The special structure and symbols of Procedure Blueprint make it difficult to develop Procedure Blueprint Supporting Environment. According to the formal features of Procedure Blueprint, a Java-based method is proposed for the construction of Procedure Blueprint Supporting Environment. It contains Procedure Blueprint module, well-formed rules module and code generation module. Procedure Blueprint model and well-formed rules are independent of each other, making Procedure Blueprint Supporting Environment more flexible and adaptable. The method is verified to be able to support Procedure Blueprint modeling as well as generating code. It can implement the primary function of the Procedure Blueprint modeling tool.
