Introduction to Operations Research / Linear Programming Solver
Operations Research (OR) involves using advanced analytical methods to help make better decisions. Linear Programming (LP) is a mathematical technique within OR used to optimize a linear objective function, subject to linear equality and inequality constraints. The Linear Programming Solver is a tool designed to solve these optimization problems. Its primary purpose is to find the best possible outcome (such as maximum profit or lowest cost) given a set of constraints. For instance, a company might use an LP solver to determine the optimal mix of products to manufacture that maximizes profit while staying within budget and resource limits.
Main Functions of Operations Research / Linear Programming Solver
Optimization of Linear Objective Functions
ExampleMaximizing profit in a manufacturing process while minimizing costs.
ScenarioA factory produces multiple products, each with different costs and selling prices. The LP solver determines the optimal production levels of each product to maximize total profit, considering constraints like labor hours and material availability.
Integer Programming
ExamplePortfolio selection in investment planning.
ScenarioAn investment firm needs to allocate funds among various stocks to maximize return while adhering to constraints such as budget limits and risk diversification requirements. The solver ensures that the investment in each stock is an integer number of shares.
Network Flow Optimization
ExampleOptimizing transportation routes.
ScenarioA logistics company aims to minimize transportation costs by determining the best routes for shipping goods from multiple warehouses to various destinations, taking into account constraints like route capacities and delivery deadlines.
