Unformatted text preview: for j = 1 ,...,n What are the data in this model? Why are these quantities data? Solution: p j ,a i,j ,b i ,d j represent data , because they are predetermined numerical values. x j represent decision variables whose values still to be determined by solving the optimization model, they are NOT data in this model. 1...
