We are conducting a Vehicle Routing Problem in ModelBuilder. See below image. We can do it manually (in the network analysis window) but when we try to solve it in ModelBuilder, ArcGIS crashes. It is fine up until the solve section. All our inputs are feature classes created from a blank VRP manual menu.
In addition if we run the ModelBuilder up until solve, it works fine - it adds the routes, depots, and orders. But then when we try to solve it in the network analysis window, it crashes again.
Hi. It sounds like you have a reproducible crash. Sorry for your trouble! The best thing for you to do is to submit it to Esri Support, and they can work with you to resolve it or work around it, and also forward it on to the development team as appropriate: Esri Support Home
