- Linear programming is applicable only to problems where the constraints and objective function are linear i.e., where they can be expressed as equations which represent straight lines. In real life situations, when constraints or objective functions are not linear, this technique cannot be used.
- Factors such as uncertainty, weather conditions etc. are not taken into consideration.
- There may not be an integer as the solution, e.g., the number of men required may be a fraction and the nearest integer may not be the optimal solution.
i.e., Linear programming techqnique may give practical valued answer which is not desirable.
- Only one single objective is dealt with while in real life situations, problems come with multi-objectives.
- Parameters are assumed to be constants but in reality they may not be so.
