Problem Tree & Italian Transport Companies

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 case
 from
 
 NV = Non prepared vehicle


☟ FP = Satisfaction of the client by delivering her goods Pi in Ij

FP = Satisfactory of client by delivering his goods Pi to Ij

PF2 = Final unloading of goods

GE = Goods has entered to Delivery Point PF3 = Enter to the plant GA = Goods (vehicle) has arrived to the plant

PF5 = Driving GA = Goods (vehicle) has exited from the plant

PF4 = Exit from the plant Doc. = Transport’s Documents has taken

PF6 = Documents has taken

L = Goods has Loaded

PF1 = Loading operation

VE = Vehicle has entered to client’s plant

PF3 = Enter to the plant VA = Vehicle has arrived to the plant

PF5 = Driving

VX = Vehicle has exited from the plant PF4 = Exit from the plant

VR = Vehicle is ready to start working

PF7 = Vehicle preparing

NV = Non prepared vehicle for work

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.

GA = Goods (vehicle) has arrived to the plant

PF5 = Driving GA = Goods (vehicle) has exited from the plant

PF4 = Exit from the plant Doc. = Transport’s Documents has taken

PF6 = Documents has taken

L = Goods has Loaded

PF1 = Loading operation

VE = Vehicle has entered to client’s plant

PF3 = Enter to the plant VA = Vehicle has arrived to the plant

PF5 = Driving

VX = Vehicle has exited from the plant

LA MAMMA !!!

List of the steps to resolve 1st Exercise! FP = Satisfactory of client by delivering his goods Pi to Ij

PF2 = Final unloading of goods

1. Read the Problem Tree carefully! GE = Goods has entered to Delivery Point

PF3 = Enter to the plant

2. Graph of Components (that represent the Elementary Operations)! GA = Goods (vehicle) has arrived to the plant

PF5 = Driving

3. The Table of Paths to find the number of PHASES! GA = Goods (vehicle) has exited from the plant

4. Represent the diagram of EO’s! PF4 = Exit from the plant

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.

5. Identify the Production Functions! Doc. = Transport’s Documents has taken

6. Represent the Work Sequence!

PF6 = Documents has taken

L = Goods has Loaded

PF1 = Loading operation

7. Graph of Production Functions! 8. Table and Graph of Resources! VE = Vehicle has entered to client’s plant

PF3 = Enter to the plant

9. Scheme of Layout, evaluation of DM’s and Critical Points!! VA = Vehicle has arrived to the plant

PF5 = Driving

10. Information Pattern and Organizational Chart
 - Study the table of Agents
 VX = Vehicle has exited from the plant

PF4 = Exit from the plant

- Represent the type of connections according to the table of Agents VR = Vehicle is ready to start working

PF7 = Vehicle preparing

NV = Non prepared vehicle for work

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

9

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 ?!!

MS What 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

SOME CONSTRAINTS ABOUT HOURS OF RESTING •

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

•

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:

KPI

MS

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 = MS Reach Customer Wait for Unloading etc.

10%

Driving L + tack doc.

Wait for Loading UL + tack doc.

4% 6% 24%

22% 11% 23%

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.
