On scheduling model and algorithm of production units of refinery

The production unit scheduling problem is very difficult since complex structures among production units. To get the minimum of total process cost of units, satisfy the main constraints and consider running and storage of units, take the blending components 1 for production targets of units, the production unit scheduling model is developed. A heuristic-based mathematical programming algorithm is introduced to obtain the optimum solution of such model to arrange production reasonably. The results of an example illustrate that it is effective.
