Manufacturing forms a key part of the Supply Chain Management process. The
basic cycle is that customer orders and forecasted demand are combined to
form a Master Production Schedule. Material Requirements Planning (MRP) uses
the Master Production Schedule and Bill of Materials to create requirements
for parts at all levels -- purchased parts, assemblies and final products. To
fulfill this demand, MRP sends purchase requisitions to Purchasing based on
the lead times in Inventory and creates work orders for the fabrication of
assemblies. GNU Enterprise Manufacturing supports different styles of
manufacturing - engineer-to-order, repetitive and process.
A Bill of Materials (BOM) describes how to make an Inventory item. That
includes both the materials and the operations which are necessary to build
the item. The operations include both the resources required and the time
for setup, produce and clean up. For ease of use, GNU Enterprise
Manufacturing allows Bills of Materials to be constructed using 'drag and
drop' technology. It also provides 'WHERE USED' queries for Inventory item
A manufacturing facility has only so much capacity to produce goods.
Capacity Requirements Planning (CRP) reviews the detailed production
schedules proposed by MRP. Based on the operations information in Bill of
Materials, it locates periods where the schedule exceeds the capacity of the
manufacturing facility. Users use an iterative approach to find a solution
which fits both MRP and CRP.
Both Engineering and Bill of Materials work on the BOM tables. Bill of
Materials -- emphasis is on production. Engineering's emphasis is on
development. Engineering creates new BOMs and modifies existing BOMs via
Engineering Change Orders which usually have an effective date.
The Master Product Schedule represents the company's high-level decisions
about what is to be produced. It is based on customer orders and forecasted
demand over a planning interval (often several months). The Master
Production Schedule is used to drive the rest of the Manufacturing package.
It is a small table but a very important one.

Work in Process (or MRP) issues Work Orders to make a specified number of an
item, collects actual time (as opposed to standard time contained on the
Bill of Materials) and reports the progress of the Work Order through its
various steps. If there are variances in material or labor, Cost Management
reports it so errors can be corrected and realistic standards maintained.
In some types of manufacturing, the runs are very long so the setup time is
not relevant. An assembly line is an example of this type of repetitive
manufacturing. The Repetitive Manufacturing sub-system adapts the basic
Manufacturing package to this specialized environment.
Process Manufacturing deals with continuous rather than discrete processes.
An oil refinery is an example of process manufacturing. The Process
Manufacturing sub-system adapts the basic Manufacturing package to this
After you sell a product to a customer, you usually must service it. GNU
supports you in this by scheduling both on-site and depot service,
monitoring service delivery, managing warranties and handling service
Delivering a quality product gives your company a critical competitive edge.
GNU Enterprise Quality helps you define quality standards, manages the
physical testing of items, issues Quality Alerts if the standards are not
adhered to. With GNU Enterprise Quality, you are a long step forward towards
ISO 9000 certification.
