank you in advance for your precious expertise :) :)
