The proportionality property of LP models means that if the level of any activity is multiplied by a constant factor,then the contribution of this activity to the objective function,or to any of the constraints in which the activity is involved,is multiplied by the same factor.

The proportionality property in Linear Programming (LP) models states that the contribution of any activity to the objective function and any constraints is directly proportional to the level of that activity. Therefore, if the activity level is scaled by a constant factor, its contribution to both the objective function and any relevant constraints is also scaled by the same factor. This property is fundamental to the linear nature of LP models, ensuring that relationships between variables and outcomes are linear and directly proportional.
