DEFINITIONS
PRODUCTION:-
Transformation of raw materials to finished goods
PRODUCTION MANAGEMENT:-
Application of management principles to the process of production in an industry
to produce desired goods in economical manner by co-ordinating the efforts of
men, material & machine.
4

PRODUCTION PLANNING:-
It is a technique which helps in planning & scheduling the work in the
manufacturing plant to obtain the desired quality of products with optimum
efficiency & at minimum cost.
PRODUCTION CONTROL:-
It ensures that the work is being done according to the plan
5

PRODUCTION PLANNING
This phase includes a sequence of ideas to perform a task in an orderly manner by the
utilization of available manufacturing facilities.

A. PROCESS PLANNING
Process planning can be defined as the preparation of detailed plans for the
process required to manufacture a product as each manufacturing process
consists of numerous operations.
PROCESS PLANNING REQUIRES
 Quantity of work to be done
 Product specifications
 Sequence of operations to be performed
 Time required for each operation
 Availability of manufacturing facilities
8

STEPS INVOLVED IN PROCESS PLANNING
Process
selection
Selection
of raw
material
Selection
of
machinery
parts
Process
layout
Time
setup &
standard
operation
time
Documen
tation
9

a) PROCESS SELECTION:-
 The operations selected for a particular process should be most economical
 Should satisfy the product specifications
 Selection mainly depends upon quality, quantity, time period & machines
available
b) SELECTION OF RAW MATERIALS:-
 Should meet quality standards
 Should show chemical compatibility
10

c) SELECTION OF MACHINERY PARTS:-
Proper selection of machinery attachments like inspection gauges, jigs, etc., is
necessary for the smooth functioning of machines. This helps in reducing the costs
& duration of production & results in high output.
d) PROCESS LAYOUT:-
It describes every step of operation as well as the sequence in which each
operation is to be carried out.
11

e) TIME SETUP & STANDARD OPERATION TIME:-
They should be established to complete the production within the time.
f) DOCUMENTATION:-
Process planning should be clearly summarized in documents such as
operation & route sheets.
12

B. ROUTING
 Routing is the process of determining the sequence of operations to be carried out.
 Determines the path for flow of work right from the selection of raw materials until
the completion of production of finished goods.
 Routing is summarized in route sheets. Prepared sheets are then dispatched to the
production department.
Route sheets summarizes processes like
 Description of operations
 Sequence of operations
 Type of machinery
 Setup time
 Operation time
13

C. SCHEDULING:-
 Scheduling concerns with time element. It refers to the time frame of all production
activities therefore scheduling is also known as time phase of loading.
OBJECTIVE:-
 To reduce the time of production
 To ensure that the products can be delivered before the due date
TECHNIQUES:-
 Master schedule
 Perpetual schedule
 Order schedule
14

a) MASTER SCHEDULE
 It contains information about all orders
 On receiving the orders they marked on the master schedule depending upon their
delivery date.
 It shows running production work & work ahead
15

b) PERPETUAL SCHEDULE
 It provides only a gross picture of the schedule.
 It involves
i. Preparation of load analysis sheet
ii. Preparation of Gantt load chart

Section Q
Section R
By knowing the weekly capacity of each section, the load against each section for a
certain number of weeks can be calculated and plotted on a Gantt Load Chart.
18

c) ORDER SCHEDULE
 Order schedule can be prepared by plotting dates vertically & facility horizontally
on the chart.
 Information required to prepare order schedule
 Name of machines & their set up times
 Total production time
 Date on which the order is to be completed

D. LOADING
 Loading is the relationship between load and capacity at work
place. It gives the information about number of machines, available,
their speed, capacity, capability. It helps to determine work load
and actual capacity of production.
21

PRODUCTION CONTROL
 Production control is the comparison between planning output
and output achieved.
STEPS INVOLVED IN PRODUCTION CONTROL:-
Dispatching Follow up
Cost
control
Quality
control
22

A. DISPATCHING
 It is the process of issuing orders & instructions to a particular operating
section of industry to start the processing of a given job on an assigned
machine in accordance with the previously planned sequence & time as
detailed in route sheets & schedule charts.
 Movement of materials to different work stations, movement of work from
one operation to another & supervision of work comes under this category.
23

B. FOLLOW UP
 It includes delays or deviations from the production plans
 It helps to reveal the defects in
 Routing
 Scheduling
 Loading
 Dispatching
 Misunderstanding of orders
24

C. COST CONTROL
 The total cost for the production of goods is determined & is compared with
standard cost to calculate the deviations as well as to follow corrective
action.
 It can be controlled by
 Reducing wastage
 Value analysis
 Inventory control
25

D. QUALITY CONTROL
 It helps to avoid & detects the defects in production process & isolation of
defective finished goods
 Finished products are inspected to ensure their acceptable quality
 Quality control techniques
 Statistical quality control
 Probability concept
 Poisson distribution
 Sampling inspection
