Diagnostic results
The pyvrp.diagnostics module contains methods that help compute statistics from solutions.
- class RouteStatistics(distance: int, start_time: int, end_time: int, duration: int, timewarp: int, wait_time: int, service_time: int, num_stops: int, total_demand: int, fillrate: float, is_feasible: bool, is_empty: bool)
Object storing various route statistics.
- Attributes:
- distance
Total distance travelled over this route.
- start_time
Earliest starting time on this route, that is, the earliest time this route can leave the depot.
- end_time
Time at which the truck returns to the depot.
- duration
Total route duration, including waiting time.
- timewarp
Any time warp incurred along the route.
- wait_time
Time spent waiting on the route.
- service_time
Total service time on the route.
- num_stops
Number of clients visits along the route.
- total_demand
Total client demand on this route.
- fillrate
Capacity used by total client demand.
- is_feasible
Whether the route is load and time feasible.
- is_empty
Whether the route is empty.
- get_all_route_statistics(solution: Individual, data: ProblemData) List[RouteStatistics]
Returns route statistics for a set of routes. Empty routes are skipped.
- Parameters:
- solution
The solution individual for which to get all route statistics.
- data
Data instance corresponding to the route.
- Returns:
List[RouteStatistics]List of RouteStatistic objects with statistics for each route.
- get_route_statistics(data: ProblemData, route: List[int]) RouteStatistics
Returns statistics for a route.
- Parameters:
- data
Data instance corresponding to the route.
- route
Route (list of indices) to compute statistics for.
- Returns:
RouteStatisticsObject with statistics for the route.
