• Part offirms logistics system that stores products at and between point
of origin and point of consumption.
• Term “Warehousing” is referred as transportation at zero miles per
hour
• Warehousing provides time and place utility for raw materials,
industrial goods, and finished products, allowing firms to use customer
service as a dynamic value-adding competitive tool.
3.
THE ROLE OFTHE WAREHOUSE IN THE LOGISTICS SYSTEM
• The warehouse is where the supply chain holds or stores goods.
• Functions of warehousing include
– Transportation consolidation
– Product mixing
– Docking
– Service
– Protection against contingencies
4.
TYPE OF WAREHOUSING
•Public Warehousing
• Private Warehousing
• Contract Warehousing
• Multi-client Warehousing
OBJECTIVES OF EFFICIENTWAREHOUSE OPERATIONS
• Provide timely customer service.
• Keep track of items so they can be found readily & correctly.
• Minimize the total physical effort & thus the cost of moving goods into &
out of storage.
• Provide communication links with customers
9.
• Benefits ofWarehouse Management
– Provide a place to store & protect inventory
– Reduce transportation costs
– Improve customer service levels
• Complexity of warehouse operation depends on the number of SKUs handled
& the number of orders received & filled.
• Most activity in a warehouse is material handling.
10.
• Capital costs
—Costsof space & materials handling equipment
• Operating costs
—Cost of labor
—Measure of labor productivity is the number of units that an operator
can move in a day
COSTS OF OPERATING A WAREHOUSE
11.
WAREHOUSE ACTIVITIES
• Receivegoods
• Identify the goods
• Dispatch goods to storage
• Hold goods
• Pick goods
• Marshal shipment
• Dispatch shipment
• Operate an information system
12.
• Accepts goodsfrom
‒ Outside transportation or attached factory & accepts responsibility
• Check the goods against an order & the bill of loading
• Check the quantities
• Check for damage & fill out damage reports if necessary
• Inspect goods if required
Receive goods
13.
‒ items areidentified with the appropriate stock-keeping unit (SKU)
number (part number) & the quantity received recorded
Identify the goods
Dispatch goods to storage
‒ goods are sorted & put away
Hold goods
‒ goods are kept in storage & under proper protection until needed
14.
Pick goods
‒ itemsrequired from stock must be selected from storage & brought to
a marshalling area
Marshal the shipment
‒ goods making up a single order are brought together & checked for
omissions or errors; order records are updated
15.
Dispatch the shipment
‒orders are packaged, shipping documents are prepared, & goods
loaded on the vehicle
Operate an information system
‒ a record must be maintained for each item in stock showing the
quantity on hand, quantity received, quantity issued, & location in the
warehouse
16.
Maximize productivity &minimize cost, warehouse
management must work with the following
• Maximize use of space
– space is the largest capital cost
• Effective use of labor & equipment
– labor is the largest operating cost
– material handling equipment is the second largest capital cost
17.
FACTORS INFLUENCING EFFECTIVEUSE OF WAREHOUSES
• Cube utilization and accessibility
• Stock location
• Order picking and assembly
• Physical Control & Security - Elements
18.
Cube utilization andaccessibility
‒ Goods stored not just on the floor, but in the cubic space of the
warehouse; warehouse capacity depends on how high goods can be
stored
‒ Accessibility means being able to get at the goods wanted with a
minimum amount of work
Stock Location
• Objectives
–To provide the required customer service
– To keep track of where items are stored
– To minimize effort to receive, put away, and retrieve items
• Basic Stock Locating Systems
– Group functionally related items together
– Group fast-moving items together
– Group physically similar items together
– Locate working stock and reserve stock separately
21.
• Fixed Location
–SKU assigned a permanent location, & no other items are stored there
– Fixed-location systems usually have poor cube utilization
– Usually used in small warehouses; throughput is small, & there are few SKUs
• Floating (Random) Location
– Goods stored wherever there is appropriate space
– Advantage is improved cube utilization
– It requires accurate and up-to-date information
– Warehouses using floating-location systems are usually computer-based
Stock Location continued…
22.
Stock Location continued…
•Two other systems sometimes used are
– Point-of-use storage
• Inventory stored close to where it will be needed
• Used in repetitive manufacturing & JIT systems
– Central storage
• Contains all inventory in one central location
23.
• Advantages ofPoint-of-use Storage
– Materials are readily accessible to users
– Material handling is reduced or eliminated
– Central storage costs are reduced
– Material is accessible all the time
Stock Location continued…
24.
• Advantages ofCentral Storage
– Ease of control
– Inventory record accuracy is easier to maintain
– Specialized storage can be used
– Reduced safety stock, since users do not need to carry their own
safety stock
Stock Location continued…
25.
Order Picking andAssembly
• When an order is received, items must be obtained from the
warehouse, grouped, & prepared for shipment, systems used
– Area system
– Zone system
– Multi-order system
26.
• Area system
–Order picker circulates throughout warehouse selecting items on an
order -- order is ready to ship when order picker is finished
• Zone system
– Warehouse is divided into zones, & each picker works only in an
assigned zone -- order is divided by zone, & the items from each
zone are sent to the marshaling area
Order Picking and Assembly continued…
27.
• Multi-order system
–Same as the zone system, except that each picker collects
items for a number of orders at the same time
Order Picking and Assembly continued…
28.
PHYSICAL CONTROL &SECURITY - ELEMENTS
• Good part numbering system
• Simple, well-documented transaction system
– Identify the item
– Verify the quantity
– Record the transaction
– Physically execute the transaction
• Limited access
– Inventory must be kept in a safe, secure (locked) place with limited
general access
• Well-trained workforce
