5. Fixed Automation
• A system in which the sequence of processing (or assembly)
operations is fixed by the equipment configuration.
• Each of the operations in the sequence is usually simple,
involving perhaps a plain linear or rotational motion or an
uncomplicated combination of the two example, the feeding of a
rotating spindle.
• It is the integration and coordination of many such operations
into one piece of equipment that makes the system complex.

12. Material Handling
• Material handling is an important activity within larger system by
which material are moved, stored and tracked in our commercial
infrastructure.
• Handling of Materials must be performed safely, efficiently at low
cost, in a timely manner.
• The cost of material handling is a significant portion of total
production cost, estimates averaging around 20-25% of total
manufacturing labour cost in the United States .
19-09-2016 suryaprakash.s.eee@kct.ac.in 12
13. Continued.,
• Proportion varies, depending on the type of production and
degree of automation in the material handling function.

17. Automated Guided Vehicles
• Battery-powered, automatically steered vehicles that follow
defined pathways in the floor.
• Routing variations arc possible, meaning that different loads
move between different stations.
• They are usually interfaced with other systems to achieve the full
benefits of integrated automation
19-09-2016 suryaprakash.s.eee@kct.ac.in 17
18. Mono rail and other rail guided
vehicles:
• These are self-propelled vehicles that ride on a fixed rail system that
is either on the floor or suspended from the ceiling.
• usually driven by electric motors that pick up power from an
electrified rail.
• Like AGYs, routing variations are possible in rail-guided vehicle
systems
19-09-2016 suryaprakash.s.eee@kct.ac.in 18
19. Conveyors:
• Constitute a large family of material transport equipment that are
designed to move materials over fixed paths, generally in large
quantities or volumes.
• Examples include- roller, hilt, and tow-line conveyors. Conveyors can
be either powered or non-powered.
• Powered conveyors are distinguished from other types of powered
material transport equipment in that the mechanical drive system is
built into the fixed path.
• Non-powered conveyors are activated either by human workers or by
gravity.
19-09-2016 suryaprakash.s.eee@kct.ac.in 19
20. Cranes and hoists

21. 10 Principles of Material
Handling
• To provide
Safe Operating condition
Lower Cost
Better Utilization and Performance
• Unit Loading
• The unit load may consist of only one part, it may
consist of a container loaded with multiple parts, or
it may consist of a pallet loaded with multiple
containers of parts. In general, the unit load should
be designed to be as large as is practical for the
material handling system that will move or store it.
19-09-2016 suryaprakash.s.eee@kct.ac.in 21
22. Reason for Unit Loading:
1. Multiple items can be handled
simultaneously,
2. The required number of trips is reduced,
3. loading and unloading times are reduced,
and
4. product damage is decreased.
These reasons result in lower cost and
higher operating efficiency.

1. Continuous
2. Asynchronous
• Reasons for using asynchronous conveyors include:
1. to accumulate loads,
2. temporary storage,
3. to allow tor differences in production rates between adjacent processing
areas,
4. to smooth production when cycle times vary at stations along the
conveyor. and
5. to accommodate different conveyor speeds along the pathway
19-09-2016 suryaprakash.s.eee@kct.ac.in 28

32. Storage Systems
Sections:
1. Storage System Performance and Location
Strategies
2. Conventional Storage Methods and Equipment
3. Automated Storage Systems
4. Engineering Analysis of Storage Systems
33. Storage Systems
Function – to store materials (e.g., parts, work-in-
process, finished goods) for a period of time and
permit retrieval when required
• Used in factories, warehouses, distribution centers,
wholesale dealerships, and retail stores
• Important supply chain component
• Automation available to improve efficiency
34. Storage System Performance
Performance measures for storage systems:
• Storage capacity - two measures:
• Total volumetric space
• Total number of storage compartments (e.g., unit loads)
• Storage density - volumetric space available for
storage relative to total volumetric space in facility
• Accessibility - capability to access any item in storage
• System throughput - hourly rate of storage/retrieval
transactions
• Utilization and availability (reliability)
35. Storage Location Strategies
Two strategies: 1. Randomized, and 2. Dedicated
Randomized storage –
. Incoming items are stored in any available location
. Usually means nearest available open location
• Dedicated storage –
Incoming items are assigned to specific locations in the storage facility
• Typical bases for deciding locations:
• Items stored in item number sequence
• Items stored according to activity level
• Items stored according to activity-to-space ratios
37. Comparison of Storage
Strategies
• Less total space is required in a storage system that uses a randomized
storage strategy
• Dedicated storage requires space for maximum inventory level of each
item
• Higher throughput rates are achieved in a system that uses dedicated
storage strategy based on activity level
• The most active items can be located near the input/output point
• Compromise: Class-based dedicated storage
• Items divided into classes according to activity level
• Random storage strategy used within each class
38. Conventional Storage Methods
• Bulk storage - storage in an open floor area
• Problem: achieving proper balance between storage density and
accessibility
• Rack systems - structure with racks for pallet loads
• Permits vertical stacking of materials
• Shelving and bins - horizontal platforms in structural frame
• Steel shelving comes in standard sizes
• Finding items can be a problem
• Drawer storage - entire contents of each drawer can be viewed
39. Bulk Storage
Bulk storage arrangements:
(a) high-density bulk storage provides low accessibility,
(b) bulk storage with loads forming rows and blocks for improved
accessibility
40. Pallet Rack System
Pallet loads placed on racks in
multi-rack structure
(a) Low cost
(b) Good stroge density
(c) Good accessibility
41. Drawer Storage
• Contents easily visible
• Good accessibility
• Relatively high cost
Small items (tools, repair
parts, etc.)
42. Automated Storage Systems
Mechanized and automated storage equipment to reduce the human
resources required to operate a storage facility
• Significant investment
• Level of automation varies
• In mechanized systems, an operator participates in each
storage/retrieval transaction
• In highly automated systems, loads are entered or retrieved under
computer control
43. Objectives and Reasons for
Automating Storage Operations
• To increase storage capacity
• To increase storage density
• To recover factory floor space
currently used for WIP
• To improve security and reduce
pilferage
• To reduce labor cost and/or
increase productivity
• To improve safety

• To improve stock rotation
• To improve customer service
• To increase throughput
44. Types of Automated Storage
System
1. Automated Storage/Retrieval System (AS/RS)
• Rack system with mechanized or automated crane to
store/retrieve loads
2. Carousel Storage System
• Oval conveyor system with bins to contain individual items
46. AS/RS Types
• Unit load AS/RS - large automated system for pallet loads
• Deep-lane AS/RS - uses flow-through racks and fewer access aisles
• Mini load AS/RS - handles small loads contained in bins or drawers to
perform order picking
• Man-on-board AS/RS - human operator rides on the carriage to pick
individual items from storage
• Automated item retrieval system - picks individual items
• Vertical lift storage modules (VLSM) - uses a vertical aisle rather than a
horizontal aisle as in other AS/RS types
47. AS/RS Applications
1. Unit load storage and retrieval
• Warehousing and distribution operations
• AS/RS types: unit load, deep lane (food industry)
2. Order picking
• AS/RS types: miniload, man-on-board, item retrieval
3. Work-in-process storage

establishments
• Items are stored in bins suspended from the conveyor
• Lengths range between 3 m and 30 m
• Horizontal is most common type
• Vertical
• Operates around a vertical conveyor loop
• Less floor space required, but overhead room must be provided
50. Carousel Applications

the codes, and the equipment is more
expensive
• Two-dimensional symbologies divide into two
basic types:
(1) Stacked bar codes
(2) Matrix symbolizes.

• consists of multiple rows of conventional linear bar codes stacked
on top of each other.
• Different Schemes are available
• Encoded data in a stacked bar code are decoded using laser-type
scanners that read the lines sequentially.
• Problems encountered in reading a stacked bar code include:
(1) keeping track of the different rows during scanning,
(2) dealing with scanning swaths that cross between rows,
(3) detecting and correcting localized errors
