4. INTRODUCTION
This chapter aims to give the reader an
overview of some of the most common forms
of manufacturing planning and control
techniques. It is not intended to examine
these systems in great depth but rather to
explain the basic principles of the various
approaches and explain some of the
terminology.

5. The following approaches will be covered:
• just-in-time;
•manufacturing resource planning (MRPII),
incorporating material requirements planning
(MRP);
•flexible fulfilment or, as it has come to be
known, postponement.

6. Push and pull systems
• A 'push' system of manufacturing is one where
goods are produced against the expectation of
demand. In other words, goods are not
produced specifically to order but are
produced against a forecast demand.

7. • A 'pull' system of manufacturing is one where
goods are only produced against known
customer orders. This is because only actual
orders from customers are being produced on
the production line. None of the goods are
being made to keep as finished product stocks
that may be sold at a later date.

8. Dependent and independent demand
• Dependent demand is created by the demand
for the constituent parts of the finished
product. In other words, because it is planned
to make a given finished product, this decision
triggers the demand for all the constituent
parts of that product.
Source: handbook onf logistics and distribution management
2006 hal. 183
9. • Independent demand is quite the opposite. In
this situation the schedulers do not have a
clear view of customer demand and are
therefore forced to forecast demand in the
best way they can

10. Cellular manufacturing
A lean method of producing similar products
using cells, or groups of team members,
workstations, or equipment, to facilitate
operations by eliminating setup and
unneeded costs between operations. Cells
might be designed for a specific process, part,
or a complete product. They are favorable for
single-piece and one-touch production
methods and in the office or the factory

11. JUST-IN-TIME
Just In Time (JIT) adalah suatu sistem produksi yang dirancang
untuk mendapatkan kualitas, menekan biaya, dan mencapai
waktu penyerahan seefisien mungkin dengan menghapus
seluruh
jenis
pemborosan
yang
terdapat
dalam proses produksi sehingga perusahaan mampu
menyerahkan produknya (baik barang maupun jasa) sesuai

13. Elimination of wasted time
Because only customers' orders are being
produced and the speed of the production
process is known, it is possible to synchronize
deliveries of raw materials to the end of the
production line (or to the precise point on the
production line in some cases) with little time
to spare before use. The whole purpose of this
exercise is to reduce the working capital used
in the overall manufacturing system.

14. Movement through the manufacturing
process
If materials move through the system in a
straight line it is reasonable to suppose that
the minimum distance has been covered. In
many manufacturing systems this is not
always possible. In fact it has been identified
in some manufacturing processes that
components and sub-assemblies are moved
around the factory in a very erratic pattern
before they all come together in the finished
product.

kanban is a card that is used to accommodate the needs of material
parts preformance operation process. Kanban system is an
information system which harmoniously controlling the production
of products in the quantities required at the time required in each
process (Monden, 2000).
In a JIT production system, kanban system is supported by the
following matters (Monden, 2000):
accelerate production
standardization of work
Setup time reduction
improvement activities
The design of the machine layout

16. Right first time
Quality problems in the form of scrapped or reworked
products are waste of the first order. The Japanese
developed several strategies to counter this problem. In
one case they built their factory with no area to store
scrap on the principle that having an area for scrap
encouraged its production. Quality circles were created,
where workers were allocated time specifically given over
to discussing quality issues and their elimination, the
target being zero defects. The philosophy of Kai zen, or
continuous improvement, was engendered as a working
culture in these organizations with support at the very
top. Systems of quality management such as total quality
management (TQM) and ISO 9000 seek to achieve the
same ends.

17. Finished product stocks
These stocks only contain goods produced to a
specific customer order. This too contributes
to a reduction in working capital. Because of
the needs of brevity it has only been possible
to skim the surface of the JIT philosophy.
Subjects such as the reduction of set-up and
change over times, team working and
empowerment, total productive maintenance,
levelled production schedules and many more
are arguably no less important.

18. MANUFACTURING RESOURCE PLANNING
(MRPII)
Although MRP pre-dates MRPII, it is easier to see MRP in the
context of MRPII rather than the other way round.
As the name implies, manufacturing resource planning deals with
more than simply production scheduling. Whilst the basic material
requirements planning system is incorporated into MRPII, the wider
system brings other activities into the picture. The objective is to
harmonize and control more of the activities within the production
plant. Areas outside an MRP system but included in an MRPII
system usually are:
• maintenance management;
• cost accounting;
• stock management;
• sales orders;
• procurement;
• personnel levels.

19. MATERIAL REQUIREMENTS PLANNING
(MRP)
Material requirements planning (MRP) is a computerbased inventory management system designed to
assist production managers in scheduling and placing
orders for items of dependent demand. Dependent
demand items are components of finished goods—
such as raw materials, component parts, and
subassemblies—for which the amount of inventory
needed depends on the level of production of the final
product. For example, in a plant that manufactured
bicycles, dependent demand inventory items might
include aluminum, tires, seats, and bike chains.

20. The master production schedule (MPS)
The MPS is a list of all the products or services
to be supplied within a specific period of time.
This period of time must be sufficiently long to
allow for the ordering and delivery of required
sub-assemblies and parts, as well as allowing
sufficient time for manufacturing the product
in question. The schedule may be made up of
forecast demand and actual known demand,
ie customers' orders
Source: handbook onf logistics and distribution management 2006 hal. 188
21. The bill of requirements
This is also referred to as the bill of materials (BOM). As
explained earlier, this will list all the sub-assemblies,
components and parts required in total to produce all
the goods listed in the master schedule. It will also
show the different levels at which these constituent
parts are put together in order to produce the finished
goods.
For example, the finished product may contain two
sub-assemblies that together complete the product
(see Figure 10.1).
This level is described as

management 2006 hal. 188
and
distribution
24. Opening stock
The master schedule and the bill of requirements
together form the framework of what is required
and when it is required, but two other factors must
be fed into the computer program at the same time.
The first of these will be the current level of
unallocated stocks of parts, components and subassemblies available for immediate use. There will
be in total larger stocks on hand but these will
already have been allocated to production via the
system and are therefore unavailable. This
information will, of course, modify any orders for
raw materials placed on suppliers.

25. FLEXIBLE FULFILMENT (POSTPONEMENT)
flexible fulfilment is a method of
manufacturing that attempts to delay the final
definition of a product to the last possible
stage in the supply chain - hence the popular
description of 'postponement' for this system.

27. THE EFFECTS ON DISTRIBUTION ACTIVITIES
The effects on distribution systems of just-in-time (JIT)
deliveries have led to more frequent deliveries of
smaller quantities to stringent delivery timetables. This
has had effects on vehicle fleets and scheduling as well
as developments in linked information systems
between manufacturer, supplier and transport
provider. Without these developments, JIT would be
virtually impossible. Distribution requirements
planning (DRP) systems were developed as a logical
extension of MRP systems. The principles have simply
been extended into a forward distribution planning
system.
