Red Cross Annual Appeal
2004 (2200)
Locate collectors, assign streets and postcode for sorted bulk mailing
Built roads as single arcs using a route system
Exclude roads allocated by hand
Spatial join in ArcView 3.2 (avenue scripts)
Lowest ID first to resolve ties
Exclude allocated streets and repeat
2004 - Nearest whole streetcontinued manual start
Double collector numbers
2004 (2200) 2005 (4200)
Do you really know your own location address??
250 location errors, 150 had to be rung up again!
Geocoding AddressParse, AddressMatch
SpatialOrder - Peano Curve Numbering
Allocate (resources on arcs to centres and routes)
ArcInfo Network Module
2005 - Allocate 50 houses per collector
- nearest, contiguous, street segments - to pack them in where dense - to reduce the variability - to be clever, to prove that GIS…
Still needed to choose 1000’s of centres
First pass 5 min, time halved each pass
After 9 passes, still 250 “spare” collectors
Allocate
Reduce min capacity
Increase start distance
Give a “second chance”
Tune for dense areas
Rounding up and down to nearest intersection
Collectors unable to stop mid-segment
Many cannot, or would not, read a map
AML “Model Builder”
• 69 “Tools” in Model• 500 lines of AML• Adaptive iteration• Output from one
tool not able to be Input to next, needed low-level hacking
• Two days available
Mail-merge with a map
4000 maps/ hour, mail merge 3.5GB/1000 letters
“Spares” to be allocated by hand…but ran out of
time
Accepted fault and reprinted letters
because of my postcode error
Collection Week
Queries overwhelmed the help desk, even with maps
Added myself as a collector to experience it
Own street was the best part
Addresses underestimate the dwellings by 30%
Results Analysis
Amount per collector (av $76) Distance from address
Next Year, Version 3…
• 2004 increased by 50% to $150,000• 2005 increased by 40% to $211,000• Collector preferences!• next year…
– Improve choosing collectors– Better reference layers– Spread collectors better– More time for mail-out
