Break only possible with empty vehicle

[fbaierl]

Feature

I would like to request a feature to only schedule breaks at a time, where the respective vehicle is empty (load is empty).

Motivation

We work with public transport so we transport people. For obvious reasons, we cannot schedule a break at a time, where customers are still inside the vehicle, so this would be an essential feature for all use-cases, where people are transported (with time-windows).

API

For the API, this could be achieved by setting an additional parameter (e.g. while_transport) to the break input definition:

Key	Description
id	integer
time_windows	an array of time_window objects describing valid slots for break start
[while_transport]	a boolean, that is true if the break can happen while transporting load
[service]	break duration (defaults to 0)
[description]	a string describing this break

Implementation

As we previously discussed here, this might be possible with adapting TWRoute::is_valid_addition_for_tw.

Support

We would be willing to fund the implementation of this feature. Would it be possible to get a quote for this?

[jcoupey]

I've never encountered this constraint before but it definitely makes sense in a situation when dealing with passengers.

This would indeed require to adjust TWRoute::is_valid_addition_for_tw to discard invalid break positions when adding jobs/breaks along a modified route segment. The tricky part is that I think some validity checks should happen directly in the body of is_valid_addition_for_tw while others should take place in order_choice, which is called here from is_valid_addition_for_tw and embeds the whole logic of job vs break insertion decision. In particular, this would require to make sure that the adjustments to order_choice do not result in ruling out valid break insertions down the line.

[jcoupey]

Feature-wise, we could see the concept of "only possible with empty vehicle" as a special case of "only possible under X load" with X=[0...]. The latter constraint would not be harder since both require checking against the current vehicle load. The more generic version could prove useful in other situations, something along the line of "wait until the truck is half-empty before doing the break".

[fbaierl]

The more general approach would of course be great! Another possible use-case might be if some goods need to be transported as-fast-as-possible (e.g. Pizza) while other goods that are transported at the same time (normal parcels) don't mind waiting during the break.

I will try to assemble some examples of instances that should not happen (break with load > 0) in our case. Here is a first, small, example set:
