How to Process Data by referencing a Function

[StoffStoff]

Hello Everyone,

I want to process 3 variables to give me 1 output. These 3 variables will be processed several times to generate that particular output. The problem is similar to this example:

Input data x, y , z gets processed by Process 1 and 2 to generate output F. How could I process the x,y,z data without having to reenter each x,y,z data set to calculate F ?

This is just an example , the actual problem has over 8000 data sets and about 12 elaborate processes and I just dont have the time to enter so many data points. What would be the quickest and most efficient of processing the data without rearranging the actual process setup?

I have attached the excel file to the thread. Any help would be appreciated.
