Dependent and Independent Demand

Based on the text provided in the image, the core concept is how inventory is managed differently depending on what triggers the need for a product. Here is a simplified breakdown of the two types of demand:

1. Independent Demand

This is demand that comes directly from the customer or the market. It is "independent" because it doesn't depend on the production of another item.

* Characteristics: It is generally stable once you account for seasonal changes (like buying more coats in winter).

* The Link: There is no clear relationship between this demand and the demand for other products.

* Example: A finished car sitting on a dealership lot. The customer's decision to buy that car is independent demand.

2. Dependent Demand

This describes items that are only needed because they are parts of a larger finished product. The demand for these items is "derived" from the production plan of the final good.

* Materials involved: This includes raw materials, parts, and smaller assemblies.

* The Link: The amount needed is a direct mathematical function of how many finished products you plan to make.

* Example: If a car company decides to manufacture 100 cars, they "dependently" need 400 tires and 100 engines.

Summary Table

| Feature | Independent Demand | Dependent Demand |

|---|---|---|

| Source | Market/Customer | Production plans for a finished product |

| Stability | Fairly stable (with seasonal adjustments) | Fluctuates based on production schedules |

| Relationship | Not related to other products | Directly tied to the "parent" product |
