Overview

One may further constrain the frequency and duration of the breaks specified above, by enforcing a minimum break frequency, such as "There must be a break of at least 1 hour every 12 hours". Assuming that this can be interpreted as "Within any sliding time window of 12h, there must be at least one break of at least one hour", that example would translate to the following FrequencyConstraint:

{
   min_break_duration { seconds: 3600 }         # 1 hour.
   max_inter_break_duration { seconds: 39600 }  # 11 hours (12 - 1 = 11).
}

The timing and duration of the breaks in the solution will respect all such constraints, in addition to the time windows and minimum durations already specified in the BreakRequest.

A FrequencyConstraint may in practice apply to non-consecutive breaks. For example, the following schedule honors the "1h every 12h" example:

  04:00 vehicle start
   .. performing travel and visits ..
  09:00 1 hour break
  10:00 end of the break
   .. performing travel and visits ..
  12:00 20-min lunch break
  12:20 end of the break
   .. performing travel and visits ..
  21:00 1 hour break
  22:00 end of the break
   .. performing travel and visits ..
  23:59 vehicle end

Instance Attribute Details

#max_inter_break_duration ⇒ `::Google::Protobuf::Duration`

Returns Required. Maximum allowed span of any interval of time in the route that does not include at least partially a break of duration >= min_break_duration. Must be positive.

Returns:

(::Google::Protobuf::Duration) —
Required. Maximum allowed span of any interval of time in the route that does not include at least partially a break of duration >= min_break_duration. Must be positive.
