Input Data

Consider the network depicted in Figure Network topology, where each link represents two arcs in opposite directions. Table Maximum incoming/outgoing demand below reports the parameters specified in the data file vpn_data.dat describing the uncertainty set, i.e., the maximum incoming and outgoing traffic demands for each node of the network.

Figure 5: Network topology

Table 7: Maximum incoming/outgoing demand

Node	Incoming	Outgoing
1	120	105
2	34	95
3	35	82
4	101	102
5	78	76
6	75	140

Table Arc costs describes instead the arc cost for every arc (i,j) used in the network (a ``–'' means that no connection exists).

1	–	10	9	12	–	–
2	8	–	10	–	12	–
3	10	7	–	–	9	–
4	10	–	–	–	12	5
5	–	9	8	11	–	12
