AND CONTROL (PPC)
PRODUCTION: that transformation of raw
materials to finished goods.
PLANNING: looks ahead, anticipates possible
difficulties and decides in advance as to howthe
production, best, be carried out.
CONTROL: phase makes sure that the
programmed production is constantly maintained.
Main Functions of Production
Planning & Control Department
Production Planning & Control
Production planning and Control
• Production planning is an
activity that is performed before
the actual production process
• It involves determining
• the schedule of production,
• sequence of operations,
• economic batch quantities, and
• the dispatching priorities for
sequencing of jobs.
• Production control is mainly
involved in implementing
production schedules and is the
corollary to short-term
production planning or
• It includes
• initiating production,
• dispatching items,
• progressing and
• then finally reporting back to
Objectives of production planning and control
• 1. To plan production facilities in the best possible manner along with
the proper systematic planning of production activities.
• 2. Providing men, machines, materials etc. of right quality, quantity
and also providing them at the right time forms a very important
• 3. To inform, about the difficulties or the various awkward positions
expected to crop up later, to the management beforehand.
System is a whose function is to convert a
set of inputs into a set of desired outputs.
Given a specific process planning, process
technologies and production conditions
predetermine varieties, quantities, qualitiy,and
scheduled of products to be produced according
to market demand of products..
And Where we are-----------?
Long Range Planning; is done annually and
focus on a planninghorizon greater than one year.
Medium Range Planning; usually covers a
period from 6 months to 18 months, with monthly
or sometimes quarterly time increments.
Short Range Planning; covers a period fromone
day or less to six months, with weekly time
That may be defined as the technique of
foreseeing every step in a long series ofseperate
Each step to be taken at the right time, and in the
right place and each operation to be performed in

The main aim of routing; determine the best and
cheapest sequence of operations and to ensurethat
this sequence is strictly followed.
Routing procedure involves following different
An analysis of the article to determine whatto
make and what to buy
To determine the quality and type ofmaterial
Determining the manufacturing operations and
An analysis of cost of the article
Determination of scrap factors
It mainly concerns with time element and
priorities of a job.
The pattern of scheduling differs from one jobto
another which is explained asbelow:
Defined as the relationship between loadand
capacity, so as to assign the work for the
Capacity: the time available for work atwork
centres expressed in machine hours or in man
Load: to assign work to the capacity availableat
particular work centres.
It includes the assignment of the work tothe
operators at their machines or work places.
Loading determines; who will do the workas
routing determines; where and scheduling
determines; when it shall be done.
