Material Requirements Planning
ERP -
MRP-
a computer system that integrates application programs in accounting, sales, manufacturing, and the other functions in a firm
a means for determining the number of parts, components, and materials needed to produce a product
9.15
Dependent demand is drives the (ERP/MRP) system?
MRP
9.19
ERP or MRP?
The logic that ties production functions together from a material planning and control view.
A logical, easily understood approach to the problem of managing the parts, components, and materials needed to produce end items
MRP
9.19
The ___ deals with end items and is a major input to the MRP process
master schedule
9.20
The ___ provides the general range of operation, the ___ must specify exactly what is to be produced
aggregate plan
master scheduler
9.20
To determine an acceptable feasible schedule to be released to the shop, trial master production schedules are tested using the (ERP/MRP) program
MRP
9.20
What is: contains the complete product description, listing the materials, parts, and components along with the sequence in which the product is created
