The paper puts forward a kind of strategy of optimization theory of blend loading for equipment materials based on the idea of beforehand packing,and makes a system simulation by using blurry clustering analyse and intellectualized arithmetic.

Blend loading for equipment materials is realized with genetic algorithm based on mixed optimization and simulating GASA mixed optimizes strategies.

Study on the alcoholic fermentation using dodecanol as the extractive agent by immobilized yeast with alginic acid and polyvinyl alcohol as the mixed carrier was curried out.
