Route optimization can get complex when you consider all of the variables -
- Individual worker hours vs the job time windows allowed.
- Utilization of the worker (ie if they already have jobs booked)
- Length of the jobs vs hours in the day for the worker (or the workers shift hours).
- Geographic location of the jobs and travel time.
- Capacity of the worker vs capacity required for the jobs.
- Previously assigned jobs outside of the optimization selection that still have to be completed in the timeframe (so we need to allow for these).
So there are some things you should check when you receive optimization errors.
Don't worry we will be building smart error messages soon, so we can tell you the problem.
Below are the recommended things to check when you have a failed optimization, if these still provide no help, please email firstname.lastname@example.org.
1. Check the workers hours vs the time windows on the job/jobs. Also check your company working hours vs time windows. Or the specific workers shift hours, if their shift ends we may not be able to assign all jobs.
2. Check the jobs are not in any current open or pending optimization, as they will not show on the optimisation map if already in use in another optimisation.
3. Check the jobs have only one geo coded step, this is a current limitation of our optimisation. (more than one geo address per job).
4. Check the worker has the capacity (they do not have other jobs booked for this time)
5. Check the worker does not have other jobs in the timeframe that you cannot see, we will have to optimize around these, sometimes making the route look strange or non-optimal.
6. Check the duration of the jobs does not exceed the available hours in the run (ie 9 x 1 hour jobs will fail if allocated to an 8 hour worker shift)
7. If it takes 5 hours to drive between 2 jobs in an optimization, yet the driver is only allocated 4 hours in the time window, or is on a short shift on that day, the optimization will fail.
