1. Job Production.

2. Batch Production .

3. Flow Production.

4. Group technology.

Types of production system are not necessarily

associated with any particular volume of

production.

Each type of production exhibits distinctcharacteristics and require different conditions for

its effective inception and working.

The choice of production system dictates the

organizational system and to a large extent, thelayout of the equipment.


4/17

Job, project or make complete , production is the

manufacture of the single complete unit by an

operator or group of operators.

Jobs may be on a small-scale involving little or no

technology or complex requiring lots of

technology.

e.g. Bridge building, dam construction, installingcapital plants in factory.


5/17

Production is simple and is relatively easy to get

hold of the skills and equipment required.

e.g. Hairdresser, tailoring, painting and decorating,plumbing and heating repairs in the home.

Characteristics:

1. Organization simple

2. Multiple operator skill

3. Low equipment utilization.


6/17

High technology jobs are much more complex and

difficult.

These jobs need to be very well project-managed

and require highly qualified and skilled workers.

e.g. Film production ,Large construction projects

(e.g. the Millennium Dome), Installing new

transport systems (e.g. trams in Sheffield )


7/17

Work on any product is divided into parts or

operations, and each operation is completed

throughout the whole batch before the next

operation is undertaken. Most common type of production system.

e.g. production of electronic instruments


8/17

1. Specialization of labour is possible.

2. Capital expenditure can be kept lower.

3. Organization and planning required is

considerable.

4. Production control department can produce most

benefits.

5.

Possibility of high plant utilization.6. Probability of poor material flow.

7. Value added slowly.


9/17

Flow has been defined as a production systemwhere the task is worked on continuously orwhere the processing of material is continuousand progressive.

Any fault affects all the stages in the productionline.

The aims of flow methods are:

- Improved work & material flow- Reduced need for labor skills- Added value / completed work faster.


10/17

1. There must be substantially constant demand.

2. The product and/or production tasks must be

standardized.

3. Materials used in production must be to

specification and delivered on time.

4. Each operation in the production flow must be

carefully defined - and recorded in detail.5. The output from each stage of the flow must

conform to quality standards.

e.g. manufacture of motor cars, chocolates and

televisions.


11/17

Continuous production:

This is a flow process.

e.g. Oil refining, Sheet glass making.

Jobbing production:Production carried out only against customers orders and notfor stock.

It does not indicate any particular type or method ofmanufacture.

Mass production:Mass production is nothing more than production on large scaleand such can be manufactured under either Job, Batch or Flowproduction methods.


12/17

It is based on a general principle that by grouping

similar problems, a single solution can be found to

a set of problems, thus saving time and effort.

The parts having similarities (Geometry,manufacturing process and/or function) are then

collected into families, and these families

manufactured on groups of associated machines.

The aim is to reduce work-in-progress andimprove delivery performance by reducing lead

times.


13/17

It is not necessary for each part of a part family tobe processed by every machine of corresponding

machine cell.

The manufacturing efficiencies are generally

increased by employing GT because the requiredoperations may be confined to only a small cell

and thus avoiding the need for transportation of

in-process parts.

Key to using group technology successfully is theability to identify readily items within the same

family.


14/17

Reduced unit set-up time.

Improvement in the effective use of the machines.

Reduction in transport distances.

Simpler management.

Improved labour efficiency resulting from

standardization.
