Modeling production policies

A new home for the Coupa Supply Chain documentation

Starting with Supply Chain 42, our documentation will be located on Coupa Compass. The help here will continue to be accessible for the foreseeable future, but will no longer be updated. If you need a Compass user account, contact your company’s Designated Support Contact (DSC).

You can access new and updated Supply Chain documentation in the following location on Compass:

Modeling production policies

Production Policies are used to define the production of products at specific sites.

Production policy elements

A site’s production policies include the following elements:

Site. The site that produces the product.
Product. The products that are generated by the production policy.
Production Policy. Method by which a production site is selected.
Production Time. The time required for production of the product.

Site Name	Product Name	Production Policy
MFG1	Product A	Make

Types of production policies

Production Policies are implemented based on the Production Policy selected:

Production Policy	Description
Make	Allows for production by filling incoming orders within the site. During the run, the required products are created at sites with this Production Policy to fulfill demand.
Make by Schedule	This Policy is unique in that it never places replenishment orders regardless of its inventory levels. It relies primarily on user designated production patterns in the Productions table to supply the model with products to fulfill demand. In Simulation, no productions for any amounts other than those in the Productions table occur for a Make by Schedule policy. For Optimization, only minimum production constraints are created. These do not act as fixed constraints. If fixed constraints are required, you should create them in the Production Constraints table. The Make by Schedule Production Policy is also used in conjunction with scripting logic implemented in Simulation scripts.

Allows for production by filling incoming orders within the site. During the run, the required products are created at sites with this Production Policy to fulfill demand.

Make by Schedule

In Simulation, no productions for any amounts other than those in the Productions table occur for a Make by Schedule policy. For Optimization, only minimum production constraints are created.
