The Solution
Contents
Solving the model, we get the following nonzero values for TD:
Variable Value
TD( U, 7) 10.00000
TD( B, 7) 20.00000
TD( T, 8) 20.00000
TD( S, 6) 30.00000
TD( S, 7) 40.00000
TD( W, 4) 50.00000
TD( W, 5) 40.00000
TD( C, 6) 20.00000
TD( C, 7) 40.00000
TD( H, 3) 50.00000
TD( H, 4) 40.00000
TD( P, 2) 1800.000
TD( P, 3) 1440.000
TD( L, 4) 1680.000
TD( L, 5) 3360.000
