Understanding Optimization Problems
Optimization is at the core of analytics, allowing you to make the best possible decisions given a set of options and limitations. In any optimization problem, you are trying to find the most favorable outcome—such as maximizing profit or minimizing cost—by carefully selecting certain values, called decision variables, while respecting a set of limitations, known as constraints. The objective is the specific goal you want to achieve, like increasing revenue or reducing delivery time. In analytics, these elements work together to create a structured problem that can be solved with mathematical methods and computational tools.
Structure of an optimization problem in analytics
-
Decision variables: what you control. For example, let x represent the number of products to make.
-
Objective: what you want to optimize. For instance, maximize profit: profit=revenue−cost.
-
Constraints: limitations or requirements. For example:
- x≤machine_capacity
- x≥minimum_order
Example mapping:
- x: decision variable;
- Maximize profit: objective;
- machine_capacity, minimum_order: constraints.
- Feasible region: the set of all possible values for decision variables that satisfy every constraint in the problem. Only solutions within this region are considered valid in analytics.
- Optimal solution: the best possible solution within the feasible region, according to the objective (such as the highest profit or lowest cost). In analytics, finding the optimal solution means making the most effective or efficient decision given all requirements.
1. Which component of an optimization problem is described in this scenario?
"A company must produce at least 200 units per week to meet demand."
2. In analytics, what does the term 'feasible region' mean?
