Hello,
is there a solution for this problem, I am dealing with similar thing - Micro routing for recyclables collection, and I also have to use Network Analyst.
I have two zones for collection 816 and 802 (nodes) bins.
After clicking solve the algorithm runs well. For 816 nodes it takes an hour, but after that time I get a sort of solution. I have outputs in route properties (TotalOrderServiceTime, TotalTravelTime...), but there is no route on the map. I can see only the sequence of orders.
In addition two error appears:
Error: "Failure while working with internal route problem instance"
Error: "A column was specified that does not exist."
I think I did sometning wrong with my network dataset or attributes but still cannot find out what it is.
Any suggestions?
Anyway the sequence of orders I can see is not the optimal one because some nodes are skipped and the truck returrns for them later.
1. Is this caused by that the solver is not designed for such a task?
2. I started experimenting and this anomalous sequencing occures on smaller sets too. Now It seems to me that it depens on the number of nodes per route, but also on the exact area in the network and set of nodes that is chosen. Sometimes it helps to use a seedpoint sometimes not.
Is there some exact threshold how many nodes the solver should be capable to do without this sort of error?
I would need 255 nodes for each of my zones to solve it by placing one point along the mid point of an edge.
