LP has turned to be a highly useful tool of analysis in development planning. But its efficiency is restricted due to;
It is not easy to define a specific objectives function.
Even the objectives function is defined; it may not be easy to find out various social, institutional, financial
and other constraints which may restrict in pursing the given objectives.
Given a specific objective and set of constraints, it is possible that constraints may not be directly expansible as linear inequalities.It is difficult to estimates various constant coefficient that enter into a LP problem.
LP is based upon relative relations between input and output. This means that input and output are additive, multiplicative and divisible. But the relation between input and output are not always linear. Most of relations are non-linear.Perfect competition is not found practically.LP is based upon CRS but in real life there is either IRS or DRS.
It is highly mathematical a complicated techniques. Particularly simplex method involves a large number of mathematical
calculations.
Most of LP models are based upon trial and error solutions and it is difficult to find out really optimal solutions to various economic problems.
So all these limitation are based upon the economic problems.

It takes out the personal angle in decision making.
LPP deals with solving problems which are linear . ex: simlpex method, big m method, revised simplex, dual simplex. NLPP deals with non linear equations ex: newton's method, powells method, steepest decent method
Linear programming, especially in economics is vital for being able to make accurate estimates of goods output, costs and stock levels needed to carry out certain tasks. It is best to assume that the conditions do not change drastically.
There are two types of limitations of stock exchange in economy; economic limitations and personal limitations. Economic limitations refers to when companies back off from investing due to fears, and personal limitations refers to small investors not being able to impact the stock exchange by investing.
The three limitations of bartering are desirability, transferability and divisibility.

A linear objective function and linear constraints.
Integer programming is a method of mathematical programming that restricts some or all of the variables to integers. A subset of Integer programming is Linear programming. This is a form of mathematical programming which seeks to find the best outcome in such a way that the requirements are linear relationships.

Linear programming can be used to solve problems requiring the optimisation (maximum or minimum) of a linear objective function when the variables are subject to a linear constraints.
