PAC - Production Activity Control
What must be done to keep priorities current?
react to changes in supply and demand
expedite, de-expedite, add, cancel, or change planned orders
Where do most MRP process inputs, outputs, and calculations occur?
Inside a computer through an MRP program.
What are 4 major data inputs to the MRP process?
Product structure file
Inventory record file
Item master file
What is an "item master file"?
It contains planning factors such as
Yield and scrap factors
A Planner does what 2 main things?
release the purchase orders to suppliers
release manufacturing orders, or shop orders, to the factory
What does planning software do?
plan for the release and receipt of priority plan
updates the priority plan
What are some calculations done by Planning Software?

The opposite of a BOM.
What are 4 uses of "where-used" reports?
identifying the parent items affected by an engineering change
assessing the aggregate impact of costing changes for a component
assessing the effects of component scarcity and setting allocations priorities
assessing the benefits and costs of standarizing similar components
What are 5 things shown in a Pegging report?
the parents creating demand for components
the quanities required
when those quantities are required
where-used logic to identify current sources of demand
may be single level or multilevel

What does a Planned Order become when it is released?
An open order.
What are some events affecting the priority plan?
Changes to customer orders
Late deliveries from supplier
Lower yields or higher scrap factors than planned
Late or early open order completions
Capacity or resource shortages
Material shortages casued by inventory record inaccuracies
