    I have 3 resources and 4 cloud providers. I would like to know which provider is the cheapest one, for all products combined. Cplex can't find a solution because there is a problem with the constraints.

      CP1 CP2 CP3 CP4
    Resource1 10 20 25 30
    Resource2 20 10 40 20
    Resource3 25 10 30 10
    Total Summation 55$ 40$ 95$ 60$


    The result of the is LP is "CP2" because it has minimum summation of the costs. I am not sure if the constraints are correct or not, because I don't get a solution at all.

     

    Here is the mathematical model, where "r" is resources, "c" is cost, "p" is provider and "X" is decision variable

    The new constraints of the problem are as follows:
