their delivery

m time

p is often considered to be a subset of

inventory control

it is an effective tool for minimizing

unnecessary inventory investment

material requirement planning is also

useful in production scheduling and

purchasing of materials

functions of material requirement

planning are

1.

control of the inventory levels 2.

assignment of priorities for components

depending upon their delivery dates and

3.

determination of capacity requirements

at a detailed level

now come to inputs to material

requirement planning

mrp convert the master production

schedule into a detailed schedule for

raw materials and components

however the master production schedule

is one of the three sources of input

data on which mrp relies

the other two inputs are the bill of

material file and the inventory record

file

let's discuss these three inputs in

detail

master production schedule

the master production schedule is based

on an accurate estimation of demand for

the firm's product together with a

realistic assessment of its production

capacity

it is a list of what end products are to

be produced how many of each product has

to be produced and when the products are

likely to be ready for shipment

bill of material file

in order to compute the raw material and

component required for the end product

listed in the master production schedule

product structure must be known

this is specified by the bill of

materials which is a list of component

parts and sub-assemblies that make up

each product

putting all these assemblies together we

have the bill of materials file or bom

inventory record file

it is mandatory in mrp to have accurate

current data on inventory status

this is accomplished by utilizing a

computerized inventory system that

maintains the inventory record file

an explanation of the lead time for the

raw material components and assemblies

must be established in the inventory

record file

process of material requirement planning

the mrp process can be split into 4

basic steps

step 1.

estimating demand and the materials

required to meet it

the initial step of the mrp process is

figuring out customer demand and the

requirements to meet it

utilizing the bill of materials which is

simply a list of raw materials

assemblies and components needed to

manufacture an end product

mrp breaks down demand into specific raw

materials and components

step 2

check demand against inventory and

allocate resources

this step involves checking demand

against what you already have in

inventory

then nmrp distributes resources

accordingly

in other words the mrp allocates

inventory into the exact areas it is

called for

step 3

production scheduling

the next step in the process is simply

to calculate the time and labor required

to complete manufacturing

it also sets a deadline

4.

monitor the process

the final step of the process is simply

to monitor it for any issues

the mrp can automatically alert managers

of any delays and even suggest

contingency plans in order to meet build

deadlines

mrp output reports

material requirement planning generates

a variety of output that can be used in

the planning and management of plant

operations

these outputs include

primary outputs

order release notice to place orders

that have been planned in the mrp

process

rescheduling or cancellation notices

showing rescheduling or cancellation of

open orders because of a change in the

master schedule

reports on inventory status

secondary outputs

performance report of various types

indicating costs item usage actual

versus planned lead time etc

expectation reports showing deviation

from schedule orders that are overdue

scrap and so on

inventory forecasts indicating projected

inventory levels in future periods

there are several advantages to the mrp

process and of course there are also

disadvantages to the mrp process

advantages of the material requirement

planning process

number one

assurance that materials and components

will be available when needed

2.

minimized inventory levels and costs

associated

3.

optimized inventory management

4.

reduced customer lead times

5.

increased manufacturing efficiency by

using accurate production planning and

scheduling to optimize the use of labor

and equipment

6.

increased labor productivity

7.

ensure capacity utilization

8.

increased overall customer satisfaction

now come to disadvantages of the mrp

process

1.

mrp systems can often be difficult and

expensive to implement

2.

lack of flexibility when it comes to the

production schedule

as mrp highly depends on having accurate

information about key inputs especially

demand inventory and production

if one or two inputs are inaccurate it

can magnify errors at later stages 3.

while mrp is designed to ensure adequate

inventory levels at the required times

companies can be tempted to hold more

inventory than is necessary thereby

increases inventory costs
