Shadow price, an essential concept in linear programming and economic analysis, can be complex to understand. A Shadow Price Calculator simplifies this complexity by providing a straightforward way to calculate the shadow price in various economic and optimization scenarios. This tool is vital for businesses, economists, and researchers who deal with resource allocation problems.

Formula of Shadow Price Calculator

The fundamental formula used in the Shadow Price Calculator is:

Shadow Price (SP) = Change in Objective Function Value / Change in Right-Hand Side (RHS) Value

Variables in the formula:

  • Shadow Price (SP): This is the result of the calculation. It represents the rate of change in the objective function value (like profit or cost) per unit change in a constraint’s RHS value.
  • Change in Objective Function Value: This refers to the variation in the objective function’s value due to a unit increment in the RHS value of a constraint.
  • Change in Right-Hand Side (RHS) Value: It indicates the alteration in the RHS value of a constraint for which the shadow price is calculated.

General Terms and Calculator Conversions

This table provides a quick reference to common terms and conversion factors that are useful when using the Shadow Price Calculator. It’s designed to aid users in understanding and applying the calculator more effectively without needing to perform each calculation manually.

TermDefinitionExample Conversion or Value
Objective FunctionThe function representing the goal of the optimization, such as maximizing profit or minimizing cost.For a production company, profit maximization.
ConstraintA limitation or condition that must be satisfied in the optimization problem.Resource availability, such as labor hours or materials.
Right-Hand Side (RHS) ValueThe value on the right side of a constraint equation, representing the limit or availability of a resource.100 units of a resource.
Unit Change in RHSThe increment or decrement of one unit in the RHS value.Increasing or decreasing the resource limit by 1 unit.
Change in Profit/CostThe variation in the objective function due to the change in the constraint.$500 increase in profit for one additional unit of resource.
Shadow Price (SP) ValueThe calculated shadow price per unit change in the RHS value.$500/unit, indicating the profit change per unit increase in resource.

This table serves as a practical guide, helping users to understand the key terms and their implications in the calculation of the shadow price. It enables a more intuitive grasp of the formula and its applications in various scenarios.

Example of Shadow Price Calculator

Consider a production company seeking to maximize profits under certain resource constraints. By inputting the change in profit (objective function value) and the change in resource availability (RHS value) into the Shadow Price Calculator. The company can determine the shadow price. This value informs them how much the profit could increase for each additional unit of the resource, aiding in strategic decision-making.
