Unit 13: Production Planning and Control

(a) Product Variety and Production Quantity Notes
Logistic Problems:
For Job Shop Production (an intermittent Process):

In this case, many different types of products are made and each product is made in low
quantities. The products are often complex, consisting of many components each of which
must be processed through multiple operations.
Solving the logistics problems in such a plant requires detailed planning scheduling and
coordinating of large numbers of different components and processing steps for many
different products.

Whereas for mass production (Continuous Products Process), in which a single or more
products are made in large quantities.

Did u know? The logistics problems in Mass Production are simple if the products are
simple and for large component in case of an assembly line of automobiles or household
appliances and the facility is organised as a product line.
The logistic problem in operating such a case to get each component to be at right
workstation at the right time so that it can be assembled to the product as it passes through
the station.
(b) Planning Function: To distinguish between these two extremes in terms of the issues in
production planning and control, we can say that the Planning function is emphasised in
a job shop, whereas the control function is emphasised in the mass production of assembled
products. There are many variations between these extremes, with accompanying
differences in the way production planning and control are implemented.

Task Find out the similarities and dissimilarities between the production planning system
of a car manufacturing company and a FMCG company.

13.3 Aggregate Planning Defined

Aggregate Planning may be defined as ‘Intermediate Planning’ which is normally done for a
period of up to one year’s time. The word ‘Aggregate’ symbolises that the planning is done at
the broadest level. The details of the individual product requirements and the detailed scheduling
of various resources (men/machines) and other facilities is normally not done and left to the
individual at lower level to carry out the same.
