Feasibility studies

Question 1

What is the aim of lean manufacturing and who pioneered this?

Answer 1

minimise wasted time and materials, pioneered by Toyota

Question 2

Give 4 reasons why computer modelling is a central part of the lean manufacture

Answer 2

• simulation and planning of the assembly line, workstations etc.
• prediction of bottlenecks in production to help the planning of ‘buffer zones’ for temporary storage of partially completed work while slower tasks are undertaken
• cycle time calculation for production processes such as press forming
• “takt time’’ calculation of the rate of production to meet customer demand

Question 3

What is the equation for Takt time?

Answer 3

production time divided by customer demand

Question 4

What 2 categories of costs of production are calculated using spreadsheets?

Answer 4

direct costs

indirect costs e.g. factory lighting, rent

Question 5

What are feasibility studies?

Answer 5

use of various method to assess the particularity of a project

Question 6

True or false: factoring in the product selling price allows potential profits and feasibility of production to be assessed

Answer 6

true

Question 7

What aspects of production such as injection moulding use sophisticated computer modelling?

Answer 7

initial mould cost
size of moulding
number of units to be made
