The invention provides a sugarcane 
sugar boiling equipment optimizing 
design modeling and modeling method based on the field 
synergy principle. The modeling comprises a subsystem analysis model, a subsystem optimization model and a 
system optimization model. The subsystem analysis model is used for analyzing a single 
physical field to form a module with certain functions; the module comprises 
field analysis, field 
coupling interface analysis, field 
coupling coordination variables and numerical 
simulation analysis. The subsystem optimization model is used for analyzing two different 
physical field coupling coordination in the subsystem analysis model; the target function is a minimized optimized function of the difference between coupling variables and 
shared variables, and constraint condition is the constraint of the 
system; the 
system optimization model is used for overall coordinating the system with a plurality of physical fields for boiling 
sugar coordinately, and constraint condition is consistent constraints of the coupling variables and 
shared variables of each subsystem. By the aid of the modeling method, structure, parameters and operating parameters of the batch-type 
sugar boiling equipment can be designed optimally, quantity of sugar is increased, quality of sugar is improved, sugar boiling time is shortened, and 
energy consumption is reduced.
