Developing A Linear Programming Model A
Comprehensive Homework Blueprint
2
  • Linear Programming is an essential mathematical
    optimization technique and is commonly applied in
    areas such as statistics and operational
    research, and management. Whether your tasks
    involve managing production schedules, working on
    budgets or optimizing resources, linear
    programming knowledge is vital. This presentation
    offers a step-by-step guide that students can
    follow as they work through the process of
    creating a Linear Programming Model effectively,
    backed by real-world examples, helpful resources,
    and expert tips.

3
Introduction toLinear Programming
4
  • Linear programming is an optimization technique
    to realize the best solution for the given
    mathematical problem, where its constraints are
    described using linear relationship. It is
    applied in different fields including economics,
    business, engineering, and military applications,
    in order to improve the processes and make right
    decisions.

5
Key Components of a Linear Programming Model
  • Objective Function This means that the
    optimization is usually performed with an aim of
    maximizing or minimizing a particular value.
  • Decision Variables The values that the
    decision-makers are going to decide in order to
    optimize the objective function.
  • Constraints These are the conditions or
    constraints to decision variables in the form of
    linear equations or inequalities.
  • Non-Negativity Restriction The decision
    variables cannot be negative which implies that
    the values of the decision variables will be
    greater than zero..

6
Steps in Developing a Linear Programming Model
7
  • Identify the Objective Define what needs to be
    maximized or minimized, such as profit, cost,
    time, or resources.
  • Determine the Decision Variables These are the
    unknowns that you want to solve for. For
    instance, if you are deciding how much of two
    products to produce, these amounts would be your
    decision variables.
  • Formulate the Objective Function Express the
    objective in terms of the decision variables. For
    example, if your goal is to maximize profit, your
    objective function could be Zc1x1c2x2 ?, where
    c1? and c2? are the profits per unit of products
    x1? and x2?, respectively.

8
  • Establish the Constraints Constraints might
    include resource limitations, such as available
    labor hours or material quantities. These should
    be expressed as linear inequalities. For example,
    if a process requires 2 hours of labor per unit
    of product x1 and 3 hours for x2?, and you have a
    total of 100 labor hours available, the
    constraint would be 2x13x2100.
  • Solve the Linear Programming Model Use methods
    such as the Simplex algorithm, graphical method,
    or computational tools like Excel Solver or
    specialized software to find the optimal
    solution.

9
Example A Simple Linear Programming Model
10
Scenario
  • The production data of the company shows that two
    products, product A and product B are made and
    the profit per unit of the former is 40 while
    for the latter 50. The company is initially
    equipped with 200 hours of labor and 300 units of
    raw material. In productions of product A, one
    unit needs 1 hour of labor and 2 units of
    material however, in productions of product B,
    one unit needs 2 hours of labor and 1 unit of
    material. The goals of the company are best
    achieved in this case by trying to achieve
    maximum profit.

11
Step-by-Step Solution
  • Objective Function Maximize Z40x150x2? where
    x1? and x2 are the quantities of product A and B,
    respectively.
  • Constraints
  • Labor 1x12x2200
  • Material 2x11x2300
  • Non-Negativity x1,x20
  • Solution Solving the model using graphical or
    simplex method gives the optimal production
    levels of products A and B that maximize profit
    while satisfying all constraints.

12
Tools and Software for Linear Programming
13
  • Excel Solver Microsoft Excel has in-built tools
    for solving linear programming problems of a
    small to medium size.
  • PYTHON Python is used these days to solve
    complex linear programming questions.
  • MATLAB MATLAB is perfect for other difficult LP
    problems with the help of the Optimization
    Toolbox.
  • Gurobi A high-performance tool for solving
    complex large-scale problems with high
    dimensionality.

14
Helpful Resources Textbooks
15
  • "Introduction to Operations Research" by
    Frederick S. Hillier and Gerald J.
  • Lieberman A comprehensive guide to linear
    programming and other operations research
    techniques.
  • "Operations Research An Introduction" by Hamdy
    A. Taha A well-structured textbook that offers
    clear explanations and practical examples.
  • "Linear Programming and Network Flows" by Mokhtar
    S. Bazaraa, John J. Jarvis, and Hanif D. Sherali
    A detailed exploration of linear programming and
    its applications.

16
Common Pitfalls in Linear Programming Homework
17
  • Misidentifying the Objective Function Clarify
    the goals that you are seeking to optimize.
  • Incorrectly Formulating Constraints Make sure
    that constraints do reflect the problem in
    question.
  • Overlooking Non-Negativity It is very important
    to incorporate the non-negativity constraints of
    decision variables.
  • Misinterpreting the Solution When solving,
    understand the results appropriately in order to
    apply them to the real-world situation.
