material requirement planning or mrp
chapters i have discussed are what is
material requirements planning
functions of material requirement
planning inputs to material requirement
planning process of material requirement
planning mrp output reports advantages
of the material requirement planning and
disadvantages of the material
requirement planning
let's start the video
material requirements planning or mrp is
a computer-based inventory management
technique designed to improve
productivity for businesses
companies use material requirements
planning systems to ensure that
materials and components are available
in the right quantities and schedule
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
