Overview

JD Edwards EnterpriseOne Repetitive Manufacturing is designed for items produced in a continuous process on a dedicated production line.

Repetitive manufacturing is typically characterized by these conditions:

  • Production lines are dedicated to a family of products.
  • Product families share similar components and routing instructions.
  • Products are often manufactured in a continuous process that requires less inventory movement to and from the production line.
  • Work center setup and changeover times between related products are minimized.
  • Production is defined in units per hour.  The time spent at the operational level might or might not be important.  Therefore, the ability is needed to set up line capacity and define routing instructions in units per hour.  The fundamental basis for back scheduling and capacity planning is hours. To view information in units, a conversion factor is defined at the work center level.
  • Visual cues, called kanbans, control material movement.  Kanbans represent predetermined quantities of components at specified locations on the production line.  They are designed to minimize work-in-process inventories.

Repetitive or rate-based manufacturing of discrete products uses manufacturing techniques that are associated with achieving just-in-time or flow line production.  Repetitive manufacturing aims to achieve the continuous production of a mix of similar items on a specialized flow line rather than the traditional work order with its fixed quantity and due date of a single item.  It is usually the preferred method with families of products that have minor variations among products with a constant and high-volume demand.

 

A rate schedule is a request to complete a certain quantity of an item over a period of time on a specific production line.  Rate schedules consist of headers, parts lists, and routing instructions.  The rate schedule header specifies the quantity of the item being manufactured, the required completion date, and the production line.  The parts lists and routings specify the components, operations and resources required to complete rates.

The Production Line is a sequence of operations that are arranged to produce a family of products.  The production line is defined as a work center.  The operations that make up the production line might or might not be work centers.  This is defined in the routing instruction.  The capacity of the production line is determined by the constraining operation within the production line.

The Bill of Material for items produced in a repetitive manufacturing environment determines the operation sequence numbers that are crucial to ensure that the components are delivered to the production line at the operations for which they are needed.  Because the line is setup to run in a continuous fashion, components typically are setup to be consumed through backflushing, at a specific paypoint, or upon completion.

 

The Routing Instruction represents the relationship between the production line and the operations or work centers that the line contains for the parent item.

Each operation is tied to its production line by the line or cell number in the Line/Cell field on the routing instruction.
