Overview

The scenario describes the production process following the make-to-stock 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 production is done in several stages with 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.
