2 Production System Analysis & Italian Freight Transport Companies

3 Is it possible to use the method we use to analyze the production system for analyzing a transport company?

4 Is it possible to assume a delivery good as a final Product (PF) of Problem Tree?

5 In addition, how about the Elementary Operations (EO), Resources, Production Functions, Agents, Information patterns and Organizational Chart!

6 I INVITE YOU TO VISIT: TRANSPORT AND LOGISTICS - BREAKING DOWN THE BARRIERS

7 Assume that FP as satisfaction of client by delivering good Pi to Ij

8 IVECO OV dp

9 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

10 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 PF4 = Exit from the plant PF6 = Documents has taken PF1 = Loading operation PF3 = Enter to the plant GA = Goods (vehicle) has exited from the plant Doc. = Transport s Documents has taken L = Goods has Loaded VE = Vehicle has entered to client s plant VA = Vehicle has arrived to 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. 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

11 GA = Goods (vehicle) has arrived to the plant PF5 = Driving PF4 = Exit from the plant PF6 = Documents has taken PF1 = Loading operation PF3 = Enter to the plant GA = Goods (vehicle) has exited from the plant Doc. = Transport s Documents has taken L = Goods has Loaded VE = Vehicle has entered to client s plant VA = Vehicle has arrived to 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. PF5 = Driving VX = Vehicle has exited from the plant

20 List of the steps to resolve 1st Exercise! PF2 = Fina PF3 = Ente PF5 = Driv PF4 = Exit PF6 = Doc PF1 = Load PF3 = Ente PF5 = Driv PF4 = Exit 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 PF7 = Vehi

21 Graph of Components NV VR VX VA VE L DO EX GA GE PF

22 Table of Paths NV VR VX VA VE L DOC. EX GA GE PF 10 PHASES

23 Elementary Operations (EO s) & Phases

24 PF s & EO s PF s \ EO s

25 Functions & Phases F s/p s

26 Graph of Production Functions NV VR VX VA VE L DOC EX GA GE PF7 PF4 PF5 PF3 PF1 PF6 PF4 PF5 PF3 PF2 PF

27 Graph of Resources R s \ PF s You see the mass traffic of production functions behind the Resource 6

28 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.

29 Finally we arrived to the destination! The Work sequence and the layout of the system

33 KPI?!! MS What can not be measured CAN NOT be represent!

34 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

35 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 Obligated weekly hours of rest 45 hours - once minimum 24 hours

36 HOW HOURS OF DRIVING AND WORKING COULD BE MEASURED?!

37 CRONOTACHIGRAFO Analog Digital

38 Analog Setup time PF7 + + S ij S ji

39 Digital Setup time S ij = S ji

40 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

41 In addition, many specific traffic signs such as:

42 CONSTRAINTS ABOUT WEIGHT AND DIMENSION 40 = MAXIMUM FQ BATCH TOTAL WEIGHT 40 TONS

43 CONSTRAINTS ABOUT TRAFFIC POLICY AND CONTROL

44 SOME OTHER CONSTRAINTS ABOUT GENRE AND KIND OF GOODS OR MATERIAL

45 ADR

46 ADR S ij S ji

47 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.

48 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.

49 MS & Standard Transport Time

50 KPI = MS Reach Customer Driving Wait for Loading Wait for Unloading L + tack doc. UL + tack doc. etc. 10% 4% 6% 24% 22% 11% 23%

51 KPI = Compare your system with Competitor

52 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.
