Production System Analysis & Italian Freight
Transport Companies
Is it possible to use the method we use to analyze the production system for analyzing a transport company?
Is it possible to assume a delivery good as a final Product (PF) of
Problem Tree?
In addition, how about the Elementary Operations (EO),
Resources, Production Functions,
Agents, Information patterns
and Organizational Chart!
I INVITE YOU TO VISIT: TRANSPORT AND LOGISTICS - BREAKING DOWN THE BARRIERS
Assume that FP as satisfaction of client
by delivering good Pi to Ij

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
��
�
��
PF2 = Final unloading of goods
�
PF3 = Enter to the plant
��
�� � Doc. = Transport’s Documents has taken
� L = Goods has Loaded
FP = Satisfactory of client by delivering his goods Pi to Ij
GE = Goods has entered to Delivery Point
GA = Goods (vehicle) has arrived to the plant
PF5 = Driving
GA = Goods (vehicle) has exited from the plant
PF4 = Exit from the plant
PF6 = Documents has taken
PF1 = Loading operation
�� VA = Vehicle has arrived to the plant
�� VE = Vehicle has entered to client’s plant
PF3 = Enter to the plant
�� VX = Vehicle has exited from the plant
PF5 = Driving
��
VR = Vehicle is ready to start working
PF4 = Exit from the plant
NV = Non prepared vehicle for work
PF7 = Vehicle preparing
Sometime depends to
various situation,
here we will see a kind of
LOOP. Means that
vehicle have to exit of the
plant and enter in it
again. Maybe
because of different Point of
Loading or waiting for
receive Final Product that is not ready
yet etc.

List of the steps to resolve 1st Exercise!
1. Read the Problem Tree carefully!2. Graph of Components (that represent the Elementary Operations)!3. The Table of Paths to find the number of PHASES!4. Represent the diagram of EO’s!5. Identify the Production Functions!6. Represent the Work Sequence!7. Graph of Production Functions!8. Table and Graph of Resources!9. Scheme of Layout, evaluation of DM’s and Critical Points!!10. Information Pattern and Organizational Chart
- Study the table of Agents- Represent the type of connections according to the table of Agents

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.
Finally
we arrived to the destination!

KPI ?!!
MSWhat can not be measured CAN NOT be represent!
SOME CONSTRAINTS ABOUT HOURS OF WORKS AND DRIVE
• Total Daily hour of driving ⥴ 9 hours (2 times 10 h)
• Total Daily hour of all kind of work ⥴ 15 hours
• Total Weekly hour of working ⥴ 56 hours
• Total hour of work in two weeks ⥴ 90 hours
• Obligated daily hours of rest ⥲ 11 hours - max 3 times per week ( 9 + 3)
• Obligated daily break time ⥲ 45 min - after 4.5 hours of driving
• Obligated weekly hours of rest ⥲ 45 hours - once minimum 24 hours
SOME CONSTRAINTS ABOUT HOURS OF RESTING
HOW HOURS OF DRIVING AND WORKING COULD BE MEASURED ?!
• Analog
• Digital
CRONOTACHIGRAFO
• Analog • Setup time
++
• S ij ≠ S ji
PF7
• Digital • Setup time •S ij = S ji
SOME CONSTRAINTS ABOUT TRAFFIC
• Max speed in city center 50 km/h BUT most of the time maximum 30 km/h
• Max speed in regional ways 70 km/h
• Max speed in highways 80 km/h
• In addition, many specific traffic signs such as:
CONSTRAINTS ABOUT WEIGHT AND DIMENSION
MAXIMUM TOTAL WEIGHT
40 TONS
40 = +14 26
“FQ” BATCH
CONSTRAINTS ABOUT TRAFFIC POLICY AND CONTROL
SOME OTHER CONSTRAINTS ABOUT GENRE AND KIND OF GOODS OR MATERIAL

•S ij ≠ S ji

SO AFTER THAT SHORT INTRODUCTION ABOUT THE VARIES KIND OF CONSTRAINTS, THAT WE FACE THEM EVERY DAYS IN THE WORLD OF TRANSPORT & LOGISTICS LETS COME BACK AGAIN TO THE KPI CONCEPT:
7 th Scheduling problem,
Series Res.
Statistic analysis based on calculating time to reach the customers, time to loading, necessary time to drive the distance between the customer and delivery point etc.
MS & Standard Transport Time

KPI = Compare your system with Competitor
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.
