The following techniques are commonly used to create and manage Bill of Materials (BOMs):

1. Engineering Change Order (ECO): An ECO is used to update the BOM when changes are made to the design of the product. It is important to keep the BOM up-to-date to ensure that the correct parts are ordered and that production runs smoothly.
2. Modular BOM: A modular BOM is used when a product is made up of interchangeable modules. Each module has its own BOM, which can be used to build a customized product.
3. Phantom BOM: A phantom BOM is used when a sub-assembly is made up of other sub-assemblies. It is important to track the components of each sub-assembly to ensure that the correct parts are ordered.
4. Indented BOM: An indented BOM is used to show the hierarchical relationship between different levels of the BOM. This is useful for complex products that are made up of many sub-assemblies.
5. Single-level BOM: A single-level BOM is used for products that are simple and made up of only one or a few parts.
6. Modular product design: In a modular product design, products are designed to be made up of interchangeable modules that can be used in different products. This approach simplifies the BOM and makes it easier to manage.

Overall, the goal of these techniques is to create a BOM that accurately reflects the components of the finished product and makes it easy to manage the production process. By carefully managing the BOM, businesses can reduce errors and avoid costly delays in production.

The techniques used in Material Requirements Planning (MRP) include the following:

1. Bill of Materials (BOM): A bill of materials is a list of all the raw materials, components, and sub-assemblies needed to manufacture a finished product. The BOM is used to calculate the material requirements for each product, based on the production plan and the inventory schedule.
2. Master Production Schedule (MPS): A master production schedule is a detailed plan that specifies the quantity of each product that needs to be produced during a specified time period. The MPS is used to calculate the materials requirements for each product, based on the production schedule and the inventory levels.
3. Inventory Status File: The inventory status file contains information about the current inventory levels of raw materials, components, and finished products. It is used to calculate the materials requirements for each product, based on the production plan and the inventory levels.
4. Materials Requirements Planning (MRP) Software: MRP software is a computerized tool that is used to automate the materials planning process. It takes into account the BOM, the MPS, and the inventory status file, and calculates the materials requirements for each product, based on the production plan and the inventory levels. It generates purchase orders or manufacturing orders for the required materials, based on lead times and other constraints.

Overall, the key technique in MRP is the use of computerized software to automate the materials planning process. This helps businesses to plan and manage their materials more efficiently, and to optimize their production processes.
