Operations Flashcards
Production
The process of converting inputs such as land, labour and capital into sale-able goods
Productivity
A measure of the efficiency of inputs used in the production process
Calculating productivity
Total output/ Number of production workers
Improving labour productivity
- Increasing output with same number of workers
- Keeping output at the same level but with fewer workers
Inventories
The stock of raw materials, work-in progress and finished goods held by a business
Lean production
The production of goods and services with the minimum waste of resources
Advantages of Lean production
- New products can be brought to the market quicker
- Quality is improved
- Wastage of time and resources is reduced or eliminated
- Unit costs are reduced
JIT inventory control
No inventories are held by the business. Raw materials arrive from suppliers just as they are needed for the production process.
Eval of JIT
:) Reduces costs
:( Businesses need to communicate very well with suppliers
:( Workers and the machinery used in production must be flexible
Job production
The production of items one at a time
Batch production
The production of goods in batches. Each batch passes through one stage of production before moving on to the next
Flow production
The production of very large quantities of identical goods using a continuously moving process
Eval of job production
:) Unique, high quality products are produced
:( Uses skilled labour rather than machinery so selling prices are higher
Eval of batch production
:) Larger numbers are made so unit costs are lower
:( Workers are less motivated because the work becomes repetitive
Eval of flow production
:) More capital intensive than job or batch production so lower labour costs
:( Requires large capital investment in production line technology
