Introduction Importance of layout Need of layout Types of layout
Product Layout Process Layout Fixed Position Layout Cellular Layout Mixed Layout
Introduction 3
Deals with the physical
arrangement of various resources that are available in the system with an objective to improve the performance of the operating system thereby providing better customer service
The Need for Layout Decisions 4
Inefficient operations For Example:
High Cost Bottlenecks
Changes in the design of products or services
Accidents The introduction of new products or services
Safety hazards
(Cont’d) 55
Changes in environmental or other legal requirements
Changes in volume of output
Morale problems Changes in methods and equipment
Importance 6
i. Requires substantial investments of money and efforts ii. iii.Involves long term commitments iv. v.Significant impact on cost and efficiency of operations vi. vii.
Problems if Layout is improper 7
Idle time increases Higher cost Inefficiency increases Accidents may occur
Types of Layouts 8
Types of facilities layout :1.Product layout 2.Process layout 3.Fixed position layout 4.Cellular layout 5.Mixed Layout
Product Layout 9
Achieve smooth, rapid & high volume flow Layout should be straight, U or S shape Division of work Machines are dedicated for single task Workstations should be located closely Speed is determine with workstation having lowest
capacity
Example of straight line 10
CUTTING
SANDING
PAINTING
PRODUCT
U & S Shape 11
Half the length of straight production line More compact Flexibility in work and workers Minimizes material handling
Example of S shape 12
STARTS PRODUCTIO N
CRUSHIN G
HOMOGINISATIO N PACKAGING MACHINE
BOILING
FILTRATION FINISHED PRODUCTION
Advantages 13
Mass production is possible Low unit cost High utilization of cost and labor Scheduling is not necessary after design Standardized products are obtained Less multi-skilled labors are required
Disadvantages 14
System is inflexible Because of repetitive job it provides little opportunity
for development Worker losses morale Poorly skilled labor can’t maintain equipment or quality of product
Process Layout 15
Based on functions equipments are placed together Intermittent process Use flexible equipments and workers Variety of jobs can be performed It includes Job shop and Batch process
Functional Approach 16
Function A
Function B
Function C
Function D
Function E
Function F
Work travels to dedicated process centers 17
Milling Assembly & Test
Drilling
Grinding
Plating
Examples 18
Car servicing Hospitals – Patients requiring various test Universities and colleges Airlines
Car Servicing 19
Washing
Servicing
Oiling
Repairing
Painting
Advantages 20
Reduced cost as general purpose machines are used Greater flexibility Less maintenance cost Investment is less Greater scope of expansion as the capacities on
different lines can be increased Easy to handle breakdown of equipment
Disadvantages 21
Process inventory cost can be high With more numbers of operations flow becomes
complex and difficult to manage Routing and scheduling should be done on a continual basis Equipments utilizations rates are low Material handling is slow and inefficient More costly per unit as compared to product layout
Fixed –Position Layout 22
Product remains stationary, resources travel to
product or customer. Mostly for bulky and very large product. Limited space required.
Examples 23
In bulky product - ship ,building, rocket…. In small size product – battery production…. In service product – operation theater in
Hospital , movie making…
Advantages 24
Minimum product movement. Promote job enlargement Continuity of operation Higher flexibility
Disadvantage 25
Increased movement of personnel & equipments. Higher skilled personnel required Low utilization of equipment. Greater coordination required
Cellular Layout 26
This is philosophy that seeks to exploit the
commonality in manufacturing and uses this as a basis for grouping components and resources. This is also known as cellular manufacturing. Pioneered by Russians Mid volume & mid variety scenario 70% of mfg. industry may fall under this category)
Cellular Layout- Examples 27
Reliance industries- HDPE & LDPE Titan Industry ABB( Industrial fans & blowers)
Advantages of Cellular Layout 28
PPC becomes simpler Material handling becomes easier Traceability improves Employees are able to relate better. Helps in implementing SGA, Kaizen an JIT
DISADVANTAGES
Reduced manufacturing flexibility & potentially
increased machine- down time ( since machines are contained to cells & may not be used all the time) & finally duplicate pieces of equipment may be needed so that parts need not be transported between cells.
Mixed Layout 30
Two or more layout types in single facility
Eg :- Hospital Restaurant
