PRACTICAL STEPS INVOLVED IN FORMULATING DUAL PROBLEM FROM THE PRIMAL PROBLEM
The practical steps involved in formulating dual problem from the primal problem are as follows:
| Step 1→ | Ensure that in case of a maximization problem all constraints are of '≤' type or in case of a minimization problem, all constraints are of '≥' type.If not, adopt the following procedure: |
In case of Maximisation Problem
| Sign used in Constraints | Procedure |
|---|---|
| 1. '≤' type | No change is required. |
| 2. '≥' type | Convert the '≥' type inequality into '≤' type by changing the signs of all values appearing on left hand side and right hand side, (e.g. '+' sign into '–' sign, '–' sign into '+' sign). |
| 3. '=' type |
