Sensitivity Analys

• What happens when a constraint changes?
• Is the constraint key to the current solution?
• How much does it have to change before it affects
  what we choose to do?
• What happens if the objection function
  coefficients change?
• How much does it have to change before it affects
  what we choose to do?
• Important because of the constantly changing
  environment

Sensitivity Analysis

• Dont have to refigure each time If we know the
  sensitivity analysis then we do not need to
  recalculate every time a constraint or
  coefficient changes
• Risk How much risk do we have with the
  solution?
• Different Types of Changes Coefficient changes,
  constraint changes, simultaneous changes

4
Coefficient Changes

• Changes to the objective function
• Lower Limit What is the lowest coefficient that
  keeps the same solution?
• Upper Limit What is the highest coefficient
  that keeps the same solution?
• Current Value Where are we currently at?
• Simultaneous Changes 100 percent rule!
• Question If we are within the coefficient range
  would a change affect the objective function
  value?

5
Right Hand Side Changes

• Changes to the constraints
• Lower Limit What is the lowest right hand side
  constraint that keeps the same solution?
• Upper Limit What is the highest right hand side
  constraint that keeps the same solution?
• Current Value Where are we currently at?
• Question If we are within the coefficient range
  would a change affect the objective function
  value?

6
Right Hand Side Changes

• Dual Price The improvement in the value of the
  optimal solution per unit increase
• Sample (Objective Function Value 1400)
• Dual Price is 5.33
• If the problem is a minimization one, what is the
  new value of the objective function?
• If the problem is a maximization one, what is the
  new value of the objective function?
• Dual Price is -10
• If the problem is a minimization one, what is the
  new value of the objective function?
• If the problem is a maximization one, what is the
  new value of the objective function?
