Exact and Heuristic Solutions to Minimize Total Waiting Time in the Blood Products Distribution Problem

Table 9

The experimental result of solving the blood product distribution problem for 24 hospitals.

Number of vehicle (route)		Vehicle no. 1			Vehicle no. 2			Vehicle no. 3
	Vehicle cost*	OFV	Trv Dis.; (km)	Trv Time (hr:min)	OFV	Trv Dis.; (km)	Trv Time (hr:min)	OFV	Trv Dis.; (km)	Trv Time (hr:min)
1	304.75	922.314**	135.4	03:42	—	—	—	—	—	—
2	404.75	386.36	103	02:22	331.15	92.8	02:40	—	—	—
3	504.75	192.10	89.9	02:24	235.7	63.2	01:53	206.5	45.7	01:25

∗The cost of each vehicle was assumed to be 100.
**The Cplex was manually stopped after one hour of running; the reported gap was 10.7%.
