Numerical Model of LPP:- Objective:- The main objective is long-run profit maximization and find optimal production Quantity (Mix). The measure of effectiveness: The measure of effectiveness is profit obtained from each type of models so as to determine the optimal Read more…


Confidence intervals consist of a range of values (interval) that act as good estimates of the unknown Population parameter. However, the interval computed from a particular sample does not necessarily include the true value of the parameter. Confidence intervals were Read more…


Mathematical Model of LPP:- The general mathematical model of LPP (or model) with n decision variables and m constraints can be stated in the following form :   There are some limitations associated with this technique. These are the following:- Read more…


Linear Programming Problem is a mathematical technique for finding optimal solutions to problems. Its problems expressed using linear equations and inequalities. The real-world problems represent accurately by the mathematical equations of a linear program also this method will find the Read more…
