Linear programming method is a type of constrained optimization method of project selection. In this method, you look towards reducing the project cost by efficiently reducing the duration of the project. You look for running an activity in its normal time or the crash time.

The purpose of this paper is to demonstrate how such a problem can be formulated with relative ease into a linear programming model for use on most computers with a linear programming package. It will further be shown that a major advantage of such a model is the opportunity it provides to control the project during the implementation stage.

Let’s boil it down to the basics. Linear Programming (LP) is an attempt to find a maximum or minimum solution to a function, given certain constraints. It might look like this: These constraints have to be linear.

1. A Brief Introduction to Linear Programming. Linear programming is not a programming language like C++, Java, or Visual Basic. Linear programming can be defined as: "A method to allocate scarce resources to competing activities in an optimal manner when the problem can be expressed using a linear objective function and linear inequality constraints."

Solving this integer linear integer program is equivalent to the original problem of maximum independent set, with 1 value indicating that node is in the set. To get a tractable LP programme we drop the last constraint. If we solve LP without integer constraints and get integer valued result, the result is guaranteed to be correct.

Linear Programming Example. Let us see an example here and understand the concept of linear programming in a better way. Example: Calculate the maximal and minimal value of z = 5x + 3y for the following constraints. x + 2y ≤ 14. 3x – y ≥ 0. x – y ≤ 2. Solution: The three inequalities indicate the constraints. The area of the plane that will be marked is the feasible region.

For example, during the progression if the project, the project could fall behind or move ahead of schedule, which could ultimately lead to a modification of the project management plan. This could result in modifying the early start date.

Linear programming can be considered as providing an operational method for dealing with economic relationships, which involve discontinuities. It is a specific approach within the general framework of economic theory. The main similarities and differences between traditional economic analysis and linear programming may be outlined as follows.

By default Calc ships with a solver engine for linear programming only. This allows the optimization of models to a certain degree. However, if the formulas or constraints become more complex, nonlinear programming is required. That missing gap is now filled by the Solver for Nonlinear Programming extension.

Oct 15, 2015 · The optimum solution to the linear programming problem (if there is one) occurs at the corner point of the feasibility region.

functions involved are nonlinear. If the functions f(x,y), g(x,y), and h(x,y) are linear (or vacuous), then (1.1) corresponds to a mixed integer linear program (MILP). Further, for MILPs, an important case occurs when all the variables are integer; this gives rise to an integer programming (IP) problem.
