Exercise

Build your model: Run the model and examine results

You have created the assembly line environment and resources, the generators that produce aircraft orders, and the generator that characterizes the response of the assembly line given the processing times prescribed and limited resources available. The SimPy environment is stored in variable env.

Recall that your assembly sequence is defined in the figure below. The model time is in hours.

Airplane assembly sequence showing the different processes and limited shared resources.

Let's now run the model.
