Trouble formulating intervals for a interval scheduling problem

GAMS
1

Hello Internet!


I’m supposed to implement a standart interval scheduling model into GAMS.
However, i dont have the slightest clue on how exactly to begin on that.

The mathematical formulation is stated as followed:

j= Jobs (1,2,…,n)
S= interval following [s(j),f(j)) with s(j) < f(j)
s= start
f= finish
with one ressource. This ressource can only process one job at a time.

Thank you in advance for you help
