ignizio.example.3.5 {goalprog} | R Documentation |
The data set that corresponds to Example 3-5 found in Ignizio (1976). These are examples of goal programming problems solved using the methods described by author.
Find
{mathbf{x}'} = [ x_1, x_2 ] ,
{mathbf{n}'} = [ n_1, n_2, n_3, n_4 ] and
{mathbf{p}'} = [ p_1, p_2, p_3, p_4 ] that minimize
mathbf{a} = [ (2 p_1), (n_2), (n_3) ]
The objectives are as follows
8 x_1 + 12 x_2 + n_1 - p_1 = 10000
x_1 + 2 x_2 + n_2 - p_2 = 40
x_1 + n_3 - p_3 = 30
x_2 + n_4 - p_4 = 15
mathbf{x}, mathbf{n}, mathbf{p} >= mathbf{0}
The solution is {mathbf{x}'} = [ 30, 15 ] and
mathbf{a} = [ 0, 580, 20, 0]
The data set is an R file that creates the coefficients matrix, the vector of target values and the data frame of achievement goals.
