Abstract: The problems of production planning and short-term scheduling optimization in petroleum refining industry were discussed and difficulties in implementing production planning and short-term scheduling optimization were also illustrated. The existing techniques for planning and short-term scheduling of refinery industry were discussed. It was pointed out that although there were efficient tools for long-term production planning, there were no efficient techniques and tools for short-term scheduling. It was explained that the existing mathematic programming-based methods for short-term scheduling of refinery industry were computationally prohibited and would not be practical in applications due to the combinatorial nature and large scale of the problem. Thus, perhaps the future trend would be seeking for "heuristic + simulative + enumerative" techniques for the problem.

Key words: oil refinery, production planning and scheduling, hybrid system
