Dual value is a concept that stems from the field of mathematical optimization and plays a crucial role in understanding the duality of linear programming problems. It is an integral part of various decision-making processes and plays a significant role in understanding the sensitivity of variables in linear programming models. The concept of dual value allows us to determine the maximum amount by which the objective function value can be increased or decreased if constraints are relaxed or tightened within certain limits.<\/p>\n

At its core, dual value measures the rate of change of the optimal value of a linear programming problem with respect to changes in the right-hand side (RHS) of the constraints. In other words, it tells us how much the objective function value will change if the resources allocated to specific constraints are increased or decreased. By considering the dual values associated with the constraints, we can assess the impact of changes on the overall solution and make informed decisions accordingly.<\/p>\n

What is dual value?<\/strong><\/p>\n

Dual value, also referred to as shadow price or marginal value, is a numerical value assigned to each constraint in a linear programming problem. It represents the amount by which the objective function value will change for a unit increase in the right-hand side of the respective constraint, while keeping all other constraints and the optimal solution unchanged.<\/p>\n
