Hi Jay Yes I have tried loading them into the the 'Route' solver, and yes it does generate a route. However, I cannot get an optimized route this way. If i check the box to optimize the route order then the process freezes when over 400 points are used... If I do not check the optimize route box then I can solve over 10,000 points.... (but this is only presenting a route between the points in the attribute table without sorting them into a good sequence) I think this process would work if I could find a way to organise the points into the correct sequence before running the 'Route' solver...

One more thing that my be relavent is that i've not given a sequence... when working with the network analyst 'route' i found that sequence was basically the key to speed... I imagine this is because Network Analyst must then apply either the Dijiskas or Tabu algorithm to sort the points.

Hi Jay My network has 3185 edges. I've re-run everything but finding the process is stalling at 33%. I've let it run, and although its not crashing, its not completing either. I've tried with 400 points and 2634 points with the same result. The closest I'm getting is by reducing the capacity to around 50. When I do this the process runs right through... it sticks at 33% for about 1 minute, then at 66% for 15minutes, then completes. Any ideas would be appreciated... I'm not really sure what to try next I've already tried limiting the prcess to just MON1 & MON2 but am finding similar problems.... it works when the capacity is at 50, not when its at 500 [ATTACH=CONFIG]25562[/ATTACH] POSITIVE NOTES.... The routes are now recording total travel time and distance. I am also getting the total culumative cost. THINGS IVE NOT DONE YET: The blue polygon that you can hopfully see in the distance will become my routes zone layer once ive figured out how to get the whole process to run through. Ive also not yet managed to run the calculate locations tool into my point data. I will do this once the routes are running a bit easier

Running ArcGIS 10 and the machine has 16.0 GB RAM I'm sure that should be upto the task, I must be making a mistake somewhere. I'm rebuilding my network at the moment with time and distance costs. How many stops should the VPR be able to handle? approximately? I have 28,000 dwellings, and im surrently using corner numbers to reduce the density, but that has given me no way to utilise the capacity function... Regards, Lucas

Thanks for the help guys I've been working through your suggestions and have a few more questions. I'm finding that i cannot solve for more than 300 points without a crash. 1.Is there any way for me to break the problem into smaller parts, save the routes and then join them together? And if there is how? 2.Jay mentioned that you can adjust the route at the end of the process... how can I do this? it seems that you would need to re-run the solver to change the allocated route? Thanks again, Lucas

Hello I've been asked to provide an optimized routing soloution for the rubbish and recycling trucks in my district. I do not have access to the Routesmart extension so I've had to work with the Network Analyst 'Route' or 'Vehicle Routing Soloution' options. So far I've had most success with the 'Route' option by manually creating polygons of the service areas, then intersecting this data to all of the city street corner house numbers, and then using the zones field from my manually created polygons to organise the days collections. This is essentially a table based system of solving the problem. The problems are really starting to pile up though. My routes are certainly not the most efficient. I've lost all of my truck capacity functions, and although I am capable of routing trucks from the depot to the route, to the recycling centre, back to the route and then onto the depot again, I have no way of doing the drop offs intelligently. That is to say I lost most of the benifit of optimizing a route. Does anyone have a soloution or any ideas? p.s I have used the city street corners to try and remove some of the density from the problem. It would be more ideal to be able to use all of the street addresses as i would be able to calculate capacity more effectively... Any thoughts would be appreciated... Regards, Lucas
