Many other industries rely on linear programming to enhance the economy of their business.  These include:

• The military
• Capital budgeting
• Designing diets
• Conservation of resources
• Economic growth prediction
• Transportation systems (busses, trains, etc.)
• Strategic games (e.g. chess)
• Factory manufacturing

All of these industries rely on the intricate mathematics of linear programming.  Even farmers use linear programming to increase the revenue of their operations, like what to grow, how much of it, and what to use it for.  Amusement parks use linear programming to make decisions about queue lines.  Linear programming is an important part of operations research and continues to make the world more economically efficient.
