51. Type of Manufacturing in Oracle EBS R12?
Answer: In Oracle E-Business Suite (EBS) R12, there are several types of manufacturing supported to meet the diverse needs of different industries. The primary manufacturing types in Oracle EBS R12 include:
Discrete Manufacturing: This type of manufacturing is suitable for organizations that produce distinct, individual items or products. It involves the assembly of components or sub-assemblies into finished products. Discrete manufacturing is commonly used in industries like electronics, automotive, and consumer goods.
Process Manufacturing: Process manufacturing is designed for industries where products are made by mixing, blending, or chemical reactions rather than assembling discrete components. Industries such as pharmaceuticals, chemicals, and food and beverage often use process manufacturing.
Make-to-Order (MTO) Manufacturing: MTO manufacturing is used when products are only produced in response to specific customer orders. It involves creating a manufacturing order after receiving a customer order to ensure that products are tailored to customer requirements.
Make-to-Stock (MTS) Manufacturing: MTS manufacturing is used for producing products in anticipation of future demand. Finished products are manufactured and stocked in inventory based on forecasts or historical demand patterns.
Engineer-to-Order (ETO) Manufacturing: ETO manufacturing is applied when products are highly customized or engineered to meet specific customer requirements. Each product may have unique design specifications, and the manufacturing process is initiated after receiving an order.
Configure-to-Order (CTO) Manufacturing: CTO manufacturing is used for products with predefined options or configurations. Customers can select from a range of available configurations, and the product is assembled based on the customer's selections.
Project Manufacturing: Project manufacturing is employed when products are created as part of a larger project or contract. Manufacturing activities are associated with specific projects, and costs and resources are allocated accordingly.
Repetitive Manufacturing: Repetitive manufacturing is suitable for high-volume, repetitive production of standard products. It is often used in industries like automotive, where the same products are produced in large quantities with minimal variation.
Batch Manufacturing: Batch manufacturing involves the production of products in specific batch quantities. Each batch is typically associated with a unique batch number and may have slightly different characteristics.
Kanban Manufacturing: Kanban manufacturing is a just-in-time (JIT) manufacturing approach that relies on visual signals (kanban cards) to trigger the production of items as needed. It is commonly used in lean manufacturing environments.
Mixed-Mode Manufacturing: Mixed-mode manufacturing combines multiple manufacturing types within the same organization. It allows companies to handle various types of production processes based on their product portfolio and customer demands.
Discrete Manufacturing and Process Manufacturing are two distinct manufacturing methods, each suited for different types of products and industries. Here are the key differences between Discrete Manufacturing and Process Manufacturing:
1. Product Type:
Discrete Manufacturing: In discrete manufacturing, products are typically individual, distinct items that can be counted and identified separately. These products are often assembled from various components or parts. Examples include electronics, automobiles, and appliances.
Process Manufacturing: Process manufacturing is used for products that are produced by mixing, blending, or chemical reactions. The final product is often a combination of ingredients that cannot be easily separated or counted individually. Examples include chemicals, pharmaceuticals, food and beverages, and paints.
2. Bill of Materials (BOM):
Discrete Manufacturing: Discrete manufacturing uses a Bill of Materials (BOM) that specifies the list of components and their quantities required to assemble a finished product. Each finished product has a unique BOM, and components are combined during the assembly process.
Process Manufacturing: Process manufacturing uses a formula or recipe that specifies the ingredients, their proportions, and the production process. The same formula or recipe is applied to produce multiple batches of the same product.
3. Production Process:
Discrete Manufacturing: Discrete manufacturing involves the assembly of components or parts in a specific order to create finished products. Assembly lines and workstations are common in discrete manufacturing.
Process Manufacturing: Process manufacturing involves continuous or batch processing. Ingredients are mixed or processed in tanks, vessels, or reactors, and the final product is often the result of chemical reactions or physical changes.
4. Customization:
Discrete Manufacturing: Discrete manufacturing allows for a higher degree of product customization. Products can be configured with different options or features based on customer requirements.
Process Manufacturing: Process manufacturing is less conducive to customization. Products are typically produced according to a standard formula or recipe, and variations are limited.
5. Inventory Tracking:
Discrete Manufacturing: Inventory in discrete manufacturing is tracked in terms of individual components and finished products. Each component has a unique identity, and inventory can be counted easily.
Process Manufacturing: Inventory in process manufacturing is tracked in terms of bulk quantities of ingredients or materials. It may be measured in weight or volume, and individual units are not easily distinguishable.
6. Quality Control:
Discrete Manufacturing: Quality control in discrete manufacturing often involves inspection of individual components and finished products at various stages of assembly. Defective parts can be replaced or reworked.
Process Manufacturing: Quality control in process manufacturing focuses on ensuring the correct formulation and adherence to process parameters. It involves monitoring the quality of ingredients and the consistency of the production process.
7. Industries:
Discrete Manufacturing: Common industries that use discrete manufacturing include automotive, electronics, aerospace, and consumer goods.
Process Manufacturing: Common industries that use process manufacturing include chemicals, pharmaceuticals, food and beverages, and cosmetics.
8. Production Planning:
Discrete Manufacturing: Discrete manufacturing often involves production planning based on demand forecasts, customer orders, and make-to-stock or make-to-order strategies.
Process Manufacturing: Process manufacturing typically involves production planning based on production schedules, batch sizes, and the availability of raw materials.
9. Regulatory Compliance:
Discrete Manufacturing: Regulatory compliance may be related to product safety and quality standards.
Process Manufacturing: Regulatory compliance is often more stringent, particularly in industries like pharmaceuticals and food, where product consistency and safety are critical.
