Overview

Rules to generate time breaks for a vehicle (e.g. lunch breaks). A break is a contiguous period of time during which the vehicle remains idle at its current position and cannot perform any visit. A break may occur:

during the travel between two visits (which includes the time right before or right after a visit, but not in the middle of a visit), in which case it extends the corresponding transit time between the visits,
or before the vehicle start (the vehicle may not start in the middle of a break), in which case it does not affect the vehicle start time.
or after the vehicle end (ditto, with the vehicle end time).

class BreakRule
  include ::Google::Protobuf::MessageExts
  extend ::Google::Protobuf::MessageExts::ClassMethods

  # The sequence of breaks (i.e. their number and order) that apply to each
  # vehicle must be known beforehand. The repeated `BreakRequest`s define
  # that sequence, in the order in which they must occur. Their time windows
  # (`earliest_start_time` / `latest_start_time`) may overlap, but they must
  # be compatible with the order (this is checked).
  # @!attribute [rw] earliest_start_time
  #   @return [::Google::Protobuf::Timestamp]
  #     Required. Lower bound (inclusive) on the start of the break.
  # @!attribute [rw] latest_start_time
  #   @return [::Google::Protobuf::Timestamp]
  #     Required. Upper bound (inclusive) on the start of the break.
  # @!attribute [rw] min_duration
  #   @return [::Google::Protobuf::Duration]
  #     Required. Minimum duration of the break. Must be positive.
  class BreakRequest
    include ::Google::Protobuf::MessageExts
    extend ::Google::Protobuf::MessageExts::ClassMethods
  end

  # 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
  # ```
  # @!attribute [rw] min_break_duration
  #   @return [::Google::Protobuf::Duration]
  #     Required. Minimum break duration for this constraint. Nonnegative.
  #     See description of `FrequencyConstraint`.
  # @!attribute [rw] max_inter_break_duration
  #   @return [::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.
  class FrequencyConstraint
    include ::Google::Protobuf::MessageExts
    extend ::Google::Protobuf::MessageExts::ClassMethods
  end
end

#frequency_constraints ⇒ `::Array<::Google::Cloud::Optimization::V1::BreakRule::FrequencyConstraint>`

Returns Several FrequencyConstraint may apply. They must all be satisfied by the BreakRequests of this BreakRule. See FrequencyConstraint.
