What is Linear Programming?
Linear programming is a mathematical technique that helps decision-makers optimize their resources by providing organizing frameworks to allocate resources efficiently. In essence, linear programming provides a way to model an ideal solution to a problem given a set of constraints. The end result is a mathematical formula that helps people optimize their resources.
Steps to Creating Linear Programming Models
Creating a model requires several sequential steps, starting with defining the objective function, followed by defining the constraints, and selecting relevant decision variables.
Step 1: Define the Objective Function
The objective function expresses the goal of the model in quantitative terms. It usually seeks to maximize or minimize a particular metric. For example, if the objective is to minimize cost, then the objective function would be a cost function such as the total cost of running a factory, or the cost of producing a certain number of goods.
Step 2: Define the Constraints
Constraints are the specific conditions that must be obeyed to meet the objective function. Constraints can be hard or soft, where hard constraints are mandatory and cannot be violated, while soft constraints can be relaxed under certain conditions. Constraints can be expressed in the form of mathematical equations or inequalities. For example, constraints may include not exceeding a stated budget or a specific production limit.
Step 3: Select Relevant Decision Variables
The decision variables are the quantities of resources that are directly controlled by the decision-makers. In other words, these are the resources that they can change in order to improve the objective function while still satisfying the constraints. Certain decision variables may be either continuous or discrete. For example, if a decision focuses on business activities, then decision variables may include the amount of product produced, the amount of time spent working, or how much a supplier would be willing to deliver in a given time frame.
Benefits of Linear Programming Models
Linear programming models help businesses and organizations in various fields, including finance and economics. By using these models, companies and organizations can effectively manage their resources, reduce costs, and increase productivity. For example, linear programming can be used to optimize production levels for a large-scale production facility or to develop an efficient shipping plan for a shipping company. In general, optimizing resource allocation in any field can ultimately lead to increased profits and a more resourceful future.
