Study Notes

Linear Programming Objectives

The main objective of business decisions involving linear programming is to maximize or minimize a specific objective, such as profit or cost.

Decision Variables

Decision variables in linear programming represent the choices or decisions that a firm or organization can make.
They are the variables that are controlled by the decision-maker.

Objective Function

The objective function in linear programming represents the goal or objective of the decision-maker.
Its purpose is to define the optimization problem, specifying what to maximize or minimize.

Application of Linear Programming

The steps involved in the application of linear programming include:
- Formulating the problem
- Defining the objective function and constraints
- Solving the problem using optimization algorithms
- Interpreting the results

Representation of Firm's Decisions

Linear programming uses decision variables to represent a firm's decisions.

Irregular Linear Programming Model

An example of an irregular type of linear programming model is the integer programming model.

Constraints

Constraints in the context of model formulation represent the limitations or restrictions on the decision variables.

Parameters

Parameters in model formulation represent the known constants or coefficients that affect the decision variables.

LP Model Formulation

The objective of LP model formulation is to find the optimal solution that maximizes or minimizes the objective function.
Decision variables in LP model formulation represent the choices or decisions that a firm or organization can make.
Non-negativity constraints are used to ensure that the decision variables are not negative.
A feasible solution in LP model formulation is a set of values for the decision variables that satisfy all the constraints.
An infeasible solution implies that it is not possible to find a set of values for the decision variables that satisfy all the constraints.
The objective function in LP model formulation defines the optimization problem, specifying what to maximize or minimize.
Parameters in LP model formulation have a fixed value and are not affected by the decision variables.

Product Mix Problem

A product mix problem in LP model formulation involves determining the optimal mix of products to produce, given the available resources and constraints.
