PAS/EDD has failed for 3 reasons:
1- The people who wrote the new loop detail often had no knowledge of the area they were writing. They completely failed to factor in issues such as natural boundaries, traffic patterns, residential vs. commercial stops, different road types, and the suitability (or lack thereof) of a particular type of package car for a certain area. What makes perfect sense when viewed via Google Earth from behind a desk does not always work in the real world.
2- PAS/EDD is focused solely on deliveries, and the system treats pickups as an afterthought. The reality is just the opposite. Good business sense requires us to design the entire route around being able to contain and service its pickups within a certain window of time.My deliveries might vary from day to day, but from 2:55 to 4:30 I have 32 pickups, 400 cubic feet of pickup volume, and an air drop with the airport shuttle to deal with.
3-PAS/EDD fails to account for the multitude of other metric-based hoops we are required to jump thru each day. The company wants us to follow trace 85%...it wants all pickups to be completed within 15 min of the scheduled time...it wants us to maintain an impossible SPORH...and in order to meet an impossible Stops Per Car number it will frequently eliminate entire routes right before start time and fling the volume from those routes onto the floor of whatever adjacent car the packages can be forced into in a desperate attempt to get the preloaders off of the clock and the packages out of the building. A loop detail that works perfectly for a 35 car lineup will fail miserably when 2 or 3 of those cars get arbitrarily eliminated at the last minute. PAS/EDD assumes optimum conditions when the reality is usually just the opposite.
