Warehousing Operations
• Storing or warehousing, is a major part ofdistribution management.
• Planned space for the storage and handlingof goods and material.

THE ROLE OF THE WAREHOUSE INTHE LOGISTICS SYSTEM
• The warehouse is where the supplychain holds or stores goods.• Functions of warehousing include
Transportation consolidationProduct mixingDockingServiceProtection against contingencies
![Page 5: Management 106](https://reader033.fdocuments.us/reader033/viewer/2022061603/55533e97b4c905e12e8b5419/html5/thumbnails/5.jpg)
Functions of Warehouse
• Transportation consolidationFrom figure 1.1, warehouse consolidate
all incoming goods from different suppliers‘Less than Truck-load(LTL) and ship a FullTruck load (FTL) to a plant.
![Page 6: Management 106](https://reader033.fdocuments.us/reader033/viewer/2022061603/55533e97b4c905e12e8b5419/html5/thumbnails/6.jpg)
Functions of Warehouse
• Product mix - In a typical mixing operation, truck loadsof products are shipped from origin to the mixingwarehouse.
• Docking - is a practice in which materials areunloaded from an incoming semi-trailer truck orrailcars, with little or no storage in between
• Service - Warehouses can provide services thatenhance a firm's revenue growth.
• Protection against contingencies - Warehousingexists such as transportation delays, vendor stockouts, or strikes.

Some valid reasons for holding stockinclude the following.
• As a buffer/consolidation point between twoproduction processes
• suppliers' lead-time• To enable savings to be made through bulkpurchases or discounts
To cope with seasonal fluctuationsTo provide a variety of product in acentralized locationThe build up/holding of anticipation stocks(for example, before a new product launch)The build-up and holding of investment stocks

Purpose of a Warehouse
• Primary aim for a warehouses anddistribution centers is to facilitate the movementof goods from our suppliers to customers and,by doing so, meet customers' demand in atimely and cost-effective manner.
• The purpose of warehouse management hasexpanded. The days of a warehouse just“housing” goods and supplies are long gone.
• Basic aim must be to minimize the total costof the operation while providing the desiredlevel of service.

Types of warehouses
There are two basic types of warehouses:private and public. Facilities can be furtherdivided according to use as storage warehousesor distribution centers.
1. Private 2. Public
![Page 10: Management 106](https://reader033.fdocuments.us/reader033/viewer/2022061603/55533e97b4c905e12e8b5419/html5/thumbnails/10.jpg)
Private warehousesare owned by a single manufacturer,
wholesaler or retailer. Most are run by largefirms with continuous storage needs for massquantities.
Public warehousesare independently owned by operated.
They are also used by manufacturers who needmultiple storage locations to get products tomultiple markets.
![Page 11: Management 106](https://reader033.fdocuments.us/reader033/viewer/2022061603/55533e97b4c905e12e8b5419/html5/thumbnails/11.jpg)
Warehouse Policies & Procedures
Running a warehouse business can bechallenging. To be successful, you will need to setclear guidelines and expectations.
Put Safety FirstSafety should be your primary concern,
and it is vital that every member of the staffunderstands the importance of established safetyprocedures.
Equipment InstructionsMost working warehouses use many
different types of equipment such as pallet jacks,forklifts, presses and stackers. Although onlytrained operators should use that equipment,not every worker will have the same level oftraining and experience
![Page 12: Management 106](https://reader033.fdocuments.us/reader033/viewer/2022061603/55533e97b4c905e12e8b5419/html5/thumbnails/12.jpg)
Storage Warehousesprovide storage for extended periods.
Procedures of seasonal items, such agriculturalcorps, use this type of warehouse.
Distribution Centersprovide short-term storage of products
whose demand is both constant and high.Distribution centers are common in the groceryand food industry.
![Page 13: Management 106](https://reader033.fdocuments.us/reader033/viewer/2022061603/55533e97b4c905e12e8b5419/html5/thumbnails/13.jpg)
Warehouse Policies & Procedures
Post Hours and Rules - Signage is an important part of any
warehouse, and it is important that managementpost signs in conspicuous locations.
- Large signs should be used to communicateimportant information such as emergencyprocedures, worker expectations and hours ofoperation.

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 costof moving goods into & out of storage.• Provide communication links with customers
![Page 21: Management 106](https://reader033.fdocuments.us/reader033/viewer/2022061603/55533e97b4c905e12e8b5419/html5/thumbnails/21.jpg)
Benefits of Warehouse ManagementProvide a place to store & protect inventoryReduce transportation costsImprove customer service levelsComplexity of warehouse operation
depends on the number of SKUs handled &
the number of orders received & filled.Most activity in a warehouse is material handling.
Increase Employee Efficiency & Productivity
Real-time data management enables you to viewthe exact levels of your inventory
Online access to information
![Page 22: Management 106](https://reader033.fdocuments.us/reader033/viewer/2022061603/55533e97b4c905e12e8b5419/html5/thumbnails/22.jpg)
COSTS OF OPERATING A WAREHOUSE
• Capital costs— Costs of space & materials handling equipment— Clerical costs of producing reports will be reducedbecause up-to-date information already exists in thedatabase and there are predefined reports. As well,receiving discrepancies and inventory adjustments will be reduced by using handheld computers and barcodes.
• Operating costs— Cost of labor— Measure of labor productivity is the number of unitsthat an operator can move in a day
![Page 23: Management 106](https://reader033.fdocuments.us/reader033/viewer/2022061603/55533e97b4c905e12e8b5419/html5/thumbnails/23.jpg)

Warehouse Effectiveness
• Cube utilization and accessibility• Stock location• Order picking and assembly• Packaging
![Page 35: Management 106](https://reader033.fdocuments.us/reader033/viewer/2022061603/55533e97b4c905e12e8b5419/html5/thumbnails/35.jpg)
Cube utilization and accessibility
‒ 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
‒ Space also required for:aisles officesreceiving order pickingshipping docks order assembly
![Page 36: Management 106](https://reader033.fdocuments.us/reader033/viewer/2022061603/55533e97b4c905e12e8b5419/html5/thumbnails/36.jpg)

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
![Page 38: Management 106](https://reader033.fdocuments.us/reader033/viewer/2022061603/55533e97b4c905e12e8b5419/html5/thumbnails/38.jpg)
Stock Location
Fixed Location• SKU assigned a permanent location.• Fixed-location systems usually have poor cube utilization• Usually used in small warehouses; throughput is small, & thereare 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
![Page 39: Management 106](https://reader033.fdocuments.us/reader033/viewer/2022061603/55533e97b4c905e12e8b5419/html5/thumbnails/39.jpg)

Order Picking and Assembly
• When an order is received, items must be
obtained from the warehouse, grouped, &
prepared for shipment, systems used
– Area system - Used in small warehouses
– Zone system
– Multi-order system
![Page 42: Management 106](https://reader033.fdocuments.us/reader033/viewer/2022061603/55533e97b4c905e12e8b5419/html5/thumbnails/42.jpg)
Area System
• Used in small warehouses • Order picker circulates throughout warehouseselecting items on an order• The order picker moves through the warehouseand takes all the goods to shipping
self marshallingorder is complete when the picker is finished
![Page 43: Management 106](https://reader033.fdocuments.us/reader033/viewer/2022061603/55533e97b4c905e12e8b5419/html5/thumbnails/43.jpg)
Zone System
• Warehouse is divided into zones
• Order pickers work in their own area
deliver goods to the marshalling area
• Zones are established by related items
type of storage
type of material handling required
• Marshalling area then organizes orders for
shipment
![Page 44: Management 106](https://reader033.fdocuments.us/reader033/viewer/2022061603/55533e97b4c905e12e8b5419/html5/thumbnails/44.jpg)
Multi-order System
• Similar to zone system
• Multiple orders are picked together
• Marshalling area then sorts orders by
shipment
• Used where there are many items or many
small orders
![Page 45: Management 106](https://reader033.fdocuments.us/reader033/viewer/2022061603/55533e97b4c905e12e8b5419/html5/thumbnails/45.jpg)
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
![Page 46: Management 106](https://reader033.fdocuments.us/reader033/viewer/2022061603/55533e97b4c905e12e8b5419/html5/thumbnails/46.jpg)
What Is Packaging?
• Consumer packagingMarketing managers primarily concerned withhow the package fits into the marketing mix.
• Industrial packagingLogistics managers primarily concerned withefficient shipping characteristics includingprotection, ability to withstand stacking whenon a pallet, cube, weight, shape and otherrelevant factors.

Inventory
• Inventory is an idle stock of physical goodsthat contain economic value, and are held invarious forms by an organization in its custodyawaiting packing, processing, transformation,use or sale in a future point of time.
From the above definition the following pointsstand out with reference to inventory:• All organizations engaged in production. • Inventory can be in complete state or incompletestate.• Inventory is held to facilitate future consumption. • All inventoried resources have economic valueand can be considered as assets of the organization.
![Page 51: Management 106](https://reader033.fdocuments.us/reader033/viewer/2022061603/55533e97b4c905e12e8b5419/html5/thumbnails/51.jpg)
Managing Inventory Levels
It has been established that the role of inventorymanagement is to ensure that stock is available tomeet the needs of the beneficiaries as and whenrequired.
This is made up of the cost of the inventory itself, plusthe cost of transporting the goods, cost of managingthe goods.
In order to achieve this, the inventory manager mustensure a balance between supply and demand byestablishing minimum holding stocks to coverlead-times
![Page 52: Management 106](https://reader033.fdocuments.us/reader033/viewer/2022061603/55533e97b4c905e12e8b5419/html5/thumbnails/52.jpg)
Types of Inventories
Raw materials & purchased parts - are inventory
items that are used in the manufacturer's conversion
process to produce components, subassemblies, or
finished products.
Partially completed goods called work in progress - (WIP) is made up of all thematerials, parts (components), assemblies, andsubassemblies that are being processed or arewaiting to be processed within the system.
Finished-goods inventories
(manufacturing firms) or merchandise (retail stores)

Types of Inventories
Goods-in-transit to warehouses or customers Transit
inventories result from the need to transport items or
material from one location to another, and from the
fact that there is some transportation time involved in
getting from one location to another.
![Page 54: Management 106](https://reader033.fdocuments.us/reader033/viewer/2022061603/55533e97b4c905e12e8b5419/html5/thumbnails/54.jpg)
Effective Inventory Management

Periodic (Annual) Inventory
• Periodic inventory is a method bywhich any inventory sold is physicallycounted at the end of an accountingperiod.
• To satisfy financial auditors• Determine the value of theinventory• Financial auditors are concernedwith the total value• Planners are concerned with the• item detail
![Page 59: Management 106](https://reader033.fdocuments.us/reader033/viewer/2022061603/55533e97b4c905e12e8b5419/html5/thumbnails/59.jpg)
Cycle Counting
• A method of keeping track of inventoryby performing inventory counts constantly,or on a frequent and regular basis, insteadof once per year or once per quarter.
• Count inventory continually throughout the year• Predetermined schedule
some items counted frequentlydepending on valuepast history of problems
• Count some items every day
