Is it possible to use the method we use to analyze the production system for analyzing a transport company?
![Page 3: Production System Analysis & Italian Transport Companies](https://reader034.fdocuments.in/reader034/viewer/2022042618/58a8583f1a28ab210b8b70db/html5/thumbnails/3.jpg)
Is it possible to assume a delivery good as a final Product (PF) of
Problem Tree?
![Page 4: Production System Analysis & Italian Transport Companies](https://reader034.fdocuments.in/reader034/viewer/2022042618/58a8583f1a28ab210b8b70db/html5/thumbnails/4.jpg)
In addition, how about the Elementary Operations (EO),
Resources, Production Functions,
Agents, Information patterns
and Organizational Chart!

The Problem Tree as a fundamental imagination
of what is happening in the production line
in our casefrom
NV = Non prepared vehicle
☟
FP = Satisfaction of the client by delivering her goods Pi in Ij

various situation,
here we will see a kind of

plant and enter in it
again. Maybe
because of different Point of
Loading or waiting for

You see the mass traffic of production functions behind the Resource 6

Do you remember who was responsible of 6th resource?
This means that the qualification of this resource is very important. So the manager or the controller should collaborate with the driver,
because efficiency and performance of this resource could seriously effect on the production line of transport & logistic system.

Organized transport companies, those are familiar to benefit form modern navigating systems (Real-time Optimization System),
have a Core Transport Network and an efficient work sequence cycles.
