Operations Research Class work3: Chapter 4: Sensitivity Analysis for LP solutions Exercise 1 We consider the following LP problem. We use basis {x1, x2, 5). Max 2x1 + 3x2 x1 - x2 + x3 -10 x1 + x2 - 30 x! +x520 x1, x2, x3, x4, x5 20 Find ranges for individual coefficients of the objective function and for rhs coefficients. Exercise 2 We consider the following LP problem. We use basis {x1, x2, x4,x6}. Max 1170 x1 + 1110x2.400 x6 9xl + 5 x2 + x3 - 500 7x1 + 9 x2 + x4 = 300 5x + 3x2 - X5 - 1500 2 xl + 4x2 - x6 =1000 xl, x2, x3, x4, x5, x6 2 0 Find ranges for individual coefficients of the objective function and for rhs coefficients
