2.21 Unassigned Orders

If the solution generated by the optimiser contains any orders that are not assigned to a vehicle, then the optimiser will carry out an analysis to try to determine the reasons for those orders not being assigned.

Examples of such reasons include:

• Orders not being compatible with any of the vehicles in the fleet.
• Orders have a weight or volume demand that exceeds the maximum vehicle weight or volume capacity of any vehicle in the fleet.
• Orders that need to be picked up or delivered before the start time of any of the vehicles in the fleet.
• Orders that require more time to complete than the maximum working time of any vehicle in the fleet.

Note that the focus of the analysis is on finding reasons that are likely to indicate errors or omissions in the input data. It is possible that the analysis will not find any definite reason for an order being unassigned.
