Agenda
4
Business Background• Yodel is the new company name for the merged HDNL and DHL
Domestic businesses
• This took place in March 2010, with Yodel born two months later in
May
• The new business now has a share in the B2C and B2B markets
• Following the acquisition of the DHL Domestic business, Yodel had
two networks of drivers, tractor units and trailers to manage
5
Business Background• The combined Transport network meant that Yodel Transport had to
manage:
Trailers: c 1600
Trucks : c 600
Drivers: c 600
Fuel: 30m litres
Miles: 60m
• Both HDNL & DHL Domestic had legacy TMS systems in
place and investment was required to manage the fleet
6
Control Tower Implementation• Yodel reviewed the market for companies who could provide the following:
7
Control Tower Implementation• Yodel chose to use Isotrak, ESS and DPS software suppliers:
8
Network Rationalisation
• HDNL network
encompassed two national
Sort Centres
• DHL Domestic used a
Regional Sort network, with
5 Sort Centres in the UK
• Yodel Sort now has 4 Sort
Centres which sort nationally
9
C3 Implementation• A Yard Management solution was sought based on:
• Large volumes of traffic at the Sort Centres
• Sort Centres operating across more than 1 sites
• Improved management of client traffic
10
C3 Implementation - Wednesbury
• Yard space at Wednesbury was
tight, so a 2nd Yard was required
• Two sites managed by C3
• Simulation required to review Sort
capacities and shunters required
11
C3 Simulation – What was the purpose?
• The objective of the simulation was to understand a “day in the life” of Wednesbury :
• Determine how many shunters were needed to operate Wednesbury
• The workability of the expected operational flows
• Can the planned seal times be met based on different volumes and trailer arrival profiles
• Preparation for simulation:
• Initial discussion of requirements
• Provision of data, storyboard, layouts, etc.
• Initial calibration runs of data, processes and key event process / timings
• Master run on standard volume and peak scenarios
• Interpretation of the stages, recalibration and iterative actions
12
C3 Simulation - Results• What the simulation did for Wednesbury was :
• Confirm the shunt numbers expected (originally calculated from base line manual estimates)
• Gave some pointers to the workability / changes to the expected operational flows
• Determine where changes were needed to the expected configuration
• What the simulation didn’t do for Wednesbury:
• Determine the key congestion bottlenecks (as seen by the Autologic movies / simulation)
• Take account of the emptying of MT trailers from the campus
• Truly determine the average “dead” time of doors following trailer removal
13
C3 Simulation
• Starting point: Yard is Setup for Start of Shift.
• Shipping doors: Empty trailers at doors (yellow).
• Receiving doors: Doors are empty waiting for loads.
14
C3 Simulation
• Receiving: Doors are full. Inbound trailers (red = National loads) are being parked, then automatically requested to doors.
• Shipping: Loaded trailers (green) are parked on both sides of building and gated out. Door Group requests empty trailers.
• Parking space on top filling up.
15
C3 Simulation
• Receiving:• Local loads (orange) are starting to arrive but parked.
Priority still Nationals.• Door group changed to prioritise local loads.
16
C3 Simulation
• Shipping:• Last wave. Release of full trailers.• Empty trailers are automatically requested to doors to
setup for next day.
17
C3 Simulation
• Simulation succeeded with 8 Shunters. All trailers were delivered by 03H00 AM.
• Stats show times where less resources could be used.
• The receiving and shipping schedule could also be adjusted to even out the shift and reduce rush/peak times.
18
• Improved visibility & control of all trailers in yard
• Ability to view all clients / load types and manage on priority, which has resulted
in dramatic reduction of client trailers being missed
• Ability to review history of trailers and movements
• Ability to analyse shunter tasks and performance
• Improved shunter productivity
• This has resulted in the removal of one AM shunter at Droitwich
• Wednesbury could not have operated without C3 system & it
provided flexibility during the transition period
