An example of sensitivity analysis- Need Help

Hello,

I want to check the sensitivity of my proposed model. But i can't build my model on my mind to excel.

In the attached file

to find positive and negative solutions, co-co multiplied by product.

But I want to check the effect of criteria. To check it for C1 row, weight column rows' added and results is coming iteratively row by row.

For example

for c1, weights are iteratively inserted. firstly, .79 .46 .18 then .12 .82 .24... and it's going like this. After this positive and negative solutions is changing. And the ranks must be kept.

For every weight the algorithm runs same.

How can I do this? Can anyone give me some hints?
