I want to publish a Vehicle Routing Problem(VRP) service as geoprocessing service. For that i have created a model but the problem is how to add number of vehicle/ routes to my model?

[AnuranjanaNand]

there is problem in building a model to run a vehicle routing problem. (the model from the arc tool box --> network analyst server: the inbuilt model for VRP.) the above model is not accepting  routes input and providing with a error : invalid input.

how to overcome this situation?
