TYPES OF LAYOUT

As discussed so far the works layout facilitates the agreement of machines, equipment and other physical installations in a planned mode within the mill premises. An enterpriser must possess an expertness to put down a proper layout for new or bing workss. It differs from works to works, from location to location and from industry to industry.

But the basic rules regulating works layout are more or less same.Equally far as little concern is concerned, it requires a smaller country or infinite and can be located in any sort of edifice every bit long as the infinite is available and it is convenient. Plant layout for Small Scale concern is closely linked with the mill edifice and built up country.From the point of position of works layout, we can sort concern or unit into three classs:

1. Manufacturing units

2. Traders

3. Service EstablishmentsA

1. Manufacturing unitsIn instance of fabricating unit, works layout may be of four types:( a ) Merchandise or line layout:Under this, machines and equipments are arranged in one line depending upon the sequence of operations required for the merchandise.

The stuffs move form one workstation to another consecutive without any backtracking or divergence. Under this, machines are grouped in one sequence. Therefore stuffs are fed into the first machine and finished goods travel automatically from machine to machine, the end product of one machine going input of the following, e.g. in a paper factory, bamboos are fed into the machine at one terminal and paper comes out at the other terminal.

The natural stuff moves really fast from one workstation to other Stationss with a minimal work in progress storage and stuff handling.The grouping of machines should be done maintaining in head the following general rules.a ) All the machine tools or other points of equipments must be placed at the point demanded by the sequence of operationsB ) There should no points where one line crossed another line.degree Celsius ) Materials may be fed where they are required for assembly but non needfullyat one point.vitamin D ) All the operations including assembly, proving wadding must be included in thelineAAdvantages: Merchandise layout provides the undermentioned benefits:a ) Low cost of stuff handling, due to consecutive and short path and absence of backtrackingAB ) Smooth and uninterrupted operationsdegree Celsius ) Continuous flow of workvitamin D ) Lesser investing in stock list and work in advancementvitamin E ) Optimum usage of floor infinitedegree Fahrenheit ) Shorter processing clip or quicker end productg ) Less congestion of work in the procedureH ) Simple and effectual review of work and simplified production controlI ) Lower cost of fabricating per unitDisadvantages: Merchandise layout suffers from following drawbacks:a.

High initial capital investing in particular purpose machineB. Heavy operating expense chargesc. Breakdown of one machine will halter the whole production procedured. Lesser flexibleness as specially laid out for peculiar merchandise.Suitability: Merchandise layout is utile under following conditions:1 ) Mass production of standardised merchandises2 ) Simple and insistent fabrication procedure3 ) Operation clip for different procedure is more or less equal4 ) Reasonably stable demand for the merchandise5 ) Continuous supply of stuffsTherefore, the fabricating units affecting uninterrupted fabrication procedure,bring forthing few standardised merchandises continuously on the house ‘s ain specifications and in expectancy of gross revenues would prefer merchandise layout e.g.chemicals, sugar, paper, gum elastic, refineries, cement, cars, nutrient processingand electronics etc.

A( B ) Procedure layout:In this type of layout machines of a similar type are arranged together at one topographic point.E.g. Machines executing boring operations are arranged in the boringsection, machines executing projecting operations be grouped in the castingsection.

Therefore the machines are installed in the workss, which follow theprocedure layout.Therefore, such layouts typically have boring section, milling section, welding section, heating section and picture section etc. The procedureor functional layout is followed from historical period. It evolved from the handcraft method of production.

The work has to be alloca ted to eachsection in such a manner that no machines are chosen to make every bit many different occupationas possible i.e. the accent is on general intent machine.The grouping of machines harmonizing to the procedure has to be done maintaining in head the undermentioned rulesa ) The distance between sections should be every bit short as possible for avoidinglong distance motion of stuffsB ) The sections should be in sequence of operationsdegree Celsius ) The agreement should be convenient for review and supervisingAdvantages: Procedure layout provides the undermentioned benefitsa ) Lower initial capital investing in machines and equipments. There is highgrade of machine use, as a machine is non blocked for a individual merchandiseB ) The operating expense costs are comparatively lowdegree Celsius ) Change in end product design and volume can be more easy adapted to the end productof assortment of merchandisesvitamin D ) Breakdown of one machine does non ensue in complete work arrestvitamin E ) Supervision can be more effectual and specializeddegree Fahrenheit ) There is a greater flexibleness of range for enlargement.Disadvantages: Merchandise layout suffers from following drawbacksa. Material handling costs are high due to turn backingB.

More skilled labor is required ensuing in higher cost.c. Time spread or slowdown in production is higherd. Work in progress stock list is high necessitating greater storage infinitee. More frequent review is needed which consequences in dearly-won supervisingSuitability: Procedure layout is adopted when1. Merchandises are non standardized2.

Measure produced is little3. There are frequent alterations in design and manner of merchandise4. Job shop type of work is done5. Machines are really expensiveTherefore, procedure layout or functional layout is suited for occupation order productionaffecting non-repetitive procedures and client specifications and non standardizedmerchandises, e.g.

tailoring, visible radiation and heavy technology merchandises, madeto order furniture industries, jewellery.

( degree Celsius ) Fixed Position or Location Layout

In this type of layout, the major merchandise being produced is fixed at one location.Equipment labor and constituents are moved to that location. All installations arebrought and arranged around one work centre. This type of layout is non relevant for little graduated table entrepreneur.

AAdvantages: Fixed place layout provides the undermentioned benefitsa ) It saves clip and cost involved on the motion of work from oneworkstation to another.B ) The layout is flexible as alteration in occupation design and operation sequence can beeasy incorporated.degree Celsius ) It is more economical when several orders in different phases of advancement arebeing executed at the same time.vitamin D ) Adjustments can be made to run into deficit of stuffs or absence of workersby altering the sequence of operations.Disadvantages: Fixed place layout has the undermentioned drawbacksa. Production period being really long, capital investing is really heavyB. Very big infinite is required for storage of stuff and equipment near themerchandise.

c. As several operations are frequently carried out at the same time, there is possibilityof confusion and struggles among different workgroups.Suitability: The fixed place layout is followed in following conditions1. Industry of bulky and heavy merchandises such as engines, ships, boilers,generators, waggon edifice, aircraft fabrication, etc.

2. Construction of edifice, overpasss, dikes.3. Hospital, the medical specialties, physicians and nurses are taken to the patient ( merchandise ) .

( vitamin D ) Combined layout

Certain fabricating units may necessitate all three procedures viz. intermittentprocedure ( occupation stores ) , the uninterrupted procedure ( mass production stores ) and therepresentative procedure combined procedure [ i.e. assorted stores ] .

In most of industries, merely a merchandise layout or procedure layout or fixed locationlayout does non be. Thus, in fabrication concerns where several merchandisesare produced in perennial Numberss with no likeliness of uninterrupted production,combined layout is followed. Generally, a combination of the merchandise andprocedure layout or other combination are found, in pattern, e.g. for industriesaffecting the fiction of parts and assembly, fiction tends to use theprocedure layout, while the assembly countries frequently employ the merchandise layout. In soap,fabrication works, the machinery fabrication soap is arranged on themerchandise line rule, but accessory services such as warming, the fabrication ofglycerol, the power house, the H2O intervention works etc.

are arranged on afunctional footing.

2. Traders

When two mercantile establishments carry about same ware, clients normally buy in theone that is more appealing to them. Therefore, clients are attracted and kept bygood layout i.e. good lighting, attractive colors, good airing, airconditioning, modern design and agreement and even music.

All of these thingsaverage client convenience, client entreaty and greater concern volume.The client is ever impressed by service, efficiency and quality. Hence, thelayout is indispensable for managing ware, which is arranged as per the infiniteavailable and the type and magnitude of goods to be sold maintaining in head theconvenience of clients.There are three sorts of layouts in retail operations today.1.

Self service or modified self service layout2. Full service layout3. Particular layoutsThe self-service layouts, cuts down on gross revenues clerk ‘s clip and let clients tochoice ware for themselves. Customers should be led through the shop ina manner that will expose them to every bit much show country as possible, e.

g. Grocery storeShops or section shops. In those shops, necessities or convenience goodsshould be placed at the rear of the shop. The usage of colour and lighting is reallyof import to direct attending to interior shows and to do the most of the shopslayout.All operations are non self-service. Certain forte endeavors sell to fewerNumberss of clients or higher priced merchandise, e.g. Apparel, office machines,featuring goods, manner points, hardware, good quality places, jewellery, baggage andaccoutrements, furniture and contraptions are all illustrations of merchandises that requireclip and personal attending to be sold.

These full service layouts provide country andequipment necessary in such instances.Some layouts depend purely on the type of particular shop to be set up, e.g. Televisionfix store, soft ice pick shop, and drive-in soft drink shops are all illustrations ofconcern necessitating particular design. Therefore, good retail layout should be the one,which saves rent, clip and labor.

3. Services centres and constitution

Servicess constitutions such as motels, hotels, eating houses, must give dueattending to client convenience, quality of service, efficiency in presenting servicesand delighting office atmosphere. In today ‘s environment, the clients look for easiness innearing different sections of a service organisation and therefore the layoutshould be designed in a manner, which allows clients speedy and convenient entreeto the installations offered by a service constitution.

FACTORS INFLUENCING LAYOUT

While make up one’s minding his mill or unit or constitution or shop, a small-scaleman of affairs should maintain the undermentioned factors in head:a ) Factory edifice: The nature and size of the edifice determines the floorinfinite available for layout. While planing the particular demands, e.g. airconditioning, dust control, humidness control etc. must be kept in head.B ) Nature of merchandise: merchandise layout is suited for unvarying merchandises whereasprocedure layout is more appropriate for custom-made merchandises.degree Celsius ) Production procedure: In assembly line industries, merchandise layout is better.

Inoccupation order or intermittent fabrication on the other manus, procedure layout is desirable.vitamin D ) Type of machinery: General intent machines are frequently arranged as perprocedure layout while particular purpose machines are arranged harmonizing tomerchandise layoutvitamin E ) Repairs and care: machines should be so ordered that equalinfinite is available between them for motion of equipment and peoplerequired for mending the machines.degree Fahrenheit ) Human needs: Adequate agreement should be made for cloakroom,washroom, cabinets, imbibing H2O, lavatories and other employee installations,proper proviso should be made for disposal of wastewaters, if any.g ) Plant environment: Heat, visible radiation, noise, airing and other facets should bepunctually considered, e.g.

pigment stores and plating subdivision should be located inanother hall so that unsafe exhausts can be removed through properairing etc. Adequate safety agreement should besides be made.Therefore, the layout should be contributing to wellness and safety of employees. Itshould guarantee free and efficient flow of work forces and stuffs. Future enlargement andvariegation may besides be considered while be aftering mill layout.

APPLICABILITY OF PLANT LAYOUT

Plant layout is applicable to all types of industries or workss. Certain workss require particular agreements which, when incorporated make the layout expression distinguishable signifier the types already discussed above. Applicability of works layout in fabrication and service industries is discussed below.

In instance of the fabrication of detergent pulverization, a multi-storey edifice is specially constructed to house the boiler. Materials are stored and poured into theboiler at different phases on different floors. Other installations are besides provided around the boiler at different Stationss.Another pertinence of this layout is the industry of talcum pulverization. Here machinery is arranged vertically i.e. from top to bottom.

Thus, stuff is poured into the first machine at the top and pulverization comes out at the underside of the machinery located on the land floor.Yet another pertinence of this layout is the newspaper works, where the clipcomponent is of supreme importance, the achievement being gapped in seconds.Here works layout must be simple and direct so as to extinguish distance, hold andconfusion.

There must be a perfect coordination of all sections andmachinery or equipments, as stuffs must ne’er neglect.Plant layout is besides applicable to five star hotels as good. Here lodging, saloon,eating house, kitchen, shops, swimming pool, wash, shaving barrooms, shoppingarcades, conference hall, parking countries etc.

should all happen an appropriate topographic point inthe layout. Here importance must be given to cleanliness, elegant visual aspect,convenience and compact expressions, which attract clients.Similarly works layout is applicable to a film hall, where accent is oncomfort, and convenience of the cinemagoers. The projector, screen, sound box,fire contending equipment, atmosphere etc. should be of extreme importance.A works layout applies besides the grouping of machinery, to an agreement forother installations as good. Such installations include having and despatching points,review installations, employee installations, storage etc.

By and large, the receiving and the dispatching sections should be at either terminalof the works. The storage room should be located near to the production, having and despatching centres in order to minimise handling costs. The reviewshould be right following to other despatch section as reviews are done eventually, before despatch.The care section dwelling of lighting, safety devices, fire protection,aggregation and disposal of refuse, bit etc. should be located in a topographic point which iseasy accessible to all the other sections in the works. The other employeeinstallations like lavatory installations, imbibing H2O installations, first assistance room, cafeteria etc.

can be a small off from other sections but should be within easy range of theemployees. Hence, there are the other industries or workss to which works layout isapplicable.The importance of a layout would be better appreciated if one understands the influence of an efficient layout on the fabrication map: it makes it smooth and efficient. Operating efficiencies, such as economic systems in the cost of managing stuffs, minimisation of production holds and turning away of bottlenecksaa‚¬ ” all these depend on a proper layout.

An ideally laid out works reduces fabrication costs through decreased stuffs managing, reduced forces and equipment demands and decreased procedure stock list.The aims or advantages of an ideal layout are outlined in the paragraphs that follow. The advantages are common to all the workss, irrespective of age ; and whether a works employs 50 workers or 50,000 makes no difference in so far as the pertinence of the works layout advantages is concerned. Some of these advantages are: A

Economies in Managing

About 30 % to 40 % of the fabrication cost is accounted for, by stuffs managing.

Every attempt should, therefore, be made to cut down on this cost. Long distance motions should be avoided and specific managing operations must be eliminated. A cynic may state that the cheapest manner to manage stuffs is non to manage them at all. But, in a mill, stuffs have to be handled ; and hence, it all depends on the layout.

Effective Use of Available Area

Every inch of the works country is valuable, particularly in urban countries. Attempts should hence be made to do usage of the available country by be aftering the layout decently. Some stairss for accomplishing this terminal are: location of equipment and services in order that they may execute multiple maps ; development of up-to-date work countries and operator occupation assignments for a full use of the labour force.

Minimization of Production DelaysA

Repeat orders and new clients will be the consequence of prompt executing of orders.

Every direction should seek to maintain to the bringing agendas. Often, the deadline day of the months for bringing of production orders are a bug-a-boo to the direction.Plant layout is a important factor in the timely executing of orders. An ideal layout eliminates such causes of holds as deficit of infinite, long-distance motions of stuffs, spoiled work and therefore contributes to the rapid executing of orders.

Improved Quality ControlTimely executing of orders will be meaningful when the quality of the end product is non below outlooks. To guarantee quality, review should be conducted at different phases of industry. An ideal layout provides for review to guarantee better quality control.

Minimum Equipment Investment

Investing on equipment can be minimized by planned machine balance and location, lower limit handling distances, by the installing of general intent machines and by planned machine burden.

A good works layout provides all these advantages.

Avoidance of Constrictions

Constrictions refer to any topographic point in a production procedure where stuffs tend to stack up or are produced at a velocity, less rapid than the old or subsequent operations. Constrictions are caused by unequal machine capacity, unequal storage infinite or low velocity on portion of the operators. The consequences of constrictions are holds in productions agendas, congestion, accidents and wastage of floor country.

All these may be overcome with an efficient layout.

Better Production Control

Production Control is concerned with the production of the merchandise of the right type, at the right clip and at a sensible cost. A good works layout is a necessity for good production control and provides the production control officers with a systematic footing upon which to construct organisation and processs.

Better Supervision

A good works layout ensures better supervising in two ways:1.

Determining the figure of workers to be handled by a supervisor and2.Enabling the supervisor to acquire a full position of the full works at one glimpse.A good works layout is, hence, the first measure to good supervising.

Improved Use of Labor

Labor is paid for every hr it spends in the mill. The efficiency of a direction lies in using the clip for productive intent. A good works layout is one of the factors in effectual use of labour.

It makes possible single operations, the procedure and flow of stuffs managing in such a manner that the clip of each worker is efficaciously spent on productive operations.

Improved Employee Morale

Employee morale is achieved when workers are cheerful and confident. This province of mental status is critical to the success of any organisation.

Morale depends on:( a ) Better working status ;( B ) Better employee installations ;( degree Celsius ) Reduced figure of accidents ;( vitamin D ) Increased net incomes.Plant layout has a bearing on all these.Avoidance of Unnecessary and Costly ChangesA planned layout avoids frequent alterations which are hard and dearly-won. The incorporation of flexibleness elements in the layout would assist in the turning away of revisions.A
