Production Systems Flashcards
Production system
A collection of people, equipment, procedures organized to accomplish the manufacturing operations of a company
Manufacturing support systems
Set of procedures, including: Manage production, Order materials, Transport materials, ensure quality standards, design products.
Production facilities
factory equipment, and the way the equipment is organized, Plant layout
Plant layout
The way equipment is arranged
Manufacturing systems
Equipment organized into logical groupings
Q
Production Quantity
What letter represents Production Quantity?
Q
Why is Production quantity important
It influences the way a companies people, facilities and procedures are organized
P
Product variety
What does product variety mean?
Product variety means: Different products- different shapes, sizes and styles; intended for different markets; have more parts than others.
relationship between no. product types and variety
Large number of product types = High product variaty
Correlation between Variety (P) and quantity (Q)
there is an inverse correlation between product variety P, and product quantity Q. If factories P is high, then Q is likely to be low.
Why is P much less exact than Q
Differences in design details does not = no. different designs.
Soft product variety
Small difference in products. E.G. car models made on the same production have a high prop
Hard product variety
Products differ substantially, few, if any common parts
what is a Job shop
A job shop is a low quantity Production facility with:
-Low quantity range (0-100 units/year)
-Specialized and custom products
-Complex products
-general purpose equiptment
-highly skilled labour
-maximum flexibility
Fixed position layout
This type of factory is used for craft based industry and very large products like: Ships, aircrafts, heavy machinery, specialist car manufacture.
Process layout (Functional layout)
used for jobbing manufacture and batch manufacture. Q = 1 to 000’s.
-Most versatile type of manufacture.
-Suits frequently changing product mix
-Typical of factories manufacturing machined metal components
(E.G. all milling in one area)
Low production range
0-100 Annual Units
Medium production range
100-10,000 Annual Units
High production range
10,000 to millions
Facility: Hard product variety
Batch production
-Set-up time = lost production
-usually arranged in a process layout
Facility: Soft product variety
Cellular manufacturing
-Changeover time minimal
-Cellular layout based on Group Technology
Quantity production
single parts on single pieces of equipment
process layout
Flow line produciton
Parts and assemblies move through multiple workstations. Product layout. Used for very high volume or mass production. Cars
