The scenario describes the production process following the make-to-stock production model describes the manufacturing of large quantities of standardized products, which are then placed on stock and subsequently sold to customers. Typically, the make-to-stock production model is used when there are a few product lines and long costly changeover times between products. The make-to-stock scheduling objective ensures constant equipment utilization and allows optimization of lot sizes, which leads to a maximization of output. The production processes deployed in discrete manufacturing are not continuous in nature. Each process can be individually started or stopped and can be run at varying production rates. Products in discrete manufacturing industries require often to perform many production steps in an order distinct to the specific product. Sometimes combined with quite complex structures of a product-specific bill of material, defining which components and materials are required to assemble the final product. model, where products can be and usually made before a sales order confirmation. Sales orders are typically supplied from existing stock, and production orders are used to replenish those stocks. The scenario starts with the creation of plan-based production orders for large quantities of standardized products and ends with a production of all quantities of the product required by the plan. The scenario is applied for discrete manufacturing and can't be applied for continuous manufacturing. Each production stage can be individually started, postponed, the lot can be changed at any moment of production. Discrete manufacturing requires a multistage production process with numerous interdependent steps to make a specific product. As the product structure is complex, it requires a complex bill of materials, routing, and operations with defined materials. The Very likely, the production is done in several stages with intermediates, for which individual production orders are generated. In some industries such as automotive, the hierarchical structure of a product's bill of material can be as deep as 23 levels with intermediate products on each level. Those are rarely produced with on enterprise but rather in a highly complex supply chain of many levels of suppliers contributing to the final product. In this scenario, material requirements planning (MRP) is applied, which only evaluates material requirements. The actual resolving of possible capacity or resource constraints takes place in a manual monitoring process. a lot of intermediate products which are used in other intermediate or finished products. Very likely, the make-to-order/assemble-to-order and make-to-stock scenarios can be combined. Intermediate products are made in stock, while finished products are made on customer's orders. The scheduling focuses on maximizing the output by maximized machine use and optimization of production lot sizes.
