A warehouse is a location with adequate facilitieswhere volume shipment are received from aproduction centre, broken down, reassembledinto combinations representing a particular orderor orders, and shipped to the customers location
or locations
8/2/2019 Puc l400 Lecture 1

Warehousing Refers to the activities involving storage of
goods on a large-scale in a systematic andorderly manner and making them available
conveniently when needed.
In other words, warehousing means holding orpreserving goods in huge quantities from thetime of their purchase or production till theiractual use or sale

From the definitions;
A warehouse is typically viewed as a place to store
inventory.
The warehouse is where the supply chain holds or
stores goods.

A WAREHOUSE
..In the past, warehouse management could focus
solely on controlling the movement and storage of
materials within an warehouse operation
and processing the associated transactions of
picking, packing, shipping and receiving.
However, todays systems must integrate
warehouse operations, so that visibility extends
beyond the four walls of the warehouse and to the
rest of the value chain

Benefits of Warehousing
Consolidation
Shipment consolidation is an economic benefit ofwarehousing.
With this arrangement, the consolidating warehousereceives and consolidates materials from a number ofmanufacturing plants destined to a specific customeron a single transportation shipment.
The benefits are the realization of the lowest possibletransportation rate and reduced congestion at acustomer's receiving dock.
8/2/2019 Puc l400 Lecture 1
21/103
Warehousing can provide both
economic and service benefits Economic benefits of
warehousing occur when overalllogistics costs are reduced Consolidation and break-bulk
Sorting Seasonal storage
Reverse logistics
Service benefits are justified bysales improvements that more than
offset added cost Spot-stocking
Full line stocking
Value-added services

Consolidation Warehouses
8/2/2019 Puc l400 Lecture 1
23/103
23
Consolidation Warehouses
The primary benefit of consolidation is that itcombines the logistical flow of several smallshipments to a specific market area.
Consolidation warehousing may be used by a singlefirm, or a number of firms may join together and usea for-hire consolidation service.
Through the use of such a program, each individua1manufacturer or shipper can enjoy lower totaldistribution cost than could be realized on a directshipment basis individually.
8/2/2019 Puc l400 Lecture 1
24/103
24
Break bulk warehouses
Break bulk warehouse operations are similar toconsolidation except that no storage is performed.
A break bulk operation receives combined customerorders from manufacturers and ships them toindividual customers.
The break bulk warehouse sorts or splits individualorders and arranges for local delivery.
Because the long-distance transportation movementis a large shipment, transport costs are lower andthere is less difficulty in tracking.

26
Processing/Postponement
Warehouses can also be used to postpone, or delay,production by performing processing and lightmanufacturing activities.
A warehouse with packaging or labeling capabilityallows postponement of final production until actualdemand is known.
For example, vegetables can be processed andcanned in "brights" at the manufacturer.
Brights are cans with no pre-attached labels.
8/2/2019 Puc l400 Lecture 1
27/103
27
Processing/Postponement
The use of brights for a private label productmeans that the item does not have to becommitted to a specific customer or package
configuration at the manufacturer's plant.
Once a specific customer order is received,the warehouse can complete final processingby adding the label and finalizing thepackaging.
8/2/2019 Puc l400 Lecture 1
28/103
28
Processing/Postponement
Processing and postponement provide two economicbenefits:
First, risk is minimized because final packaging is notcompleted until an order for a specific label andpackage has been received.
Second, the required level of total inventory can bereduced by using the basic product (brights) for avariety of labeling and packaging configurations.
8/2/2019 Puc l400 Lecture 1
29/103
29
Stockpiling
The economic benefit of stockpiling comes from theneed of seasonal storage.
For example, lawn furniture and toys are producedyear-round and primarily sold during a very shortmarketing period.
In contrast, agricultural products are harvested atspecific times with subsequent consumptionoccurring throughout the year.
Both situations require warehouse stockpiling tosupport marketing efforts.
Stockpiling provides an inventory buffer, which allowsproduction efficiencies within the constraints imposedby material sources and the customer.
8/2/2019 Puc l400 Lecture 1
30/103
30
Service Benefits
Five basic service benefits are achievedthrough warehousing:
spot stock,
assortment, mixing,
production support, and
market presence.
8/2/2019 Puc l400 Lecture 1
31/103
31
Spot Stock
Under spot stocking, a selected amount of a firm'sproduct line is placed or "spot stocked" in awarehouse to fill customer orders during a criticalmarketing period.
In particular, manufacturers with limited or highlyseasonal product lines are partial to this service.
Rather than placing inventories in warehousefacilities on a year-round basis or shipping directlyfrommanufacturing plants, delivery time can besubstantially reduced by advanced inventorycommitment to strategic markets.
8/2/2019 Puc l400 Lecture 1
32/103
32
Spot Stock
Utilizing warehouse facilities forstock spotting allowsinventories to be placed in a variety of marketsadjacent to key customers just prior to a maximumperiod of seasonal sales.
Suppliers of agricultural products to farmers often usespot stocking to position their products closer to aservice-sensitive market during the growing season.
Following the sales season, the remaining inventoryis withdrawn to a central warehouse.
8/2/2019 Puc l400 Lecture 1
33/103
33
Assortment
An assortment warehouse stocks productcombinations in anticipation of customer orders.
The assortments may represent multiple productsfromdifferent manufacturers or special assortments
as specified by customers. In the first case, forexample, an athletic wholesaler
would stock products froma number of clothingsuppliers so that customers can be offeredassortments.
In the second case, the wholesaler would create aspecific team uniform including shirt, pants, andshoes.
8/2/2019 Puc l400 Lecture 1
34/103
34
Assortment vs. Spot Stock
The differential between stock spotting and completeline assortment is the degree and duration ofwarehouse utilization.
A firm following a stock spotting would typicallywarehouse a narrow product assortment and place
stocks in a large number of small warehousesdedicated to specific markets fora limited timeperiod.
Distribution assortment warehouse usually has abroad product line, is limited to a fewstrategic
locations, and is functional year-round. The combined assortments also allow larger
shipment quantities, which in turn reducetransportation cost.
8/2/2019 Puc l400 Lecture 1
35/103
35
Mixing
In a typical mixing situation, truckloads of productsare shipped from manufacturing plants towarehouses.
Each large shipment enjoys the lowest possible
transportation rate. Upon arrival at the mixing warehouse, factory
shipments are unloaded and the desiredcombination of each product for each customer ormarket is selected.
When plants are geographically separated, overalltransportation charges and warehouse requirementscan be reduced by mixing.
8/2/2019 Puc l400 Lecture 1
36/103
36
Production Support
Production support warehousing provides a steadysupply of components and materials to assemblyplants.
Safety stocks on items purchased from outsidevendors may be justified because of long lead timesor significant variations in usage.
The operation of a production support warehouse isto supply or "feed" processed materials, components,and subassemblies into the assembly plant in aneconomic and timely manner.
8/2/2019 Puc l400 Lecture 1
37/103
37
Market Presence
While a market presence benefit may not be soobvious, it is often cited by marketing managers as amajor advantage of local warehouses.
The market presence factor is based on theperception or belief that local warehouses can bemore responsive to customer needs and offer quickerdelivery than more distant warehouses.
As a result, it is also thought that a local warehousewill enhance market share and potentially increaseprofitability.
8/2/2019 Puc l400 Lecture 1
38/103
38
Warehouse Operating Principles
Once it has been determined to use awarehouse, the next step is designing it.
Whether the warehouse is a small manual
operation or a large automated facility, thefollowing three principles are relevant:
Design criteria,
Handling technology, and
Storage plan.
8/2/2019 Puc l400 Lecture 1
39/103
39
Design Criteria
Warehouse design criteria address physicalfacility characteristics and product movement.
Three factors to be considered in the design
process are: the number of stories in the facility,
height utilization, and
product flow.
8/2/2019 Puc l400 Lecture 1
40/103
40
Number of stories in the facility
The ideal warehouse design is limited to a singlestory so that product does not have to be moved upand down.
The use of elevators to move product from one floor
to the next requires time and energy. The elevator is also often a bottleneck in product flow
since many material handlers are usually competingfor a limited number of elevators.
While it is not always possible, particularly in centralbusiness districts where land is restricted orexpensive, warehouses should be limited to a singlestory.
8/2/2019 Puc l400 Lecture 1
41/103
41
Height utilization
Regardless of facility size, the design shouldmaximize the usage of the available cubic space byallowing for the greatest use of height on each floor.
Most warehouses have 20- to 30-foot ceilings(1 foot = 12 inch; 1 inch = 2.54 cm), although modern
automated and high-rise facilities can effectively useceiling heights up to 100 feet.
Through the use of racking or other hardware, itshould be possible to store products up to thebuilding's ceiling.
Maximum effective warehouse height is limited by thesafe lifting capabilities of material-handlingequipment, such as forklifts.
8/2/2019 Puc l400 Lecture 1
42/103
42
Product flow
Warehouse design should also allow for straightproduct flow through the facility whether items arestored or not.
In general, this means that product should bereceived at one end of the building, stored in themiddle, and then shipped from the other end.
Straight-line product flow minimizes congestion andconfusion.
8/2/2019 Puc l400 Lecture 1
43/103
43
Handling technology
The second principle focuses on theeffectiveness and efficiency of material-
handling technology.
The elements of this principle concern:
movement continuity and movement scale economies.
8/2/2019 Puc l400 Lecture 1
44/103
44
Movement continuity
Movement continuity means that it is better for amaterial handler or piece of handling equipment tomake a longer move than to have a number ofhandlers make numerous, individual, short segmentsof the same move.
Exchanging the product between handlers or movingit from one piece of equipment to another wastestime and increases the potential for damage.
Thus, as a general rule, fewer longer movements inthe warehouse are preferred.
8/2/2019 Puc l400 Lecture 1
45/103
45
Movement scale economies
Movement scale economies imply that all warehouseactivities should handle or move the largest quantitiespossible.
Instead of moving individual cases, warehouseactivities should be designed to move groups of
cases such as pallets or containers. This grouping or batching might mean that multiple
products or orders must be moved or selected at thesame time.
While this might increase the complexity of an
individual's activities since multiple products or ordersmust be considered, the principle reduces thenumber of activities and the resulting cost.
8/2/2019 Puc l400 Lecture 1
46/103
46
Storage Plan
According to the third principle, a warehouse designshould consider product characteristics, particularlythose pertaining to volume, weight, and storage.
Product volume is the major concern when defining awarehouse storage plan.
High-volume sales or throughput product should bestored in a location that minimizes the distance it ismoved, such as near primary aisles and in lowstorage racks.
Such a location minimizes travel distance and the
need for extended lifting. Conversely, low-volume product can be assigned
locations that are distant from primary aisles orhigher up in storage racks.
8/2/2019 Puc l400 Lecture 1
47/103
47
A Sample Storage Area
8/2/2019 Puc l400 Lecture 1
48/103
48
Storage Plan
Similarly, the plan should include a specific strategyfor products dependent on weight and storagecharacteristics.
Relatively heavy items should be assigned tolocations low to the ground to minimize the effort and
risk of heavy lifting. Bulky or low-density products require extensive
storage volume, so open floor space or high-levelracks can be used for them.
On the other hand, smaller items may require storage
shelves or drawers. The integrated storage plan must consider and
address the specific characteristics of each product.
8/2/2019 Puc l400 Lecture 1
49/103
49
Types of warehouses
Basic Warehouses generally include: (1) Private warehouses, (2) Public warehouses, and (3) Contract warehouses.
A private warehouse facility is owned and managedby the same enterprise that owns the merchandisehandled and stored at the facility.
A public warehouse, in contrast, is operated as anindependent business offering a range of services-such as storage, handling, and transportation- on thebasis of a fixed or variable fee.
Public warehouse operators generally offer relativelystandardized services to all clients.
8/2/2019 Puc l400 Lecture 1
50/103
50
Types cont.....
Contract warehousing, which is evolving from the publicwarehouse segment, provides benefits of both the privateand public alternatives.
Contract warehousing is a long term, mutually beneficialarrangement which provides unique and specially tailoredwarehousing and logistics services exclusively to oneclient, where the vendor and client share the risksassociated with the operation.
Important dimensions that differentiate contractwarehousing operators from public warehouse operatorsare the extended time frame of the service relationship,tailored services, exclusivity, and shared risk.
8/2/2019 Puc l400 Lecture 1
51/103
51
Private Warehouses
A private warehouse is operated by the firm owningthe product.
The actual facility, however, may be owned or
leased.
The decision as to which strategy best fits anindividual firm is essentially financial.
Often it is not possible to find a warehouse for leasethat fits the exact requirements of a firm.
8/2/2019 Puc l400 Lecture 1
52/103
52
Private Warehouses
The major benefits of private warehousing includecontrol, flexibility, cost, and other intangible benefits.
Private warehouses provide more control since theenterprise has absolute decision-making authorityover all activities and priorities in the facility.
This control facilitates the ability to integratewarehouse operations with the rest of the firm'sinternal logistics process.
8/2/2019 Puc l400 Lecture 1
53/103
53
Private Warehouses
Private warehousing is usually considered less costlythan public warehousing because private facilitycosts do not have a profit markup.
This perceived benefit, however, may be misleadingsince public warehouses often are more efficient or
may operate at lower wage scales. Private warehousing has also some intangible
benefits, particularly with respect to market presence. A private warehouse with a firm's name on it may
produce customer perceptions of responsiveness and
stability. This perception sometimes provides a firm with a
marketing advantage over other enterprises.
8/2/2019 Puc l400 Lecture 1
54/103
54
Public Warehouses
On the basis of the range of specialized operationsperformed, public warehouses are classified as
(1) general merchandise,
(2) refrigerated, (3) special commodity,
(4) bonded, and
(5) household goods and furniture.
Each warehouse type differs in its material handlingand storage technology as a result of the product andenvironmental characteristics.
8/2/2019 Puc l400 Lecture 1
55/103
55
Public Warehouses
General merchandise warehouses are designed tohandIe general package commodities such as paper,small appliances, and household supplies.
Refrigerated warehouses (either frozen or chilled)handle and maintain food, medical items, andchemical products with special temperaturerequirements.
Commodity warehouses are designed to handlebulk material or items with special handlingconsiderations, such as tires or clothing.
8/2/2019 Puc l400 Lecture 1
56/103
56
Public Warehouses
Bonded warehouses are licensed by thegovernment to store goods prior to payment of taxesor duties.
They exert very tight control over all movements in
and out of the facility since government documentsmust be filed with each move.
For example, cigarettes are often stored in bondedwarehouses prior to having the tax stamp applied.
This tactic saves the firm money by delaying taxpayments; it also reduces inventory valuesubstantially.
8/2/2019 Puc l400 Lecture 1
57/103
57
Public Warehouses
Finally, a household goods or furniturewarehouse is designed to handle and store
large, bulky items such as appliances andfurniture.
Of course, many public warehouses offercombinations of these operations.
8/2/2019 Puc l400 Lecture 1
58/103
58
Public Warehouses
From a financial perspective, public warehousingmay have a lower variable cost than comparableprivately operated facilities.
The lower variable cost may be the result of lower
pay scales, better productivity, or economy of scale.
Public warehouses certainly result in lower capitalcosts.
When management performance is judged according
to return on investment (ROI), the use of publicwarehousing can substantially increase enterprisereturn.
8/2/2019 Puc l400 Lecture 1
59/103
59
Public Warehouses
Public warehousing offers flexibility in that it is easyto change the location, size, and number of facilities,allowing a firm to quickly respond to supplier,customer, and seasonal demands.
Private warehouses are relatively fixed and difficult to
change because buildings have to be constructed orsold.
Public warehousing can also offer significant scaleeconomies since the volume for each customer isleveraged with that of other users.
This results in high-volume operations that canspread fixed costs and justify more efficient handlingequipment.
8/2/2019 Puc l400 Lecture 1
60/103
60
Public Warehouses
A public warehouse can also leveragetransportation by providing delivery of loadsthat represent many public warehousecustomers.
For example, rather than have vendor A andvendor B each deliver to a retail store fromtheir own warehouse, a public warehouseserving both vendors could deliver a singlecombined load more efficiently.
8/2/2019 Puc l400 Lecture 1
61/103
61
Public Warehouses
A public warehouse charges clients a basic fee forhandling and storage.
In the case of handling, the charge is based on thenumber of cases or pounds handled.
For storage, the charge is assessed on the numberof cases or weight in storage during the month.
Such charges normally exceed the cost of privatewarehousing if adequate private facility volumeexists.
However, when economies of scale are not possiblein a private facility, public warehousing may be a low-cost alternative.
8/2/2019 Puc l400 Lecture 1
62/103
62
Contract Warehouses
Contract warehousing combines the bestcharacteristics of both private and public operations.
The long-term relationship and shared risk result in
lower cost than typical public warehousearrangements.
Contract warehouse operations can provide benefitsof expertise, flexibility, and economies of scale bysharing management, labor, equipment, andinformation resources across a number of clients.
8/2/2019 Puc l400 Lecture 1
63/103
63
Contract Warehouses
Although it is common for contract warehouseoperators to share resources across clients in thesame industry such as grocery products, it is notcommon that direct competitors will want to share
resources.
Contract warehouse operators are also expandingthe scope of their services to include other logistics
activities such as transportation, inventory control,order processing, customer service, and returnsprocessing.
8/2/2019 Puc l400 Lecture 1
64/103
64
Contract Warehouses
For example, Rich Products, a frozen foodmanufacturer in Buffalo, New York, has increasinglyutilized contract warehousing.
Since 1992, Rich has had a long term commitmentwith a refrigerated warehousing and distributioncompany, Christian Salvesen, for storage, handling,and distribution services at its facilities in New York.
The nature of the arrangement benefits both partiesand allows Rich to expand its distribution networkwithout incurring any fixed facility cost.
8/2/2019 Puc l400 Lecture 1
65/103
65
Contract Warehouses
Rich is assured that there will always be storagespace for its products.
Christian Salvesen doesn't have to be concerned
with filling space in its warehouses and can focus onproviding service.
Moreover, the longer Rich Products utilizes Christian
Salvesen's services, the better the contractwarehousing firm will be able to understand Rich'sbusiness needs and provide customized services.

Warehousing Strategy
Many firms utilize a combination of private, public,and contract facilities.
A private or contract facility may be used to coverbasic year round requirements, while public facilities
are used to handle peak seasons. In other situations, central warehouses may be
private, while market area or field warehouses arepublic facilities.
Each use of warehouse combinations will bediscussed now.
8/2/2019 Puc l400 Lecture 1
71/103
71
Warehousing Strategy
Full warehouse utilization throughout a year is aremote possibility.
As a planning rule, a warehouse designed for full-capacity utilization will in fact be fully utilized between
75 and 85 percent of the time. Thus from 15 to 25 percent of the time, the space
needed to meet peak requirements is not utilized.
In such situations, it may be more efficient to build
private facilities to cover the 75 percent requirementand use public facilities to accommodate peakdemand.

73
Warehousing Strategy
The second form of combined public warehousingmay result from market requirements.
A firm may find that private warehousing is justified atspecific locations on the basis of distribution volume.
In other markets, public facilities may be the least-cost option.
In logistical system design the objective is todetermine whatever combination of warehousestrategies most economically meets customer serviceobjectives.
8/2/2019 Puc l400 Lecture 1
74/103
74
Warehousing Strategy
An integrated warehouse strategy focuses on twoquestions.
The first concerns how many warehouses should beemployed.
The second question concerns which warehousetypes should be used to meet market requirements.
For many firms, the answer is a combination that canbe differentiated by customer and product.
Specifically, some customer groups may be servedbest from a private warehouse, while a publicwarehouse may be appropriate for others.
8/2/2019 Puc l400 Lecture 1
75/103
75
Warehousing Strategy
Other qualitative factors that should be consideredinclude:
(1) presence synergies,
(2) industry synergies,
(3) operating flexibility,
(4) location flexibility, and
(5) scale economies.
Each consideration and its rationale will be discussed.
8/2/2019 Puc l400 Lecture 1
76/103
76
Presence synergies
Presence synergies refer to the marketing benefitsof having inventory located nearby in a building thatis clearly affiliated with the enterprise (e.g., thebuilding has the firm's name on the door).
It is widely thought that customers are morecomfortable when suppliers maintain inventory innearby locations.
Products and customers that benefit from localpresence should be served from private or contractfacilities.
8/2/2019 Puc l400 Lecture 1
77/103
77
Industry synergies
Industry synergies refer to the operating benefits ofcollocating with other firms serving the same industry.
For example, firms in the grocery business oftenreceive substantial benefits when they share public
warehouse facilities with other suppliers serving thesame industry.
Reduced transportation cost is the major benefitsince joint use of the same public warehouse allowsfrequent delivery of consolidated loads from multiple
suppliers. Public and contract warehousing increase the
potential for industry synergy.
8/2/2019 Puc l400 Lecture 1
78/103
78
Operating flexibility
Operating flexibility refers to the ability to adjustinternal policies and procedures to meet product andcustomer needs.
Since private warehouses operate under the
complete control of the enterprise, they are usuallyperceived to demonstrate more operating flexibility.
On the other hand, a public warehouse often employspolicies and procedures that are consistent across itsclients to minimize operating confusion.
There are many public and contract warehouseoperations that have demonstrated substantialflexibility and responsiveness.
8/2/2019 Puc l400 Lecture 1
79/103
79
Location flexibility
Location flexibility refers to the ability to quicklyadjust warehouse location and number in accordancewith seasonal or permanent demand changes.
For example, in-season demand for agricultural
chemicals requires that warehouses be located nearmarkets that allow customer pickup.
Outside the growing season, however, these localwarehouses are unnecessary.
Thus, the desirable strategy is to be able to open and
close local facilities seasonally. Public and contract warehouses offer the location
flexibility to accomplish such requirements.

Scale economies
Scale economies refer to the ability to reducematerial-handling and storage through application ofadvanced technologies.
High-volume warehouses generally have greateropportunity to achieve these benefits because they canspread technology's fixed cost over larger volumes.
In addition, capital investment in automated equipmentcan reduce direct variable cost.
Public and contract warehouses are generallyperceived to offer better scale economies since theyare able to design operations and facilities to meethigher volumes of multiple clients.

Planning the Distribution Warehouse
The initial decisions of warehousing are related toplanning.
A master plan of the layout, space requirements, and
material-handling design should be developed firstand a specific site for the warehouse selected.
These decisions establish the character of the
warehouse, which, in turn determines the degree ofattainable handling efficiency.

Site Selection
Location analysis techniques are available to assist inselecting a general area for warehouse location.
Once location analysis is completed, a specificbuilding site must be selected.
Three areas in a community may be considered forlocation:
1) commercial zones, 2) outlying areas served bymotor truck only, and 3) central or downtown areas.
The primary factors in site selection are the
availability of services and cost. The cost of procurement is the most important factor
governing site selection.

Site Selection
A warehouse need not be located in a majorindustrial area.
In many cities, one observes warehouses among
industrial plants and in areas zoned for light or heavyindustry.
Interestingly, this is not a legal necessity because
most warehouses can operate under the restrictionsplaced on commercial property.

Site Selection
Beyond procurement cost, setup and operatingexpenses such as rail sidings, utility expenses, taxes,insurance rates, and highway access requireevaluation.
These expenses vary between sites.
For example, a food distribution firm recently rejectedwhat otherwise appeared to be a totally satisfactory
site because of insurance rates.
The site was located near the end of a water main.

Site Selection
During most of the day, adequate water supplieswere available to handle operational and emergencyrequirements.
The only possible water problem occurred during twoshort periods each day.
From 6:30 to 8:30 in the morning and from 5 to 7 inthe evening, the demand for water along the line wasso great that a sufficient supply was not available tohandle emergencies.
Because of this deficiency, abnormally highinsurance rates were required and the site wasrejected.

Site Selection
Several other requirements must be satisfiedbefore a site is purchased.
The location must offer adequate room for
expansion. Necessary utilities must be available.
The soil must be capable of supporting thestructure, and the site must be sufficiently
high to afford proper drainage (su akna izinverme).

Product-Mix Considerations
The design and operation of a warehouse are relateddirectly to the character of the product mix.
Each product should be analyzed in terms of annual sales,stability of demand, weight, and packaging.
It is also desirable to determine the total size and weightof the average order processed through the warehouse.
These data provide necessary information for determiningrequirements in warehouse space, design and layout,material-handling equipment operating procedures, andcontrols.

Expansion
Future expansion is often neglected when anenterprise consider initial establishment of itswarehouse facilities.
Inclusion of a warehouse into the logistical system
should be based partially on estimated requirementsfor future operations.
Well-managed organizations often establish five- toten-year expansion plans.
Such expansion considerations may requirepurchase or option of a site three to five times thesize of the initial structure.

Expansion
Special construction is often considered toease expansion without seriously affectingnormal operations.
Some walls may be constructed of semi-permanent materials to allow easy removal.
Floor areas, designed to support heavymovements, are extended to these walls in amanner that facilitates expansion.

Selection of Material-Handling System
A material-handling system is one of the initialconsiderations of warehouse planning.
Movement is the main function within a warehouse.
Consequently, the warehouse is viewed as astructure designed to facilitate maximum productflow.
It is important to stress that the material-handlingsystem should be selected early in the warehousedesign stage.

Warehouse Layout
Layout of a warehouse depends on the proposedmaterial handling system and requires developmentof a floor plan to facilitate product flow.
It is difficult to generalize about warehouse layouts
since they must be refined to fit specific needs.
If pallets are to be utilized, the first step is todetermine the pallet size.
A pallet of nonstandard size may be desirable forspecialized products, but whenever possible,standardized pallets should be used because of theirlower cost.

Warehouse Layout
The most common sizes are 40 by 48 inches and 32by 40 inches.
In general, the larger the pallet load, the lower the
cost of movement per package over a given distance.
The packages to be placed on the pallet and therelated patterns will determine, to a certain extent,the size of pallet best suited to the operation.
Regardless of the size finally selected, managementshould adopt one size for the total operation.

Warehouse Layout
The second step in planning a layout involves thepallet positioning.
The basic method of positioning pallets in a
mechanized warehouse is a ninety-degree, orsquare, placement.
Square placement means that the pallet is positionedperpendicular to the aisle.
The square method is widely used because of layoutease.

Pilferage Protection
Protection against theft of merchandise has becomea major factor in warehouse operations. Such protection is required as a result of the
increased vulnerability of firms to riots and civildisturbances.
All normal precautions employed throughout theenterprise should be strictly enforced at eachwarehouse.
Security begins at the fence.
As standard procedure, only authorized personnelshould be permitted into the facility and surroundinggrounds and entry to the warehouse yard should becontrolled through a single gate.

Without exception, no private automobile-regardlessof management rank or customer status-should beallowed to penetrate the yard adjacent to thewarehouse.
To illustrate the importance of the stated guidelines,the following actual experience may be helpful.
A particular firm enforced the rule that no private
vehicles should be permitted in the warehouse yard. Exceptions weremade fortwo handicapped office

One night afterwork, one of these employeesaccidentally discovered a bundle taped under onefender of his car.
Subsequent checking revealed that the car was
literally a delivery truck. The matter was promptly reported to security, which
informed the employee not to alter any packagestaped to the car and to continue parking inside theyard.
Over the next several days, the situation was fullyuncovered, with the ultimate arrest and conviction ofseveral warehouse employees who confessed tostealing over $100,000of company merchandise.

Not all pilferage occurs on an individual basis.
Numerous instances have been discovered whereorganized efforts between warehouse personnel and
truck drivers resulted in deliberate over-picking orhigh-for-low-value product substitution in order tomove unauthorized merchandise out of thewarehouse.
Employee rotation, total case counts, and occasionalcomplete line-item checks can reduce vulnerability tosuch collaboration.

Product Deterioration
Within the warehouse, a number of factors canreduce a product or material to a non-usable or non-marketable state.
The most obvious form of product deterioration isdamage from careless transfer or storage.
Another major form of deterioration is non-
compatibility of products stored in the same facility.

A constant concern is the carelessness of warehouse
employees.
In this respect, the forklift truck may well bemanagement's worst enemy.
Regardless of how often operators are warnedagainst carrying overloads, some still attempt suchshortcuts when not properly supervised.

Product Deterioration
In one situation, a stack of four pallets was droppedoff a forklift truck at the receiving dock of a foodwarehouse.
Standard procedure was to move two pallets perload.
The value of the damaged merchandise exceededthe average daily profit of two supermarkets.
Product deterioration from careless handling within
the warehouse is a form of loss that cannot beinsured against and constitutes a 100 percent costwith no compensating revenue.
