The concept of process system engineering associates operation and management of business and supply chain with the operation of manufacturing execution system (MES)

which requires the adaptive capacity of the constant change of manufacture processes and business processes

on condition that there is a transformation of organizational structure

technological process and product scheme.This paper proposes a configurable MES architecture with three layers (i.e.model layer

cooperation-platform layer and function layer).Firstly

business function is separated from description of factory by the model layer; then

business logic keeps apart from technical support via the platform layer and the overall process collaboration and global optimization can be put into practice by means of the same layer; ultimately

standardized function interface is designed for different products through the function layer.Taking the case of a configurable MES product(SMES)，the paper analyzes the implementation of the configurable architecture so as to adapt to constant change of business process.
