The Manufacturing Resource Planning (MRP II) System
The MRP II system comprises thematerials requirements planning
(MRP) system and the related systemsfor sales, billing, and purchasing.

Production Planning
Production planning involves thedetermination of which products
to produce and the schedulingof production to make optimaluse of production resources.

Activity-Based Costing
Traditional cost accounting techniquesmay be inadequate in a computer
integrated manufacturing environment.
Because CIM reduces directlabor and increases overhead.
Variable costs decreaseand fixed costs increase.
Activity-Based Costing
Activity-based costing (ABC) calculatesseveral overhead rates, one for
each manufacturing activity.
Activity-Based Costing
What are some examples of activities?
Machine centers Material handling
Inspection stations
A single department may containseveral different activities.
Manual assembly

Implementing JIT in aMRP II/CIM Environment
Less emphasis might be placedon a complete MRP II system.
