What is manufacturing?
Turning raw material into an end product
What is technology?
A piece of equipment
What are systems?
A group of resources
What are the 3 features of technology?
Operating capability - e.g. how large a product
Operating parameters - e.g. how fast cutter goes
Operating costs - e.g. how much energy consumed
What are the manufacturing system demands?
Increased product variety
Decreased product quantities
Increase in customer expectations
Decrease in time to market
Use new or better materials
Facilitate global production
What are physical structures?
Factories, equipment etc
What are virtual structures?
Management and control systems
What are the 5 P's of product and operation management?
What is the Product?
The interface between marketing and production
An agreement must be reached on performance and aesthetics, quality and reliability, quantity, selling price/production cost and delivery date/lead time
What is the Plant and what must it do?
Provides the tools to manufacture the product
It must match all needs and continue to do so
Must consider possible future demands, layout of buildings and facilities, performance and reliability of equipment, maintenance, safety and social responsibility
What is the Process?
The combination of people, skills, and equipment to manufacture the product
To optimise consider available capacity and skills, form of production, plant layout, safety and maintenance, costs
What is Programme/Resource Plan?
System which organises and controls the production operations.
Generates timetables and procedures for purchasing, production, maintenance, cash flow, storage and transport
What is People?
Link the virtual and physical structures
What is High Value Manufacturing (HVM)?
As the UK cannot compete on volume manufacturing, they try to compete by adding value to manufactured goods through technological improvement
What are the 3 key demands on HVM?
Reduced product quantities
Increased customer expectations
Use of new or better materials
How does HVM generate jobs?
It requires new processes to be developed and enables supply chains to be brought closer to production facilities
