Question
**Material Requirements Planning (MRP) Overview**

**Objective:**
Develop a material requirements plan for end item **P** and its components, using the provided tree diagram.

**Assumptions:**
- All lead times are one week.
- Lot-for-lot ordering is used except for item **F**, which is ordered in multiples of 400 units.

**Requirements:**
- One hundred units of **P** must be available at the start of week 4 and week 8.

**Beginning Inventories:**
- **P**: 20 units
- **A**: 100 units
- **F**: 200 units

**Scheduled Receipts:**
- 800 units of **F** at the start of week 1.

**Product Structure Tree Diagram:**

- **P**
  - **A** (2)
    - **D** (4)
    - **F** (2)
  - **B** (3)
    - **D**
    - **F** (2)
  - **C** (2)

**Explanation of Diagram:**
- **P** is the end product.
- **A**, **B**, and **C** are components used to produce **P**.
  - Each **P** requires 2 units of **A**, 3 units of **B**, and 2 units of **C**.
- **A** requires:
  - 4 units of **D**.
  - 2 units of **F**.
- **B** requires:
  - **D** and 2 units of **F**.

This structure indicates the hierarchical requirement of components for assembling product **P**, with specifications on the quantity of each component needed at different levels of the assembly.
