Kohdefunktioiden

Kohdefunktioiden (target functions) are mathematical functions used in optimization problems to represent the objective that needs to be minimized or maximized. They are fundamental in various fields such as operations research, economics, and engineering. A target function typically takes a set of input variables and produces a single output value, which is the quantity to be optimized.

In mathematical terms, a target function can be represented as f(x), where x is a vector of decision variables and f(x) is the objective value. The goal of an optimization problem is to find the values of x that either minimize or maximize f(x), subject to a set of constraints that define the feasible region.

Target functions can be linear or nonlinear, depending on the relationship between the input variables and the output value. Linear target functions are simpler to solve and are often used in linear programming problems. Nonlinear target functions, on the other hand, can be more complex and may require advanced optimization techniques to solve.

In practical applications, target functions are used to model real-world problems, such as minimizing production costs, maximizing profit, or optimizing resource allocation. By defining an appropriate target function and constraints, decision-makers can use optimization techniques to find the best possible solution to a given problem.
