It is only as good as the data that is input. If the data is bad, the results will be bad. The best way to get good results of linear programming is to make sure that your data is set up properly and is accurate. so it depend on the data to determine the solution for the problem

It is not simple to specify the constraints even after the determination of a given function.

Determining the given function mathematically in a linear programming problem is quite difficult.

limitations of linear programming are linearity, convexity, multiple objectives, human factors etc.
