Pinned topic how to declare à time table with cplex !!

‏2018-07-12T15:17:45Z |

hello,  I have a number of bagags to be transferred by containers for the flights. Each flight has a handling period of bagags, time window [earlist start time , lastest start time ],  i index for flights , so we h ave a handling period S (i) = [minS (i), maxS (i)], for example if number of baggage <50 then S (i) = [30min, 60min] = 60min, if number of baggage between [50,100] then S (i) = [60min, 120min ] = 60min, if the number> 100 then S (i) = [120min, 180min] = 60min, how can i declare this table with cplex without using visual studio .
