Detect best matching ressource (taxi / cab usecase)
Posted: Thu Oct 27, 2022 2:45 pm
Cheerio,
these days I've been challenged by several players with some performance topics. Their story was compareable and after some discussions with DEV I am super excited that Max dragged my attention to this approach outside the box.
Here are the constraints:
When I discussed the story with the partners based on different "dima driven approaches" we ran into different topics:
Here's the new approach / idea:
these days I've been challenged by several players with some performance topics. Their story was compareable and after some discussions with DEV I am super excited that Max dragged my attention to this approach outside the box.
Here are the constraints:
- Person needs a taxi at (x,y) as quick as possible
- Several taxi positions (x,y) are known
- Distances are compareably low, maybe preselected
- Both historical and live data are required
- Quality should match "ExactAtStart" behaviour
When I discussed the story with the partners based on different "dima driven approaches" we ran into different topics:
- XDima2.CreateDistanceMatrix doesn't support ExactAt..Consideration
Here's the new approach / idea:
- Instead of DIMA routings use a com.ptvgroup.xserver.xroute.MultiCoordinateOnRoadWaypoint !
- Supports both ExactAtStart / ExactAtArrival
- This approach seems to work fine if the single used wayoint is sufficient - because the interface already performed the choice for you!
- RED= 3 potential taxis waiting for a customer.
The closest one is picked. No info about the other two taxis returned.
