1) Linear Programming Limitations [Provide detail explanation in 2000 words and type your answer and do not copy the answer from chegg study ]
1. Linearity of relations: A primary requirement of linear programming is that the objective function and every constraint must be linear. However, in real life situations, several business and industrial problems are nonlinear in nature.
2. Single objective: Linear programming takes into account a single objective only, i.e., profit maximization or cost minimization. However, in today's dynamic business environment, there is no single universal objective for all organizations.
3. Certainty: Linear Programming assumes that the values of co-efficient of decision variables are known with certainty. Due to this restrictive assumption, linear programming cannot be applied to a wide variety of problems where values of the coefficients are probabilistic.
4. Constant parameters: Parameters appearing in LP are assumed to be constant, but in practical situations it is not so.
5. Divisibility: In linear programming, the decision variables are allowed to take non-negative integer as well as fractional values. However, we quite often face situations where the planning models contain integer valued variables. For instance, trucks in a fleet, generators in a powerhouse, pieces of equipment, investment alternatives and there are a myriad of other examples. Rounding off the solution to the nearest integer will not yield an optimal solution. In such cases, linear programming techniques cannot be used.
6. TRIAL AND ERROR SOLUTION : . Mostly, linear programming models present trial-and-error solutions and it is difficult to find out really optimal solutions to the various economic problems.
7. COMPLICATED : It is a highly mathematical and complicated technique. The solution of a problem with linear programming requires the maximization or minimization of a clearly specified variable. The solution of a linear programming problem is also arrived at with such complicated method as the ‘simplex method’ which involves a large number of mathematical calculations.
