2. Manufacturing Organisation
Manufacture
To make or process (a raw material) into a finished product, especially by a large scale industrial operation.
To make or process (a product), especially with industrial machines.
(Webster’s dictionary)

3. The Manufacturing System
Identification of the market need
Identification of the specification of the product
Construction of the prototype
Identification final specification of material and production processes to be used
identification and production of special tool requirements
planning of production methods
initialisation of sequences of operation
working out the plant layout and scheduling of work.

4. The Manufacturing System
If all the above steps have been properly implemented the product should now be able to be made to the customer’s requirements and product should be ready for on-time delivery.
Throughout the whole process it is essential to conduct the quality inspection procedures in order to maintain the quality of the product at an acceptable level.

6. Manufacturing Sub-systems
The manufacturing system consists of several sub-systems such as:
management system
production control system
financial control system and so on.
The idea of systems within systems is useful to control the processes efficiently

7. Manufacturing Sub-systems
Integrating The Effort
In a factory environment there are a lot of people involved in various activities.
Therefore, subjectivity and emotion are factors which highly influence on the output:
the personnel ambitions of individuals,
the different ways each person sees a situation
attitude
beliefs
personalities
Therefore, companies structure their organisation to minimise the human failings

Simplified simultaneous engineering event sequence
It is very important to maintain a good understanding about the various activities happening in each sub-system

10. Management by Objectives
In an organisation work done by each individual should directly contribute towards achieving the organisation’s ultimate goal.
MBO principles are:
Cascading of organizational goals and objectives,
Specific objectives for each member,
Participative decision making,
Explicit time period, and
Performance evaluation and feedback

14. Type of Manufacture Job Shop Ex: Ship making
A facility capable of producing a wide variety of products in very small volumes.
The production facility is general purpose and
Flexible enough to meet a variety of needs.
Ex: Ship making

15. Type of Manufacture Job Shop Characteristics Wide variety of products
Small lot sizes (one of a kind)
Done to customer orders or for finish goods
General purpose machines
Skilled workers
Low productivity
Functional grouping
Scheduling and process plan by route sheets

16. Type of Manufacture Batch Production
A process that does not have sufficient volume from a single product to fully use the facility.
Common components are made in volume and used to form products as needed
Ex: Cars, Pistons, Televisions etc.

17. Type of Manufacture Batch Process Characteristics Functional layout
Components manufactured in “large” batches and stored
Complicated scheduling / routing
