Use the Italian restaurant example for guidance. Begin with the optimal tableau and replace the 0 under b with -Δ b assuming b as a basic column. The disallowance of a nonzero in row 0 demands taking action to pivot it out. Pivot this out using the line of the optimal tableau that represents 0.20 g + 1.00 b + 0.04 s 1 - 0.60 s 2 - 0.60s 4 = 0.10 Now do the cut-and-paste with the optimal tableau again with these changes: 0.60 + 0.20Δ b under g (I) 0.32 + 0.04Δ b under s 1 (II) 2.20 - 0.60Δ b under s 2 (III) 1.20 - 0.60Δ b under s 4 (IV) 4.80 + 0.10Δ b under RHS (V) For which values is each (I) - (IV) nonnegative? Don't worry about (V): RHS can be +, -, or 0. (I) Δ b >= -3 (II) Δ b >= -8 (III) Δ b <= 3.666. .. (IV) Δ b <= 2 The interval of values for which satisfies all four is -3 <= Δ b <= 2.

Unformatted text preview: solution will change. You can decrease the objective coefficient of beer by 3 before your solution will change.----------When using http://people.hofstra.edu/Stefan_Waner/realWorld/simplex.html The solution c = 0.2 i = 0.4 g = 0.0 b = 0.1 h = 0.3 stays the same, although z drops, when the coefficient of b in the objective function is reduced to as much as 7. However, if you try to go farther it changes the solution. 7 = 10 - 3 The solution c = 0.2 i = 0.4 g = 0.0 b = 0.1 h = 0.3 stays the same, although z goes up, when the coefficient of b in the objective function is increased to as much as 12. However, if you try to go farther it changes the solution. 12 = 10 + 2....
