Product scheduling is dynamic, and the buffer that can be used to store the raw materials and semi-finished is limited.
Buffer area is the processing zone which stores the raw materials and semi-finished products near the machine.
The waiting area is a warehouse which stores the raw materials.

Corn is the main raw material for fuel ethanol in China.
Development of fuel ethanol industry expands the market of agricultural products for demand of raw materials.
Theoretical Model Corn is one of the foods in family life, and is also the raw material for production of fuel ethanol, so there is conflict between food and fuel ethanol.
