From the management point of view , the key
objectives of Material Management are :
•Tobuyatthelowestprice,consistentwithdesiredquality
andservice
•Tomaintainahighinventoryturnover,byreducingexcess

Scope of Materials Management:
Basically, under its scope are :
•emphasis onthe acquisition aspect
•inventory control and stores management
•material logistics, movement control and handling
aspect
•purchasing, supply , transportation , materials
handling etc
•supply management or logistics management
•all the interrelated activities concerned with materials

PURCHASES OF PRODUCTIVE MATERIALS:
POURCHASE DEPARTMENT:
The purchasing department is responsible to:
•Receive purchase requisitions for materials, supplies,
and equipment;
•Keep informed concerning sources of supply, prices
and shipping and delivery schedules;
•Prepare and place purchase orders, and
•Arrange the purchasing, the receiving, and the
accounting departments.

Purchasing Forms
PurchaseRequisition:
Thepurchaserequisitionoriginateswith:
•Astoresorwarehouseclerk,whoobservesthatthe

•Amaterialsledgerclerk,whomayberesponsiblefor

17. Material Management System
•A works manager, who foresees the need for
materials or unusual quantities
•A research, engineering or other department
employee or supervisor who needs materials or
supplies of special nature, or
•An information system that has been installed or
developed to produce replenishment advice for the
purchasing department.

Receiving:
The fundamentals of the receiving department
are to:
•Unload and unpack incoming materials,
•Check quantities received against the shipper’s
packing list,
•Identifying goods received with descriptions on the
purchase order,

21. Material Management System
Receiving:
•Notifying the purchasing department of
discrepancies disco…….,
•Arrange for inspection when necessary,
•Notifying the traffic department and the
purchasing department of any damage in transit,
and
•Route accepted materials to the appropriate
factory location.

Bill of Materials:
The bill materials, a kind of master requisition, are a
printed or duplicated form that lists all materials and
parts necessary for a typical job or production run.
Time is saved and efficiency is promoted through the
use of a bill of materials. When a job or production
run is started, all the materials listed on the bill of
materials are sent to the factory are issued on a pre
arranged time schedule.

Other Materials Costing Method:
Besides LIFO, FIFO & Average Cost methods of
costing materials units into work in process, various
other methods exist:
•Market Price at Date of Issue or Last Purchase
Price:
•Standard Cost:

42. Material Management System
MATERIAL COSTING METHODS
•Market Price at Date of Issue or Last Purchase
Price:
Materials precisely standardized and traded on
commodity exchanges such as cotton, wheat, copper,
or crude oil, are sometimes costedin to production at
the quoted price at the date of issue. In effect, this
production substitute replacement cost for experienced
or consumed cost and has the virtue of changing
materials into production at a correct and significant
cost.

MATERIAL PLANNING AND CONTROL
•Control Principles:
Inventory control systems and techniques should be
based on the following principles:
•Inventoryiscreatedbypurchasing:
oMaterialsandparts,and
oAdditionallaborandoverheadtoprocessthe
materialsintofinishedgoods.
•Inventoryisreducedthroughsalesandspoilage.
•Accuratesalesandproductionscheduleforecastsare
essentialforefficientpurchasing,handling,and

50. Material Management System
MATERIAL PLANNING AND CONTROL
•Control Principles:
•Management policies, which attempt to balance size and
diversity of inventory, are the greatest factor in
determining inventory investment.
•Ordering materials is a response to forecasts, scheduling
production controls inventory.
•Inventory records alone do not achieve inventory control.
•Control is comparative and relative, not absolute. It is
exercised by people with varying experience and
judgment.
•Rules and procedures guide these individuals in making
evaluations and decisions.

•Packing
•Traffic
•Shipping
•Statistical Analysis
MATERIAL PLANNING AND CONTROL
Organizing for Materials Control:
A materials management department may include
some or all of the following sections:
•Planning and
Scheduling
•Purchasing
•Receiving
•Inspection
•Stores
•Materials Handling

52. Material Management System
MATERIAL PLANNING AND CONTROL
Material Control Methods:
Materials control methods differ primarily in the care
and cost expanded. Critical items and high-value items
require greater attention than do low-value items.
Control methods include the:
•Order cycling,
•The min-max, and
•Just-in-time
