Table 4

Results of testing on real data of a distribution company—divided delivery.

Instance code [8]	Number of customers	Algorithm solution cost	Number of available vehicles	Number of vehicles used	Number of depots	Comments
18012018	91	189.632	7	6	1	All constraints met. () Because of the SD constraint, vehicle J92-T-826, which can only service customer 139007, had two routes during the day. The orders of customer 139007 were divided into two deliveries. In accordance with that, the working time of the vehicles is updated for vehicles which are found in more than one routing, respectively.

An asterisk marks the fact that one vehicle made 2 deliveries (routes) in one day.
