The invention provides a layering modeling and optimizing method targeting a complicated manufacture
system, which is used for the total target optimization of a layering manufacture
system comprising a plurality of elements. The method comprises the following steps of: (1) dividing the manufacture
system into a layering system comprising a plurality of elements, wherein each element comprises a computer and carries out
data exchange with other elements by a computer interface; (2) confirming the reaction, a contact variable and a
local variable of all the elements and leading all elements to contact mutually; (3) establishing models of all the elements, which comprise an optimizing design model and an analyzing model; and (4) carrying out optimization solving on the models of the layering manufacture system. The invention can realize the modeling and optimizing unification of the layering manufacture system comprising the elements and has the advantages of consistence with the traditional manufacture system topological structure, capability of
parallel optimization, unlimited layering grade number, and the like, and all the elements can select different optimization algorithms, therefore, different optimization algorithms can be integrated into one system.
