• Resource Allocation: Distributing limited resources to maximize profit or minimize cost (e.g., allocating time, money, manpower in production).
Detailed Explanation
Resource allocation is the process of distributing resources efficiently to achieve the best possible outcome, such as maximizing profits or minimizing costs. This can involve determining how much time, money, or labor to assign to various tasks. In linear programming, constraints ensure that allocations stay within the limits of available resources.
Examples & Analogies
Imagine a small bakery with a limited amount of flour, sugar, and labor hours. To maximize profit, the baker needs to decide how many cakes vs. cookies to make, considering how much of each ingredient is needed for each product. Linear programming helps find the best combination that maximizes profit without exceeding the available resources.

• Transportation Problems: Minimizing transportation cost while satisfying demand and supply constraints.
Detailed Explanation
Transportation problems focus on finding the most cost-effective way to distribute goods from multiple suppliers to multiple consumers. The goal is to satisfy the supply from each source and the demand from each destination while keeping transportation costs as low as possible. Linear programming can be used to set up the costs as part of the objective function and the supply and demand as constraints.
Examples & Analogies
Consider a company that needs to ship products from three factories to four stores. Each factory has a limited number of products available, and each store has a demand for a certain number of products. By using linear programming, the company can determine the most economical shipping routes and quantities, ensuring that all stores receive their products without overspending on transportation.
