This document presents an overview of different types of manufacturing processes:
1) Continuous production operates constantly without interruptions to produce large volumes of standardized products. Mass production also aims to produce high volumes of standardized goods through flow lines.
2) Intermittent production allows for flexibility in producing different products using the same line. Batch production manufactures identical articles in batches on a regular or irregular schedule.
3) Job and project production are for low volumes of complex, customized products according to customer specifications within set timeframes and costs. They require highly skilled workers due to complexity.
2. Production System
A production system can be defined as a
transformation system in which saleable
product or service is created by working
upon a set of inputs.
Inputs are usually in the form of men,
machine, material, money, etc.
Input
Men
Machine
Material
Money

&
Services.
4. CONTINUOUS PRODUCTION
Continuous means something that operates
constantly without any irregularities and frequent
halts.
SPECIAL FEATURES
In this type of production, goods are produced on
large volume based on the demand forecasting.
Plant facilities are fully engaged and sequencing
of operations is there.
Special purpose automated machines are used to
perform operations.
Products are standardized and identical in nature.
Absence of maintenance may interrupt whole
process
5. MASS PRODUCTION
Also known as repetitive production
Mass production is associated with flow
lines or assembly lines.
Mass production produces large volume of
standardized products for mass market.
Goods are manufactured either at a single
operation or at a series of continuous
manufacturing.
Examples : plastic goods, televisions,
radio, home appliances, etc.
6. PROCESS PRODUCTION
Process production is categorized by the
manufacturing of single product.
The flexibility of such plant is almost zero
as only one type of product can be
produced in such type of plant.
Special purpose machines and equipments
are used.
Material handling is highly mechanised.
Examples are refineries, petrol, kerosine,
sugar, etc.
7. CONTINUOUS PRODUCTION
ADVANTAGES
There is no rest period
between operations;
W.I.P is at minimum.
Material handling is
minimum.
Any weakness in
process is
immediately
highlightened.
Material can be
planned accurately.
DISADVANTAGES
The workers feel
boredom and
frustrated.
There is factor of low
morale among
employees.
Poor quality could be
there due to boredom
of workers.
8. INTERMITTENT PRODUCTION
A manufacturing method of producing
several different products using the same
production line.
Special features
Production system is flexible.
Design of product as well as system could
be changed according to the need.
General purpose machines and
equipments are used
Volume of production is small.
Production is as per customer orders.
9. BATCH PRODUCTION
Batch production is the manufacturing of
number of identical articles either to meet
specific orders or to meet continuous
demand.
Batch production is carried out on regular
or irregular time intervals.
It is also known as Quality production.
Breakdown of machine do not affect the
whole production.
Example of this type of production is
pharmaceuticals, paint industry, bakeries,
etc.
10. JOB PRODUCTION
Production is done for one or few quantity
of products as per customer’s specification
within prefixed time and cost.
Products are of variety and volume of
production is low.
Workers are highly skilled due to its
complexity in production.
This type of production is highly flexible
Examples are repair shops, tailor shops,
hair dressers, etc.
11. PROJECT PRODUCTION
Project is a temporary job having defined
beginning and end undertaken to meet
unique goals and objectives.
Highly complex in nature.
All operations are carried out in a fixed
position layout as product remains fixed
and manpower and facilities put work on it.
PERT/CPM can be used for planning and
control.
Examples are ships, locomotives air craft,
roads, buildings, spacecrafts, etc.
12. INTERMITTENT PRODUCTION
Advantages
Flexibility
High profit margins
General purpose
machines and
equipments are
used.
It meets specific
requirements.
Disadvantages
Requires highly
skilled and trained
workers.
High investment.
