There are four types of production layouts for process planning for plant layout in details

1. Layout the way in the way keeps its machines competing in one place, in other words, the cars are arranged according to their function, put all the milling operations in another place, grasp each type in the track, all the lathe in one place and so arranged according

function now understand the layout by an example from the storeroom job will go first to the lathe section after completing the lathe operation it will enter the milling section then job will go to broaching section then it will enter the drill section after drilling finish job will go for inspection

if the job dimensions are correct then 1. better utilization of available so product quality will be better 3. it will go to the stock room what are the advantages of process layout equipment 2. workers are dealing with only one type of machines workers in one section are not affected

by the operation carried out in another disadvantages of process layout 1. for the same amount of production the process layout needs more space 2. automatic material handling is 3. production control becomes difficult section difficult 4. raw material has to travel a longer distance for being processed to finished

goods this increases material handling and product layout is also known as line various operations on raw material are associated costs it needs more inspection and efficient coordination number two product layout layout performed in a sequence

and machines are placed accordingly to product layout applies in mass production where a huge number of the same product and continuous flow of the the production flow line process is needed for example a job need laid operation first the second operation is drilling then milling then grinding

in this case the machine will arrange according to the sequence of operation advantages of product layout volume of production 1. less space required for the same 2. material handling is lesser which reduces time and cost 3. coordination will be better production planning and control will

easier 4. fewer skilled workers maybe do the work disadvantages of product layout determines the layout a change in product involves a major change in 1. in process layout specified product layout thus flexibility in the layout is reduced 2.

rate of production depends upon the output rate of the slowest machine this leads to excessive idle time of another machine if the production line is not balanced 3. it is difficult to increase production beyond the capacities of the production line a combination layout combines the 3. combination layout

advantages of both process layout and product layout these days pure process and product layouts are air a combination layout is possible where the item is made in different types and size in such case machine rearrange in a process layout but the product layout is then

arranged in the sequence of various types and sizes of the products after gear cutting it will enter the then job will go to gear finishing for example a job first need to go to blank forging hammers then hobbing machines for cutting gear heat treatment furnace machines

advantages of combination layout 1. it combines the advantages of both process and product layout a number of items are produced in the same sequence but in small numbers and no item justified for individual production line 2. combination layout can be useful when 4. fixed position layout in other types of layouts the product

moves past the stationary production equipment but in a fixed position layout the product kept stationary position layout is applicable and equipment moves around it fixed in ship building aircraft manufacturer etc during an aircraft manufacturing frame of the aircraft is fixed at one position engines

airframe instruments are made separately and assembled together at the end in this case aircraft is stationary and worker r move around it advantages of fixes position layout 1. it is possible to assign one or more skilled workers from the start of a project to finish in order to ensure equipment continuity of work

2. involves the least movement of manufacturing of large size product is 3. a number of quite different projects can be taken with the same layout disadvantages of fixed position layout materials possible 1. it involves a low content of work in progress 2. it involves high equipment handling
