Question

Give the dafination of 'decision variable' associated with linear programming

Answer 1

Answer:

Decision variables describe the quantities that the decision makers would like to determine. They are the unknowns of a mathematical programming model.

Explanation:

Typically we will determine their optimum values with an optimization method. In a general model, decision variables are given algebraic designations such as . The number of decision variables is n, and is the name of the jth variable. In a specific situation, it is often convenient to use other names such as or or . In computer models we use names such as FLOW1 or AB_5 to represent specific problem-related quantities. An assignment of values to all variables in a problem is called a solution.
