Consider the following scenario and design the leanest production system possible.
You have a contract in which you have to make 1 billion mechanical parts.
The machine that is needed for the production is a semi-automatic one.
This category of machines does not need any supervision while they are machining and the only times a worker is needed are for Loading and Unloading actions.
For example microwave oven is a semi-automatic one.
For every single product:
The loading time = 0.5 min.
The unloading time = 0.5 min
Machining time = 3 min.
You have only one worker that can be assigned to any number of machines at a time.
Time of traveling between machines for the worker is 0
The cost of transporting a finished product to the costumer is 0 as well.
A machine can be rented for $1 per min while the worker’s wage is $1 per min.
The first priority is cost and the second priority is time.
Design the leanest production system possible.
