I'm trying to implement time windows ou a route. The problem is a "Route" ploblem, and i have define may network with:

time parameter - "minutes"
Time window start - TWStart1
Time window end - TWEnd1

Filelds TWStart1 and TWEnd1 , type date

In options of the problem, define to use TimeWindows, and define start time

r. when solving, the solution have a start time, a end time, ignore time window on nodes or in lines, and have a violation time off zero.

Example.

Did you bring up the properties of the Route layer and turn on the "Use Start Time" and set a start time as well as turn on the "Use Time Windows" option?

Given your setup, the path should start at 8:00 AM, get to the middle stop a short while later and then depart at 9:00 AM and end the path at the third stop around 9:03 AM.
So can you double check that the ending time on the third stop is 9:03 and not 8:03
Also, can you bring up the properties of the middle stop and check that the time windows start and end are set to 9:00 AM and 10:00 AM?

Solving, arcgis simply ignore time windows.

Considers time of L1 and L2 - 2+2 min.
Considers time on node A2 - 10 min.

but don't wait to 9:30

Your screen shots for the attribute tables for bb show the TWStart1 and TWEnd1 are on the point feature class. BUT, do you load these values to the Stops when you do Load Locations? That is, open the attribute table for Stops and see if these values are set on the Stops TimeWindowsStart and TimeWindowsEnd columns. If they are not set then you need to reload your stops by maping these fields when you do load locations so that the values load in.

TimeWindowStart and TimeWindowEnd have a <Null> vallue.

"If they are not set then you need to reload your stops by maping these fields when you do load locations so that the values load in."

On layer properties, Network Locations, TimeWindowStart and TimeWindowEnd are load...

Your attached zip file cannot be downloaded as it says it's corrupt.

If the Stop properties are null, then you need re-load your Stops. But when you do that, on the
Load Locations dialog, make sure to map the time window fields and then open the Stops attribute table to see that the values have been set.

the download works fine to me.

I use winrar to compress the file in zip. Send in winrar mode.[ATTACH]2403[/ATTACH]
