Hello, I am new to OPL and i am looking for some help in getting this to work..

I am trying to assign channels to base stations but in a random manner/best possible set up.
For example; there are 10 BaseStations, and 6 Channels based on the data that is coming from each base station a channel is turned on...
But i am looking to turn on the channels randomly.. This is the code for what i have done so far, but i need to change it in order for it to be random

dvar boolean BSChannelBaseStationChannels;
subject to {
forall(i in BaseStation)
if(Up_Data[i] <=10){
BSChannel[i][0] == 1;}
else if(10 < Up_Data[i] <= 20){
BSChannel[i][0] == 1;
BSChannel[i][1] == 1;}
else if(20 < Up_Data[i] <= 50){
BSChannel[i][0] == 1;
BSChannel[i][1] == 1;
BSChannel[i][2] ==1;}
}

Up_Data = 10, 10, 15, 7, 12, 6, 5, 30, 8, 9

resulting

BSChannel = [1 0 0 0 0 0
1 0 0 0 0 0
1 1 0 0 0 0
1 0 0 0 0 0
1 1 0 0 0 0
1 0 0 0 0 0
1 0 0 0 0 0
1 1 1 0 0 0
1 0 0 0 0 0
1 0 0 0 0 0];

I would like the BSChannelBaseStationChannel to be a decision variable in the sense that the code will execute so that all constraints are met and the assignment of channels do not void any constraints.

Thank you
