Discuss several disadvantages of linear programming, clearly explaining the reasons for your choices

ANSWER:

A linear programming requires the objective and the constraints to be linear, which in real life is not always true.

A linear programming always has only one objective either to maximize the returns or minimize the costs. In reality there might be some other objectives as well.

Linear programming assumes that the values of coefficient of decision variables are known with certainty. It cannot be applied where the values of coefficient are unknown or probabilistic.

Parameters are not always constant as assumed under a linear programming.

The decision variables can be non-negative integer or fractions. If the situation requires an integer solution then, rounding off the solution is not always optimal.
